+BrianRTS Posted June 22, 2005 Share Posted June 22, 2005 I just picked up a Legend and im debating which Mapsource cd to get.. from what I can tell metroguide and city select are the same save for the autorouting which the legend doesnt support. My question is how many maps (sections?) does 8meg hold? In my case I live in Long Islans NY so id like to get the majority of the island and maybe NYC so I can start finding some caches. Thanks Quote Link to comment
Neo_Geo Posted June 22, 2005 Share Posted June 22, 2005 The following info is based on older version 5 MetroGuide maps. Version 6 is now current but 7 is expected to be released sometime this summer. I would expect the newer versions to contain a little more data than the older version. Still, it should give you a pretty good idea of what you're dealing with. The Legend's 8MB is a little bit lean for MetroGuide maps in the big city. The 8MB will hold the eastern 2/3 of Long Island - OR - the western 1/3 of Long Island. The closer to Manhattan, the higher the population density and thus the more map memory is eaten up by Points of Interest (POI) data. The way Manhattan itself is divided up into 4 sections, you will only get 2 of those sections into the Legend at any given time. It's disappointing, but the MetroGuide maps really are great in providing address lookup capability as well as searching for various businesses and attractions. Quote Link to comment
+Hi-Ho Silver Posted June 22, 2005 Share Posted June 22, 2005 From responses I've read in newsgroups, it is possible to cram more map info into the Legend if you are willing to live without certain types of POI's. If you use Google Groups to search for the thread "US model Etrex Legend in Euro Backpacking trip", you'll find some comments about the methods. Here are some of the tips from the thread--- From one post:--- | >| I've played around with uploading to the Legend with sendmap20, which | >| drops a lot of proprietary data when uploading. I can get twice the | >| maps into the legend that way, with no loss of useful data *to me*. | >| | >| sendmap20 is part of the cgpsmapper thingy. In response to the above, Jean wrote--- >>> What data do you lose when loading the Legend with sendmap20?

Then recompile to .img with >>cgpsmapper and upload. then Keith Sheppard stated--- Actually there is a way with a bit of extra software (watch out, there's a plug coming because I happen to be the author of such a package). Once you have used cgpsmapper to "reverse compile" your map into a .mp file, you can then load that into a mapping application. Let's see if I can think of one... I know, how about my MapMan (free download from http://homepages.tesco.net/~Keith.Sheppard/MapMan.htm). Having loaded your map into MapMan, click on the Edit menu and choose "Map Item". You will be shown a scrollable list of all items in your map. There are various tools to select map items by type and/or string match and you can then delete selected items. Having got rid of the dross, click on the Export menu and choose "Digital Map". Your pruned map will then be exported to a new .mp file and, optionally, recompiled. >>I can't tell what's missing; I had heard it was phone numbers and >>addresses of POIs, etc, but I haven't looked because I don't look at >>POI stuff much. I think it depends what version of cGPSMapper you are using. I seem to recall that the freeware version discards all the autorouting data and address details - which include the phone and address details you mentioned. I haven't tried any of the above method(s), but it seems like a worthwhile thing to test out. Hi-Ho Silver Quote Link to comment
+seether106 Posted June 22, 2005 Share Posted June 22, 2005 If you use the garmin mapsourse products; City Select = a small portion of Long Island into the 8mg, about 1/4 of it. Topo = all of long Island and a nice chunk of NY. City Select has street addresses, gas stations, resturants, shopping and lots of other POIs. You cannont select which ones you want to download and which ones you don't Topo - doesn't have side street names. You can't search by address and about the only POI data you get are schools, cemetaries, and a few others. It's the POI data that takes up all the memory and with mapsource there isn't an option not to download them.
