We find the ECW compression utility to be the one
the best mapping tool innovation to come along in a while.
We've presently starting a forest inventory
mapping project for which we will be producing over 2000 orthophotos using PCI
OrthoEngine. The ortho outputs are produced in tif/twf format
which are then compressed at 1:20 using the FREE ECW compression utility.
The results go from 20 meg to under 1meg per photo.
We made accuracy/quality checks. The results are
more then acceptable.
Unfortunately MapInfo does not read the geocoded
information within the ECW. So re-registering 2000 ECW files within MapInfo was
out of the question.
Can anyone confirm this? We also tried the
MapImagery add-on without any luck.
Also because MapInfo does not offer Stream Mode
Digitizing we had to look at using ArcView which allows full stream mode
digitzing capabilities and automatic snapping features. Oh yes, Arcview also
reads the geocoded information from the ECW file like a
charm.
ArcView also can curve text along features. But
that is another issue.
