Info

After the models are installed and you have copied the pilot models in theirrespective locations make sure they run in stand-alone mode successfully.3.4 Registering the DLLsRegister ALL of the DLLs in MapToMap\DLLs. Be aware that the third partyDLL (heclib50.dll) is a non-registrable DLL that has to be placed under the“system32” directory location. One simple way to register DLLs is to run theRegister_in_menu.reg file. Search for the Register_in_menu.reg file normallylocated in “C:\Program Files\ArcGIS\DeveloperKit\tools” and double click on it.By doing this, the mouse right click allows you to automatically register andunregister dlls for ArcGIS. The needed DLLs are shown below3.5 Registering File Extensions in ArcGISIn order to work in ModelBuilder you need to make all the needed file extensionsknown to ArcGIS so they can be referenced. In ArcCatalog, add the following fileextensions that might be unknown to ModelBuilder: .dss, .sdf, and .prj (this onemight be ambiguous as it is used as a HEC-RAS project file and also as a GISprojection file) file types by using the menus: ToolOptionsFile Types.3.6 Checking Accessibility and License Availability in ArcGIS• Make sure HEC-HMS and HEC-RAS programs are NOT open• Make sure the Spatial Analyst extension is turned on• Make sure the 3D Analyst extension is turned on (for TIN manipulation)204
3.7 Map2Map UsageAll of the model builder tools are in the MapToMap toolbox, located in theMapToMap folder. By using ArcCatalog you can access this toolbox which inturn contains the following toolsets:• TSTransfer - contains tools for transferring time series data from oneformat or feature class to another• ModelCaller - contains tools for calling HEC-HMS and HEC-RAS.• GeoRAS - contains tools which mimic the functionality provided by theGeoRAS toolbar for ArcMap related to GIS post-processing of hydraulicinput to generate the flood inundation map.• Map To Map model – Main model for converting rainfall data to a floodinundation polygon.In ArcCatalog look for the Map2Map Model you want to execute from the currentavailable versions, that is: Map2MapLocal (running from precipitation inputlocally stored), Map2MapFTP (running from precipitation input located at remoteFTP server), Map2Map_ArcView (same as Map2MapLocal but for those withjust ArcView license, and Map2MapDesign (running from statistical designstorms for Texas).In ArcCatalog right click on the Model you want to execute to open the model’sworkflow for it.205
