Here's a wealth of ArcView info from Gary Greenburg, sample scripts and this handy description of ESRI sample scripts that come bundled with ArcView. Also, I have to try this Mapbook sometime - a utility for large volume plotting.

XTools from the ODF. Xtools is a user-developed extension aimed at meeting the analytic needs of ArcView users in the Oregon Department of Forestry. It is being made available to others with similar needs free of charge on an "as is" basis. Click here for download instructions.

Maps On Demand, users define keyplans to print individual keyplan maps at a desired scale (An Excel spreadsheet is provided to assist in keyplan design.).  Keyplans can be quickly developed in a couple of minutes using Maps On Demand's set-up tools. Once the keyplan is developed, user's can print off the entire keyplan map set, a group of maps, or individual maps with a mouse click. Click here for examples of maps they produced using Maps on Demand.

During FY97 DASC produced over 30 interactive maps, each containing various themes, on the WWW. As part of the contract deliverables, the image map development methodology must be published on the DASC WWW site. The following are the steps DASC formulated to make these custom image maps.

Christopher Eykamp has developed a Virtual GIS prototype combining ArcView data with HTML and Java in order to demonstrate how basic GIS functionality can be provided over low-bandwidth Internet connections. This is nice - I'd like to see more of what he does!
