Six or less should be able to answer this.
What are the number of segments and total file size for each of Garmin's 6 24k topo DVD?
West
Southwest
North Central
South Central
Northeast
Southeast
West=1814=3.83GB
Thanks Indrid.
Only a 1/6 sample, but perhaps 10,900 segments and 23Gb. Any idea how much of the size is used by the vector data and how much by the DEM. I expect they load as one.
