Issue with the hostname

[denis-f]

Dear developpers,

Many thanks for this tool, which we used successfully some time ago. I try now to re-use it and it seems that there is a problem with the host wxs.ign.fr, probably due to the recent server changes at IGN :

urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='wxs.ign.fr', port=443): Max retries exceeded with url: /search/layers?&cql_filter=demat_layer_id+=+'DEMAT.PVA$GEOPORTAIL:DEMAT;PHOTOS'+and+INTERSECTS(the_geom,POLYGON((43.65+3.5,43.65+3.6,43.75+3.6,43.75+3.5,43.65+3.5)))&outputFormat=json&request=GetFeature&resultType=hits&typeName=ign:missions&version=1.1.0 (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x793e469348d0>: Failed to establish a new connection: [Errno -5] No address associated with hostname'))

How can I get this script work again ?

Many thanks in advance.

Hi,

You're right, this repository should have been archived. This small script was working with the previous version of IGNF spatial data infrastructure. The situation has changed : the KML files have been superseded by vector tiles, the URLs of download services have changed, ... . I'll have a look and see if I can manage something in the coming weeks.

However, in order to give the best answer to your need :

• Would it be satisfactory if https://remonterletemps.ign.fr/ was giving the mean to download a full aerial survey (list of urls, archive, ...) ?
• If not, please feel free to give more details about your use case

Cheers

Many thanks for the quick answer !

What I appreciated in the tool was that it allowed to possibly download the full archive covering a given area. Moreover I would appreciate a tool that would give access to the latest data. On https://remonterletemps.ign.fr/ the latest available images seem to be the ones of 2011. Images in geoportail are from 2021 and I guess that there may be even newer images available.

Cheers

Hi,
any news about the request by @denis-f ?

Thank you

Hi there,

I'm trying to see what can be done directly at service level inside my organization before doing another hacky script. @frazucca are you also interested in the ability to download images on a given area (bounding box) ? I'm also interested in your use cases that involves the images from remonterletemps :)

I should have a better view of what can be achieved by mid february

Cheers

Hi @esgn
I was too short before. Yes I'm really interested by managing downloading images inside the RLT collection.
In the past I was happy with pva-ign, so something similar is ok. Ideally, at least for me, it's the possibility to do something (search and download) in QGIS. But of course a python macro it's more simple to do.

In the meanwhile, since the time troubles start (migration from wxs.ign.fr, right??) I recovered a vectorial (geojson) from https://github.com/cquest/photos-aeriennes-ign/tree/master?tab=readme-ov-file import into geopackages and then I extract, from processing bbox and missions footprint, the code and name of img, with just one problem using the 1941 data.

Thank you
All the best
franz

Hi @frazucca and @denis-f,

For another project, Pompei (https://github.com/IGNF/Pompei), there are scripts to download images from the new version of RLT.
There are 3 steps.

Download footprints et metadata about missions :

python scripts/get_data.py --outdir footprints

For one mission, get the footprints of images :

python scripts/get_flight_plan.py --footprints_file fichier_emprises --id id_chantier --outdir outdir

Download images :

python scripts/get_images.py --selection selection --id id_chantier --epsg epsg --outdir outdir

I think it is useless to install docker for this use case. You need only the conda environment (with pompei/environment.yml).

Downloading images is less automatic than with this repository but I hope it will be useful for you.
