Raster Maps for MGL

Unread post by jagermm » Thu Mar 14, 2019 8:33 pm

Hi All
Does anyone know where to get electronic raster maps all the way from SA to Tanzania for a MGL Efis?
I would prefer aviation maps but ordinary maps would do as well.
If there are no electronic ones around, where would I find paper maps?

Thanks for your help.

Hi

If you have an iEFIS, get the easyplan mgl subscription. That way you can export the newest maps to you MGL.

OK here is how this works:

The iEFIS can use two different map types at the same time. The first is called a vector map. This is based on terrain data and cultural data (towns, roads, rivers, railway lines etc etc). This is preinstalled and covers the planet. On top of this it draws aeronautical information from the Navidata file which can be had from Jeppesen, Easyplan, PocketFMS etc. This would then include airspaces, airports with information such as frequencies and runways, navigation aids, reporting points etc.

The second type you can switch to is called a raster map. This alludes to a pixel based map such as you would find in many digital map images (usually in JPEG or TIFF format). Usually you would use aeronautical maps and indeed, you can download premade maps like this from our website for Southern Africa.

But now things get interesting: There is a little windows based utility you can download from our website called MapMaker 2. What this does is convert any existing images (they could be just hand drawn scanned paper scribbles or something out of a Shell Atlas or whatever map source you have). Mapmaker 2 allows you to georeference the images (give it information on latitude and longitude of at least two points) but it also allows you to translate the map projection to that needed for our systems. It is useful if your source map has something like gridlines you can then place reference points on so Mapmaker can then squeeze and squash your image correctly.

You can have several "zoom" levels and each one could be a different map if you like (taken perhaps from 1:50.000 all the way up to 1:1000000 sources).
The interesting part is that this does not have to be an aeronautical map. You can tell your EFIS to use the raster map you created but still draw your Navidata in top of this. That means in a way you can create your own aeronautical maps !

It gets even better - go onto the MGL user forum - we do not hide our data formats and the result in one enterprising fellow that created a nice utility to pull in maps from all over the place (for example OpenStreetmap servers) and convert them without you even having to bother georeferencing anything.

In addition, you can install several raster maps in parallel on the MGL systems - for example you could have VFR maps and IFR maps at the same time (just flip between the two) and many other map types as well.

It's quite flexible...
Who said the sky is the limit ? I think not.

Thanks Rainier, that's why I'm a MGL flyer , ones you get just a little bit involved you actually see it's a lot easier than it sounds and all based on commonsense
