Geoprocessing Tools GP tools enable the development of workflows as models or scripts Extendable – You can create your own workflows Leverage low-level tools to create new tools

Sample Application – Well Permitting Calibrated AHGW MODFLOW model(s) archived on ArcGIS server Applicant uses web form to apply for new well Well data (coordinates, pumping rate, etc.) are sent to server GP tool locates model, adds well, exports MODFLOW files MODFLOW solution is computed, imported to database on server Results are compiled into a report and ed to review staff Custom series of GP tools are executed to determine impact of well
