So from the csv above, convert each row to geo-referenced shp. Clip into smaller sections. Convert back to positions based on a determined (0,0) point.

| Mar 8, 2021 at 16:18 | comment | added | Binx | In QGIS I create a fishnet (lets say of 100x100ft). For simplicity sake lets say the csv above gets clipped into 5 polygons that contain 4 polygons each (20 polygons total). I need to take each of the polygons and turn their geo-extent-coordinates back into xmin, ymin, xmax, ymax based on a predetermined (0,0). Lets say the bottom left corner of the polygon that holds the smaller ones. | |

Each row in the csv contains the extent of one polygon. So in this picture I would have 20 polygons for 0.tif. For another tif file I could have 3 polygons. So on and so forth. Based on the tifs properties such as projection, the xmin, ymin, xmax, ymax coordinates are being converted into geocoordinates. So that I can properly view them in QGIS.
