Funny, they are all I've ever used for the past 10 years, never really used the non-aviation models.  When I get a chance I will make a Types test file and see if I can uncover more info on the subset of types that the aviation units will render.

Thanks again,

Owen

Sorry Boyd, I got busy flying everyday and didn't check back in here till just now.

I accidentally left the GPS in the helicopter tonight, but will check when I am out there next time.  I'm pretty sure that there is a .System folder as I had gone looking for hidden files previously.  I'll let you know what I find.

So far my scripts are working nicely with your guys' help.  I have 5 mapsets for each layer I want to be able to turn on or off depending what kind of flying I am doing or where and then one general gmapsupp.img file with a 'name' element set that tells me how current the data is when I put the card in
#4
Hi guys, one more question.

Do you know of a way of forcing the visibility of a mapset to be either On or Off when the GPS boots up.  I've generated several layers worth of data and I'd like some of them to be visible by default and others hidden.

When I 'touch' through to the Map Info page I can turn them on or off there, but I'm thinking about the KML equivalent of the 'open' tag.

#5
Hmmm.. perhaps I am not as clever as I thought/hoped, but I can't find a copy of gmapbmap.img on the Aera 796.  Is there one I can download somewhere that might show the icons?  I plugged in the 796 with the USB cable and searched the internal memory, but no luck.
#6
Thanks Boyd, that is not precisely what I'm looking to do, but it does open up lots of potential.  I'll be making a donation and getting a couple of those tools.

The Area 796 seems very selective about the TYPs it is prepared to render.  For example it does about 20 of the blocks on the marine test IMG file from cGPSmapper.  I will adapt his file to test out the various Aviation datatypes.  I'm not sure if I can extract the aviation database/IMG file from the unit itself to run backwards through the tool you suggested but I'll take a look.

I'm very happy to have found this website/resource.  I fly helicopter mostly and work on this project part time, mostly as a way to build tools to make my job easier.  My background is as a software eng but I don't get to do it much anymore.  I had been working in a bit of a black hole for the past year as I try and figure out how best to build a workflow bridge between two systems (Garmin Aera 696 and 796s and our internal geophysical processing software).

Cheers

Thanks so much PopeJ and Boyd.  I actually just finished doing a test exactly as you suggested and it worked... and then read your post :)

I can integrate this into my scripts now no problem and the Aera 796 works as expect (as an nMap device). 

On a side note, do you know if anyone has ever produce a test file of all POI / Polygon Type of all the possible types that INCLUDES the aviation types?  I see in the cGPSmapper folder type test for lots of marine stuff, some of which render on the Aera 796. 

If such a thing does not exist, I might endeavor to make one and post it here.

Thanks so much guys,

Owen

Thanks guys,

I need to come up with as automated a solution as possible to generate daily updated maps for our pilots.  As it is, I have them run a DOS script, which later prompts for the SD card to be inserted, copies the files over and then repeats for X number of SD cards.  Asking the flight crews (who are not technically proficient necessarily) to also use Basecamp would be the thing that stops them from using this tool.

So if I understand right, the only way to set a FID and display name is with Basecamp or Map Source?  If yes, is there a way of scripting this step to load the files on the SD card?

Mapset Toolkit appears to allow for the setting of the FID (by way of creating the MP preview file and letting cGPSmapper compile it).  But when I look at the resulting IMG files the FID isn't set.

Today I will try and create my own preview MP files by hand and compile them using cGPSmapper.  I was reading the docs last night and believe I understand the task at hand

I have also been experimenting with the ID element, trying to make them unique.  The cGPSmapper docs talk about always setting it to 1 - which didn't strike me as right.

Thanks guys!

I'm not familiar with MapSource or Basemap, but did download it earlier today.  I've just rerun the MSTK and they do in fact appear in Basecamp and are appropriate.  I am also downloading MapSource, but I understand it is deprecated now.

Hi all,

Thanks for the feedback.

Perhaps where I have been going wrong is that I am creating the maps from our internal data sources and generate a MP file by hand.  I've been compiling them with the latest version of cGPSmapper and taking the resulting IMG file and placing it on the SD card (in either 'garmin' or 'map'). 

After returning to the cGPSmapper documentation with Boyd's hint at looking at the FID I am trying to learn more about mapsets.

Can you have multiple mapsets installed (assume the newer general use handhelds)?
Can you enable one mapset at a time?

I can figure out how to compile a mapset, for just one of my [IMG] defining MP files at a time and uniquely set the FID and MapSet name - but that will be tomorrow's project.

I've tried following the steps suggested to use mapSetToolkit - but when I look at the resulting mapset-IMG file using GMapTool it doesn't appear to have set a FID at all, and the MapSet Name is missing as the Garmin 796 simply writes 'Card Map' in the Map Info Section.
see output from GMapTool 'details' below:

I also noticed that the Garmin will read the first .IMG file in the map directory (sort alphabetically) and display it, but not others.

This is all complicated stuff, but a challenge, thanks for your help guys

Below is the output from GMapTool - Details page for one of my MP Files -> IMG -> GMapTool to a MapSet (with a single IMG) - it doesn't appear to set the FID properly - am I doing something wrong?

Hi,

I am writing custom mapping tools for use with the Garmin Area 796 aviation GPS (the most recent hw/sw versions) and I have a unique requirement.

I have IMG files that define our survey lines, but depending on the day sometimes I want to see IMG 1 for an hour and then IMG 2 for a while (without being cluttered with IMG 1 anymore).

I know I could produce separate gmapsupp.img files for each use case and put them on different SD cards, but this doesn't scale to the 6 or so layers (IMG files) I want to produce and update daily before we leave the office.

The 796 has a Map Info page where you can select an 'map or mapset' by a given name (but it usually just says cGPSmapper version0100d - which I do a binary search and replace on to the name I want).

The problem is that if I load 6 IMG files into the SD:\map directory they all render ok, but only 1 of 6 show up as a show/hide option on the Map Info page. 

Has anyone run into this before?  Is there another way to load several IMG files without combining/joining them to be able hide/show them at will?

Thanks,
