The Project Toolbox
The Project Toolbox (Figure 1) offers you the option of saving your map work as a project that you can access at a later date. There are several methods of saving your work, so you can choose the one that works the best for you.

Upload Shapefile (Figure 3)
The Upload Shapefile tool allows you to upload a Shapefile to the Essentials application and have the features presented as a layer within your map. This layer will function the same way as other map layers, allowing you to perform all the same operations (navigating the layer, identifying and selecting features, viewing legend, etc.) as well as save the layer and all associated markup as part of a saved project. To use this function, select the Upload Shapefile tool from the toolbar. Next, fill in the requested information in the Upload Shapefile window that appears, including the name and color of the new layer, along with the file paths for the three files that create a Shapefile (.shp, .dbf, .shx).
