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
