I'm fairly new to GIS and GDAL. But I need to solve the problem with anti-meridian. I have satellite images from Meteor-M2 that can span over -180 / 180 longitude.
I created .vrt file with correct GCP and running gdalwarp using the command below:
gdalwarp -tps -overwrite -t_srs epsg:3857 -of GTIFF 2022_12_20_06_26_30.vrt 2022_12_20_06_26_30.tiff
GCPs are in the EPSG:4326. I'm trying to project it to the mercator - epsg:3857. But every time I do it QGIS is showing messed up thing:
There was suggestion here and here. But they either do not work or require creating 2 different images.
I have several questions:
- Is it possible to create (find?) such projection based on longlat that won't suffer from anti-meridian issue?
- Why QGIS and GDAL can't handle such common thing? Is it something fundamentally geo-specific or tools simply doesn't support that?
Part of .vrt file:
