Talking to our GIS department (ESRI users), they say that
ECW is a standard aerial format and "fallen out of
favor...to JPEG2000" is not an accurate statement.

Anyway, what is strange is that when you load the same image
in ArcMap, the zone is displayed as "NAD_1983_UTM_Zone_14N",
not "NAD83 NUTM14".

I don't know where Raster Design is getting "NAD83 NUTM14" from.

Our image vendor will be here in a couple of weeks.
Hopefully we can find out some more info.

I believe you've misunderstood. I'm not talking about current usage
in the GIS community. I explicitly referred to ER Mapper, the owner
of the ECW format. All of their latest compression tools and libraries
are focused on JPEG2000 (with ECW has an afterthought).
But you don't need to take my word for it... just go to their website
and see for yourself.

Ok, be that as it may.... What ER Mapper thinks or does, I
don't really care about.

What we do care about is being able to easily import aerial
images into AutoCAD.

Using ArcMap, it's a simple drag/drop from Windows Explorer.
AutoCAD MAP can't do it at all, and using Raster Design, the
user must know the image coordinate system.

My whole point in this thread is why can't an Autodesk
product read the coordinate system from the image and place
it accordingly. I shouldn't have to care about the image
format, file extension, etc., etc.

Thanks.

Matt:

For what its worth, JPEG2000 is not the primary focus of ER Mapper. As a long time user of the ER Mapper software, I have observed that the ECW format is just as well supported in the ER Mapper software as is the JPEG2000 format. Considering that applications able to write JPEG2000 images rarely do so in a standardized way, I argue that the JPEG2000 format is not quite where it could be and other formats are more often usable.

My concern is not so much the JPEG2000 verses ECW issue, but rather why Autodesk's Civil 3d/Map and Raster Design (v.2008) products poorly support the ECW format. Both the Data Connect and Raster Design Image Insert commands have problems in handling ECW format images. At the very least, Autodesk could provide a realistic time estimate on when the problems with ECW support will be resolved, or even if there is a plan to correct these problems.

Thanks for your time,
