Downloading and Using DEM for Watershed and Stream Delineation

I decided to start the lab for this week since I had some free time...this is what I got though so far.

First I stated by going to the site http://seamless.usgs.gov/ the above is what I saw.  As I read the directions I did noticed that the second step should of read as follows...

2. At the left hand side of the Welcome Page click on "Seamless Viewer" under the tools to Access Data.

When I followed the revised directions for number two, I saw the above :-)

I decided to zoom into the LA area, because I am planning to go to the National Planning Conference in April, so I wanted to get a lay of the land.

When selecting the area to down load (step #6), I saw the above. 

Note: The directions on the word document should read "left" instead of "right".

After I created a rectangle around the area I wish to download I saw the above.  I waited 15 mins and it still has not downloaded yet.  I think I need to pick a smaller area.



I zoomed in a little tighter (the above image), and I was able to download the info now :-)

Dang! I have to reprojected the raster :-I

Above is how I reprojected the raster.

I think I am done for today, see you all on the flip side :-D

Terrain Analysis - Assignment Section 1

This is the DEM (that was downloaded from the CGI website) of the Bay County located in the great state of Michigan!   

After running the "slope tool" found by flowing this path (Acr tool box>3D Analyst tools>Raster Surface>Slope) I ended up with the above results.

After running the "aspect tool" found by flowing this path (Acr tool box>3D Analyst tools>Raster Surface>aspect) I ended up with the above results.

After running the "hill shade tool" found by flowing this path (Acr tool box>3D Analyst tools>Raster Surface>hill shade) I ended up with the above results.

After running the "curvature tool" found by flowing this path (Acr tool box>3D Analyst tools>Raster Surface>curvature) I ended up with the above results.

And finally After running the "raster to tin tool" found by flowing this path  (Acr tool box>Conversions>From Raster>Raster to Tin) I ended up with the above results.

So far I am on the right track....now i just need to put these maps on some paper :-)
