GIS Terrain Sizes

by Adam Schofield · in Torque Game Engine Advanced · 11/13/2004 (6:29 pm) · 6 replies

Just wondering if there are any details about the size of the future TSE terrain maps with respect to real world distances in the up coming Mile Stone 2 release, or improvements to the terrain engine that has already been implemented.

Currently the TGE map size is 1 mile squared (1.66 kms) - according to Desmond Fletcher's tutorial on 'Creating Terrain from GIS Data' and this distance can be increased to 4.13 miles (6.65 kms) by increasing the Terrain squareSize with an obvious reduction in detail.

We are currently using a dataset of Mt. St. Helens for testing. It is to scale.

@ Ben

So would i be correct in assuming that the dataset of Mt. St. Helens your using is 1 to 2 miles larges than a 4.13 mile square map? As the visible area of the volcano within the fog view distance appears to be just past the 1500 metre high shelf?

Adam - not sure I follow. Our visible distance for the terrain demo is also a bit higher... Something like 10km last I checked.

I was just estimating the size of the Mt. St Helens TSE map by sight, i.e. there is a plateau at 1500 metres above sea level, that has a diametre between 3 and 4 miles. In the TSE image of the volcano this shelf is clearly visable and the fog appears just past this.

So would i also be right in assuming that the map doesn't tile for several more km's into the fog? making the map >12kms or >15kms squared.

Something like that. Don't have it in front of me. It's quite a lot of geometry and height data, though. :)
