    Mapset toolkit Convert Failed...

    in GPS technology and devices

    Posted

    I have downloaded the file from 'My Link' and get the same messages you do. Tried various versions of MSTK and cgpsmapper with the similiar results. Gpsmapedit will not open the file, says it is corrupted. I would say it is corrupted on the host site, possibly something went wrong when it was created. Either contact them about it or waite until a new version is created.

    help with maps on Garmin Oregon

    The unit should have a very basic world map.

    If you have a PC, Garmin's MapSoruce and/or Basecamp are used to transfer map data to the GPSr.

    There are free maps available at gpsfiledepot.com.

    That site also has tutorials on installing mapsets to the computer, selecting and transfering data to the GPSr, and making you own maps.

    Maps for 450

    in GPS technology and devices

    Overlay/transparent mapsets usually do not have any overview data to display in MapSource/BaseCamp - only the selection quads/segments.

    Select the area based on the coordinates of the pointer and/or display some other mapset which has an overview map and zoom into the area of interest, then switch to the overlay/transparent mapset - the same geographic area should be in the MS/BC display.

    With a 'newer' type unit like your OR450, rename the gmapsupp.img file to somename with a .img extension before you send data from a new mapset to the GPSr; otherwise it will overwrite the existing gmapsupp.img.

    Correct.

     

    For safety reasons, I would back up all the files which came preinstalled on the unit. More for something unforseen happening than for adding mapsets through MapSource/BaseCamp. For these 'factory' files, I have also changed them to 'read only' - which will prevent them from being overwritten, but not from otherwise being corrupted.

    gmapprom.img is the 'built-in' Garmin map(s).

    MapSource and BaseCamp create a gmapsupp.img file. That is the only mapset you should be renaming. This new name needs to be 8 (or less) standard charcters with an .img extension. The 3D data is 'built-into' the vector map file and not in a seperate. It has not been reversed engineered, so is only available with a Garmin mapset (or one built with their expensive and tightly controlled software).

    problem loading maps to a new 62

    in GPS technology and devices

    Posted · Edited by snowfleurys

    Did you download/install/update the 62s software/firmware from the Garmin website? What was on my new OR300 was two versions out of date.

     

    Probably the AR topo from gpsfiledepot, as he mentiones that website in his first post.

     

    If I might ask - what does a 15 year old mapset offer that is not in one or more of the free mapsets currently available from gpsfiledepot and/or other websites?

    GPS start up time and inserted SD card speeds

    That is more likely a function of the massive amount of scaling that must occur to take map data and sort out what to display at those zoom levels to make something useful of it. Picture the process of sorting out what data must be discarded in those views.

     

    I do not think that is correct. When cgpsmapper compiles a .mp file to .img format it does one pass for each of the levels that the data is being defined at, and then combines it into the .img file. This creates a unique set of coordinates for each 'zoom display level range'. Note on the GPSr as you zoom in, the data will be 'enlarged', then the data will be displayed with more detail be it goes to a more detailed display level. At each 'zoom display level range' the GPSr is using that set of coordinaes which is defined to be used for that display zoom level; it does not have to discard anything, only scale it to the display window. Obviously at the more general display scale within any 'zoom display level range' more data will have to be scaled to displayed on the GPSr screen.

    Method of Adding Maps

    in GPS technology and devices

    Posted · Edited by snowfleurys

    Some of Garmin's mapsets are locked and some are not.

    If you are interested in one of there locked mapsets (i.e. CityNavigation, BlueCharts) and need to use the mapset on more than one GPSr or intend to replace the current GPSr soon - then the prerecorded Garmin card might be benificial.

    If you are interested in one of Garmin's unlocked mapsets (i.e. TOPO100k, and posts say their TOPO24k is also unlocked), it is generally better as you can select only some of a mapset to upload to the GPSr and can also add other mapsets to the micro memory card - it is not advisable to add additional mapset data to a Garmin prerecord card as it could damage the prerecorded mapset. If you had CN on a prerecorded card would would have to use the GPSr's internal memory to add additional mapsets (i.e. a contour line overlay mapset, etc.)

     

    Since you did not indicate any specific use for your OR it would be hard to say about specific mapsets; however, take a look at the free mapsets available on gpsfiledepot.com. You can 'preview' an area of your choice for some of Gasrmin's mapsets on their website.

     

    Some previous posters indicate Garmin has replaced a lost/damaged mapset, others say they have had to purchase an addition one.

    Multiple Topos

    Sounds like you may have selected quads/tiles/the entire state from the LA topo, then did the same for the MS topo, then had MapSource send them to your OR, then renamed the gmapsupp.img file to latopo.

     

    That wiki informnation is obviously incorrect. A few weeks ago I tested and posted that I put 17 individual mapsets on the micro memory card in my OR300, some 'normal' and some overlay/transparent. Each could be enabled/disabled individually and various combinations works as expected. This was in response to a post saying they thought the limit was 10 mapsets in internal memory and another 10 on the memory card.

    Garmin custom maps to DeLorme

    in GPS technology and devices

    Posted

    Since I started the post, I should answer the question. My "custom maps" are maps created by me, with my data. Therefore there is no issue with my distribution of them to another user.

     

    I use GPSMapEdit and CGPSMApper to create custom maps that Mapsource can read. From Mapsource I can load them to my Garmin GPS. I want to take that same information and create something similar for a DeLorme GPS unit.

    Each GPSr company has their own propriatary format for their data. I have not heard of any program which can convert the data of another. DeLorme sells a program to build the files their GPSrs can use. Since you have built your own files for Garmin GPSrs you could purchase their conversion program (was $300 4 years ago, but I think they lowered it to around $100) and also process the source data to their format.
