MAppFx Library

MAppFx is an interactive map environment that retrieves a graph of a site upon clicking on a map feature object–be it a point, polygon, or a line. WERI MAppFx is a product of WERI through the Guam Hydrologic Survey Program (P.L. 24-247) and USGS 104-b, available through the Guam Hydrologic Survey website. 

MAppFx is developed by the Guam Hydrologic Survey Information Management Team: Dannika Kate Valerio, Matt Wilson Zapata, Leroy F. Heitz, PhD, and Nathan C. Habana, PhD. The first two MAppFx products, Northern Guam Lens Aquifer: Production Well Nitrates and Southern Guam: Ugum Watershed – Streamflow Duration Curves, were done in collaboration with Brigham Young University’s Civil Engineering Department: Drs. Riley Hales, Gus Williams, and Norm Jones.
