High Resolution Elevation Data Ready to Use in the Red River Basin
By Chuck Fritz, International Water Institute

The Red River Basin Mapping Initiative (RRBMI) project is now complete and the high resolution elevation data (developed from LiDAR) is ready to use. The project began in 2008 with a goal of developing a high resolution digital elevation model (DEM) for the Red River of the North Basin south of the U.S./Canada border using Light Detection and Ranging (LiDAR). The $5.0 million project included 15 local, state, and federal funding partners.  More information on the project can be found at http://www.internationalwaterinstitute.org/lidar.htm

As part of the RRBMI project, the International Water Institute (IWI) also contracted with Houston Engineering, Inc. to develop two interactive mapping applications:

IWI LiDAR Download Portal: This application is designed to allow users to quickly find a location and download available LiDAR data products. The products available for download include: Raw LAS, Bare Earth LAS, 2-foot contours, 1-meter DEM, 3-meter DEM and hybrid intensity images.  More information on the data formats can be found on the website. Users are able to download up to 100 tiles at a time.  The application is currently serving over 4 terabytes of LiDAR data.

IWI LiDAR Viewer: This application is designed to allow users to view, search and print elevation data. The current application ingests 2-foot, 10-foot, and 50-foot contour and shaded relief map services published by the Minnesota Department of Natural Resources. It allows users to create graphic markups and print to pdf, as well as save and email graphic markups.  The web mapping applications were developed with Esri ArcGIS Server and Esri’s FLEX web mapping API.

Both applications are now ready for public use and can be accessed at  http://gis.rrbdin.org/lidarapps.htm

Currently IWI is planning on adding functionality such as “Label Elevation” and “Generate Profile” tools. There are also plans to add additional GIS layers such as historic flood extents and aerial photos.
