Header 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.
