[mapserver-users] No Layers when configuring TinyOWS with a Mapserver (.map) File

[Balajee R.C]

Am trying to expose a vector layer (loaded from shape file into PostGIS) as
a WFS layer using tinyows.

Following the instructions in the mapserver/tinyows documentation, here is
the .map file I have come up with so far:

MAP
NAME "world"
CONFIG "MS_ERRORFILE"
"/home/balajeerc/Projects/Build_Dir/myproject/data/logs/mapservice_errors.log"
EXTENT -180.000 -90.000 180.000 90.000

WEB

END

END

This .map file works fine with mapserver, i.e. I am able to render the
feature layer as a WMS service using QGIS as a client.

However, the WFS service (served by tinyows) using the same file (set using
`TINYOWS_MAPFILE` environment variable seems to show no layers in
GetCapabilities (and hence QGIS is not able to load any).

The output from `tinyows --check` is as follows:

balajeerc@Balajee:~/Projects/tinyows-1.1.1$ ./tinyows --check
TinyOWS version:   1.1.0
FCGI support:  Yes
Config File Path:
/home/balajeerc/Projects/Build_Dir/myproject/data/service_data/data/wfs/world.map
(Mapfile)
PostGIS Version:   2.1.8
PostGIS dsn:   host=localhost user=mygis password=asdf123
dbname=mygis port=19095
Output Encoding:   UTF-8
Database Encoding: UTF8
Schema dir:
/home/balajeerc/Projects/Build_Dir/myproject/deps/mygis-services-0.1/data/schema
Display bbox:  Yes
Estimated extent:  No
Check schema:  Yes
Check valid geoms: Yes
Available layers:
balajeerc@Balajee:~/Projects/tinyows-1.1.1$

Note that even though I am using a 1.1.1 version of tinyows, it prints
tinyows version as 1.1.0. Also note that it prints no layers.

Wondering what is going wrong, I decided to step into the code. I
recompiled code after turning off (`-O2`) optimizations and with debugging
(`-g`) enabled.

I am only able to get so far as the `ows_parse_config` method in
`src/ows/ows_config.c`. I am, for some reason not able to step into
`ows_parse_config_map` in `src/mapfile/mapfile.c`. This probably has
something to do with the fact that `mapfile.c` is generated by flex using
`src/map/mapfile.l`.

At this point I am completely stuck and at a brick wall as to what might be
going wrong. Can someone here please help?

TinyOWS version: 1.1.1 (Release
)

[mapserver-users] Mapcache - optimum format for orthophotos?

[Robert Sanson]

Hi

What is the recommended format for serving and storing true colour orthophotos 
via Mapcache if we wish to preserve maximum detail? The source data are 
uncompressed GeoTiffs served as WMS by Mapserver.

Many thanks,

Robert Sanson

[mapserver-users] Mapcache - how to deal with changes to mapcache.xml?

[Robert Sanson]

What is the recommended approach to dealing with stored tiles when changes to 
mapcache.xml are made, such as a change in the set of resolutions in a grid? 
Should we disable the Web server, delete all the existing tiles then restart 
the server?

Many thanks,

Robert Sanson
