To add a base map, follow these steps: 

1. Create a new sheet on the application and switch to Edit mode, as demonstrated in the following screenshot:

2. Add a custom object of type GeoAnalytics Map to your sheet by dragging and dropping the extension, as shown in the following screenshot:

3. Check whether the main settings are set as per the values presented in the following screenshot:

4. The most important setting is the Base Map setting, where we can find the following options:

Basically, they are a combination of projections (Mercator or Adaptive) and background images, and include the following:

• Empty (WGS-84), Empty (undefined meters) and Empty (Mercator)—these base maps do not have a background image, but they apply projections. Empty background maps are useful if you want to use your own background using a geodata layer.
• The Default option (the base map) is a greenish background map using the Mercator projection.
• The Plain Map option is a pale background map with a few details using the Mercator projection.
• Default Server Rendered displays the similar map as the Default option, but it is rendered at the server, which can be more efficient in some device, such as smartphones.
• Plain Adaptive is the same as Plain Map, and uses the Adaptive projection.
• Default Adaptive is the same as the Default map, and uses the Adaptive projection.

A few other settings are as follows: 

• Server URL: If you're using GeoAnalytics installed on premise, check if this parameter is set to your installation. If not, then leave it blank.
• Map ID: This read-only field shows the ID of your map. This is only meaningful if you have two or more maps on the same sheet, so you can set your layers accordingly with the help of this ID.
• Show Labels: When unchecked, the labels in the client-rendered base maps are turned off.
• Zoom to Selection: When checked, if the user make selections to the application, the map zooms according to the selections.
• Auto Select: When checked, zooming and panning will make selections based on visible area. This option only works if the spatial index operation from the GeoAnalytics connector was used while your data was loaded. This operation is beyond the scope of this book and can be found in the GeoAnalytics documentation.
