FS2005 is a Mesh-scenery based data set that covers the entire globe. This is to be used with the flight simulation suites and comes as an add–on. This is delivered in 3 DVD set that open up about 14 GB of scenery data on your hard disk. The installation support is available in the form of a detailed manual and an online support. In addition, there is diagnostic software available as a download which detects installation problems and helps correct them.
FS Global 2005, which is the 3rd Edition of production of such datasets, is a Global Elevation Mesh-Scenery add-on based on latest SRTM data. Most important point to observe is its global coverage while other similar datasets tended to be limited and regional. Mesh sceneries are like laying objects on a canvas for use in simulation. The dataset objects can be put together as scenery but a standard system of hierarchy is to be followed in making simulation scenarios that work.
At the top of hierarchy is the basic “Shape" or Elevation Mesh. This is actually basic scenery which gives out the elevation of each point on the mesh. The deciding rule is that the higher resolution overrides lower resolution data.
Next in hierarchy is "Color" or Land Class Scenery this enables the textures of each cell of a grid scenery covering objects like trees and buildings.
Third in hierarchy, is "Objects" or Vector Scenery this is dealing in coordinates and polygons and help decide the shape of objects like coastlines, water bodies, rivers and roads and buildings.
Fourth in hierarchy, are “Aviation Objects” like navigation aids, runways, airports etc.
Fifth and the last on the hierarchy, is “Dynamic Scenery” which is nothing but moving things like cars, vehicles or other airplanes, cars or any other vehicle. Using this hierarchy one can build innumerable scenarios seamlessly and use the background as a dynamic flight simulation theater.
