Re: [mapserver-users] mapcache question
I was not able to solve the problems on fresh CentOS 7 environment with all the latest libraries/dependencies included. on old test environment, I did upgrade/build to gdal 2.1.1 and also latest mapcache master. this environment is working as one would expect according given instructions in http://mapserver.org/mapcache/install.html. so basically now I'm back on the already achieved square 1, with that difference, that the versions of mapcache and gdal are upgraded. ==> now I'm able to proceed with Thomas suggestion with GDAL data source and GDAL WMTS driver. From this point of view, this post is completed, thus, more questions will come!

Hi, Actually it just says there is an error in your mapcache.xml file (or maybe apache can't even access/read it).

Re: [mapserver-users] mapcache question
There's no on the fly reprojection of an exisiting cache, so to be able to serve the same tileset/layer under multiple SRSs you'll need to have one cache per srs/grid. -- thomas On 25 August 2016 at 15:33, Travis Kirstine wrote: > Unrelated question: Can mapcache handle multiple srs in a WMS service (out)? > > -Original Message- > From: thomas bonfort [mailto:thomas.bonf...@gmail.com] > Sent: August-25-16 8:56 AM > To: Travis Kirstine > Cc: Lime, Steve D (MNIT) ; Jukka Sirviö > ; mapserver-users@lists.osgeo.org > Subject: Re: [mapserver-users] mapcache question > > The reprojection is done inside MapCache, i.e. as a client of the original > tiles.

Hello ALL!
I dig into MapCache now and my modest comprehension is:
1) MapCache uses Mapserv for seeding tiles or more exactly -
sends WMS request to Mapserv for getting a map:
section in a mapcache.xml file
2) Ol uses MapCache for rendering that tiles or more exactly -
sends WMS(or other) request to MapCache:
new ol.layer.Tile({
source: new ol.source.TileWMS(({
url: 'myhost/mapcache/?',
params: {'LAYERS': 'mytileset'},
serverType: 'mapserver'
}))
})
where
/mapcache/ is path to a mapcache.xml(aliased through Apache),
'mytileset' is section in a mapcache.xml file
3)The Seeding and the rendering needs other configuration of
mapcache.xml file(it is needs clarification).
4)The seeding may be through:
mapcache_seed -c mapcache.xml -t mytileset-g mygrid
or
during a certain map area is requested by client (it is needs
clarification).
Yes, this seems correct. I will not that you CAN NOT use mapcache_seed
AND web requests TOGETHER as they do not use compatible locking
mechanisms. So either use mapcache_seed before you deploy or use the web
requests to dynamically seed the cache. You can use mapcache_seed to do
a partial pre seeding (like rectangles around major cities) then change
over to web request which will generate tiles as needed in the remaining
areas.

Thanks for any correction.

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.

Re: [mapserver-users] Mapcache Question
Hello ALL!
I dig into MapCache now and my modest comprehension is:
1) MapCache uses Mapserv for seeding tiles or more exactly -
sends WMS request to Mapserv for getting a map:
section in a mapcache.xml file
2) Ol uses MapCache for rendering that tiles or more exactly -
sends WMS(or other) request to MapCache:
new ol.layer.Tile({
source: new ol.source.TileWMS(({
url: 'myhost/mapcache/?',
params: {'LAYERS': 'mytileset'},
serverType: 'mapserver'
}))
})
where
/mapcache/ is path to a mapcache.xml(aliased through Apache),
'mytileset' is section in a mapcache.xml file
3)The Seeding and the rendering needs other configuration of mapcache.xml
file(it is needs clarification).
4)The seeding may be through:
mapcache_seed -c mapcache.xml -t mytileset-g mygrid
or
during a certain map area is requested by client (it is needs clarification).
Thanks for any correction.
Best regards.

Re: [mapserver-users] Mapcache Question
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.

Re: [mapserver-users] Mapcache question.
only the wms and wmts services support dimensions (there is no spec
defining this support for the others).
you can either adapt your gmaps/js code to build a wmts url, or hack
into the mapcache code to add dimension support to the tms / gmaps
service.

Sounds like you do not have a validation_pattern for the data parameter.

mapcache itself does not do any pruning of the caches it has

expiration (i.e. memcache).
Mapcache can fit your need, provided:
- you configure your tileset with a "targetdate" -
you use
a memcache backend to store the created tiles, and set an
value in mapcache to 5 hours
If the memory requirement for storing 5 hours worth of tiles is too
important for a memcache server instance, you can have a look at
membase which will also store less frequently used data to disk. The
membase protocol is compatible with memcache, so you can use either
memcache or membase with the same mapcache configuration.
Of course, by running a script every hour to delete expired tiles as
you are doing now, you can then use the classic disk based cache
backend.

Re: [mapserver-users] Mapcache question.
Jerl,
mapcache itself does not do any pruning of the caches it has created,
but you can get the same effect by using a cache backend that supports
expiration (i.e. memcache).
Mapcache can fit your need, provided:
- you configure your tileset with a "targetdate" - you use
a memcache backend to store the created tiles, and set an
value in mapcache to 5 hours
If the memory requirement for storing 5 hours worth of tiles is too
important for a memcache server instance, you can have a look at
membase which will also store less frequently used data to disk. The
membase protocol is compatible with memcache, so you can use either
memcache or membase with the same mapcache configuration.
Of course, by running a script every hour to delete expired tiles as
you are doing now, you can then use the classic disk based cache
backend.

thomas

Re: [mapserver-users] Mapcache question.
Hi Jerl,
Maybe! is the short answer. The analysis of the problem is:
1. What is the primary purpose of mapcache?
Will it is a flexible tools that can do a lot of things, like on-the-fly
cache building, compositing images from tiles in the cache, etc. It's
primary purpose is to provide tile generation and tile serving for
environments that need tiles instead of draw on demand images.
2. So to some extent this depends on your usage model, ie: tile requests
per unit time.
3. it sounds like from your description below, that you are serving draw
on demand images and not using a tile cache at the moment.
To use a tile cache given your current scenario, you would still have to
do everything the same as before, but you would also have to figure out
what tiles at the various zoom levels needed to be removed when any of
the GeoTiffs changed, either replace some existing GeoTiff or got
removed because of age.
I'm not sure I see anyway that it will magically simplify your process.
And on the contrary, it will add some complexity to the whole process.
That said, if your demand is increasing and your server(s) are having
trouble keeping up with the image demand, then adding mapcache could be
a solution.

Hi:
I hope this is the proper place to ask questions about Mapcache since
it's been moved into the trunk of Mapserver.
I'm wondering if Mapcache can help with a particular setup, and if so
maybe some advice or direction on where to start?
Here's the setup. Every 5 minutes a new set of GeoTiffs are created in
a new directory. I create a tileindex for the GeoTiffs and use those in
the map layer. Every hour, anything more than 5hours old gets deleted.
I have a single mapfile setup.
The general layer is setup like:
LAYER
NAME 'IMG1'
METADATA
'wms_title' 'IMG 1'
'wms_srs' 'EPSG:4326'
'wms_extent' 'MINX MINY MAXX MAXY'
'default_targetdate' ''
'targetdate_validation_pattern' '^[0-9]{12}$'
END
STATUS ON
TILEINDEX '/PATH/TO/IMG/DIR/%targetdate%/TILEINDEX.shp'
TILEITEM 'Location'
TYPE RASTER
END
I'm currently loading these images as overlays for Googlemaps. using the
mode=tile&tilemode=gmaps...&targetdate=2011...etc.
Problem is it's too slow. I end up loading hundreds of images, as I
basically create an animation using sequential times.
I'd like to be able to have a single mapcache config file, that will
pass the date through to pull the proper shapefile, and have the result
cached so next time it's loading off the disk. MOST of the images end
up being blank/transparent tiles.
Is Mapcache a good choice for this?
The front end for this is just a simple GoogleMaps viewport, but ends up
loading multiple timeslots for display. It generates the request URL
(not currently in WMS fashion but could be).
Thanks for any help I can get.
