I want to clip out 500 - 1000 cut-outs of 500px*500px of an image (a city area) (.tiff) and a shapefile layer above it (.json or .csv). These files are big for a manual process as I have to select the area manually and clip it. Is there any way this can be automated to cut the image into chunks of 500x500 pixels?
I can propose how to clip part of the source image by 512*512 (or whatever size) tiles
- Create AOI by which you clip source image
- Perform Raster Extraction Clipper (Qgis 3.2)
- Using plugin Qtiles (available in Qgis 2.18) perform extracting tiles 512*512 into some directory
- Then you have a lot of tile divided into several subdirectories respective to zoom level
