Hello everyone,
I am attempting to do offset tracking between two different dates. I have successfully been able to assign a master and a slave image in my code, but I am unable to coregister the two images. Please see my code below:
print “Initiating DEM Assisted Corregistration”
print “Reading products to coregister…”
parameters = HashMap()
CoregistrationOp
parameters.put(‘SMaster’, target_0_0)
parameters.put(‘SSlave’, target_0_1)
CoReg = OrbFile_master + “_CoReg”
target_1_0 = GPF.createProduct(“CoregistrationOP”, parameters, target_0_0)
ProductIO.writeProduct(target_1_0, Coreg, ‘BEAM-DIMAP’)
The error is being initiated at the GPF.createProduct line. The error I am getting is:
RuntimeError: java.lang.NullPointerException
Can anyone help me figure out where I am going wrong? The images are currently not stacked when starting the process, do you think this is the issue?
Thanks!
