I’ve got some hyperspectral satellite imagery that is off by 30-100m, which I can tell by the location of roads compared to Open Street Map.
I’d like to use the interactive capabilities of HoloViz to allow interactive creation of Ground Control Points (GCPs) that will then allow georeferencing via a tool like gdalwarp.
I’m basically planning on following the workflow here: Mastering GDAL Tools (Full Course Material)
I want to create a dataframe like:
pixel (column) line (row) X (Lon) Y (Lat) 418 893 70.5 15.23 380 2432 70.12 5.24 3453 2434 90.43 5.74 3407 895 90.34 15.23 2662 911 85.22 15.25
I know I can return the lon,lat values of points clicked on using HoloViz, but how can I also return the pixel values?
