Blue Marble

Blue Marble was a project for mapping the visible color of the Earth with about 1-km resolution. The beautiful resulting images have become very popular in the media and among the public.

Blue Marble is the name given to a single photo taken during an Apollo space mission, it is not a project.

Resolution

Rural areas are mapped at 100-150m resolution? The Landsat program images most of the world to 15m also see here and search for Landsat. Should this be updated? How about some discussion or at least links to spy satellite imagery, which is classified but guessed to be at 4cm resolution? cluth 09:21, 28 February 2006 (UTC)[reply]

There seems to be an awful lot of guessing about the image resolutions possible from military satellites. Another guess: it has never been better than 30cm GSD. It would also seem that the military is not developing drone/UAV-based reconnaissance technology for no good reason. Commercial small-UAV operators are routinely achieving 4cm resolution for specific projects, and large-format digital aerial imagery can achieve 2.5cm GSD. The issue of resolution is clearly no longer with the satellites. Aerometrex (talk) 03:45, 13 January 2014 (UTC)[reply]

Moving Images?

What's the point of this section? It seems to be somewhat random, singular, and under a heading to which I don't understand the relationship....--Koeppen 08:46, 26 June 2006 (UTC)[reply]

-REPLY MESSAGE- If you would like to download a broad spectrum of satellite data and images you can direct your request to: gosat@live.com this data is 100% free for private use.

Google's Intention

Perhaps someone should mention that in many countries, especially the U.S., google doesn't provide any more significant photo data to the public then is already available for sale by the government itself.

If somehow intensity is increased on an Earth surface (eg. an important monument) either by using halogen lamps or floodlights then if satellite takes image the image it would get will be a white image?? Please somebody answer.

Merger

I must say, I feel like Satellite Image Comparison should be deleted outright. It has no sources and just two large images that make up the article. Or are you thinking that a section of satellite imagery should say something about image comparison? I'd be ok with that too.--Will.i.am 00:55, 28 October 2006 (UTC)[reply]

Feeling is an unjustifiable for reason of deletion. The article in question is there for support of another article. This article Satellite Image Comparison is justified by its content as it supports a stream of facts coming from the articles water vapor, humidity, etc. DO NOT DELETE OR MERGE. --Hard Raspy Sci 17:47, 20 November 2006 (UTC)[reply]

It has since been deleted. -- Beland (talk) 01:48, 24 July 2015 (UTC)[reply]

NRO

The mention of the NRO's capability is most likely exaggerated and not cited in any way. There are theoretical limits to the resolution that can be obtained from that far out. —Preceding unsigned comment added by 63.255.213.130 (talk) 20:01, 27 February 2010 (UTC)[reply]

Cost per image?

Yes, price depents on resolution but what to expect if one would like to buy images? — Preceding unsigned comment added by 81.197.154.209 (talk) 12:16, 26 July 2013 (UTC)[reply]

The claim that aerial imagery is more expensive than satellite imagery should be vigorously contested. In the sub-metre resolution range, digital aerial imagery is much less expensive for new data collections on a per km2 basis. It also offers multispectral imaging capability, full 3D stereo capability and much higher resolution than even the best commercially available satellite imagery. Orthophoto production and digital terrain modeling is often an included service with digital aerial imagery service providers. The only way satellite imagery can compete with digital aerial imagery on cost is by reselling imagery from data archives. Aerometrex (talk) 03:24, 13 January 2014 (UTC)[reply]

Applications

Interesting article, either for inspiring content here or linking to: [1] -- Beland (talk) 01:49, 24 July 2015 (UTC)[reply]

Category:Satellite imagery

I just created Category:Satellite imagery. Please help out.

For instance there are many entries in Category:Earth observation satellites & Category:Space observatories that should have the category added to them.

External links modified

Hello fellow Wikipedians,

I have just modified one external link on Satellite imagery. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

References

I am going to add a few academic sources to the article. The last references were pulled over 3 years ago. One of the links no longer works. I'm going to re-pull some of the sites and articles as well.Timothy McC. (talk) 15:39, 13 February 2019 (UTC)[reply]
