Creating a Shapefile Subset from the Attribute Table

Create a subset of shapefiles from a larger shapefile can be performed from the Attribute Table, as well as from the Layer List. These subsets can then be used throughout IFTDSS to represent a specific set of treatments, habitat conditions, etc.

To create a subset using the Attribute Table, with the shape visible in Map Studio, follow the steps below:

  1. Click the Attribute Table widget attribute table on the bottom right of Map Studio.

  2. Ensure the shapefile attributes are listed on the table. If you have multiple features open in Map Studio, there may be several tabs to choose from.

    A magnified view of the top bar on the Attribute Table, showing the Shapefile feature is selected.

  3. Left-click the first object you wish to have contained in your subset, then hold down the control key (or cmd cmd on a Mac) on your keyboard, and continue to left-click the rest of the objects needed, until you have all the objects for your subset selected.

  4. Click Save Selection as Shapefile.

    choose objects from the attribute table

  5. A dialogue box will appear in which you name the shapefile subset, and specify the folder to save it in. When finished, click Save and Add to Map.

    name the new file

  6. The subset of shapes will now be visible in Map Studio, visible in your Layer List, and available for use throughout IFTDSS and in My Workspace. Note that if you pull up the attribute table for your subset, all the data is retained, just as it is in the larger shapefile.

    the new shapefile subset will be visible in map studio.
