I've changed from an academic institution where ArcGIS was a relatively trivial price to a non-profit where we're faced with the full price. I'm trying to figure out exactly which version I need to purchase, and though I've looked through the lengthy product matrix PDF (http://www.esri.com/~/media/Files/Pdfs/library/brochures/pdfs/arcgis1021-desktop-functionality-matrix.pdf), it only helps so far as I know the exact terminology of what I do. I'm going to list what I do and hopefully you can tell me what version I need. I think it's pretty basic, but you never know ...
- Create new project files (I know basic does this).
- Create arbitrary map projections (e.g., custom parameters for a moon of Uranus).
- Create shapefiles with my arbitrary projection.
- Add different fields to the shapefiles.
- Basic map display of shapefiles, vector and raster data.
- Georeference images to my map (I know basic does this).
- Use Streaming when Editing shapefiles to create custom polylines and polygons.
- Basic map display customization (e.g., color ramp of raster data, adding legend and scale and N arrow in Layout view).
- Able to export* the vertex points of shapefile polylines and polygons as a simple ASCII text file for use in other software.
*I use this feature all the time and is why when version 10 of ArcGIS came out, I couldn't use it, and have stuck with 9.3.1. This feature was in ArcCatalog > ArcToolbox > Samples > Data Management > Features > Write Features to Text File ... . I don't know if 10.3 has this capability because, as I said, I've stuck with 9.3 since I was unable to find this in 10.
Anyway, those are really all that I use ArcGIS for. No advanced spatial analysis or fancy things like that. Really just basic display, basic editing, basic export. Is this something I could get away with a Basic license for?
