How Much Will 1 Meg Hold ?

Recommended Posts

Guest mojo

The etrex legend has 8 meg of memory for downloadable data, the Vista has 24. Is 8 meg enough for a whole state map or topo?

8 meg is enough for my map 330 and has most of utah in it. Don't have topo for it so don't know. Lee

Depends on the state, of couse. Texas? Nope.

 

And in some cases, you should be able to load an entire state, but the state may be split between 2 or more regions.

You can use three kinds of maps.

 

Metroguide is for a large region. Each map is about 6 to 7 megs.

 

Roads and Recreation. Each county has a map usually about 300 k

 

Topo USA

They are for areas.

 

I used to have a GPS III+ which held 1.4 megs. That worked, but for every trip you had to load maps.

 

I got the Vista now and love it. 8 megs is a lot of memory and would likely be enough, but I still reomend the Vista.

So, if I was going cross country with the legend I better bring a laptop and software?

and you say the road and rec software loads by county?

i have the etrex vista and the mapsource topo maps and 24 meg will take almost the whole state of utah, all but 6, 7.5 minute quads before i get a "may not fit" message.

I have the 1.4m 3+ and topo usa. I can usually get 4-6 quads loaded. Never had less then 4 which is a good thing since where you want to go might be on the corner of the 4 (so you need all 4). IIRC streets and trips have smaller file sizes so you should be able to load more. 8 m would be nice (when I got this I thought that 1.4 was a little stingy) as it wouldn't require reloading segments.

 

Doing a quick check CT needs 7.44m for the entire state including overspill. TN takes 32mb. don't have the topo west handy.

That depends on how much detail you want while on the trip. The basemap has the major highways, and that remains even if you load the new maps on top of it (at least it has with mine.) You can just load up the detailed maps for your destination. If you want the detailed maps all the way, then yes you should probably take the laptop along.

Most maps cover one county. If the county covers a lot of area, it's sometimes split up into two separate maps.

 

One problem I've had is that some maps are out of date, and others are very current, and there's not any obvious way to tell which maps are out of date (no date of editing, etc.)
