-- Visual Data Analytics (VDA) Geographic Information System (GIS) -- Using VDA Desktop GIS via Remote Desktop Service -- accessing the Federal GeoStatistical System .. and much more The Visual Data Analytics (VDA) Geographic Information System (GIS) is a collection of GIS tools and datasets. VDA GIS tools started with development of the VDA Web GIS. VDA GIS tools may now be accessed used in many computer environments. VDA GIS Remote Desktop Service The VDA GIS Remote Desktop Service (VDA RDS) enables the user to run the VDA Desktop GIS from the VDA RDS server. This is enabled through remote desktop operation available for most operating systems and platforms, including hand-held computing devices. Microsoft and Apple each have a product called "Remote Desktop." Patterns of Population Change by Congressional District The following view shows patterns of population change by congressional district. This is an illustrative view of how you can use the VDA GIS Remote Desktop Service.  About this Section & VDA GIS Framework .. goto top This document provides an overview of the using the VDA Desktop GIS via the VDA GIS Remote Desktop Service. VDA GIS resources have been developed and are maintained by Warren Glimpse/ProximityOne/Alexandria, VA USA and Takashi Hamilton/Tsukasa/Osaka, Japan.
