    Not to be mad on the whole Mapthis program, but if i download a map of whole of Benelux its 8 gb's large says GMDL ? (4096 x 4096)
    Thats very strange because Tomtom has maps of whole western Europe (even on street level) on a 512mb SD card.

    So i think maps should be made smaller.

    tomtom uses vector data while google maps (and therefore Map This use images.
    Image is not the most effecient format in terms of space, but that's the only world wide free source of more or less reliable map data...
    Try to select a different zoom range - you may trim your map to ~1-2 gig or less

    As Deniska pointed out, since MapThis! uses images, size is all in the zoom ranges. I - for example - have a whole Earth in 64MB! Look at the picture in the below thread and note the zoom level is not fully zoomed in yet! I skip every 2nd zoom level to reduce the size also... This is the 64MB for the whole Earth :

    Ok MIB.42, but i have a car, not a plane :rofl:

    Ok but now serious. Is there a way to downsize the images ? Because when i have a photograph of my garden in photoshop, i can save it for web use. It decreases in size, because of the image having more blocks, instead of smooth display.

    In other words: if we can compress the image files, maps can be smaller.
    Or we can use a different file format, now its JPG (correct me if i'm wrong), maybe we can use PNG or 16 color bmp.

    I was thinking that the maps could be WAY smaller when we port them to grayscale, because you don't need color to have a GPS right

    You can "unzip" your map in to a directory structure with lot's of images, using gmdl's GPSFS-> button. Then you can batch process all images in that directory with photoshop.. after that zip it back with gmdl tool...
    this may save you ~20% in terms of space....
    just make sure that your resulting images are either pngs or jpegs...

    Default Making smaller maps

    A couple of tips to decrease the size of your maps:
    1. Create map using "no GPSFS" option.
    2. Do a search within the resulting .PNG files for any files less than 300bytes in size.
    3. Delete all of these files. They are 99% useless as they tend to be tiles containing only one colour, or useless information.
    4. Batch process all other .PNG's using Photoshop or other image batch processor, making sure you compress the files as much as possible.
    5. Finally recompress all the files using ->GPSFS in GMDL software.

    Hope this helps anyone running out of space on their MS
