3dGeoExplorer Program Guide System Requirement Overview 2 Clicks Away From 3d Scenery Tools: Buttons And Cursors GIS Layer Box Internet Box 3d Scenery Control Back to top System Requirement Basic Set-up Operating system: Windows XP Video card: 16M RAM: 256M Processor: 800MHz Internet speed connection: DSL or higher is recommanded. For a 56K modem, a regular download(~10 Megs) can last 40 mins. Disk Space: Demo  distribution(including Kauai Island) require less than 10 Megs, add 400 Megs if you decide to buy and see other area.    Back to top Overview There's 3 basic steps: 1) A World wide Map 2) A UTM Map (Universal Transverse Mercator projection) 3) The 3d Scenery In order to proceed from one step to the other, left-click on the map with the arrow cursor. Here is a screenshot of the Hawaiian Island Kauai from the UTM Map step. Back to top 2 Clicks Away From 3d Scenery If you already downloaded your area of interest, it's true. Otherwise, add 2 more clicks. 1) On the World Map, green squares show Utm Maps that you have on your computer(area_local-available) and red squares show those that are available to download from server(area_net-available). Once a new Utm Map has been downloaded, the square change from red to green and by clicking in it again you can proceed for the next step. 2) On UTM Map, red squares are not shown and you can click anywhere(except borders area) to download the data of this area. Once downloaded, green squares show up and by clicking in it you can access into the 3d scenery. 3) In the 3d scenery, you move the direction of the camera by moving your mouse. It is possible to move in one direction and look in any other direction. See below for more details on how to fly in the scenery. Press "Escape" to go back to UTM Map.

When you download data, those are group in small packets. If for any reason a download is interrupted, all packet allready on your computer are not lost and the program will refresh the layer area_local_available next time you open that Utm Map.

Speed

1	Set to 0 Km/h
2	Increase by 200 Km/h (from 0 to 200, increase by 100 Km/h).
3	Decrease by 200 Km/h.
4	Set to 2400 Km/h, next set to 4800 Km/h.

V	Correction/flying cockpit info, you'll see corrX and corrZ value, if no cockpit is shown press "c".
A	Move 3d frame to the south, corrX increase.
Z	Move 3d frame to the North, corrX decrease.
S	Move 3d frame to the West, corrZ increase.
X	Move 3d frame to the East, corrZ decrease.
