Someone here was complaining about the lack of detail in some areas of Google Earth. I have the same complaint but came up with somewhat of a solution. Iceaxe posted on the Yahoo Canyons forum a link to a site with USGS topos and black and white satellite images of the entire state. I downloaded some of the images and tried my best to match them up with the crappy images on Google earth. They aren't perfectly lined up, but really close. I've tried multiple times to upload the .kmz files for Zion NP. They are just over 2 MB each, but I just get this message every time I try to attach one:

Upload Error: Could not upload Attachment to ./files/cogswell_point.kmz.

I'm sure all the Google Earth geeks would be interested in these files, any suggestions on how to get them to you all?

Do you mean, you're trying to upload that image to this forum? If that's the case, the filesize restriction is stopping you. There's a 256kb limit for images.

But, a ".kmz" file really isn't an image. It's just the G-Earth location tool. The thing about the kmz file is, they're not that big. I guess I'll have to mess around with it to see exactly what you are talking about.

It's a .kmz file that is just over 2 MB. The image is embedded in the .kmz file. If I double click on the .kmz file on my machine the satellite image comes up in Google earth exactly where I placed it and saved it. Try it, from Google Earth click "add", then "image overlay". Choose an image on your machine and it place it where ever you want, then it will show the name of the image in the places window on the left. Right click the name of the image and choose "Save As". It will save a .kmz file that will be around the same size as the image. Find the .kmz file on your machine and double click on it. That's the type of .kmz file I am trying to upload, it's not a place mark, but it just keeps giving me that error.

And for anyone interested here is the link I posted to the Yahoo group. This link will allow you to download all the USGS maps for the state of Utah.

Lots of other useful stuff on the site also.

And just for the record.... here is my favorite free mapping program http://jdmcox.com. Its called USAPhotoMaps.... great program.

Its archaic..... no pictures, no video, no HTML, no smiley faces, no avatars, no signatures......

......but worst of all......

They don't have the hot babes we got here :2thumbs:

Here are some images to give you an idea of what I did, hopefully I can get the .kmz files uploaded so you can all share in my labors.

Wow! Very cool! I didn't know you could do that.

I'm going to have to try that. I can immediately think of some areas that desperately need it, like the Green Valley Loop in St. George. Also, some of the Wind Rivers, WY.

Thanks, bro.

Shagg, you tha man. :hail2thechief: :hail2thechief:

I have got a lot of work to do! There's so many trails that I want to "fix" on the resolution. I only wish I had the time.

Here's the first one I tested it out on. It's the Green Valley Loop bike trail, just outside of St George.

Shaggy is the Google Earth masta.

Now we just need to get the upload problem figured out. We can spread the load by "fixing" areas and posting them here for everyone to download.

So are these B&W aerials projecting on the fly over Google Earth?
Does it have to be a special image file type to overlay?
Or do they all happen to come in the same projection to start with?

Google Earth was very smart to give it's users the ability to add images to it. GE knew that they would not have the best resolution on every spot (for the free version anyways).

So, you can take any image, and "paste" it ontop of the GE terrain. When doing this, there's an editting period that lets you "resize" the image to fit the area, and to also move it around a bit.

The 3D terrain, or the surface texture is still GE's, but if you find the same area and paste it there, it should match up pretty close. You could even paste a picture of yourself.

Yea it's pretty cool, lots of practical things you can do with it if you have the time. I did a "tour" of Choprock Canyon where it "flew" between photos embedded along spots in the canyon. I've seen the Arches NP map pasted over its actual location on Google Earth. You could paste topo maps over areas and have a 3D view of them. Pretty cool stuff, shows the potential of this program as it evolves.

So, when will the Google Earth porn start showing up then? :naughty:

The large squirrel is a prophecy to the people of Ogden. Cover yer nuts!

Actually, this whole time I've been saying "squirrel", when it's clearly a chipmunk.

Ogden can rest in peace now.

We do similar image overlays here at work, but we need to know the projections. I make our own hi resolution 3D terrain models of river corridors. Then we overlay our own orthophotos tha we had flown, or use DOQQs from the state.

OK, I got it to work over on the Google Earth board. It only lets you upload one file at a time, so I put each file in a seprate message (pt 1,2,3,4 etc...) Download them all and it should cover the whole park. I don't know if you need to join the forum in order to download them. Just make sure when you close Google Earth and it asks if you want to save the places in your temporary folder, you choose yes, otherwise you will have to downlaod the files again to view them. Another thing, if the B&W image doesn't show up, look at temporary places on the left and make sure the boxes under it are checked.
