Safe Drinking Water Information System Viewer

The Hawaii State Environmental Health Administration (EHA) contracted Windsor Solutions (Windsor) to design and implement a custom Safe Drinking Water Information System (SDWIS) viewer application for the Safe Drinking Water Branch.  The application gives users the ability to query drinking water system, facility and sample point data and return results in a spatially enabled and/or tabular format.  The viewer provides county and environmental health specialists the ability to access and use the state's information, and it also provides field users with a way to improve GPS-collected coordinate data and import it into SDWIS/State.

The SDWIS Viewer is a moderately complex system comprised of Web applications, Web services and mobile applications.  The GIS technologies used for the application include the GoogleMaps API and the ArcGIS Extension for the GoogleMaps API  for the Web interface, and the Windows Mobile SDK for the handheld GPS application.

The mobile application was designed to make the process of improving location data as simple as possible.  When field users use the one-click synchronize feature, it verifies whether or not it needs an updated catalog of sampling point sites that must be collected and automatically downloads it if necessary.  Field users can then collect and tag coordinates to a sampling point site in two clicks.  New sampling points can also be collected and added to the catalog.  If the GPS readings are not within acceptable tolerances, there are mechanisms to allow for post-processing the collected and uploaded coordinates.
