Problems with projections and extraction..

Discussion created by kateallberry on Mar 10, 2011
Hi,

I'm trying to format layers for use in the spatial distribution programme MaxEnt; as my difficulties are GIS-related, this seemed a good place to start. (I'm using ArcGIS 9.3 and not too good with scripts).

1) I need to project my occurance (point) data and extract new lat \ long coordinates. I have successfully re-projected the file to a shp. file, but the coordinates remain as the last CS. How can I extract these?

2) Every raster layer needs to be in the same PCS \ extent and my main points (occurrance) layer also has to be in the same CS. I have tried projecting my raster, re-projecting all layers, projecting to another extent using a pre-existing polyline \ polygon of the same area, clipping to the polygon to the correct extent.. All no luck.

Thanks loads for any help!
Kate
