How often are the Google Maps satellite images updated?

Q. We've done quite a bit of renovations on our little farm and I'm curious when we'll get to see a change in the satellite view on Google Maps or Google Earth.

A. Google purchases the images from many different sources. Most of the images are purchased second hand - basically the images are not taken for the sole purpose of supplying them to Google. Most of the images are taken for completely different reasons and released to the public or sold to Google for extra profit.

Suggestion - your local government agency (county or city) should have a Geographic Information Sytems (GIS) department or division. They could be a great source of aerial photography.

I work for my local GIS division and we have images at 6" resolution taken in spring of 2008, 2007, 2006, 2003, 2001, and 1997.

Check with your local government - they will be the best source for updated imagery.

How I get snaps shorts from google earth to get a map for a specific area?
Q. I want to make a map and print that for a specific area in high resolution from google earth. But my problem is that I can't joined the snaps properly in Photoshop for getting the wright map for a specific area. Is there any software for taking the snap shorts from google earth and joined them all to generate the right map for that area in high resoulution.

A. sorry, but there is no software to take a snapshot from google earth, but you can do so by other way.

1) you can [b] print screen the page by pressing the print screen button of your keyboard [/b],

2) then paste it in mspaint and cut out the map and paste in other paint.

3)then slide the map in google earth and again repeate the 1st step.

4) after that paste that map in other paint i which you had pasted earlier after cutting.

5) and slide that to join both maps to a single in paint.

by this way you can create a whole map.

ya, it will take some time but by this way you can get your whole map clear.

How can i find the coordinates of a point on the map ?
Q. I have tried Yahoo map and Google earth for that, but no result. Please guide me in finding a software or a website that can give me the coordinates of a point on the street size map.

A. If you open Google Earth and put the pointer on a certain point you'll immediately get its coordinates in the low left corner of the map!
