Creating a GeoSWMM Project Geodatabase in ArcGIS Pro Map
A user can easily create a GeoSWMM project geodatabase if the GeoSWMM add-in is installed in their ArcGIS Pro. The GeoSWMM add-in tab allows the user to create or open any new or existing SWMM geodatabase (see the Quick Start Tutorial). Note that the Map file in ArcGIS Pro must have a proper coordinate system present in its data frame in order to create a GeoSWMM project geodatabase. A user may create or open multiple GeoSWMM geodatabases in the same project but GeoSWMM only allows the user to work on a single SWMM model at a time. In the case of multiple GeoSWMM project geodatabases with different projection systems, the model may often produce erroneous computation results and therefore it is strongly recommended that GeoSWMM users maintain consistency of the coordinate system of GeoSWMM projects and the ArcGIS Pro map data frame.
Although it has been already demonstrated about how to create a GeoSWMM project geodatabase in the Quick Start Tutorial chapter of this manual, the general steps of this process are reiterated here for convenience. It is assumed that the Map file in ArcGIS Pro data frame has an appropriate coordinate system present prior to creating a new GeoSWMM project.
- Go to the GeoSWMM tab. Click on Project menu and it will display the items as shown in the following Fig. 57.

- Click on New. A file name assigning dialog box will appear like the following Fig. 58. Enter the directory and the GeoSWMM project name with a .gdb geodatabase extension. You can also specify the file name and location using browse. Set appropriate project coordinate system. After entering an appropriate file name with directory and project coordinate system, click OK to exit from the window.

- It only takes a few moments to create the GeoSWMM project geodatabase and to open it in ArcGIS Pro map. Notice that the geodatabase is created with a set of feature classes that are displayed in the TOC of ArcGIS Pro (Fig. 59). The GeoSWMM Object Panel will also appear in ArcGIS Pro map. A notification will display if the geodatabase is created and opened in ArcGIS Pro map successfully. Now you can start model building in GeoSWMM.
