The Center for Spatial Analysis developed and implemented a workflow management system for OBWEO based on state of the art GIS technology. All data flow is accomplished, monitored, and mapped through a web interface that reflects each user's needs. Data are gathered using a variety of methods including custom handheld computer applications, handheld and airborne GPS receivers, web entry, and upload from ArcView GIS. System implements complex automated routines to determine which cotton fields need to be sprayed, notify responsible parties, track spray events, and map the results. Users were trained and continue to be supported by Geo Information Systems staff. System went from design to implementation in less than 60 days and has been in use daily for over 2 years. Prior to this system's implementation, data were several months old. Today, system data is current and live everyday.

The Center for Spatial Analysis developed Internet search and retrieval system for OBS' "Oklahoma Rare or Endangered Species Dataset". Registered users have the ability to perform multi-field tabular and spatial queries against the database through the web interface and can then map the results. Special consideration was required when mapping results per federal requirements that certain data locations be "masked." An extension was developed for ArcView that would allow OBS staff to mask the data locations in a random fashion.

The Center for Spatial Analysis provides contract GIS services in support of OSEB activities. Staff coordinates with individual county election boards to geo-reference the voter registration system. This effort facilitated the identification of school and vo-tech election districts as related to precinct boundaries, and was then leveraged to support the re-precincting component of statewide redistricting. This effort was based on aforementioned GIS layers as well as 2000 Census results, Oklahoma State Senate boundaries, and Oklahoma House of Representative boundaries. Mapping of resultant precincts and the interface with legacy computer systems and applications such as the Oklahoma Election Management System provides OSEB with an all-encompassing GIS solution.

In 2000, the Oklahoma Legislature authorized the Oklahoma Tax Commission to develop and maintain a centralized digital mapping system for all Oklahoma municipal boundaries. The Oklahoma Tax Commission has worked with municipalities and the University of Oklahoma's Center for Spatial Analysis to develop this mapping system which provides the foundation for the Sales and Use Tax Rate Data System.

To Date over 180 municipal boundary changes have been updated and loaded to the Oklahoma Tax Commission's Sales and Use Tax Rate Locator Data System. These boundary changes affect your tax rate and can be searched by address, zip code and city name on the Oklahoma Tax Commission's site.

The Center for Spatial Analysis developed and maintains GIS layers of school and vo-tech district boundaries for all Oklahoma counties. CSA coordinates with officials at all agencies to maintain GIS layers, and provides public downloads of GIS layers through the CSA web site.

The Center for Spatial Analysis developed, implemented and trained the Osage Nation staff in use of a GIS system adding spatial analysis and mapping functionality to their existing data management system (RBDMS). The system was designed to meet specific staff needs identified through user analysis. Osage staff now has the ability to convert freely from any ESRI compatible source to their pre-existing RBDMS system, thus leveraging the strong points of both systems.

This project utilized multiple historic maps and documents to better demarcate the territory of the Muscogee Creek Nation in Oklahoma to derive an accurate representation of the nation's boundary in GIS. As with many tribal nations, boundary identification is essential to the Muscogee Creek Nation sovereignty and, consequently, services to their citizens.

In a cooperative agreement with the Oklahoma Fisheries Research Laboratory CSA will extend use of a recently developed enterprise GIS web site to benefit sport fisherman in the State of Oklahoma and facilitate lake record fish documentation by regional biologists.
