The Oregon Topo map series is free a set of
topographic GPS
maps for selected regions of the state of Oregon, currently covering
the Portland Metro and Astoria/Warrenton areas. These maps are built
from some of the
most modern and detailed map data available, providing land contour
and water features that are comparable to USGS 1:24k topographic
quads. Selected areas include current data for roads and parks. These maps are currently available for Garmin
GPS units only. |
