A source of Geo Data in Overture is any data set where the value varies by location. A common example of geo data is terrain, as the terrain height varies by location. Geo data sets provide the inputs all of Overture's analyses, maps and statistics.

Overture groups geo data sources by type. For example, a source of terrain data is considered to be of type distance, as the value at each point represents a distance. The main types of geo data supported by Overture are listed below:

• Categorical This represents geo data sets where the value at each location can only take one of a given set of values. Clutter and land use data are good examples of this geo data type.
• Gain. This represents data sets where the value at each location is a gain value. An example of gain geo data is path loss, where the value at each point represents the signal loss between the site and the receiver.
• Power. This represents data sets where the value at each location is a power value. An example of power geo data would be RSSI, where the value at each point represents a signal strength.
• Angle. This represents data sets where the value at each location is an angle. An example of angle geo data would be a grid of inclination angles from the receiver to the transmitter, as might be used as an input to a prediction model.
• Numeric. This represents data sets where the value at each location is a number. Examples of this data type would be population or business counts.
• Probability. This represents data sets where the value at each location is a probability. An example of this data type is the coverage probability.
• Density. This represents data sets where the value at each location is a density value. An example of this data type would be the number of subscribers per square mile.
• Distance. This represents data sets where the value at each location is a distance value. The most common example of this data type is terrain, where the distance represents the height above sea-level.

Overture also provides extensive support for combining and transforming geo data sets from one type to another.

All geo data types are automatically added to the Data Browser.
