Why is Indiana's Google Map satellite imagery so thorough?

November 8, 2005 1:57 PM

Google Map satellite imagery filter: On Google maps, why does the state of Indiana seem to be so entirely scanned at highest resolution, when just about every other "place" on the map seems to just have high resolution scanning in heavily populated areas? What makes Hoosiers so special (to Google Maps, anyways)?

Within the IN state borders, you can just about click anywhere and zoom in to the highest resolution. Just outside Indiana (say, Illinois, Michigan, Ohio, etc.), you're chances are MUCH greater that clicking randomly gets you "We're sorry, but we don't have imagery at this zoom level for this region. Try zooming out for a broader look." Is there something militarily ominous about corn fields that Americans are unaware of?

Great question... I've wondered the exact same thing.

My friend lives in Owosso, MI (read: the middle of nowhere) and the area immediately surrounding her house is hi-res; half a mile away, though, there's nothing.

I think that Google plans to make everything hi-def eventually, and they just had to start somewhere (maybe with where their employees/friends live?).

Response by poster: See, I'm also aware that Google, the company, "borrows" the satelitte imagery and they just provide a nice interface to it. I'm also aware that the high resolution areas are probably hand-picked by the satellite owners/controllers for specific reasons. The satellite images "are taken from a variety of commercial and public resources and are not real-time in nature" (from their website), so it's just a matter of knowing why Indiana?

New Jersey is like the too, as Google gets its imagery from the State of New Jersey (Zoom in to NJ and you'll see "(C) State of NJ 2005").

Check out Cambridge, Massachusetts. You can pick out the make of cars, and see people walking around Harvard Yard. I think it has to do with which areas are providing the hi-res photos that GE can use.

I think some states just took initiative to have high definition satellite imagery of their state. Mass. is like this as well.

Missouri is like this too. I think it has to do with the state's funding for such things.

Not all of the images on Google Maps is from satellites. IIRC some imaging is from planes, like the highest resolution imaging in Las Vegas. I've been told LV uses these images to ensure people with pools pay the appropriate taxes.

I guess it depends on if there was a reason for high resolution imaging and if Google could get their hands on it.

Best answer: Indiana Spatial Data Portal. This is probably the source of the data. It's free (as in speech) and is aerial photography, not satellite. Other states have similar data available, but I believe Google has constraints on the age of the data. Which means they won't take Connecticut's 1991 data even though it's much better than the current Connecticut imagery.

(The page with the Massachusetts data has a good description of how they process the data, BTW.)

Response by poster: OK, whew...
Never noticed Missouri, Jersey, etc.
Guess Indiana has that odd grey color that stands out against all the green and thought it was unique, and therefore, skeery. Ya know?
Next step: real time and resolution down to a few feet! ala Enemy of the State, just don't look up!

Side question: What is/are your favorite place(s) to look at using Google Maps?

1) It's a reaction to the whole closed meeting / Bobby Knight firing scandal. The plaintiffs in the class action suit against the university administration have chipped in for 24 hour satellite surveilance of the highest resolution possible in order to track the movements of the trustees in support of their claim that they regularly hold secret, closed-door meetings. Google maps is just a secondary beneficiary.
-or-
2) It's the FBI tracking the doings of the strong ELF contingent in the state who routinely spike trees in the various national and state forests.
-or-
3) I am being most unhelpful and breaking guidelines for no good reason...

Damn good question though.

Related Question: Why are the google earth images so much better than maps.google.com? (eg: Geneva, Swtizerland). The mind boggles.

Best answer: The difference with the High Res images in Indiana, New Jersey, Massachusetts, and Missouri is that they aren't Satellite Imagery. They are high resolution aerial imagery that is collected by those states and either sold to or provided to Google by the states.

Answer for the Related question: The images used in GE are the same images that are used in Google Maps. The difference is that you can zoom in closer in GE the in Google Maps.

Best answer: Most likely it has something to do with INGISI, the Indiana GIS Initiative. Not only is there an ongoing orthophotography project, Indiana is a pilot state for the RAMONA mapping metadata project.

This might also have something to do with the agrarian nature of the state. A lot of farmers will purchase aerial photographs of their farmlands to aid them in planning what crops, fertilizers, etc. they will use in each field. It makes sense to me that Google would use this preexisting source of aerial photographs for their own maps.

I'm from Owosso! Swear ta gawd! Born and raised. Seriously, that's crazy!

I went to Indiana University for grad school. It's one of the most wired campuses in the country. It's also a research one school. May not relate to the reason, but I'm never surprised when Indiana is at the center of of tech things... just because of IU.

Actually, Indiana is about in the middle of the pack when it comes to being agrarian. The southern part of the state is too hilly, and the topsoil too sparse. The northern part of the state is dominated by rust-belt industries. Most cities in Indiana are either factory towns or mine (limestone, coal, gypsum) towns. Agriculture in Indiana uses 65% of the total land area, compared to 90% for Iowa and Kansas, and 75% for Illinois.

A friend of mine works at the Dept of Geography at Mizzou, where they wrote a high-tech shit-spreading (fertilizer) figuring program. This required really good data, both view and topo, and while they were at it, the data was added to the public record. I recall him talking about Indiana being the only other state with as good of data as Missouri.

Nerbaska is the same (hi-res) way. At least in that state's case, the reason is because any development (urban or rural) needs to conform to accepted practices for flood plain management.

When you live in flat-state land, you have to design in terms of a 100-year floodplain, otherwise you might find your brand new (expensive) highway conduit underwater in a few years. This is also one of the reasons you have so many members of the Army Corps of Engineers living in the mid-west.

It's so the missles can target Indiana more accurately

The Newport Chemical Depot, where VX gas is stored, is located in west central Indiana.
