NASA ASTER Produced by Mr Purple
10m Contour lines generated from the NASA ASTER data and streams from
the LINZ data. The maps are transparent and should overlay the NZ OPEN
GPS maps if uploaded together to your GPSr.
The NASA global
digital elevation model is a product of NASA and METI. The original
data has a resolution of around 15 meters but has been over sampled to
10m to help guide the eye at close zoom levels. This results in some
spurious isolated contour lines particularly in flat areas and also has
a tendancy to smear out features smaller than 20m or so. The stream
data was obtained from www.Koordinates.com from the original LINZ data crown copywrite reserved.
