We are building mosaic datasets for 100's of rasters (Topo sheets). Used QGIS Tile_Index to get the raster_topo_sheet's extent as vector. But the issue is, overlaps near the edges of all the topo sheets. Instead of manually correcting these edges for footprint creation, can't we merge/delete one boundary and make it seamless ?
1) Tried "Eliminate selected polygons" in qgis with alternate polygons selected (Largest common boundary). But result was not as expected.
2) Tried "Dissolve tool" in QGIS. Removing overlapping/duplicate polygons in same layer using QGIS?. But same overlap exists.
