I have a database (x,y,z) covering some area and
I need to separate some part of the database
corresponding to a region inside of this
area. I have the limits (xmin, ymin, xmax, ymax).
How can I make a database for this region?
I did a grid whit this limits but not an
another database with this data.
Thank you,
