Map data is collected from multiple sources, providing full state-by-state coverage.
For further information, see The National Map home page. The most recent Huntview Plus Maps by Garmin, featuring exclusive BirdsEye Satellite Imagery and 1:24K scale TOPO mapping, these preloaded microSD cards offer a seamless hunting map solution for Garmin handheld GPS devices. In addition to topographic quadrangles, the USGS publishes many other kinds of geospatial data and imagery. The Historical Topographic Map Collection (HTMC) is a set of scanned images of USGS topographic quadrangle maps originally published as paper documents in the period 1884-2006.īoth US Topo and HTMC maps can be downloaded free of charge through several USGS interfaces. These are modeled on the legacy 7.5-minute maps, but are mass-produced from GIS databases and published as digital documents.Ģ. US Topo is the current topographic map series. Today, USGS topographic quadrangle maps are divided into two product types:ġ. At about the same time, a separate project was started to scan the entire historic library of traditional topographic maps. Named “US Topo,” these maps are modeled on the 7.5-minute series, but are derived from GIS data. This is weird, Garmins Canadian website does not list the Montana t (topo maps) but only the regular 610 / 680 versions which as far as I know do not contain topo maps.
In 2009, a new USGS quadrangle topographic map series was defined. The last printed USGS topographic maps were published in 2006. Map revision continued, though in decreasing quantities, through the 1990s. TOPO 24K maps feature our highest level of topographic detail (1:24,000 scale), complete with terrain contours, searchable points of interest and.

We recommend that you use a compatible SD card when installing the maps with your device to receive the largest map region possible.
The 7.5-minute series was declared complete in 1992, and at that time was the only uniform map series that covered the United States in considerable detail. During a map update, Garmin Express may prompt you to install a map region to your device. Similar maps at varying scales were produced during the same time period for Alaska, Hawaii, and US Territories. From approximately 1947 to 1992, more than 55,000 7.5-minute maps were made to cover the 48 conterminous states. The best known USGS maps are the 1:24,000-scale topographic maps, also known as 7.5-minute quadrangles.
If you take a few minutes to read those turtorials you likely will have your questions answered.The USGS was entrusted with the responsibility for mapping the country in 1879 and has been the primary civilian mapping agency of the United States ever since. Sounds like you did not read the tutrials I gave you a link for in post 11. Questions: When you transfer to MapSource is it 'cutting' the map from the GPS or 'copying' it? The reason I ask is, if it's just copying it and I create this new map wouldn't technically mean I would have 3 maps on the GPS when I'm done? I have a 4gb micro SD card installed and both maps are over 1.5 gb leaving a limited amount of space for a 3rd map.
Then I can select the tiles for each map that I actually want and can transfer it back to the 60CSx? Once downloaded, 'transfer > receive from device' from MapSource which should technically copy the map file to my hard drive. ĭownload one map at a time from the Garmin site. Since I'm new to MapSource as well let me see if my plan matches up with your advice. Hit "menu" again and you'll see selections for toggling "show" or "hide" for each layer of the map. You can select what layers of the map you want to see by hitting "menu" and selecting "map setup". This version is not locked so it can be used in mulitple units that are compatible. Send the whole shebang to the 60CSx (it will take a LONG time) and then go to the map page on the unit when it finishes loading. Topographic detail of Washington and Oregon. 2025 tiles is the limit for a single map and, I believe, 4gb is the max size. Keep an eye on the lower left corner of the screen as that will tell you the current size of the map and number of tiles selected. As previously said, just open the maps you want in Mapsource and highlight the selected areas on each individual map (TOPO, City Navigator, etc).
