13 Execute Map2Map for New Study AreaUsing ArcCatalog or ArcMap execute Map2Map for your specific study area byfollowing the process described in section 3.7. The user may change the name ofthe output floodplain map by right clicking on the final green oval representingthe output flood map and changing its name as shown in the figure below. If youuse ArcMap to execute Map2Map make sure the Arc Hydro dataset beingreferenced corresponds to your geodatabase inside the Map2Map directorylocation.Congratulations! You have successfully implemented Map2Map for your veryown study area and modeling purposes.214
Appendix BMap2Map CD Content1 CD Data Structure1.1 Main FilesThe main files stored in the Map2Map CD are:• Readme.doc – contains a step-by-step tutorial for implementingMap2Map on the Rosillo Creek pilot project• Map2Map.tbx – The Map2Map toolbox for ArcGIS 9 Model Builder• RosilloFull.mdb – Geodatabase with Arc Hydro data model for theRosillo Creek pilot case study• Map2Map.mxd – ArcMap document with saved configuration for RosilloCreek from which Map2Map can be executed1.2 Data DirectoriesThe Map2Map CD contains the following data directories:• DLLs – folder that contains all DLLs used by the customized script toolso Radar2GDB.dllo TSTransfer.dllo GDB2HMSDSS.dllo HMSCaller.dllo DSS2GDB.dllo GDB2RASDSS.dllo RASCaller.dllo SDF2XML.dllo XML2XSElev.dllo Freq2Filename.dllo TableOps.dllo DelTableRecords.dllo DStorm2HMS.dllo Heclib50.dllo AccessFTP.dll215
