NEWS:
- Next Step is put DGTV realtime, the idea is to have a GPS connected to portable computer in a car/boat/airplane and see realtime your situation towards the terrain. - SRTM Data for Europe and Asia (Eurasia) were finally released on 9 Nov 2003, few adjustments were made to improve the display of SRTM 3arc *.hgt files.
- Edit and Save Terrain Button is now available - The New file Format DG Geographic Information Macro (GIM) is now developed, it allows to mix vectorial and raster information, only one file is for now available that shows Sattelite fotos, elevation data, railroads, higways and water systems, but it's easy to make a GIM file with GPS Utility and a text editor.
- RELEASE 3 IS NOW DONE, you can view on 3D where you've been using a GPS receiver and the program "GPS Utility"(www.gpsu.co.uk) or GPS Track Maker (www.gpstm.com), and a new color rendering engine, will also have a Vista-Pro like user interface
- DG Terrain Viewer R2.3: GTOPO30 NOW SUPPORTED check the new user-friendly converter!!!
Some Thankyous:
- US Agencies: NGDC/NOAA, JPL, NASA, etc. for keeping free and public their GIS Databases
- Ed Garcia (PH) from www.waypoints.ph, for supplying several GPS files
- Alan Murphy (UK) - The maker of GPS Utility
- Nelson "Zilog" Teles (PT) for supplying some source code
- Nuno Pedrosa - For supplying nice and precise calibration points.

New Features (Release 2.1, 23-September 2002):
-Automatic Screen Capture, Direct Render to picture File on PPM format (Portable Pixel Map)

6 kinds of files Supported:
-GTOPO 30 minutes files
-SRTM 3 arcsec files
-SRTM 1 arcsec files

Objective:

This program is FREEWARE, it allows users to virtual visit and study real Landscapes obtained from the recent mapping mission made by JPL & NASA Space Shuttle Topography Mission(SRTM) Launched on Space Shuttle Endeavour, on February 11, 2000 and flew for 11 days. The instument is a complex high-pressision SAR (Synthetic Aperture Radar), that composed most of the Shuttle's Payload Bay. More information about SRTM can be found on: http://srtm.usgs.gov

This Program is also a demonstration of OpenGL/Visual C++ capabilities. I've made this program only to have some fun.

- By the first time I've successfully achieved to read large files of data (tested files up to 25 MB), distributed by the US National Mapping Agency. This achievement, made me realise that soon, if I want, I will be reading more complex files.

- Using Visual C++, I achived to make a very user-friendly program with buttons and nice windows, the keyboard layout is simple, but if the user wants, he can use the toolbar buttons to move the camera around the landscape.

- Nice graphics were made, thanks to OpenGL (Graphic Libraries), but this time, I realised that if I programmed somethings by myself, such as lights rendering and gouraud shading, the results were pretty ok, but the Graphic Performance was much better then the OpenGL primitives...

- Is now available viewing for the 1arcseg and 3arcseg SRTM or ".hgt" files, you can also read and display ETOPO5 "tbase.bin", GTOPO30 is also supported, it is supplied with DGTV zipfile a proper "select a rectangle on the world" converter

- On May 2003, I've added support to read GPS files, you can now see your tracks and waypoints projected on the terrain mesh. Personaly, I'm using DG Terrain Viewer very enthusiasticly, When I go out to geocaching or ride my bycicle, and use my GPS, when I'm back at home, the first thing I do is turn on the computer and see my track and waypoints over and beetween the mountains.

Screen Shots:

Photo#1 - San Francisco Bay Area.

Photo#2 - Grand Canyon - Colorado, in this picture you can notice the Auto Color Feature.

Photo#3 - Europe from ETOPO5, notice the pretty cool gouraud / smooth shading.

Photo#5 - Timor, Mozambique, Italy, California and the Himalayas all from GTOPO30

Photo#6 - The Nothern Phillpines from GTOPO 30 with a Track and Waypoints from GPS Utility

Photo#7 - Lisbon, this Foto shows the Portuguese macro file, this alows to mix several kinds of geographic information, see the sample on http://aero.ist.utl.pt/~dg

System Requirements:

DG Terrain Viewer will work quite happily on a Windows 95 OSR2 Operating System with a 150 MHz processor, 32 MB of RAM and a 10 MB of free-space in your hard-drive,

Althought is recomended at least a 700 MHz wiht Windows 2000 or Windows XP, an Acellerator Card, 128 MB of RAM.
