DIY: Scan, calibrate and import a Rooftop Map for use in Hema/Memory Map software
Hi All,
After plenty of buggering around, I've managed to sort out how to scan and import my Rooftop's paper maps into the Memory Map application and Hema Navigator on my iPad. So for all of you folks using those applications and who have never tried importing your own map, here comes my step by step guide on how to do it.
There is precious little information on how to do this out there on the interwebs so hopefully it can save someone else the aggro :furious: it has caused me because there are some tricks to it that aren't documented anywhere.
I also plan on undertaking a similar process for importing and calibrating into Maps n Trax, but first things first.........
Step 1: What you need........
Before you can do anything, you're gonna need a paper copy of a Rooftop's map, IMO simply the best maps of the Victorian High Country tracks and historic sites all in one. I bought a new copy of the one I wanted because my existing one is, shall we say, well used and I didn't want the electronic quality compromised.
1. A new paper Rooftop's Map
2. Somebody with a jolly big scanner. I used Officeworks. it cost me about $2 to scan an A1 size original map.
3. A USB drive to put your scan on.
4. A copy of IrfanView; http://www.irfanview.com/
5. A windows PC (mine is XP Pro so cant speak for anything else)
6. A copy of Memory Map Navigator for the PC and $50 to activate the "Import 3rd party maps" option (will also activate this option on your iPad too); http://memory-map.com.au/memory-map-...downloads.html
7. An iPad (or stand alone GPS device but I cant confirm the importation process for one of those).
6. HEMA maps or Memory Map application on your iPhone/iPad.
I think that's about it....
Step 2: The scan and image preparation.
Ok, so hopefully you have the stuff you need.....and I didn't forget anything!
1. Take your USB and your paper map to an Officeworks that has a large format scanner. Anywhere else with a large format scanner will do too and some of the printing places (Minuteman etc.) may be a bit better for giving you more scanning options (which would eliminate one step). Officeworks worked for me though, so we'll stick with that.
2. Request your scan. Ideally you want it as an 8-bit TIFF file. The Officeworks I went to could only do a 24-bit version. This is a higher colour resolution than what is needed (8-bit), but that's ok, we'll fix that shortly......
3. Make sure you're near a BCF or something because the scan can take a little while......go for a browse! LOL
4. I hope you've installed IrfranView 'cause we're going to need that now..........
5. Plug in your USB stick and navigate to it using Windows Explorer. Locate your image and change the file name to one that represents the map you're creating.

6. Open IrfranView, go to the "File" tab and open your recently renamed image. A tip is to disable the preview checkbox, otherwise you will wait a minute or so as it generates a preview image from what is a very large file.

7. Now we want to reduce the overall image colour resolution as I mentioned earlier. We need to reduce this from the scanned image's 24-bit colour back to 8-bit..... Go to the "Image" tab and select reduce colour depth. From the next text box, you want to select "256 colours" and leave everything else as is.

8. Save your reduced image as a TIFF type file to a DIFFERENT location, somewhere you know where to find it. I created a Rooftop maps folder on my desktop and saved it in there so I knew where to find it later, and so I didn't mess with my original scan in case I needed it again later too.......which I did! (but hopefully by following this you wont!).
That's it for this step, more to come soon.......
Step 3: Map calibration continued.......
Well, that's annoying. Just looking at my image posted above, the cursor didn't show up in my screen print....D-Oh......I hope you get the idea anyway!
So now the calibration detail. In the image below you can see the location I selected for one of my reference points and the text box where that UTM coordinate detail gets added. Note the format of the UTM detail in the upper left. On the upper right, you can see two boxes, these are the image coordinates to which the real world UTM data will be attached (explained as best I can).

So if we go back to those original UTM coordinate example shown in the reference point selection (Easting 0439, Northing 5820), the correct format to be entered in the calibration would be:
55S 439000E 5820000N
You need to enter each set of coordinates of YOUR 3 chosen reference points. For each one, enter the UTM data in the above format and then click the "save point" button.
NOTE: I found sometimes when I went to click the "save point" button it would do something random to my carefully entered coordinates and I would have to edit the UTM data. Just keep an eye out for that.
Boundary
You need to set a boundary for your map and the help file is fine with this, except don't be looking for the route you mark at the boundary to turn red when completed. It will turn dark blue. I also needs to be completed in one continuous piece, not segments.
Other than that, if you follow the instructions you should now have all the missing info you need to import your own scanned map quite easily.
I don't imagine once you have the scan completed it will take much more than an hour to do the calibration and import each map.

Good luck with it mate. Let me know if you need any help.....
