Which way does it flow? An effort to map roadside ditches in Houston.
Track: Surveying
Authors: andrew hands, Garner Peterson

Open channels/ditches make up a critical component of the Houston storm drainage system. Being an area that is near sea level and relatively flat, survey grade GPS data collection with sub-inch accuracy was used to collect ditch profile transects and cross-street culvert information. A network of ditches and culverts was then generated and tied into the existing GIS for storm water network that will be used for hydrological modeling and assist in improving Houston's storm water assets.
