Converting JNX to raster IMG

**Allin** · 24th January 2021, 09:37 PM

Hello

Any ideas on how to resolve this?

To start with, with GmapTool I would try to attach (Join) the 1/25000 and 1/50000 files

Thanks Allin

I will give this a try. I will also try making a two level JNX and converting this to an IMG. BTW they are both raster maps.

Hello Allin

I have been doing further tests over the past couple of days. The good news is that with MAPC2MAPC I can make a two-level JPX with the 1-25k and 1-50k layers of raster maps, set the zoom levels in JNX Customizer and convert this JPX to an IMG. This IMG can be viewed in BC and on my device, and changes between the 1-25k and 1-50k mapping according to the zoom level as expected.

The bad news is that if I make a separate JPX for each, choosing the same zoom levels as before and convert to two IMGs before joining them in GMapTool to a single IMG, no matter what settings I adjust, only the 1-50 layer is ever visible in BC or the device when fully zoomed-in. I have tried various zoom/scale levels in creating the JNXs and in GMT, changed the draw priorities, tried a few different TRE parameters (Map Series IDs). I must be missing something important or maybe I am bumping up against a limitation of Alex's method as mentioned in post 1?

Have you been able to able to do this conversion with two separate raster JNXs?

Hello Eyelet99

Have you been able to able to do this conversion with two separate raster JNXs?

Using MAPC2MAPC ==> JNX Customizer ==> Jnx2Img ==> GmapTool.
Alas no I have exactly the same problem as you.
I was counting on you to find a solution.

Hi Allin

Alex was an active contributor to a number of Russian forums in parallel to his contribution here and these are worth a read. I found an interesting tutorial here:

Spoiler: external link

and will be giving this method a try.

Using the above I seem to get a map on my monterra that isnt the full size I selected in sas planet, its much smaller around 3mb seems to be the limit, is this due to the test licence.mpl?
thanks

Anyone got a link to the jnx2img utility? The link in the first post no longer works.
