This is kind of similar approach that I am looking for. I have many pairs (2000+) of orthophotos from years 2011 and 2014. They are stored in 2 separate folders. I would also like to find differences between them, but first of all I need to reclassify only one band from orthophoto; orthophotos are composited of red, green and blue band. I need to reclassify only blue band in 2 classes, then subtract them and export result as polygon.
Orthophotos that overlapping each other have same name, except the 8th character is different.
I am attaching picture of model builder process for one set of orthophoto. Orthophotos with name E063462.tif and E063462A.tif are overlapping each other.
- I need to import/load only blue band from orthophotos that have first 7 characters the same.
- Then blue bands should be reclassified into 2 classes (threshold values is 130).
- The reclassified raster should be subtracted (newer minus older).
- The result should be exported as polygons.
I am not familiar with python so I need help to write a code to automate this process with 2000+ orthophoto pairs.
