[Travis Kirstine via MapServer-users]

First thought is to check if the table has a spatial index.

Re: [MapServer-users] Suppress queryable=1 for wms_layer_group [SEC=OFFICIAL]

[Travis Kirstine]

 Hi Kathleen,

I haven't experimented with GROUPed layers but have you looked at
*wms_enable_request* (or *ows_enable_request*) defined in the METADATA
section of the layer

"wms_enable_request" "* !GetFeatureInfo"

See docs: https://mapserver.org/ogc/wms_server.html#web-object-metadata

I don't think you can store index files / VRTs in a memory cache.

Re: [MapServer-users] Ask for advice on Caching large layers on high zoom level

[Travis Kirstine]

I've found the other limiting factors are disk speed (SSD vs HDD) and cache
type.  SQLite can be easy to manage but the write locking during inserts
can really slow things down (adding more cores won't help in this case)
when compared to writing a simple disk cache.

I agree with Scott in that if you are using COGs you shouldn't really need
MapCache as you could look at alternatives to serve this data out as is.

Re: [mapserver-users] Question about importing xml/json data from api

[Travis Kirstine]

Liron,

Since MapServer is built with GDAL / OGR you connect to most common formats
without parsing, see https://www.mapserver.org/input/vector/ogr.html.
However this does not include hand rolled JSON / XML, if possible retrieve
GeoJSON or some other GDAL / OGR supported format from the API.  You may
want to go through an extra step(s) of converting the data to a format that
supports spatial indexing (like shapefile or geopackage) if working with
large datasets.  Most of this can be done using a shell / batch scripting
and command line tools (ogr2ogr and shptree).  BTW ogr does support direct
connection to some API - like an ESRI feature server which can make the
conversion "easy", however not all OGR supported formats work with MapServer

https://gdal.org/drivers/vector/index.html

In summary use internally tiled geotiffs with overviews using gdaladdo in

[mapserver-users] MapCache dimensions with MapServer run time substitution

[Travis Kirstine]

Is it possible to utilize mapcache regex dimensions with mapserver run time
substitution (wms) to create a more dynamic and generic tile service

Here is my basic configuration for mapserver and mapcache, I can't seem to
get it working with QGIS when connecting to the WMTS

For example I use run time substitution with my PG DATA settings

  LAYER
NAME "sub_layer"
...
VALIDATION
  'layer_table' ^.*$'
  'layer_class' '^.*$'
END
CONNECTIONTYPE postgis
CONNECTION "port= user=user password=pw dbname=db host=mydb"
DATA "the_geom from (SELECT gid, ms_color, the_geom FROM %layer_table%
WHERE class='%layer_class%') AS foo USING UNIQUE gid using SRID=4326"
 
  END

I set my MapCache config up with the same runtime variables as dimensions

   
  
 
image/png
true
sub_layer
 
  
  
 http://testserver.com/cgi-bin/wms?

Re: [mapserver-users] Bewbie question about MapServer and WPS

[Travis Kirstine]

Petros

I'm not sure if MapServer is what you are looking for as I is generally
used the the creation and transfer of maps and it sounds like you are only
concerned with retrieval of statistical information.  MapServer probably
could be used for the application you describe but it would be easier to
simply use a WPS  service of some sort (https://pywps.org/).  Alternatively
you could look at using postgresql with the geo-spatial postgis extension
to perform your analysis any develop your own interface using whatever
language you prefer.

Re: [mapserver-users] MapCache clusters

[Travis Kirstine]

I don't think multiple instances of MapCache will help for seeding, in
general most of the seeding time depends on the zoom level, with each
higher zoom level taking 4 x the time as the proceeding zoom level (e.g.
zoom 20 take 4 x the time to seed as zoom 19)  .  This can vary depending
on your source service as there may be certain map scales / zoom levels
that take longer per tile to render due to expression, labels, # of
features etc... If you were to seed two levels for each mapcache instance
you still would be waiting for the higher zoom levels to complete.   Using
multiple load balanced mapserver nodes across multiple VM may improve
things a bit however if all the VMs are hosted on the same physical server
this may be slower overall.  For seeding I have heard you can use 2x the
number of cores so you could set up a single mapcache server using -n 16
pointing at the load balanced source.

Re: [mapserver-users] mapcache seed speed optimization

[Travis Kirstine]

I may not be unrealistic for it take mapserver to 4-6 seconds to generate
4096px image depending on the amount data being rendered and the complexity
of your styles / expressions / labels.  If your mapserver is able to
generate a 1024x1024 in under a second that is pretty good.  Like Jukka and
other suggest I would look at translating the files to shp files with
spatial indexes or postgis tables with spatial and attribute indexes if
necessary.  Preprocessing the data (simplification / prefiltering / point
thinning cluster) and using SCALETOKENs to reference different source
layers at different scales can lead to big performance boosts at the
mapserver end.

For us the biggest limiting factor has been the write blocking to sqlite
cache when seeding tiles, if you increase the number of threads / process
in mapcache seed those process will just end up waiting to write to the
cache.  You can generally figure out what the max number of processes the
cache can handle by running a seed on a test area and look at the number of
tiles seeded per second, as some point -n will have no effect which your
process are just waiting to write the cache.  I would look at using this
method to test sqlite vs disk or other backends.  The GeoTiff cache may be
promising as it appears to be non-blocking but experimental...

We use a riak cache with a riak leveldb backend which works well for us but
is a bit of a pain to manage as it difficult to delete objects so it's not
great for caches that need to be refreshed.

Finally you may want to test MapProxy as an alternative to MapCache (we use
both).  MapProxy supports a non-blocking compact cache that could solve
your inode problem

[mapserver-users] wms servers html template output

Hi all,

I'm struggling a bit with using a generic template for html getfeatureinfo

attribute field names and values for any layer.  I don't want to create a
separate template for each layer.  Thanks

You can set the

Re: [mapserver-users] mapcache seed slow

[Travis Kirstine]

The time you have indicated seems excessive to seed the UK. My guess is
that the current process it seeding the extents of your grid (world?) but
default.  I've seeded the province of ontario 1 million km2 z0-17 in about
2 weeks using a sqlite cache

Ramping up the -n will only bottle neck the process more (same with the -p
flag) the limiting factor is SQLite and it limitation on concurrent writes
(I use -n 4).  I've noticed that if you try to use other sqlite3 journal
modes you can degrade performance (
http://osgeo-org.1560.x6.nabble.com/mapcache-sqlite-cache-large-wal-files-and-blocked-checkpoints-when-seeding-td5377571.html).
I would just use most basic cache config as a starting point.  BTW using
SSD should increase the SQLite writes as well (if you are lucky enough to
have them)

   
  ./{tileset}.sqlite3
   

There are a few things that you could do when seeding to speed up the
process:

Use the "restricted_extent" parameter in the tileset grid to limit the
number of tiles

Example
   
 ontario_2018_wms
 sqlite
 gmaps
 mixed
 5 5
   

Use a polygon shapefile (or other ogr datasource) to limit the seeding
using the -d flag in mapcache_seed command (note the projection of the
datasource should be the same as the grid)

Use a larger metatile when seeding (-M flag override in command line).
Mapcache will "bulk" insert the resultant tiles based on the metatile -
if 5 5 mapcache will insert 25 tiles at a time if
8 8 it will do 64 (I think this is the way it works).
The limiting factor here is trying to balance this with your source WMS
performance.  I use 8,8 when seeding

Re: [mapserver-users] Mapcache - best way to find broken or white tiles in a service?

[Travis Kirstine]

You shouldn't have any cached "broken" tiles unless your source WMS is
generating the white images (metatiles).  I believe MapCache will generate
a 404 and return a empty tile if configured.  This may be the white tiles
you are seeing.

   
   report

It can be very difficult to locate and clean up tiles from a cache, the
easiest method and in some cases the fastest is simply to create a new
cache and delete the old one.  One alternative is to use the mapcache_seed
command line tool to either -f force the creation of new tiles or use the
-mode delete option to delete the tiles from the cache.  BTW you can use a
polygon (shapefile) with mapcache_seed to only update / delete the desired
area using the -d flag.

Also if you are using a disk cache you might be using symlinks which will
allow mapcache to "reuse" blank tiles.  If this is the case you might need
to find / delete the symlinks rather than a "file"


   
   /tmp

Re: [mapserver-users] Raster performance hints

[Travis Kirstine]

What you describe is pretty much the approach we take.  If you are using
geotiffs ensure that they are internally tiles (-co TILED=YES) and the you
are creating a shptree index on the tile index as noted in the docs.  At
some point you may want to consider creating a lower resolution mosaics of
coverages and using GROUPS and MIN/MAXSCALEDENOM to load the layers at
different scales.  Make sure to declare the layer's extent as well

Something like:

LAYER
NAME "full_res_10cm_tiles_withovr"
EXTENT 607500.00 4824000.00 654000.00 4859500.00
TYPE RASTER
PROCESSING "RESAMPLE=AVERAGE"
TILEINDEX /maps/tindex.shp
TILEITEM location
GROUP "my_photo"
MAXSCALEDENOM 1
OFFSITE 0 0 0
METADATA
"wms_extent" "607500.00 4824000.00 654000.00
4859500.00"
END
PROJECTION
"init=epsg:2958"
END
END
LAYER
NAME "resampled_2m_tiled_bigtif_withovr"
EXTENT 607500.00 4824000.00 654000.00 4859500.00
TYPE RASTER
PROCESSING "RESAMPLE=AVERAGE"
DATA /maps/2m_overall.tif
GROUP "my_photo"
MINSCALEDENOM 1
MAXSCALEDENOM 65000
OFFSITE 0 0 0
METADATA
"wms_extent" "607500.00 4824000.00 654000.00

Re: [mapserver-users] mapcache fastcgi

[Travis Kirstine]

My experience with SQLite is that it is significantly slower than a disk
based cache.  My guess is this is related to how mapcache structures the
transaction and inserts into the sqlitedb.  It appears that the mapcache
creates a transaction based on the  defined in the config, if the
metatile is set to 5 5, mapcache will create a transaction with 25 inserts
per process. Problems seem to arise when multiple threads / processes
attempt to concurrently seed the cache and are backlogged / waiting due to
a transaction in progress.  Disk cache appear to be only limited based on
disk io.

Lars,
Sorry for the side questions

Is there any performance benefit (specifically seeding) in using the
x/ycount parameters?

Thanks

[mapserver-users] mapcache - sqlite cache large wal files and blocked checkpoints when seeding

[Travis Kirstine]

I've set up a sqlite3 cache using addition pragma statements to set journal
mode to WAL and journal mode to normal.

   
  1
  wal
  ./{tileset}.sqlite3
   

These setting "should" increase performance however I've noticed that when
seeding the cache the wal file is growing excessively over time (+50GB)
which would result in slower reads.  I believe this is being caused by
seeding the cache using multiple threads (-n 4) causing checkpoint
starvation as defined here (https://www.sqlite.org/wal.html) as:

"
Checkpoint starvation. A checkpoint is only able to run to completion, and
reset the WAL file, if there are no other database connections using the
WAL file. If another connection has a read transaction open, then the
checkpoint cannot reset the WAL file because doing so might delete content
out from under the reader. The checkpoint will do as much work as it can
without upsetting the reader, but it cannot run to completion. The
checkpoint will start up again where it left off after the next write
transaction. This repeats until some checkpoint is able to complete.

However, if a database has many concurrent overlapping readers and there is
always at least one active reader, then no checkpoints will be able to
complete and hence the WAL file will grow without bound
"
This is verified by manually attempting to force the checkpoint in the
command line while the seeder is running :
sqlite> PRAGMA wal_checkpoint(TRUNCATE);
1|-1|-1
The first column is usually 0 but will be 1 if a RESTART or FULL or
TRUNCATE checkpoint was blocked from completing, for example because
another thread or process was actively using the database.

[mapserver-users] calculating min / max scaledenom based on projection

[Travis Kirstine]

Hi all,

We've been using mapserver as a WMS server and need to determine (outside
of mapserver) if a requested image contains layers defined in the getmap
request based on the layers min/maxscaledenom setting in the mapfile.  If a
request to the WMS is in the MAP SRS then we simply calculate the image
scale using a method like the one used in the mapscale.c msCalculateScale
and compare it to the MaxScaleDenom defined in the GetCapabilities and
everything works as expected.

The issue we have is that if the WMS GetMap SRS projection does not match
the native projection of the layer the maxscaledenom will vary.  For
example if the layers is in web mercator projection and has a maxscaledenom
of 25000 but the request is made in EPSG:4326 geographic the layer will not
be drawn above a scale of ~ 1:16000 in QGIS.

How can I calculate what 25000 equals for other SRSs?

How does mapserver calculate the min/max scaledenom for various projections
/ units?

Thanks

[mapserver-users] mapcache error -1 on seeding transfer

like this:

Retry 1 in riak_has_tile for tile gmaps-20-293584-667321 from cache riak due to 
error -1

What is error -1?
Is it possible to restart the transfer from the last failed tile?

The logging (-L) of the failed transfer doesn't appear to work for this type of 
failure

The reprojection is done inside MapCache, i.e. as a client of the original 
tiles. You don't need an additional WMS :)

Re: [mapserver-users] mapcache question

I believe that there still would be an issue as the reprojection from X to Y, 
the reprojection would need to be done on the source WMTS side.  I guess you 
could proxy the source WMTS using mapserver with the gdal mini driver  and 
reproject to create a WMS to feed mapcache?

Jukka,
in master, there is also support for any GDAL dataset as a mapcache source 
(i.e. in addition to wms). If you use that in addition to a GDAL TMS/WMS/WMTS 
minidriver you'll be able to reproject/store third party tiles on the fly.

Re: [mapserver-users] mapcache question

[Travis Kirstine]

Jukka,

According to the docs mapcache only support WMS as input.

" A source is a service mod-mapcache can query to obtain image data. This is 
typically a WMS server accessible by a URL. (There are currently no sources 
other than WMS implemented, though others may be added later if the need 
arises)"

If this is still true then your proposed chain will not work.

MapProxy will support a tiled source and I know TMS works  (not sure about 
WMTS) and handle the reprojection

Mapcache was compiled, and is working a-ok with demo data. But I have trouble 
to configure mapcache to work as a part in the above chain. As planned, 
Mapcache should work as a WMTS client down towards target 1 and WMTS server up 
against target 3, ie. kind of a proxy with crs reprojection and basic auth. 
Anyway, does this make any sense at all, or is the draft totally irrational?

If the draft is reasonable, could you give some hints on how to proceed related 
to configuration with mapcache.xml?

Re: [mapserver-users] ogrinfo : couldn't fetch requested layer

[Travis Kirstine]

Are you trying to read a CSV file?  You shouldn’t need a odbc connection to do 
that.  What does your vrt file look like?

Hello,

I have created an odbc connexion named basol to use csv and vrt files in 
Mapserver. Ogrinfo can open basol (using driver ODBC successfully)

`ogrinfo ODBC:@basol test.csv

but says "FAILURE : Couldn't fetch requested layer test.csv"

Is it a problem with system environnment variables ? Does it mean that 
mapserver will not be able to draw the layer later ?

Re: [mapserver-users] Mapcache: Can't get transparency from WMS layer

[Travis Kirstine]

In your WMS requests logs (i.e.  Apache) does mapcache make a request for a 
transparent image and is the image returned transparent,   if you copy the 
mapcache generated request into your browser or fetch the wms via curl is the 
image transparent?

Hello,

I have a Mapserver up and running, sharing WMS layers. Those layers are 
rendered with transparency, but not with Mapcache. 

I can add the layers in QGIS, and the caching works. But not the transparency.

I tried to add  tag into the  tag of the source. No 
reference to JPEG format, only PNG.

Here is my config file: http://pastebin.com/gHx0eiw3

Re: [mapserver-users] Mapcache - merge multiple source in one tileset?

The danger with this method is that under high loads you can exceed the

Hi,

thanks for this idea. If I understand correctly, this would mean creating two 
source tilesets and then generate a third one, where I call mapcache wms 
requesting these two layers.

I'll give that a try. Cheers, Michael

Re: [mapserver-users] Multiple MapCache configuration files

You can create multiple aliases in apache

IfModule mapcache_module
   Directory /path/to/mapcache
  Order Allow,Deny
  Allow from all
   /Directory
   MapCacheAlias /mapcache_1 /path/to/mapcache_1.xml
   MapCacheAlias /mapcache_2 /path/to/mapcache_2.xml
   MapCacheAlias /mapcache_3 /path/to/mapcache_3.xml
/IfModule

 Hi,

 As per the configuration guide I have a single xml configuration file for
 all MapCache layers. This is set in httpd.conf (I'm using ms4w, and running
 on a Windows server):

 IfModule mapcache_module
Directory /ms4w/apps/mapcache/
   Order Allow,Deny
   Allow from all
/Directory
MapCacheAlias /mapcache C:/ms4w/apps/mapcache/mapcache.xml
 /IfModule

 However I'm using MapCache on a development server and hosting several
 different applications. I create the xml file dynamically for each
 application, however with this approach I either have to change the above
 path and restart Apache, or merge all the xml files together to a single
 file.

 Is there anyway to change which xml file is used using a querystring, or
 is there any other suggested approach to handling multiple mapcache.xml
 files?

 Seth

Re: [mapserver-users] Mapcache Question

[Travis Kirstine]

Tim,

MapCache Is simply a tiling server.  It will take images from a source and
store them in a cache.  These tiles are exposed as services to clients -
WMTS, WMS, TMS etc...  MapServer on the other hand will read source data
(GIS files / database) and render images based on rules defined in the
mapfile.  These images are used as the source for MapCache.

On Wed, Oct 1, 2014 at 5:58 PM, Tim Nasman tnas...@rollingleaf.com wrote:

 I have read through the Mapcache documentation but I feel like I am
 missing some basic elements to how it works.

  I am using Mapcache to display a mbtile that I have created. Now from
 what I understand, my mapcache .xml will list out the parameters of the
 mbtile and then I add a layer within my mapfile referencing the .xml which
 I should then be able to to use as WMTS using openlayers. I just haven't
 grasped how mapcache and mapserv work together so any clarification would
 be helpful. Thanks for your time.

[mapserver-users] MapCache inverted Y values

I just configured mapcache using a grid using 512 512 size.  Everything
seems OK however when I view the resultant tilesets in the demo map viewer
they have a inverted Y value, the latitudes are negative values when they
should be positive.  Do I need to create a custom cache to handle tile
sizes other that 256?

Re: [mapserver-users] TileIndex - accuracy and truncation ?

[Travis Kirstine]

Could it also be the resampling of the image and or an issue with the PNG
format?  I would try tiled geotiffs.

 Hi,



 For performance reasons, I've (used FME to) split a large PNG into 450
 small tiles, serving them with a Mapserver tileindex as a WMS service to a
 web solution.



 Howeever, white lines appear between some of the tile rows (not all) at
 some scales (not all).



 I've looked deeper into the WLD files for the individual tiles, and found
 that the calculations are accurate to 1/10 of a nanometer. At least if one
 uses all 10 decimals.



 Tiles are 2254 pixels high, and (as per the WLDs below) 6138899.3169212583
 - 0.0204375000 * 2254 = 6138853.2507962583 (almost equal to
 6138853.2507962584)



 Which leads me to suspect that some sort of truncation goes on, yielding
 some sort of rounding error.



 Do anyone know whether the tileindex calculations truncates any of the
 values in the WLD files ? And if so, by how much ?



 Cheers.

 A typical map picture with a white line can be seen via this link:

 Here's the WLD of the two tiles displayed in the picture:



 Upper tile WLD:

 -0.0204375000

 Ps! As I wrote previously, I'm using FME to create the tiles. So I have
 little control over the actual coordinate and pixel values, and only
 specify the number of tiles I need. So manual truncation is not really a
 viable option.

[mapserver-users] fastcgi with multiple WMS services

[Travis Kirstine]

We are currently running a number of (several hundred) WMS services on a
single server using CGI.  Each service is configure using its own mapfile
with corresponding CGI script.  All services are pulling source data from
PostGIS tables.  In this type of use does it make sense to use fastcgi and
are there any dangers - high memory usage, multiple open PG connections?

Re: [mapserver-users] mapcache groups

[Travis Kirstine]

I was hoping to hit MapCache directly.  We have done something similar
using  MapServer with a WMS connection to MapCache with multiple layers /
tilesets defined in the getmap request.

I was hoping for something like

tileset name=tileset1 group=AllLayers
  sourcesource_wms1/source
  cachedisk/cache
  gridgmaps/grid
  formatmixed/format
/tileset
tileset name=tileset2 group=AllLayers
  sourcesource_wms2/source
  cachedisk/cache
  gridgmaps/grid
  formatmixed/format
/tileset

Where a WMS getmap request could be made using the layer=AllLayers

Do you have the wms service enabled in the mapcache config file

BTW ArcMap 10.1 can access a mapcache WMTS as well (faster and less load)

  You may have this already, but I know that to get ArcMap to read
 MapServer
  WMS you must have a title and srs definition in the map file's layer
 metadata.
  For example:
 
METADATA   # stuff for WMS to make ArcMap happy
  wms_title  Layer Name # REQUIRED
  wms_srs   EPSG:3739  # REQUIRED

 I have mapserver rpms installed on a Fedora 18 system. Mapserver binaries

 What is the preferred (and more elegant) way of putting relevant binaries

 Or is there yet another alternative?

 One foreseeable issue is the maintenance/updating of binaries via RPM.

[mapserver-users] mapcache - multiple resolutions for the same grid

[Travis Kirstine]

I have set up mapcache with a generic grid for all my caches.  The grid has
resolutions defined for zoom levels 0-21, however depending on the
resolution of my source data the tileset may only be seeded to level 19.
The tileset no longer has the ability to connect to the source.  As a
result blank images are displayed the when a client using the mapcache WMS
zooms in beyond the max resolution.  Is there a way to address this without
creating additional grids?

[mapserver-users] mapcache make issues

I've been having issues with the make of mapcache.  The configure seems to
go off without a hitch but the make generates several skipping incompatible

[mapserver-users] Mapserver CSRS support

[Travis Kirstine]

I have issue with my WMS service when using a source raster layer that is
in EPSG:2958 - NAD83(CSRS) / UTM zone 17N srs. The issue is that Mapserrver
(proj) does not apply a gridshift when requesting the layer in a different
projection - UTM z17n NAD83.  I have a gridshift file for this
transformation however there is no way to apply it to the output that I am
aware of.

[mapserver-users] Image quality

[Travis Kirstine]

I am having issues with the output image quality of MapServer.  I have
a mapserver set up as a wms server up high res orthophoto images.  The
images are in tiled geotiff format with JPEG / YCBCR compression with
internal gaussen overviews and referenced using a tile index in the
mapfile with the PROCESSING RESAMPLE=BILINEAR directive.  Mapserver
5.6.7 is set up using AGG with imagemode RGBA.  I have noticed that
the images generated have aliasing in areas of high contrast when
viewing at various scales (full res seems fine).  What is the optimal
setup to reduce this effect?

Re: [mapserver-users] Re: Mapserver + mapcache + Google Map

[Travis Kirstine]

It appears that mapcache is trying to write to the grid g which is
not defined.  Are you looking to create tiles is a 900913 projection?
I would try removing the gridWGS84/grid and gridg/grid
elements restarting / reload apache and see what happens (I'm not sure
if a tileset can support multiple grids).

 Thanks for the suggestion.  Commenting out the source block disables the WMS

 However, the error reporting seems to be broken.  Setting

 You can do this by commenting out the source block from the tileset once 
 the wanted tiles have been created. You'll probably also want set error 
 reporting to return blank images from that stage onwards.

 We have a fully seeded cache that was fully seeded to a polygon outline.
 The intent is to serve the tileset through a variety of services (WMS,
 TMS) using mod-mapcache.



 Tiles that are outside the polygon outline but still within the
 polygon bounding box should be blank tiles.  However, a request for
 one of these tiles results in a call to that tileset’s WMS source.
 This creates considerable overhead by starting up MapServer and
 writing the resulting tile to the cache.  Is there any way to disable
 the WMS calls for these blank tiles, and instead short-circuit the
 request to return a blank?  That is, once a tileset has been fully
 seeded, is it possible to disable any further calls to the WMS, so
 that requests for tiles that are not in the cache return a blank?

Is it possible to retile cached images.  Our data is at a 1:1

possible to take the cached level 19 tiles and retile them to level 20

 Travis,

 In the past I have used NFS in a custer and in general the performance was
 very bad when compared to SMB. Now this was a few years ago, ie: not using
 mapcache, but my experience was that we ran into a few issues with NFS:

 1. NFS CPU overhead was significantly more
 2. connection recovery was poor if a server was pulled from the cluster and
 added back again (ie: recovery after an error condition)
 3. the protocol seems to have a lot more over head

 So, this discussion inspired me to completely rework the locking
 mechanism in mapcache, to stop relying on file locks which have their
 quirks on network filesystems.
 I have tried using multiple apache instances configured to used a
 SMB-mounted lock directory and hammered both instances on unseeded
 identical area to force locking, and ended up with absolutely no
 duplicate wms requests or failed requests for the clients.
 The code is committed in trunk. Thanks for bringing this up, this
 allowed me to really simplify the locking code and remove a lot of
 unneeded stuff :)

 Andreas and Thomas

 Thanks for you responses,  I have discussed this with some of our IT
 staff and they had similar solution as Andreas using gfs.  Their
 comments are below:

 I suspect this scheme is not reliable over NFS. The problem is the
 directory updates are not synchronized across multiple nodes. I had a
 similar issue with the IMAP E-mail protocol. Our workaround currently
 is to force each user to leverage a single server.

 Ref:
 http://wiki.dovecot.org/NFS

 Seems like there's some tweaks to disable directory attribute caching
 but this can trigger slower performance.
 Only workaround is to use GFS which I found to have it's own issues.

 As Thomas noted, if the lock files are created on a shared filesystem

 (read the docs carefully!) there's no reason why it should not work.

Re: [mapserver-users] Re: QGis 'Zoom to best scale' Not Working

[Travis Kirstine]

Are you requesting the MyGroup layer or MyImage, I'm not sure if
the group inherits the layer metadata (I'm sure someone on the list
knows).  I have noticed that when adding grouped layers in QGIS the
zoom to extent does not work however it will work when individual
layers are added.

 Thank you. I added wms_resx and wms_resy to my mapfile with reasonable
 values (and some unreasonable ones, just as tests). This makes no
 difference. When I make a GetCapabilities request, the layer's bounding
 box is correct but it does NOT contain the resx or resy settings, as I
 believe it should.

 I don't know if this is a problem in my mapfile or in MapServer. My
 mapfile layer looks like this (file names changed for proprietary
 reasons):

 Hi,

 WMS does not advertise by default the native resolution of the data.  I
 have never tried but perhaps adding wms_resx, wms_resy metadata into
 layer metadata would add that information into GetCapabilities
 http://mapserver.org/ogc/wms_server.html.
  I do not know if QGis can utilise that information even if it exists.

 I'm not sure if this is a QGis problem or a problem with my
 Mapserver-generated WMS layer. When I load a WMS image in QGis,
 everything
 works as expected except when I select 'Zoom to best scale' I get a
 Mapserver error stating that the bounding box is illegal. And it is - the
 bounding box corner points in the getmap request are identical. This
 selections is supposed to zoom in so the pixels displayed are 1:1 or 100%

 A look at the capabilities request returned by Mapserver and the mapfile
 and
 images involved don't show anything obviously wrong. Is it possible that
 QGis is sending the wrong request? Or is something missing from either
 the
 capabilities document or the mapfile layer?

 I'm not really sure where to start looking to isolate the problem. Note
 that
 if I load images directly instead of through Mapserver WMS I am able to
 zoom
 to scale without any problem, which suggests a problem with Mapserver,
 likely in the mapfile. I am using VRT files as intermediaries between the
 Mapfile and the underlying NITF files; it seems that Mapserver should be
 using the affine transform contained in the VRT to determine proper
 scaling,
 but I'm not sure if that is sufficient. Are there arguments that need to
 be
 placed in the Mapfile metadata to help WMS generation along? Or something
 that would cause items in the capabilities document to be left out?

 Using QGis 1.7.0 on Linux.

Re: [mapserver-users] mapcache in a cluster

Thomas,

We have been running into some performance issues mapcache and nfs.
We feel the issue may be related to how nfs locks files/directories
compared to smb.  We are trying a few thing on our end (disable
locking / nfs4 etc).  Do you have any ideas?

Re: [mapserver-users] mapcache in a cluster

[Travis Kirstine]

When running the seeder (I haven't tested on the fly generation) the
process is running extremely slow.  The seeder is launched using all
available cpus (24) on the server.  We are running MapServer as the
WMS source.

When I launch the seeder using a cache on the same file system the
seeder will spawn 18-24 concurrent WMS request and  mapcache_seed will
be running at 250-350 % CPU.

If I launch the same seeding process using a NFS mounted cache the
performce will drop - The WMS requests will drop to only one request
(if that) and map_cache will be running at less than 60% CPU. The
server is basically idle.

I rechecked the mapcache configuration script and we are writing the
lock files to the same mounted directory as the cache, I'm not sure if
this could be a issue.  I will try writing the lock files locally to
see if this has any effect.

Regards

 Travis,

 Are you using full paths to the files in question.  I vaguely suspect
 that the fopen()s used in path construction within MapServer do
 not work properly with large files (4GB).  If that turns out to be
 the issue please file a ticket on it.

 The work around would be to use a full path instead of depending
 on SHAPEPATH or map relative path construction.

 Best regards,

I think you have a issue with your regex the brace / bracket is unbalanced:

[mapserver-users] nodata transparencies

[Travis Kirstine]

Hi All

I have a raster layer of 8 bit RGB orthophoto with the source data as
GeoTiff tiles (tile index) .  Some of the source images have the
nodata (0,0,0) defined in the metadata some do not.  Can MS
automatically determine the nodata and use that as a transparency for
each image in the tile index?

The issue that I am having is that I have a large coverage area that
is composed of  RGB tiled uncompressed geotiffs with real nodata
values at the edges of the coverage and tiles on the interior of the
coverage are RGB tiled compressed ycbcr geotiffs with no nodata
defined.   If I use the OFFSITE 0,0,0 parameter in my mapfile the
resultant images will have holes on the interior of the image ().

I have tried scaling the images however it appears that JPEG
compressed YCBCR images do not scale well

Re: [mapserver-users] MapCache - failed to remove lockfile error

Thomas,

The latest version (as of last week) seems to have fixed the lockfile
issue.  We are running into issues with the linking of transparent
tiles:

failed to link tile
/home/caches/0837DURH_cache/googlemaps_grid/21/000/590/400/001/333/608.xxx
to /home/caches/0837DURH_cache/googlemaps_grid/blanks/.xxx: No
such file or directory

We are running the seeder with 24 threads (all cores on the server).
Could there be a issue with linking to the same file simultaneously?

Re: [mapserver-users] MapCache - failed to remove lockfile error

[Travis Kirstine]

We checked out a version of mod-geocache on sept 22, my guess is that
it is version 0.4x.  We will check out the latest mapcache version
from the mapserver trunk.

[mapserver-users] MapCache - failed to remove lockfile error

[Travis Kirstine]

Hi All,
I hope this is the right spot to post MapCache questions.  I had
seeded a large area and receive the error failed to remove lockfile.
 It appears that this error(s) happens at the end of the seeding but
it is hard tell as the process has been running for a few days.  Does
this error kill the seeder process or is it simply a warning?

This doesn't seem to be a issue, I have lots of inodes left.  It
appears that the error occurred when generating (linking)  areas with

[mapserver-users] UNION raster layers returns blank image

[Travis Kirstine]

Hi All,

I have been having some issues using the UNION option in the mapfile.
I'm trying to set up a WMS server with several source raster layers
and provide them all as a single union layer to the client.   I don't
want the source layers visible in the GetCapabilities, only the union
layer so I have been using a combination of the own_enable_request and
CONNECTIONTYPE UNION.  It seems to work in the GetCapabilites, only
the union layer appears however only blank images are returned from
the GetMap requests.  The layers portion of my mapfile is below, I
have set the ows_enable_request * in the WEB METADATA.  Any help
would be much appreciated

[mapserver-users] mapfile config options - scan directory

[Travis Kirstine]

Hi All,

I saw Frank's GDAL performance tips presentation at FOSS4G and he
mentioned that a config option in a MS mapfile could be set to stop
GDAL from scanning for auxiliary files when using external tiling.  I
have looked around in the MS documentation and GDAL and cannot find
the option.  If this option was set would it stop GDAL from using
external worldfiles / overviews?

Hi all,
I have been trying to install Mapserver 6.0 and I am running into the
following error.  I thought this could be related to a older version
of GEOS / GDAL so I installed gdal 1.8 and geos 3.2.2.  Any ideas

[mapserver-users] re mapserver 6.0 make error

[Travis Kirstine]

The issue was related to having the Extra Packages for Enterprise
Linux (EPEL) repository configure, this contained a version of GEOS,
removing this version fixed the issue - I hope.

[mapserver-users] hiding / combining layers in a wms service

[Travis Kirstine]

I am trying to combine several layers into a single layer for a wms
server while using the wms_layer_group option.  I have resampled my
source tifs so that is displayed based resolutions and map scale to
hopefully improve performance.  The drawback to this is that clients
see all layers.  Is there a way to group all layers into one while
keeping the hierarchy that is created with the wms_layer_group.

[mapserver-users] wms version 1.3 bbox problems

[Travis Kirstine]

Hi,
I'm currently running ms 5.4.2 and am having difficulties with wms
version 1.3.  I am using MapInfo as the client and it seems that it is
hard coded wms version 1.3 if available from the service.  It seems
that there is bbox issue when passing GetMap request to the service.
Is there something I have to add to the mapfile to indicate the
correct bbox or projection?

Re: [mapserver-users] wms version 1.3 bbox problems

It appears that the bbox in the reverse order for 1.3, is there a work around?

 Hi,

  What does the GetMap request looks like, specifically the bbox coordinates
 and the projection?  For wms 1.3.0, bbox coordinates are expected for
 projections such as espg:4326 to use the inverse axe order (lat/long instead
 of long/lat)?

 regards,
