Importing ChartTiff DRGs
/ Geos and
NEDs / DEMs into PLS-CADD
Power Line Systems has
developed a Tech Note describing the how in import
ChartTiff Geo's and NEDs / DEMs into PLS-CADD.
here to go to PLS-CADD TechNote
The following is a quote
from the Tech Note:
this TechNote was first developed in the summer of 2000, the USGS
has undergone many changes in their data formats and sources. As a
consequence, they made previous conversion programs obsolete and
more difficult to use in practice. For these reasons, we now
recommend that you obtain your USGS data in a readily used format at
a minimal cost from ChartTiff. The rest of this TechNote will
explain how to use ChartTiff's data, as it is much easier to use.
The folks at ChartTiff have been a big help to us and have even
provided a download format that essentially imports directly into
PLS-CADD. We would highly recommend that you support them and if
they ask, please tell them that Power Line Systems recommended them.
At the price of $3 per quad sheet for both a collarless DRG and a
full NED/DEM, ready to be imported into PLS-CADD and available in the
coordinate system of your choice, this is a no-brainer."
