Anybody here adept at retrieving NED data from the National Map Seamless Server? I'm having a little trouble and need some help.

I’m trying to download some NED data from the Seamless Server and am unable to view the Request Summary page.

I’m on an Intel iMac running OS X 10.5.5. I have used both Safari 3.1.2 and Firefox 3.0.3. Popup’s are not blocked. I access the server at http://seamless.usgs.gov/index.php. Select US Data, zoom the map window to N. California. Set the download layer to 1” NED. Select the “Define Rectangular Download Area” button and draw a green rectangle around N. CA (roughly Oregon border to Bay Area, Nevada border to coast). A new blank window opens briefly followed by an error message saying the extract server is not responding.

Am I missing any steps here? I did this last week for the first time and got a request summary page with links to all the files I had selected for download, but now I get nothing.

Thanks,
Dave

Well, looks like I was trying to take too big a bite, although the system says I can select areas that large. If I select much smaller areas I seem to have better luck getting the download request page to open up. Its still frustratingly glitchy.

I've had that same problem. I have found that, for some reason, the NED server strongly prefers Windows computers. This is the main reason I just installed Windows on my Macbook. The NED server has never worked reliably for me in OSX (no matter what browser I try), but when I run in Windows it works fine in Firefox.

O, curse our Windows-dominated world!

I hate to be this cliche but... if we can get a man on the moon we ought to be able to get every website on the net to work equally well on a PC and a Mac (their both Intel chipsets for crysssake!). Rant off. : )

Hi Dave
I had downloaded 1/3 sec data for a small area for a trial and I was lucky to get it in the first go. Do let me know the extent and I will try it for you.

i've been using the seamless server for over a year now pretty regularly. but something's wrong with it lately.
it never used to be this slow as it is now...

I agree that the seamless server can be a pain. I have the 30m DEM in 1 degree tiles for the US except Alaska. If anyone wants I can make copies on DVD and send to you (would $12 US be reasonable? I think 6-8 DVD would cover the whole US).
Which UTM zones do you need? Inquire to graveldraw@hotmail.com

if your successful in getting the new download window, you can also change or "modify download request" and pick other layers to download without having to go back to the main page, didnt know if u saw that...
