| yes, I have used it in the past. the only thing about their site is that you have to download parcels. you do not define the area you want. If your plot happens to be contained all in one parcel great. however, I have had time where I had to download 3 or 4 to get the entire plot. but it still works very well. 3dem allows you to group together dems and open them together. from there you can get what you need. make sure you look at each text file to make sure you see what lat and lon the dem includes. you must know the name of the county in which the course resides and then each county is broken into smaller pieces. as far as I remember, that is all there is to it. it sounds like more work than it really is, but at the same time I still use the seamless site because it is just easier.the real nice thing about the geo community site is that you download USGA DEMS which are already in the correct UTM ellipsoid, so when you get to 3dem there is no need to convert and then see the landscape twist on you - lol. AND you can only get US data from the site. It is a good resource for those looking for 10 meter dems for the US. |

Cool Steve, I will try it. I found the County then got confused when it listed the areas.
Do I still get the orthoimagary from the Seamless site? The Homeboy Tut. for the seamless site said something about cropping the 2 together if you use the geo site? Do you know how thats done?
Thanks |

I always use Seamless, the orthoimage are good and has different types off it.
If the orthoimage is to big insize, or they are in 2 seperate files, i download the NAIP ortho.
Alot smaller in size, but still good to use.
If you still want to combine the 2 images, i open up photoshop, an start a new file.
the size is something about 12000 by 12000, this is gonne give you enough space to PAste your images in.
Open your images,Select them, copy and paste them in your new file.
Do the same whit the other image, now match to images togheter, and merge the 2 layer.
Then Control+A to select them, then control+c, make a new file, and use the size that the new file has given you.
Paste the image in your new file and flatten the image.
Now you have one image.
Goodluck
Ronbrug

Well, I know I have used multiple dems from the geocomm site along with 3dem. When you pick the file to open just pick the multiples. I think once, I connected 4 together and then when they opened I found that one of them was not connected to the other 3. What resulted was a hole where I thought it would go but it still attached the 4th piece where it would naturally go.
I think the only thing to make sure is that all the files are the same type. For example, all the files from geocomm are downloaded in tar.gz format, which is known as USGS DEM, while the files from the seamless site are downloaded (;by me, anyway) in geotiff format. I dont believe you can combine files of different types in 3dem. So as long as they are the same file types, you should be able to combine them. You just have to choose the multiple files at the same time. If they are in different folders on your hard drive you cannot do it. Once a dem is open in 3dem you cannot add more to it, you must open them at the same time.
On the seamless site there is no need to get multiple files. They allow up to 250 megs per file and I have never downloaded anything more than 3 or 4 megs in size from there. The files at the geocomm site are pre-made chunks. You locate them by state, then county and finally area. The problem is, the chunks rarely contain the course all inside one chunk, and that is why you need to download multiples. I rarely use the geocomm site anymore for that reason, although it is a good alternative when the seamless site is down.

Thanks guys, I'm gonna try it all out this weekend, hopefully my course will be in one block. If not i'll be sending you a PM Steve : )
Ron is that method you described above to link 2 ned or 2 ortho files together? What I was really curious about is how will I line up the Ned from geocomm and the ortho from seamless? I have a great overhead from seamless but the 30m dem was pathetic for the course I'm trying to do..
If your around this weekend, please drop by, I'll probably have more questions....
thanks again
