Converting JNX to raster IMG

**johuarte** · 21st December 2019, 12:23 AM

Hi Friends.
I´m trying to create some raster .img files.
I created the open Street map files with Global mapper 20.
Then I converted them to .jnx files with the Mobat2jnx.
Now, I´m trying to convert them in .jnx files with Jnx2img but I have an error.

"Error processing JNX file: ´06E70766´is not a valid integer value MTX file was not created. Exiting.

The MOBAT2JNX is the latest versión I downloaded (last week)

Any idea what I am doing wrong?

Thanks Friends.

Hi

Must be a compiler problem

Look in the Tools folder if you have the bld_gmap32 and gmt compilers and in the bld_gmap32 folder the TestLicence.mpl file

I'm having the exact same problem in my RV 770. All other jnx maps in it are working fine.
The converted jnx looks very impressive in Basecamp but the map shows blank in the device. The bounds of the sheet are positioned correctly but no details showing.

Edit: It looks like the RV770 displays JNX fine but may not be compatible with raster .img maps. The raster maps I created otherwise work ok in a Rino 650.

Hi
Can you check with GMapTool if the MS of your card . img is "0" or "1"

I cannot understand your attempt. Open street maps are vector maps with routing function and you can download them for free in Garmin-format.
Why you want to convert them to raster maps, gettig bigger file size and loosing the routing?

between the level 200m to 20m ?

in SASPlanet with a JNX export you can choose the zoom and the level, so I wanted to export to JNX and then convert it to IMG, but I have two problems:
- The export to JNX is split into several files: part1, part2... for a single export. JNX2IMG command does not support multiple part of files ?
- I got errors when converting JNX 2 IMG, about levels and scales

Spoiler: image

the point here is that I assign a different custom raster map between each zoom
3 zooms = 3 custom maps

what the hec?

my test map file is in jnx2img directory. i copied MPC's bld_gmap32.exe to tools

d:\jnx2img>jnx2img.cmd test-1994.jnx test-1994.img
jnx2img, version 1.9

d:\jnx2img>

The only place i have seen the word "please" is when i ran command without copying bld_gmap32.exe asking me to please copy it

what am i missing?
