2D & 3D Visualization Techniques for Geo-Referenced Images

URL: http://www.codeguru.com/Cpp/G-M/bitmap/viewers/print.php/c9187__1/

this article covers the following topics:

Working with the Map Projection Library
Map projections
Using the map projection library
Forward projections
Inverse projections
Projections without the library
Working with the GeoTIFF Library
Common tags and variants
Displaying Geo-referenced Images
2D image display
3D image display
Additional information about the sample project

The goal is to implement the following capabilities:

Load a GeoTIFF image file into a DIB section and decode the geo-referencing information
Show the image in 2D and display the geographic and UTM coordinates of the mouse location and enable the use to select points
Show a 3D perspective image of the GeoTIFF and enable the user to select points on the 3D view
Display a first person and non–first-person fly through of the image, similar to those shown on cable news shows
