(I think you’ll need OCAD professional to export GeoTIFF or jpg with world files)

BTW
I found that I could not use custom maps on versions of Mapsource that were higher than 6.13.7. This was some time ago, so the very latest version of Mapsource may work with custom maps.

The process automatically edits your registry, you may like to take a backup of it and/or set a system restore point before continuing.

Add a directory to your C:\ drive to hold the mapsource files. For example C:\WG

Put MapsetToolkit.exe on your C:\

Double click on MapsetToolkit.exe on your C:\

Click on Select IMG files and select the folder where your IMG file is. That will populate the Source IMG files space.

Click on the img file you want in MapSource and then click on Add.

Fill in the directory where the program will assemble the bits and pieces it needs for Mapsource (in this example C:\WG\

Fill in Mapset name with the name you want to see in
Mapsource.

Put in a famlily ID greater than 65530 (Product code and Map version will default, leve copyright info blank.

Fill in the name of the compiled TYP file you want to use. Jan will be able to tell you what this will be called and where it will be stored.

Remember to tick “Install in Mapsource” then click start.

A message will appear, click on Yes.

If you want to remove a map from mapsource. Then select it in the mapset installed panel and click on uninstall.

DOWNLOAD FROM MAPSOURCE TO GPS

Go into Mapsource. Your custom map should be in the list of maps. It looks a bit strange in Mapsource but don’t panic, it will look better on the GPS.

Download the map to your gps using the normal mapsource functions to select it and transfer it. NB you need to select all maps that you want on the GPS as Mapsource clears all maps from the GPS as it’s first step.

I’m not 100% sure if I understand what works/doesn’t work – but I think what you are saying is that you’ve got your OCAD-map converted to a Garmin map (.img-file with accompanying .typ file), and the problem is how to transfer it to your GPS-unit without erasing other maps, i.e. doing it through Mapsource?

I’ve been using a program called MapSetToolKit for this (instructions here http://cypherman1.googlepages.com/intruction_en and download here http://www.box.net/index.php?rm=box_v2_download_shared_file&file_id=f_274264738 ) to transfer maps to Mapsource. There are also some instructions here http://www.gpsfiledepot.com/tutorials/how-to-load-.img-files-into-mapsource-with-mapsettoolkit/ , and it is even possible to make a self-extracting exe-file for the map which you can send to somebody else http://www.gpsfiledepot.com/tutorials/how-to-create-garmin-topo-maps—part-9—compiling-data/ (I’ve not tried the latter). It is a bit involved process, and you might need to have an older version of Mapsource installed (although I am not completely sure about that).

After spending some time on the procedure and with help from Simon (my son) we have been able to download an Ocad 10 map (duly saved as Ocad 9 and Ocad 7 as per instructions), and using Step 2 transfer the image to a Garmin CSx. The image is OK but not as good as the image shown in the conversion article.

We tried Step 1 but as indicated did not work so had to overwrite other maps by using Step 2, although the CSx has the option to change the micro card. Hence keen to find out how to download with Mapsource and checking out how to download without overwriting other maps, such as the Shonky maps which I find to be pretty good for general coverage of Australia.

I had been researching the procedure and found that Martin Lergen from Germany had also been able to do the conversion, but coincidentally he has just informed me of Jans work saying this is a much better and simpler procedure. And I agree.

Well done Jan, great work.

I managed successfuly to upload the sample o-map to my eTrex Vista (see picture bellow). I tried to process some of my own maps. But at the end of the ocad2img I get this error message: “Error E032: Layer 0 of the map cannot be empty”.

2. Richard Valentine Hensby
I have had that error before. Typically when I forgot to go to Options -> Scales, and set “Real World coordinates”. Under coordinate system, choose the correct UTM grid (in my case UTM 32N).

3. Richard Valentine Hensby
Before Jan worked his magic, I had to define every ocad symbol as a bitmap. Jan’s software translates the bit map that is associated with a symbol automatically. Works a treat for 99% of symbols. For line symbols that OCAD depicts with a fancy icon (eg 530.0) or where lines are shown as vertical icons (eg 601.0) you get some odd results. To tidy … Read Morethese up you need to right click on the icon in ocad7 file and edit it’s bit map to be a horizontal line (for 530.0 you can leave gaps in it, for 601.0 make a solid line). Next time you do the conversion it will be a lot tidier. Applying this technique to those odd symbols in the out of bounds area in your screen shot above would be very effective.

4. Richard Valentine Hensby
Pits and small depressions show as upside down for me. Could be because I am “down under” in NZ. I find them quite quaint, so have left them. But could easily be fixed by editing the bit map of the icon in the ocad7 file

5. Richard Valentine Hensby
Just had a quick look at this Meyermarken file and what I did to sort out the anomalies you see on your screen shot. In the ocad7 file redraw the icons for 601.1, 526.4 and 526.5 as horizontal lines. This sorts out the North Line, the building outlines and the canopy outlines. Redraw the 529.2 icon as it is but horizontally instead of vertically. This sorts out the steps that are to the west of the western building.

Thank you Richard! I did not know it uses the bitmap icons. Interesting. With this knowledge I can do some tidying.
