Here is the documentation: Offline maps | CyberTracker Wiki.
What formats are your maps in?

Thanks, i went through it but it still isn’t working for me. under distribution where it says to go to file>>> install package. i dont have that option.

i am trying to use ESRI shapefiles and TIFs

That’s on the desktop. On mobile, you need to go to Settings→Offline maps and click “+” at the bottom. Then navigate to the zip file with your maps in it.

If I have a field map in Desktop classic (e.g. a tif with the coordinates in map settings) can I use it to built an Offline Map? Which steps need to be done?

Hi Holger,

Here are the instructions:

Essentially for a TIF, you just need to put the TIF and TFW file in a zip and the add it on the device via the Offline maps page.

It works! Because I have no GIS or similar tools, I need the help of ChatGPT to calculate the twf.

  1. take the tif from classic maps

  2. get the coordinates from the top, left and right, bottom

  3. read the size if tif in Pixel

  4. let calculate and edit the twf

    example:
    left, top: lon 8,8937 / lat 50,55808
    right, bottom: lon 13,84641 / lat 47,19414
    size 27752 x 18852 Pixel

.twf
0.00017846479533
0.0
0.0
-0.00017844027160
8.89378923240
50.55799077986

it means:
Pixel size in X-direction
Rotation around Y (usually 0)
Rotation around X (usually 0)
Pixel size in Y-direction (usually negative)
X-coordinate of the center of the top-left pixel
Y-coordinate of the center of the top-left pixel

Congrats, it’s so cool that AI opens this up.

Here is a little creator for the “GeoWorld”-Files. I hope it works for the classic users who had Maps inside Report in CT-Desktop and want to use as offline maps.
Unfortunately I cannot upload html-Files. So, save the code from Dropbox-Link in html-File and open in browser. English version: “GeoWorld_EN.html” / German version: “GeoWorld_GE.html”
