GIS Tools

• A useful Avenue script for ArcView 3.x: link_ext.ave is a script that Andy put together that allows you to set up hotlinks to any document type that is registered with MS windows ... CAD files, word docs, etc. Also works with web URLs.
• Another Avenue script: view_calcareas.ave is a script that calculates area, perimeter, acres, and square miles for polygons in a theme. It has more error checking and other friendly features than the one that comes as a sample with ArcView 3.2.
• Coming soon: a couple of newer things. As part of a project we were doing with the watershed management team at Stony Brook, we needed to be able to group the records in a GIS layer into quantiles (groups with the same number of members in each group). ArcMap and ArcView 3.x both allow you to do this in the symbology of the map, but we needed to be able to calculate the values into the attribute table permanently. So we wrote a tool that does that. Another tool simplifies the process of adding aerial photos from the 2002 overflight into ArcMap. They both work, but we need to add some error-checking and documentation and stuff, and then we will put them up here.
