Hi,
I am a german biologist using ArcView as a GIS-program. I usually take an aerial photo (as .jpg-file) and georeference it (make a .jgw-file). Now I want to use the android-app OruxMaps, to take this photo(s) into the field and for example mark some points (bird-nets ....).
Therefore (I guess) I first have to convert the georeferenced aerial photos with the OruxMapsDesktop?!
I tried to do that, but the program does not except the .jgw-file. Please - can someone give me a hint!
The used .jgw-file looks like this:
1.5194390000
0.0000000000
0.0000000000
-1.5194390000
4443289.5954439305
5668837.7393504446
and the values for the projection I wanted use are as follow:
description in german:
Koordinatensystem Gauss-Krüger
Bessel-Ellipsoid
Datum Potsdam
Streifenbreite 3°
Mittelmeridian 12° Ost
Lagestatus 110
EPSG=31468
I think this might mean:
projection: Gauss-Kruger zone 4
date: DHDN Potsdam
spheroid: Bessel (1841 ?)
units: METERS
So many parameters :-(
I searched for the right way to handle (in the internet), but I think .... I need some help !
Thanks! Markus

Hello;
oruxMapsDesktop doesn't support all formats,
please, try with okmap.org I think this tool can read your maps and create oruxmaps maps
orux
Thanx for the answer!!
I will try soon
Markus
