    Default How to import GIS map into Garmin GPSMAP62?

    I'm looking to use a local GIS map and my Garmin GPSMAP 62 to locate the property lines of a piece of land out in the woods. Is it possible to use a local government GIS website to import a map onto my GPS so i can find, walk and flag the property lines? If so then i'd really appreciate some tips. FWIW I use a PC with Windows 10 and another with Windows 7 professional.

    thanks!

    Your problem might not be so much converting a local authority GIS map to a format usable by your GPSMAP62, but in obtaining the accuracy required to identify a property line using it as the sole or primary means.

    This recent discussion might be helpful to explain the satellite accuracy limitations for handheld GPS devices for such precise uses: [Only registered and activated users can see links. ]

    Thanks for the response Neil. If I can find the general area of the property line +/-30 feet using GPS then that'll be good enough for my needs. I also suspect I'll be able to locate one or two survey markers and work from those to get even closer to the true lines. But without the GIS map on a GPS I'll be swimming in the dark.

    So with that in mind do you know of any method for moving GIS map content onto a GPSMAP 62?

    Thanks again!

    No problem is your target accuracy is +/-30ft/10m. You will get 3 to 5m [10-16ft] SA with most outdoor Garmins in good average conditions. Very easy to locate corner and line pegs in open country with that accuracy provided they still exist of course. If there's been a recent resurvey it'll be easy to find them even in the bush.

    GIS is quite a generic term and although i think most maps are in a basic raster format there may be individual built-in protection which makes them 'proprietary'. However i don't think that's the case with Local Government GIS maps in the US, i have a recollection of reading there are legal precedents where the courts found that the basic GIS information is part of the public domain and as such should be made available by the authority. Therefore it should be no problem to covert their digital GIS mapping data to a form usable by your Garmin. One such program is ExpertGPS:

    I'm by no means a map making expert but we have members who are, perhaps you're get more targeted info in further posts.

    If you can save GIS map in any raster format with embedded geodata the easy way to make JNX format for your device.
    Love your wife? Buy yourself a GPS for answering to her favorite question: "Dear, where are you?".
