What is an Isohyetal? An isohyetal (or isohyet) is a line joining points of equal precipitation on a map. Texas and Western Louisiana, July 24-27, 1979,

FlowWorks.com Isohyetal maps, also known as contour maps, are a method of showing values spread over a geographic area. Another example would be how contour lines are used to show elevation changes in topographical maps. For our app, we are using contour lines to illustrate rainfall over a city or region. The gradient from red to blue shows areas of greater to lesser rainfall, based on a user-defined period.

FlowWorks.com The Technology Behind the Tool The app uses custom built Esri ArcGIS Server Geoprocessing Tools to create both the rainfall surface and rainfall contours. This allows non-GIS users to develop and create custom maps for reporting, as well as aiding in more timely decision making.
