Harris County's Benchmark Network Evolves Into Web-Based GIS Mapping Solution
Track: Surveying
Author(s): William Meyer, Elle Anderson, Brandon Grimm, Todd Buehlman

Harris County established a benchmark control network containing over 1,500 monuments for the updated Flood Insurance Study. This system was spatially designed in ArcGIS 8.3, and various layers of information were developed in association with this network to be used as support in the future. This information was delivered to the community via a user friendly web-site with GIS mapping capabilities that allowed the user to search for a monument by street address, proximity, monument ID, coordinate location, map grid number, or even select by region. This innovation was built on an ArcIMS platform with custom JavaScript ArcXML and ASP .Net code for the navigation and search utilities. Several other data layers including monument photos and sketches are also available for download. This site was set up to be easily maintained with a database that can be updated resulting in the auto-generation of revised HTML pages.
