Downloading from WMS Geoportail.fr server

falqn · March 2010

Hi,
I have problems with downloading data from French geoportail.fr server http://wxs.ign.fr/geoportail/wmsc - list of layers appear but GM can not download any portion of data...
When I try with http://wxs.ign.fr/geoportail/wms it's working with one available layer - imagery. Is WMS-C service available in GM? What is the difference between WMS and WMS-C?
more info www.geoportail.fr and https://api.ign.fr/geoportail/api/doc/index.html

Best regards
Wojtek, Poland

Wojtek,

I just tried and am getting an error return of 403 from the server, which means that access is forbidden. Is this server perhaps locked down so that your IP address has to be approved by them before they will server up the data?

Thanks,

Mike

The 2D API allows you to create maps by getting connected to Geoportal's services.
Geoportal's WMS-C, WMS, WFS services can be plugged to desktop GIS applications. One needs to develop a connector to our GeoRM implementation along with the above services connectors. For more information, please contact us at 'contact dot api at ign dot fr'.

A proof of concept of using Geoportal's 2D streams into 3D application has been to use Nasa World Wind

This application is based on the NASA World Wind Java Development Kit to allow Geoportal's layers overlaying in this virtual globe.
These Geoportal's layers are served by the WMS-C service as explained there.

Hi,

Some informations about Geoportail and WMS-C : https://api.ign.fr/geoportail/api/doc/developpeur/geodrm.html

Geoportail is a great data source for France... but impossible to import any data in GM at this time. Any solution in the future ?

global_mapper · January 2011

I'll take a look when I get a chance and see if it would be simple to add support for these layers in Global Mapper.

Thanks,

Hi,
There are news about the problem of this thread?
The http://wxs.ign.fr/geoportail/wms in my case don't work, list of layers appear but I can't download from FXX.ORTHOIMAGERY.ORTHOPHOTOS
Suggestions?

Best regards, Fritz Peter

Fritz,

Sorry I haven't had a chance to look at adding WMS-C support yet to know how much work it is.

Thanks,

Hi Mike,
thanks a lot for your reply. From my point of view, would be really important to add this feature to Globalmapper, that is a complete and wonderful software, perhaps the best in its kind.

Best regards. Fritz.

fritzpeter · September 2011

Hi Mike,
with the new version of Globalmapper the WMS-C support is been added?

Best regards. Fritz

global_mapper · September 2011

There isn't any support for WMS-C yet.

hello,

with the informations given at this url

http://api.ign.fr/geoportail/document.do?doc=qgis
and
https://api.ign.fr/geoportail/document.do?doc=6593220

"INSPIRE WMS" is working with Global Mappper, but it's slow, and there are less layers available.

"INSPIRE WMS-c" could work but the parameters "&WIDTH=512&HEIGHT=512" are always sent by Global Mapper with "&REQUEST=GetMap" so "&BBOX=" is always wrong because the server accepts only "&WIDTH=256&HEIGHT=256".

according to

GET http://wxs.ign.fr/inspire/wmsc?ServiceName=WMS&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetCapabilities

the <TileSet> parameter describe for each available layer this parameters :

<SRS>
<BoundingBox>
<Resolutions>
<Width>
<Height>
<Format>

but Global Mapper seems to not use all of them, especially <Width>, <Height> and <Format>

how to reproduce the errors :

create an account at
```
https://api.ign.fr/geoportail/myAccount.do
```
and get a "service de consultation INSPIRE" key

download in an unique directory, the GeoDRM wrapper, the configuration file and the batch file.

https://api.ign.fr/geoportail/api/doc/sources/geodrm-wrapper.jar
http://www.ign.fr/partage/api/tutoriel/wrapper-config-wmsc.xml
http://www.ign.fr/partage/api/tutoriel/qgis_proxy_geoportail.bat

edit "wrapper-config-wmsc.xml" and replace XXXXXXXXXXXXXXXXXXX with your API Key

for debugging purpose, i used Paros Proxy (free of charge man-in-the-middle proxy which captures all traffic between clients and servers)
```
http://www.parosproxy.org/
```
and updated the proxy section of "wrapper-config-wmsc.xml" with
```
  <proxy>
    <host>localhost</host>
    <port>8080</port>
  </proxy>
```
if debugging, launch "paros" then "qgis_proxy_geoportail.bat"
if not, "qgis_proxy_geoportail.bat" only from the console (if configuration errors) or with a double clic.
edit [drive:]\[installation_folder_of_Global Mapper]\epsg_codes.txt and add this lines at he bottom
```
//

310024802,Equirectangular,RGF-93,meters,CENTRAL MERIDIAN=0,TRUE SCALE LATITUDE=46.5,FALSE EASTING (m)=0,FALSE NORTHING (m)=0
```
there should be other EPSG code to be added, but this one is for France Metropolitan (FXX)
open Global Mapper
add a new WMS source
```
http://127.0.0.1:10001/wmsc
WMS
```
get the list of available layers and choose one tagged with (FXX)
an error message will popup at the end
if debugging, Paros will show all the requests and Responses
NB : with Paros / Tools / Manual Request Editor, you can build your own request
add a new WMS source
```
http://127.0.0.1:10002/wms
WMS
```
get the list of available layers and choose one tagged with FXX
images will be loaded in Global Mapper

it would be great if you could add support for "INSPIRE WMS_c" in Global Mapper.
with the GeoDRM wrapper, i think it's very close to the end, with your support of course

thank you for your attention,
Richard.

global_mapper · September 2011

Richard,

I will take another look and see if support for that particular source can easily be added.

Thanks,

global_mapper · September 2011

Richard,

It's not quite a simple matter of switching to use to use a tile size of 256. Global Mapper needs to read the <TileSet> tags and setup its tiling of the WMS data based on the tile layout described in that rather than using its own default access zoom levels and tile sizes. Not trivial but certainly not rocket science either. I'll see if I can take a look in the next week or so and make this happen.

Thanks,

Mike

Geo · September 2011

Mike,

you're right, WMS_c needs that all request have to be made with pre-defined parameters and ask for a pre-existing tile.
i've found a WMS Tiling Client Recommendation documentation here :

http://wiki.osgeo.org/wiki/WMS_Tiling_Client_Recommendation

there is also a small documentation in english on how to build a WMS-C request for the Geoportail.
see : API Geoportail / Documentation / Advanced WMS-C use

https://api.ign.fr/geoportail/api/doc/developpeur/wmsc.html

the full english Geoportail API Documentation is also available in PDF

https://api.ign.fr/geoportail/api/doc/GeoportalAPI.pdf

see chapter 17, Advanced WMS-C layers and the internal link for layer resolutions.

hope this help,
thanks for your support,
Richard.

hello,

i made a mistake in the epsg_codes.txt

//
//IGNF:GEOPORTAL
310024802,Equirectangular,RGF-93,meters,CENTRAL MERIDIAN=0,TRUE SCALE LATITUDE=46.5,FALSE EASTING (m)=0,FALSE NORTHING (m)=0

with this parameters, it produces a vertical shift and a horizontal shift.

i can't figure out the good parameters for the epsg code in Global Mapper.

test procedure :
i retrieved from the Geoportail wmsc server an area with pixel size=0.25m ; i used Gdal and a file called cad025.xml

I think the datum is probably the issue. Are you sure that it should be RGF-93?

hello Mike,

I checked again, but I'm certainly missing something.

except the naming of the projection,
Equirectangular (in Global Mapper epsg_codes.txt)
Equirectangular (in IGNF:GEOPORTALFXX)
Equidistant_Cylindrical (in Global Mapper prj file)

everything looks identical.
I don't understand why there is a shift when I load the same area in IGNF: GEOPORTALFXX and RGFCC49.

thank you for your attention,
Richard.

PS: i've uploaded the 2 files made with gdal (cad025.tiff and cad025cc49.tiff) to your ftp (folder IGNF:GEOPORTAL)

Richard,

I see one thing in the datum definition that is odd. The ellipsoid defined with the datum is an ellipsoid, but then in the projection parameters the semi-major and semi-minor axes of the ellipsoid are explicitly defined and both are the same, which looks like a sphere. This looks suspiciously like the situation with the Google Maps datum that looks like WGS84 but behaves slightly differently. Try changing the datum name in your EPSG code definition to 'GOOGLE MAPS (SPHERE RADIUS 6378137)' and see if it then lines up.

Let me know if I can be of further assistance.

Thanks,

Mike

Bravo !

this epsg_codes.txt works.

i tried to update epsg_codes.txt, the before last, IGNF:TERA50STEREO, isn't complete, i think a custom datum is needed.

i didn't already made any tests with the epsg custom codes.

can you tell me how to write the EPSG IGNF:TERA50STEREO for Global Mapper ?

thanks for your great support,
Richard.

global_mapper · September 2011

Richard,

Create a custom datum based on the International 1909/1924 ellipsoid with the following X, Y, and Z transformation parameters:

dx = 324.9120
dy = 153.2820
dz = 172.0260

That should give you what you need. Make the name you use for the datum match what is in your epsg_codes.txt file.

Thanks,

Mike

Hello,

With gdal_translate, it is rather complex to retrieve data from the GeoPortail or via an INSPIRE API key to show them in GlobalMapper.

IGN (Institut Géographique National) released a new version of IGNMap :

Thursday, October 20, 2011, by FBecirspahic wrote:

Consult INSPIRE data with IGNMap.
As part of the implementation of the INSPIRE directive, IGN provides the data flow. To access these feeds, you need to have a key, the latter being available free on the site api.ign.fr .

see full thread in french

http://ignmap.ign.fr/spip.php?article9

or in english via translator

http://translate.google.com/translate?sl=fr&tl=en&u=http://ignmap.ign.fr/spip.php/article9

I tried this new version, exporting layer "CADASTRALPARCELS.PARCELS (EPSG:310024802)" at different resolutions (1m and 0.50m) because all tiles are not available at all resolutions. WMS-C is more performant than WMS for this job.
Loading all images in GlobalMappper using EPSG code: 310024802 described above as native projection works fine.

It is currently the fastest way I found to use the Geoportail data with GlobalMappper.

global_mapper · October 2011

Note I am still working my way through my todo list to get back to WMS-C support, but it is not off my radar.

Thanks,

Geo · October 2011

hello Mike,

You said that adding WMS-C support is "Not trivial but certainly not rocket science either."
But it is often necessary to use several tools to achieve our goals.
So I quoted the Gdal and IGNMap software because they are free and allow to use the INSPIRE Geoportail data with GlobalMappper, not the direct way, but a rather simple workaround.

Of course, I'd rather do it directly with GlobalMappper and I thank you to make all changes and improvements that users are constantly asking for.

Hi,
Mike et Geo : I just want to thank you for this post, VERY usefull for me today.
Papaver.

Geo · April 2012

some changes are coming soon
see : Géoportail 2012 changes

automatic translation (bold and underline by me) :

Changes to affect how the application accesses the services.

The main developments in web services in the new version Geoportal are:
replacement for the standard flow of tiled WMS-C by the standard WMTS,

choice for flows tiled projection EPSG: 3857 and a pyramid OGC compliant (parameters identical to those of Google Maps)

the removal of the control system access token (GeoDRM), and the transition to a filtering method compatible with the GIS clients.

geocoding on land parcels in addition to place names and addresses.

Innovations will also be phased in after the opening:
the possibility of access in HTTPS

dissemination of data vector WFS,

flux vector curled (kml) and a 3D API,

a service of coordinate transformations,

a calculation service elevation.

From late March, will be issued a test platform services Geoportal three and documentation of new products.

global_mapper · April 2012

Actually some of those sounds encouraging to get it working with GM right now, particularly the tiled system with parameters identical to Google Maps. Sorry I keep delaying the tiled WMS implementation, seems my todo list is never ending!

Do you know if the switch-over to WMTS (standard tiled WMS) has been completed yet? We now have support for WMTS under the covers in Global Mapper and would like to add support for adding general WMTS sources to Global Mapper.

that's all the news.
i don't have an api key for this beta test.

glad to hear that you have support for WMTS !
i hope that the new GeoDRM will not be an insurmountable difficulty.

global_mapper · May 2012

I'm finishing up the generic WMTS support now, so it will be in the v14.0 release later this summer. There should be builds available to try this with by the time GeoPortal goes live with the WMTS support.
