Image tiles are not rendered completely

Open Brakebein opened this issue 3 years ago • 1 comments

Describe the bug When generating a 3D model, the texture contains a lot of black areas. However, this issue doesn't occur with satellite imagery (MapBox-Satellite, Esri.WorldImagery), but with all the non-satellite imagery providers, e.g. ThunderForest-Outdoors, MapBox-Streets, Stamen-Toner, etc. It seems that the downloaded image tiles are not processed correctly. I tested it for different regions and with low, medium, and high image quality settings.

To Reproduce Steps to reproduce the behavior:

  1. Go to https://elevationapi.com/playground_3dbbox
  2. Select an area
  3. For Imagery Provider, select "ThunderForest-Outdoors" or any other non-satellite imagery provider
  4. Click on 'Generate 3D model'
  5. See texture of generated 3D model

Expected behavior A rendered texture without black areas.

Desktop (please complete the following information):

  • OS: Windows 10
  • Browser: Chrome 104, Firefox 103

Additional context When choosing some imagery providers, e.g. "MapBox-Outdoors", error code Response status code does not indicate success: 410 (Gone). gets returned.

Hi @Brakebein sorry for the late reply. I think it's an issue about multithreading still done in a poor way. I will have a look.
