Recently
I have searched all over the net and I found out that there are not too many usable tutorials on how to create your own 3D topographic maps.
Topographic
maps are designed to be used as a basemap and as a reference map.
The map service includes administrative boundaries, cities, water
features, physiographic features, parks, landmarks, highways, roads,
railways, airports, and buildings overlaid on land cover and shaded
relief for added context.
So in this Tutorial I will show you how to Make your own Topo 3D maps with CompeGPS Land for your Android Device
First you have to download CompeGPS Land from HERE for your PC. You can find trial version also.
Also you will need Two Nav from HERE for your Android.
Now if you downloaded this two apps one for your PC and second one for your Android Device
CompeGPS Lang is software for creating and converting 2D,3D maps
Two Nav is app for Android that can read topographic maps created with CompeGPS Lang
Also you MUST find Topo Maps in most common formats like:.ecw, *.bmp, *kmz, *.jpg, *.tif, *.tiff, *.png...
Now lets get started -----
-Install and run CompeGPS Lang on your PC
-in the main window press on "Maps" button
-now press import maps
- in the window that will poup select your map
-in the next box just click OK
-now again in the next box click again an this window will appear
-if you want to change Projection than click on "Projection Automatic" if you don't than press on "Next"
-again in the next window where it asks you "Modify Map corners" click "Next"
-now this is the vital part
-in this window you will have to choose the two calibration points
-zoom the map and choose some place that is easy to find on other Maps. For example:crossroad;sity square etc.
-minimize the CompeGPS lang window and open Google Maps/Earth or some other Map software and find the same point that you have mark before in CompeGPS
-write down the coordinates from Google Earth in to the empty boxes in CompeGPS Lang
-repeat this procedure with at least one more point
But i will recommend to you to add some additional points because more points in calibration process will make your map more accurate
When you finish with adding points click on "Save"
Calibration file will be saved on your Desktop
So now you will have to convert your saved Calibration file in to a map that your Two Nav for Android app can read
-close all CompeGPS Lang windows and run the software again
-again choose "Maps" from the main window and than "Batch convert raster maps"
-in the window that will popup choose your Saved Calibration file
DO NOT choose your non calibrated map
-in the next popup choose RMAP and press OK
-after the converting process will finish your RMAP file will be saved on your Desktop
DONE:Now you have 2D/3D Map for your Android Device
