I checked out this site the other day and was able to print google aerial maps for Free.

Most of the sites I had tried wanted a fee to print.

www.forestasyst.org Now if google would just update the imagery, South Georgia area is about 4 years old.

That was fun

The soil map is very good

I took the time to use google earth and photo shop last year to piece together and create a file that I hope to take to a big print shop one day. Its a high resolution arial photos of my land and the land of interest around it. It should print out a wall size photo if I wanted it to. The second photo, you can see my driveway off south side of the north road just to the left of the pavement color change. If you go straight south until you get to the north edge of the power line, the black spot is the roof of my tower blind.

A bit confusing on the description, but an old Defense Mapping School (terrain analysis) honor graduate can pick it out from the contextual info.

. I love aerial imagery, could spend hours studying, even more intriging in urban settings AND looking for concealed threats

Your tower reads as a shadow opposite the real tree shadow across the power line due south.

Hmmm
Shadows look right to me...sun in the south.

Top of "map" is north.

Yup, watching TOOOOO many little ones will make you a little batty.

corrected my incorrect statemant, Ironwood

The sun is almost dead south as on my full size image here I can see the unmistakable shadows cast by the power poles. the line starts in the center of the power line and goes north. The poles are in the center so its easy to determine the direction. I suppose with enough data, a guy could almost figure out what time of day and what time of year the photo was taken. Probably the only data you would need outside of what is gathered in the photo, would be the height of the poles.

That's my friend Lou's driveway going to the north of the North Road. It's about 1/2 mile long and cuts through his front ponds and ends at his house on the north side of the Ponds.

Pole height can be calculated from the next photo in the series, to create a steroscopic image, and w/ a parlax bar (sic, available from Gempler's) you can come close. A larger object makes it easier (building, pile of gravel, hill, etc..). The pole top is a tough target but certainly tree height can be done this way.

I only use google as a last resort now. Our county went to some kind of mapping thing in 2006 and the photos are updated once a year. You can get property lines, zoning, owners, and do a lot of cool stuff with the built in tools...like the measuring wheel. Most counties are doing the same as most of the dollars are coming from the Fed.

I got some nice printed photos out of the Corp of Engineers a few months ago. USDA might also help if ya talk nice.

Took a screen shot of my place to show some of the cool tools available.

Larry,

Those are generall refered to as GIS systems.

Tim L · « **Reply #11 on:** January 04, 2009, 04:24:36 pm »

how old are the images ?

Ironwood · « **Reply #12 on:** January 04, 2009, 05:05:52 pm »

It will/ should vary greatly. The GIS systems are patchey as are the various co.'s that provide the info. to the carriers we use here. My google earth was a couple years old as I could see my 8000lb forklift sitting in my drive. You will need to study the photos a bit if that info is not provided by the listing co. (in my case google). At my place I can date it by what is laying around

. Many counties do frequent fly overs to get code enforcement issues sighted. I believe my Township does that on a bi-annual basis (every two), it will vary as some townships have varying resources ($$$). Larry, your photo looks like a plane platform, not satellite as with many "google services". The definition is too great for anything other than top shelf military satellite, unavailable to the public (in my dated opinion)

I've always wondered this....how do you take the screen shot to post it like that?

Larry · « **Reply #14 on:** January 06, 2009, 08:21:50 pm »

Hit the Print Screen button on the keyboard...go to Paint (or your favorite image software) and paste. Save as a jpeg so it can be posted here. I fergit most times and have to do a google to refresh my memory...happens when ya hit the big 60. So..."Don't ever grow up"

beenthere · « **Reply #15 on:** January 06, 2009, 11:58:06 pm »

Hmmm?
I usually press Alt + print screen to capture, and then paste to Paint. Then cut out the peripherals and cut/paste, save to .jpg or print. Will try it without the Alt button to see how that goes.

Works just fine without the Alt key pressed. Always learning something new.

Yet another GIS thread

This is from data downloaded off our provincial government website. I generated the contours with 20 meter (major) and 2 meter (minor) intervals. I can adjust the smoothing, but went with no smoothing. I have also generated my own contours with the GPS, and collected X,Y,Z positions. I put a 30 meter wide buffer along one of the streams. The area on the left edge of the screen is in the State of Maine near Mars Hill. Yellow numbers are property ID numbers (PID) we see on our tax bills.

wow, who would think that that button on the keyboard that says "print screen" is the one you use to print the screen....absolutely amazing what we can do these days....

i guess if i opened my eyes i would have seen that earlier, thanks...

Piston
I can remember the time when hitting the Print Screen button actually caused the printing of the screen to the printer. Not sure what is different, other than so many more options. And maybe it is just configuration of the computer. More choices when it gets to "Paint", as can block out areas of interest to capture.

Oh man, Fortran 77, print screen and tractor feed paper jams. The good old days.
