Terragear needs three different pieces of information to generate scenery.  
Terragear uses three different kinds of information to generate scenery.  


* The elevation of the land (provided by SRTM)  
# The elevation of the land (provided by SRTM)  
* The location and layout of airports (provided by apt.dat)  
# The location and layout of airports (provided by apt.dat)  
* Whether a given lat/lon is sea, land, city, forest, town, road, railway (provided by VMAP0)  
# Whether a given lat/lon is sea, land, city, forest, town, road, railway (provided by VMAP0)  


We'll deal with each of these data types in turn, from how to get hold of the data, through pre-processing. Finally, we'll describe how to bring it together into data that FlightGear can use.  
This article describes how obtain and process each of these types of data in order, and bring it together for use by FlightGear.  The order of these steps is important.  For example, the airport data step needs the elevation data to determine the elevation of the airports.


The order in which we complete these steps is important- for example the airport data relies on the elevation data to determine the elevation of the airports.
