pre-release demos for 9.2 ESRI touched on the 2 point limit introduced with 9.2.
Their logic was that in theory CAD files are normally more accurate at least
relative to the features inside the drawing than GIS data. So to maintain the
overall integratity of the drawing they do not allow skewing.</FONT></DIV>

style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">Hi all, thanks for
everyone’s input and offer of assistance last week on various approaches to
referencing a large TIFF file that I was working with. Here’s the sum and
a couple other comments on spatial referencing. Would love to hear from
some experienced users on best practices for working with CAD data.
</SPAN></FONT></P>

<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">Several folks had
suggested ArcScan to get around the size limit, however, at the present time I
only had access to ArcView 9.2 with only a demo version of spatial
analyst. Rescanning at this point was not an option. I tried to clip
out aoi from the TIFF but that process was still running after several hours, so
I had to try an alternative method. I finally used the spatial adjustment
tool, as Tripp had suggested, to get the CAD files close and then manually
digitized/edited the rest also using the georeferenced TIFF as an additional
resource. Here’s some issues I had with using the spatial adjustment tool
and the georeference tools for CAD files. </SPAN></FONT></P>

<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">I exported the line
drawing from the CAD file to a shapefile, then set several displacement links
with the tool. Transform from and to links didn’t seem to yield a very
good RMS even with >6 GCP and I had fairly good intersections and building
corners to work with from a reliable doqq. After doing a transformation
project, I tried to rubber sheet a couple selected areas but got poor results
from that attempt. Is there a trick to this? I have not used this tool
before.</SPAN></FONT></P>

<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">I found with
georeferencing the CAD file, the scale and shift tools don’t allow a
preview-as-you-go while performing the shift, so it’s impossible to see how far
you are actually scaling or moving the drawing. I’ve seen the demonstrations
work well but the boundary ‘guide box’ didn’t seem to show up for me.
Anyone know why they restrict 9.2 to 2 gcp A coworker forwarded this lab
to me from the ESRI forum – maybe this is the way to go next time (see
attached). Thanks and hope to see everyone at SERUG next week.

<P class=MsoNormal><FONT face=Arial size=3><SPAN
style="FONT-SIZE: 12pt; FONT-FAMILY: Arial">Have you tried using ArcScan? I do
not think it has a size limit. Other than that you will need to reduce the
actual file size and not through compression. Compression only reduces the
storage size. The image must decompress into memory when viewed bring it back to
it's original size or at least that is the way I understand it. So you would
need to reduce your resolution, trim the image or some combination of
both.</SPAN></FONT></P></DIV>

received a large TIFF of an old scanned map that is approx. 450mb. I
georeferenced it and tried to convert to vector for further clean-up but
spatial analyst is giving me an ‘over the max 2GB’ error. I tried a
lossee compression because I just need the boundaries from the map but this
did not help and took over 2 hours to process. Can anyone give me a
suggestion? Thanks! Kristal</SPAN></FONT></P>
