along the Line. For an example, check out the ET Geowizards Easy Calculate
function Polyline_Get_Z_Midpoint. You'lld have to modify that one to pull
z values at set distances along the line and export them to a dbf or txt
file. Then bring these into excel for manipulation.</SPAN></FONT></DIV>

class=026144018-20012006>I did something similar for Jon Arthur on the SWFWMD
project. One point data set was more acurate than the others. What I
did was create a raster surface for both data sets. I then created a
gradiated buffer around the more acurate points. When a cell is not in the
buffer, only the value from the less accurate data is used. When a cell is
in the buffer, an average of both data sets is used. Since the buffer is
gradiated, the closer you get to the accurate feature, the higher the percentage
of the accurate data value is used. All done with raster calculator.
It ended up making mound features around the accurate points, I believe making
the buffer gradient a bezier curve helped. Just takes some playing to make
it look like what you want.</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=091083121-18012006>1. Is there a
way to export profile information from 3D Analyst to Excel? I can get a
profile drawing in a window, but it's useless. I would like to export the
profile data, so I can have more control over the input/output. I'm using
the NED and NHD.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN

<DIV><FONT face=Arial size=2><SPAN class=091083121-18012006>2. Can you
combine raster and vector data to create a new TIN? I have
some good surveyed elevation data that I want to merge with
not-so-good DEM elevation data to create a continuous surface representing the
best data available. Example: The survey data includes road
centerlines, edge of water, and some spot elevations, but nothing in
between. I want to use the DEM to fill in the gaps. Is this even
possible or recommended?</SPAN></FONT></DIV>
