[MapServer-users] WCS 2.0.1 GetCoverage request results in corrupted geotiff

Thu Sep 1 06:42:48 PDT 2022

Hi Jukka,

Thanks for your suggestion, in the end I managed to resolve the issue.

The corrupted geotiff was not produced by MapServer, but by a Bash script I wrote 🤦‍♂️ which I used to convert the multipart response from the WCS 2.0.1 GetCoverage request. It worked in the docker-compose setup presumably due to a different version of Bash compared with the docker setup in which the script was run on my local machine...

In any case we will not be needing the Bash script anymore to split the multipart response. Since I managed to solve the issue<https://github.com/MapServer/MapServer/issues/6551> that our MapServer setup is returning multipart responses for WCS 2.0.1 GetCoverage requests.

Cheers,
Anton

Hi,

Your question is exceptionally detailed but because the issue happens only with a certain Docker image maybe you should contact the authors of the image https://github.com/PDOK/mapserver-docker/. But you seem to be one of the contributors yourself https://github.com/PDOK/mapserver-docker/graphs/contributors. Generally speaking, if one Docker works while another one does not I think I would start by studying how they differ.

Aihe: [MapServer-users] WCS 2.0.1 GetCoverage request results in corrupted geotiff

Hi all,

I am running into a curious issue in which WCS 2.0.1 getcoverage requests produces a corrupted geotiff (which is bad) and WCS 1.0.0 getcoverage requests produce valid geotiffs (which is good). This behaviour occurs with our https://hub.docker.com/r/pdok/mapserver<https://eur06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fhub.docker.com%2Fr%2Fpdok%2Fmapserver&data=05%7C01%7Cjukka.rahkonen%40maanmittauslaitos.fi%7C8c5cd02a7bd44282578908da877fd14d%7Cc4f8a63255804a1c92371d5a571b71fa%7C0%7C0%7C637971280290882891%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=Q0s0yCgZuksu7M6TBPSUQ8uu8jKgKVw%2F0b17z4DXKKU%3D&reserved=0> Docker image. I could not reproduce the behaviour with https://hub.docker.com/r/camptocamp/mapserver/<https://eur06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fhub.docker.com%2Fr%2Fcamptocamp%2Fmapserver%2F&data=05%7C01%7Cjukka.rahkonen%40maanmittauslaitos.fi%7C8c5cd02a7bd44282578908da877fd14d%7Cc4f8a63255804a1c92371d5a571b71fa%7C0%7C0%7C637971280291039128%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=fWyRMTs5BbWDGVGFqS%2FnDUFTx2gZrP3qVW6%2BS2V9rSA%3D&reserved=0> Docker image.

On top of that; I can only reproduce this issue when running with docker. When running the same example with docker-compose it works fine.

I detailed the full issue description and steps to reproduce in this gist<https://eur06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgist.github.com%2Farbakker%2F889b10d839573c4cebb983ff19b17e94&data=05%7C01%7Cjukka.rahkonen%40maanmittauslaitos.fi%7C8c5cd02a7bd44282578908da877fd14d%7Cc4f8a63255804a1c92371d5a571b71fa%7C0%7C0%7C637971280291039128%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=U8TUOBs16nkC0D3ni7nkb53L5U3h0q2K4SoKu2rG7EM%3D&reserved=0>.  If anyone has any suggestions or ideas what might be causing it I would be grateful for a response.

Kind regards,
