Google Earth

by ice_bear_joe / April 12, 2008 8:42 AM PDT

I like to Google Earth to look at some of the old places I visited over the last 60 yrs and see the changes.
Great program and could really be good if kids used it,they could learn a lot about other countries.
I just would like it if focus up close was better.
Is it my computer or just the google quality.
Could some of you have a look and let me know of a possible way to improve it.

About some of the big fires that are set -- whether or not authorities could use Google or something similar to figure out what happened to cause the fire, or if someone set it, maybe they could follow the car or whatever from where it was set. Just a thought. I realize not all areas are covered as well.

I doubt it's possible ...

on either count.

The resolution available for Google Earth is not all that good for most of the earth, although it does seem to be improving with time.

I doubt that the service would be useful for IDing criminals except in unusual circumstances because it is nowhere near to real time coverage. Some of the pictures they display are from several (>10 at a guess) years ago. At least that is my impression from the view they had of my neighborhood until a few months ago. It appears that it has been updated recently, but I noted that the updated image is still at least a couple of years old since it does not include a road that has been around for at least 2 years.

Whether the underlying satellite technology that Google uses could produce higher resolution useful for both IDing criminals and for determining car models ... I do not know.

In the bottom right corner of your photo, Eye Altitude is 3418 ft.. If you use the sliding scale on the top right you can decrease your Eye Altitude and get a better view of objects on the ground.

After I get to about 2500' Eye Altitude I start to lose focus on the 2 yellow vehicles, 1 white vehicle and 2 planes bottom right.

To be able to tell the make? Not likely

From what I've seen of the Google mapping

it's like a patchwork quilt with some pieces showing excellent detail and others being lesser quality. It must have something to do with factors such as what equipment was used, how high up it was and what kind of atmospheric conditions existed at the time. I've noticed that larger cities in the US southwest where the climate is drier (try Phoenix Ariz. for example) will be quite good. High humidity areas won't be so great. As well, those areas where there's nothing much to see but trees or prairie don't seem to get much attention. I have to wonder if the map is a continuous work in progress where sections will be replaced with higher quality images as they become available.

It's clearly a work in progress ...
by Bill Osler / April 12, 2008 12:52 PM PDT

There are a lot of places where if you zoom out a bit you can see the variations in contrast/exposure/resolution in various places fairly clearly.

For example, if you go to 15

Guess I'm getting as good as can be expected.
Still some good sites to visit.

Sometimes you can get better images elsewhere ...

For my neighborhood the county maintains a GIS server service that includes very high resolution aerial photographs rather than than low res photos Google Earth uses. That availability obviously varies from place to place.
You can also check out Flash Earth which includes options to view maps/photos from various sources. Sometimes one of the sources provides better detail than the others.

i think that resolution is not fine for the earth so that its understood that it may be improve with the passage of the time...but the service of the Google is the very best because on a net we can see everything via a Google earth which is the beneficial for everyone.it also shows the road of the place.
