Get Started: Shapefiles and Shapes
Introduction
Shapefiles and shapes are created or uploaded in Map Studio and are then made available throughout IFTDSS whenever a mask or area of interest is required.
Note: Shapefile vs. Shape?
"Shapefiles" include both the geometric area, as well as accompanying data, these can be uploaded to IFTDSS from your local machine, and are usually created in ArcMap and similar tools.
"Shapes" include only the geometric area, no associated data. These are created in Map Studio either by drawing or copying with Create / Edit Shapes.
Both shapes and shapefiles may be used as masks and areas of interest throughout IFTDSS
How to Create Shapes in IFTDSS
This example will describe the creation of polygons, you may also create lines and points. To create a shape, go to Map Studio and click the Create/Edit Shapes widget .

How to Upload Shapefiles
Important! Shapefiles are added to Map Studio as .zip files. The .zip file must contain the .shp, .shx, .dbf, and .prj files that comprise the shapefile.
- Click the Upload Shapefile widget
along the bottom of Map Studio to open the widget.
-
Click Upload File. A browser box will open allowing you to search your local files. Select the desired shapefile. Shapefiles must be zipped to be uploaded and contain .shp, .shx, .dbf., and .prj files.
Note: Large or complex shapefiles may take longer to load as IFTDSS reprojects the file and repairs geometery if needed.
Tip: You can cancel the upload, if needed, at anytime by clicking the Cancel button.
-
Use the checkbox to select the attributes you wish to import. You may choose up to 10.
- The "Save" option is checked by default. If you do not want to save this shapefile to your Workspace for later use, uncheck this option.

- Specify the folder in which to store the shapefile.
-
Click Save and Add to Map.
-
When completed, a confirmation message will appear to verify the shapefile has been uploaded.
