User:Cmadsen/GSSHA Workflow

To set up a groundwater model in GSSHA with SMS, do the following:

1. Start a new SMS project.
1. Start SMS, or clear existing projects in SMS. If SMS is already running, select File | Delete All. A new project can also be started by using CTRL + N. 2. Set the display projection. Select the Display | Projection... command. Set the horizontal and vertical projection using the Display Projection dialog.

2. Import data.

1. Gather and open image files. Images are imported into the GIS module in SMS. 1. Open local images. Load images from local computer files using the File | Open... command. Alternatively, drag and drop the file into the Graphics Window in SMS. 2. Import images from the web. 1. Import static images. Use the File | Import from Web command. Select a location in the Virtual Map Locator. Set a projection for the project using the Display Projections dialog. Use the Data Service Options dialog to select a web service or catalog. Use the Advanced options if needing to access a unique or unavailable data source. Save the data file and import the data into SMS. 2. Import dynamic images. Use the File | Add Online Maps command. Select a location in the Virtual Map Locator. Set a projection for the project using the Display Projections dialog. Use the Data Service Options dialog to select a web service or catalog. Save the data file and import the data into SMS. 2. Gather and open geometric data files. 1. Import map data. Use the File | Open... command to import map data such as Map files, boundary ID files, or boundary XY files. Alternately, drag and drop the file into the Graphics Window in SMS. 2. Import GIS data. Use the File | Open... command to import GIS data files such as Shapefiles, MIF/MID files, Lidar files, or raster files. Alternatively, drag and drop the file into the Graphics Window in SMS. 3. Import scatter data. Use File | Open... to open files with scatter data such as scatter point files, ASCII dataset files, binary dataset files, tabular data files, or XYZ files. Alternatively, drag and drop the file into the Graphics Window in SMS. Use the File Import Wizard to specify how to import the data. 4. Import CAD data. Verify the CAD file type is readable by SMS before importing it. SMS can import DXF and DWG files. Use the File | Open... command to launch the Open dialog (or drag and drop) to import the CAD files. The data should load in layers into the Project Explorer. 5. Review and set object projections. Right-click on an object in the Project Explorer and select the Projection command. Set the horizontal and vertical projection using the Object Projection dialog. To set a global projection, use the Horizontal Projection dialog.
