Snag it and Google earth tips
Just playing with Snagit today trying to get an image to verify some field shots of a beach path.
What worked really well was using Google earth “measure Line” to draw a random line, then when using the screen capture, include the line and the pop up box with the distance. save it as a tiff, then insert the image to cad.. scale up so your line is the right length and move to your linework..
A neat little check and the image is MUCH smaller than the county aerial images that clog up the drawing.
I was trying to find out if you can get the images geo referenced right out of snagit or GE, but could not. Anyone else have a related or better tip??

Where’s the “like” button on this thing……?
Thanks Andy! I’m gonna’ try that.
why don’t you reduce the file size of the county images? downsample correctly and you will not lose the image clarity as much as a GE image. then use imageclip to only show the area you need.
or buy ram, lots and lots of ram and a new video card with lots and lots of ram.
okay, I’m listening.. how do you do that?
Tatuk. It’s free

Tip:
Do you need to downsample your MrSID Generation 3 images? Use the optimizer – it’s a quick process!
Let’s say you have images with a resolution of .5 meters per pixel and you wish to resample it to 2 meters per pixel:
Images > Add MrSID image to optimize (or press the optimize button)Add your image
Click the “More Optimize Options” button on the properties tab
Select the “Optimize Settings” tab
Select the “Resample image” checkbox and choose the level (in this case 4, to go from .5 to 2)
you can do the same thing by simply capturing the scale bar at the bottom of Google Earth, no need to use the measure tool to draw a line at a specified distance.
Photoshop er Lizardtech
I had Photoshop on my XP box that would downsample. I know there is a free program out there that will do it without resizing your image. Oh wait, the Lizardtech GeoViewer will do the GeoTiffs too, but the preset quality on the viewer is low. (Computers are not the only things that need more memory)
That Tatuk looks neat. I will try it out this evening. There may be the perfect answer for many.
As far as imaging tools in CAD, IMAGECLIP will let you reconfigure your frame.
Civil 3D will import a Google Earth image Geo Refrence

At the risk of self-promotion (and please forgive me if this is over the line), Carlson GIS can handle geo-referenced Google Earth images and the Esri ArcGIS On-Line Services with just a couple of mouse-clicks:

Ladd, the issue isn’t importing, but rather exporting from something like GE with the georeferencing data.
Thanks for the links, I’ll check out the videos when I get some time.

Down South, I have imported images in c3d that were georeferenced but the scale is always off and i have to tweak the image. Does yours come in to scale? If so how?
