QA/QC for Arc Hydro Terrain Preprocessing Vector Data: The Arc Hydro health check using Data Reviewer

The Arc Hydro team has developed a data health check process that uses the ArcGIS Data Reviewer extension to assess and diagnose the quality of water resources data. The ArcGIS Data Reviewer extension is a set of functions and processes that checks the health of vector data. It finds hidden abnormalities before they can create problems for processing and analysis tasks. You can add the healthy vector data to the integrated data infrastructure to render proper connectivity for water resource analysis such as correctly routing the water through a drainage system. Then, you can also impose the known drainage patterns into the raster modeling infrastructure. Arc Hydro tools and ArcGIS Data Reviewer ensure that vector and terrain data work together within and across layers of streams, lakes, and sinks.

The Arc Hydro data health check streamlines quality control.

Software requirements for the Arc Hydro data health check are ArcGIS 10.1 or higher, the ArcGIS Data Reviewer extension, and Arc Hydro tools (version 10.1.0.176 or higher for ArcGIS 10.1 and 10.2.0.10 or higher for ArcGIS 10.2).

Read the Arc Hydro Tools Process Paper #1, which includes step-by-step instructions for using the Arc Hydro health check along with an example application of the tools. This paper and other Arc Hydro Resources can be found on the Hydrology Resource Center Education Gallery.
