I’ve created some glacier velocity maps in S1TBX and exported them as geotiff files so I can put them into Arc. However when I load the velocity into arc its in the wrong position. so I have two questions:
how can I get it into the right place?
is there a way I can overlay the velocity map over the slave imagery in SNAP itself?
So I tried Range Doppler Terrain correction on the velocity output and got the error Java Heap Space. I’m using the same DEM as before (external as the preset DEMs don’t cover the site). As for the second part, I’ve tried that and it doesn’t work. Do I need to rerun all the steps? as I just loaded the velocity into snap and tried it and had nothing.
java heap space is memory related. How much RAM does your computer have?
“It doesn’t work” gives me little information to understand your problem.
Did the offset tracking module produce a valid result (before the terrain correction)?
To be able to load two rasters at once with the Layer Manager, you need to have both of them within one product. As far as I remember, this is the case for offset tracking.
if the backscatter intensity is no longer in the product (I might have mistaken that) with the velocity, you can use the collocate module to bring both together. Then you can combine them in the Layer Manager
