Thanks for taking the time to check my files. As you suggested I will surely try to get a updated version of map editor and see.

Thanks for your prompt reply and excuse me for late reply. My version of QGIS is 3.36.0-Maidenhead and MapEditor version is 12.3.1.54 Below are the intermediate files.

Hi Rogier, Thanks a lot for making this plugin available opensource. I encountered few issue when I tried to create roughness map files for an area in Tanzania with center coordinates ( -5.12238, 33.20613). After creating the bounding box and when downloading GWA landcover polygons. I saw below error in the box. https://drive.google.com/file/d/1y4eR_VEjIznPrXyGhDuB9K_MU40Hb6L3/view?usp=sharing My main concern is not that. Main concern is that the final WAsP roughness lines .map file when loaded into Map Editor gave me below errors. https://drive.google.com/file/d/16hfQwQrHMdbsoJglKkuOfz5AteE1QZgJ/view?usp=sharing https://drive.google.com/file/d/16r0AXqQUixh-1zSoUqkqyE-9kxe4-yJa/view?usp=sharing https://drive.google.com/file/d/1wqEWg5hVdjyN1EqY4sccbIjxdM_rBUed/view?usp=sharing When I view the roughness lines map it shows vertical lines as below. https://drive.google.com/file/d/1IXe5SxdiOy55u0R64-oO0_tPfjmFq1Xq/view?usp=sharing Looking forward to get this issue sorted with your help.

Hello Alexandre, Thanks for introducing me to Lib Interpolator. I have 289 wind atlases to add to get the interpolated wind atlas for the whole area. 289 Wind atlases cover the whole area on interest so there is no interpolation happening basically adding them together to get one wind atlas.

I have with me Wind Atlases covering 2km area. Since the area I am examining is larger and to get one wind atlas covering whole area I have to combine these individual wind atlases to one. These are the points. Each point is a square 2km x 2km wind atlas. In the background is my area of interest. Now the challenge is to combine all these wind atlases covering the area of interest into one wind atlas.
