map sizes

I'm living at the corner of 3 map areas, to get all the data I want for cycling (looking to transfer maps onto new Garmin 520) I have to download 3 areas together, giving a total file size of 46Mb. The Garmin has only 50Mb memory.
Is there any way I can reduce the size or area of the maps to give a smaller file size and so my location is centred on the area I need?

Re: map sizes

This gives me one map that covers the whole of northern Europe and is 88Mb in size. I can't fit that on the Garmin. Can these maps be scaled down to give a smaller area?
I'm looking for a detailed map that covers Yorkshire/Derbyshire area and will not take up too much space.

Re: map sizes

These are simple maps with tiles up to 3.5MB. Install map on PC and use MapInstall to send required area to device.

Re: map sizes

I'm struggling to find a working mac version of this which allows me to strip down the big NW europe map into manageable local tiles.

Re: map sizes

I'm not sure, if you are talking about my maps form http://www.gmaptool.eu/en/content/europe
Actually my maps can be installed on Mac.

I clicked the Mac OS X install and it gives me a command line prompt which is a bit too technical for me to sort. I'm looking for a map of west yorkshire + derbyshire region that is no more than about 20mb in size. Can you help guide me through what I have to do with the big NW europe map to trim it down to the tiles I need, that I can fit onto the new Garmin?

Re: map sizes

You could try the http://extract.bbbike.org garmin suitable maps which will allow you to adjust a poylgon shape surrounding just the area you require.

I don't provide any install for Mac. Here is short info how to install maps: http://www.gmaptool.eu/en/content/installation

Thanks! This looks pretty great for selecting the right area. I'm guessing Garmin cycle format best to use, if I can get it to transfer over to the Edge 520 (when it arrives...)

This is very user-friendly for selecting and downloading an area as a gpsupp.img, but I cannot then install the img into Basecamp. I've spent hours trawling through google searches and gps/mapping tools but there doesn't seem to be anything for the mac? I want to be able to preview the image files and install them into basecamp.

Re: map sizes

I found 2 solutions for the Mac, to check the map areas in Basecamp once downloaded from bbbike. I plugged in the Garmin Edge 500 which although it doesn't support maps, basecamp recognises it as a legitimate device to read the gmapsupp.img files from - just copy into the device Garmin folder.
I also found omg files in a Garmin folder on SD card worked the same (and was quicker) whereas when I tried it with a USB stick, basecamp would not recognise it as a legitimate device.
