First some background. I am trying to create a GIS index coverage of
existing data. Because of the number of datasets, I need to automate the
process. I have successfully processed all the line data by creating
shapefiles of the flight lines and then buffering them to produce polygons.
I am now working on grids. The solution outlined by Ian below works great
interactively, but I need to script it to process several hundred grids.
When I record a script, the copy and paste actions do not appear. Are these
available?
