NITF Extension for ArcGIS - Performing a Spatial Subset of an Image




1. What is the most efficient way to go about setting the size of my spatial subset AOI ?

     I.e . Where in ArcGIS can i get the line and sample values to display so that i can input them into the box to subset it ?




1. Draw an extent box with the graphic tool from the Drawing toolbar. 


2. Export that AOI as an NITF subset such that it preserves the RPC info inside the ICHIPB tag.

The problem is the interface only allows you to specify your extents in terms of line and sample values.


I tried going to Data Frame > General tab > Units but there is nothing there
