STEP 2: ACQUIRE AND IMPORT REAL LIFE SATMAPS After you have done the heightmap, you now need satellite textures that will be drawn by the game in bigger distances, i.e. ZGM Arma 2 Map making Tutorial The import is done! Now to convince yourself that everything worked properly: GLOBAL MAPPER ASTER DGEM The result after some few more seconds and a zoomout: Now you see that VISITOR 3 exactly recognized the values we entered in GLOBAL MAPPER press OK. ZGM Arma 2 Map making Tutorial Depending on the file size, it might take some seconds now. In the main window, click on PROJECT, then OPEN and in the following dialog you select *.xyz file and select the file you saved with GLOBAL MAPPER. Now we want to import that *.xyz file into VISITOR 3. After clicking OK, a dialog to save the *.xyz file will appear. In EXPORT BOUNDS tab, select the bottom option CROP TO SELECTED AREA FEATURES. In the OPTIONS tab, select SPACE under COORDINATE SEPARATOR and under RESOLUTION 10 meters both for X and Y axis. For exporting the underlying height data into a visitor-readable format, you have to keep the square area selected, go to FILE, then EXPORT RASTER AND ELEVATION DATA and the EXPORT XYZ GRID.
Now select your desired area by moving the square into according position. ZGM Arma 2 Map making Tutorial In the upcoming dialog, I recommend you select OPEN STREET MAPS.

To get a better idea where your selection is located in real life, click on DOWNLOAD ONLINE DATA (globe icon): Now you can move the square where ever you want it to by selecting the whole square with the mouse and left click, then a right click and selecting MOVE AREA FEATURE from the context menu: Do a rightclick and in the context menu, select the bottom option SHOW AREA AND LINE VERTICES. At first, you unhide the so-called vertices of the square. What you want to do now is to move that square to the area we want to have it. ZGM Arma 2 Map making Tutorial When you close this dialog, a naming dialog appears. Find a good balance here and remember: you don't work several months on a map just for yourself, you work for users that want to play on it. That means more work for you, a later release date and more CPU load. Note that the larger the land mass is, the more it has to be filled with objects. Most user maps out there (that have been released yet) are either way 5x5km or 10x10km in size. Note that this has to be an exponentiation of 2. Now you have to decide how big your ARMA2 map shall be and enter the according values in the Width and Height field. You go for CORNER w/ Size - Global Projection (UTM - meters). Then do a rightclick right on the DEM, in the appearing context menu you select CREATE AREA SHAPES, then CREATE RECTANGULAR/SQUARE AREA (SPECIFY COORDINATES). To do this select the DIGITIZER tool (pen icon): ZGM Arma 2 Map making Tutorial Now you need to select a map area from this raw DEM. If you did it properly, the merged DEM should look somewhat like this now: Go to TOOLS > CONFIGURATION > PROJECTION and select UTM or MERCATOR. After that, the screen with the DEM will look like this: Select all downloaded tiles (if you should have more than 1) and the program will automatically merge them. In this tutorial, I use version 11:Įxecute Global Mapper, in main screen click OPEN YOUR OWN DATA FILES. For the conversion of these DEM-TIFFS to a Visitor-readable format, I recommend GLOBAL MAPPER. Dump the "_num" files, you don't need them for the heightmap. You will most likely get "SILC TIFF" files after the download, which are named: ASTGTM_NXXEXX_dem, depending on your desired area. You have just to go through the registering process and the rest is self-explanatory: select your desired area and download the data for it.ĪSTER GDEM EXPLORER 1 ASTER GDEM EXPLORER 2 The acquisition of the data is easy to understand. To get a better resolution, you have to pay quite a lot.

However, personally, I recommend a NASA website from the ASTER project, as the data from this project has a fairly high resolution and its totally free of charge. You can find these files anywhere on the web. STEP 1: ACQUIRE, CONVERT AND IMPORT A REAL LIFE HEIGHTMAP Get a DEM (Digital Elevation Model) of your desired area on the planet.
