Need help reading a IMG data file for elevation data

Mynight · 31 Mar 2015 at 16:50

Already had a quick look and the closest I came up with was;

http://cms.sbcounty.gov/gis/FTPServices.aspx

If the government site doesn't have it chances are it isn't online yet.

Stupidly uses FTP so I've requested access to confirm if its covered.

Edit: Meh 18kbs for a 200mb file

. I dont want to help that much

.

Here are the User and Password.

User Name = gisftp

Password= 1sbcftp1

If you are going to use a FTP application like Filezilla, use the following settings:

Host = gis1.sbcounty.gov

Protocol = FTP - File Transfer Protocol

Encryption = Use Plain FTP

Logon Type = Normal

User = gis1.sbcounty.gov|gisftp

Password= 1sbcftp1

Transfer Mode = Passive

If you want to do it yourself.

downloaded filezilla, no idea how to work it tho but im sure ill figure this out haha

Mynight · 31 Mar 2015 at 17:44

Lol its fairly simple dont worry

.

All a learning curve.

IceShock · 31 Mar 2015 at 17:47

just keeps saying error could not connect.

whats this thing do iv actually no idea what im doin here

haha or what it is supposed to do.

Mynight · 31 Mar 2015 at 17:53

alright;

download;
http://www.coreftp.com/download/coreftplite.exe

install then open :eek:

.

gis1.sbcounty.gov - in host/ip/url
gisftp - in hostname
1sbcftp1 - in password

Dont touch anything else as it should be right already and click connect. On the right hand side is the files on the server on the left if your system folders.

Find the directory on the left you want to save them in and find the right file on the right, right click it and "download".

IceShock · 31 Mar 2015 at 17:58

Ooo sweet, its downloading cheers

any idea which one I need to download? jeeeeze 20kb/s

so far im just downloadin the lot but this will take weeks lol

Mynight · 31 Mar 2015 at 18:00

Yeah they really splashed out on their broadband

.

Honestly dont know. All I know is its touted as GIS data which hopefully includes topographical.

Shame this sort of thing isn't on P2P. Could have downloaded all 600mb by now.

IceShock · 31 Mar 2015 at 18:03

haha I know, and okay cheers dude

19 hrs it will take. damn

56k dial up eat ya heart out

You're using the height maps to make displacement maps for subdivided planes to easily reproduce the terrain?

Mynight · 31 Mar 2015 at 18:13

Ergh found a list of whats supposed to be in there and annoyingly the best seems to be a 10M DEM.

Lol I offered him 40, he wont share!

also, you got the link for 1/3 arc sec? idealy need 1/9 but ill take any I can get of this area right now

haha

Mynight · 31 Mar 2015 at 18:43

The 1/3 arcs are on the site you linked to in first post. When you hit download select the top option drop the rectangle and it gives you a load of choices.

Now for £40 I could be persuaded to give you the secret link I have yet to find

The downloads from that ftp thing will be done in 1 hr 20 mins btw, dno where I got 19 hrs from I calculated that wrong

Btw the area was scanned in 2005 if that helps, that's what Iv been told when they scanned it cause of the earthquake

Mynight · 31 Mar 2015 at 19:13

Yeah that was for scanning the fault lines in Andreas in 2003 they caught some of bernardino.

Back to google I go. If I haven't hit gold in the next 30 mins I'll have to give up for now sorry.
