TSE GIS application
by Adam Schofield · in Torque Game Engine Advanced · 09/14/2005 (8:31 am) · 5 replies
My falt mate just came back from a GIS conference in Melbourne and one of the speakers was using Torque (TGE) to demonstrate its real time GIS application.
The biggest gripe by my flat mate was the terrain texture but what is stopping TSE's functionlity? appart from the limit of jpgs 65K pixels?
I for one have been promoting the TSE to the GIS department of UTAS for its applications other than game development and think now its finally dawned upon them.

Of course we Queenslanders would also benefit from run length compression in JPEGs because of all the yellow used for bananas :)

Lol - surely Tasmania wouldn't be larger than 65K pixels :POf course we Queenslanders would also benefit from run length compression in JPEGs because of all the yellow used for bananas :)

Here are two screenshots based on real data (aerial data from frame camera and push-broom camera) representing real Digital Surface Model textured by the aerial image (no manual editing so that's why it is a little bit smooth).


To do this, I modify a little bit TSE / Atlas and make a small executable allowing to load my dataset and show it. As I said it was only to have a proof of concept and no further work will be done on this app.

I have made a simple 3D GIS data viewer that I'm using for demo purpose. Here are two screenshots based on real data (aerial data from frame camera and push-broom camera) representing real Digital Surface Model textured by the aerial image (no manual editing so that's why it is a little bit smooth).

i love the tree's at the bottom of the first image... I've been looking for a method of doing that for Air Ace... care to share how its done?
youre processing the image using some sort of edge detector and extruding the mesh when an edge is detected?
Man, it just looks great.. houses are a tad weird, but those tree's look sound!! :)

That effect is REALLY nice Frank!!!i love the tree's at the bottom of the first image... I've been looking for a method of doing that for Air Ace... care to share how its done?

To obtain this kind of surface, you have to compute the DSM which is not an easy task. That's why I'm saying these datasets are real datasets. The first image is from a dataset over Le Mans in France, and the second one is over Nagoya city in Japan (I'm working in a mapping company so it's quite easy for me to have access to such dataset).
It might be possible to extrapolate the height from a single image using shape from shading techniques, but I did never experiment it on such dataset.

Tree looks like in 3D because I'm using a dense digital surface model (which have Z point for terrain surface including building and tree) and not a plain digital terrain model (which has Z info only for terrain).To obtain this kind of surface, you have to compute the DSM which is not an easy task.
