Yet another riff on Google Maps on Flickr: the Feel Small Project, wherein participants take screenshots of their location on Google Maps satellite imagery at every zoom level, then build a slideshow that zooms from the tightest to the widest…
More Sites About Google Maps
Since its launch a little less than three months ago, Google Maps has generated more buzz than any other mapping site since I’ve been paying attention to them. Adding satellite photos only made it worse. That buzz can be measured…

Reaping the World Wind
As I said in my brief entry about NASA World Wind last November, my lack of access to a Windows PC — at least one I can install big software packages on — prevented me from checking it out. Manuel…
A Google Maps Update
I’ve been saving up a bunch of Google Maps satellite imagery links for you over the weekend. Google Maps and Accountability: Dave Shea explores the possibilities of using Google Maps as a tool for whistleblowing rather than a threat to…
More on Google’s Satellite Images
Flickr users have gone nuts with posting screenshots of Google Maps’s new satellite photo feature (see previous entry), if the “map” and “maps” tags are any indication. There’s also a new Flickr group called Memory Maps, the idea of which…
Google Maps Adds Satellite Images
Google Maps has added satellite images to its service as of late Monday, and it’s done so in a really useful manner: one click toggles between maps and satellite photography. Try zooming in without your jaw hitting the floor. The…
Dubai Aerial Photography
Aerial photography of Dubai, which is apparently in the midst of a beggar-the-imagination construction boom. Via Things Magazine; see MetaFilter (1, 2) for background….
Satellite Images and the Weather
A couple of links tonight; the tenuous connection is that they both have to do with the weather and satellite imagery. I’ve never heard of Software MacKiev before, but they appear to do educational software for the Mac. They’ve released…
Question: Long Island Aerial Map?
(Questions are coming in fast and furious here at The Map Room; I’m afraid I’ll have to be selective. This little experiment is working far better than I had expected.) Rocco Cammarota writes, “Can I get a map (aerial view)…
Tsunami Wave Height Images and Animation
More on the Indian Ocean tsunami. The NOAA has a page of images that show the height of the tsunami wave as it progressed (and expanded) over time, using data collected from radar satellites. There’s also an animation of the…
Before and After the Tsunami: Satellite Photos
A collection of satellite photos showing areas of Sri Lanka and Indonesia before and after they were devastated by the tsunami. The photos from the Banda Aceh region are particularly horrifying. Via Rebecca’s Pocket. Tsunami Relief….
Keyhole and World Wind
Joel takes a look at a couple of software packages that do neat things with satellite imagery: Keyhole, which was taken over by Google a while back; and NASA World Wind. They’re Windows-only, so I can’t try them out —…
World Sunlight Map
The World Sunlight Map is a neat trick: it shows which parts of the Earth are currently in daylight and which are in darkness. It’s a simulation that begins with composite images of the Earth by day (sans clouds) and…
More Satellite Imagery
A couple of satellite-imagery links from Plep; I don’t think I’ve seen these before. Satellite Images of Earth at Night, from the International Dark-Sky Association. Usually you see night maps of the entire planet (e.g. see previous entry: APOD: The…
Flipping Between Satellite Images and Maps
MultiMap uses JavaScript to toggle between maps and satellite images of a given locale. One of a part of London has been making the rounds of the blogosphere this week (see Boing Boing and MetaFilter)….
SatBlog
SatBlog is a blog about satellite imagery; since its restart last August it’s been focusing mainly on the Middle East (especially Iraq) and on all those bloody hurricanes. A lot of news stories can be illuminated by satellite photography —…
La terre vue du ciel
La terre vue du ciel is a collection of aerial photography. The photos are uncaptioned and unattributed: you pretty much have to guess what they are, where they’re from and from what altitude they were taken. Via Making Light….
APOD: The Earth at Night
Yesterday’s Astronomy Picture of the Day was a composite photograph of the Earth at night, replete with all the lights you’d expect. High-resolution versions also available. Via Slashdot….
London Tube Map Satellite Image
For you Tube map freaks: R. Gardiner has taken a geographically accurate map of the London Underground and superimposed it on a satellite image of the city. Very effective. Via Here Be Dragons….
Window Seat
If you’re into maps, then you’re also probably the sort of person who, when flying, asks for a window seat and does nothing but stare out the window for the duration of the trip. Though I frequently ask for an…
Ryongchong Explosion
Satellite images of Ryongchong, North Korea, before and after the explosion (via MetaFilter)….
Ikonos Satellite Image Galleries
Space Imaging presents what they call the top ten Ikonos satellite images for 2003 (via MetaFilter). And there’s some more neat stuff in their gallery (also via MetaFilter)….

SpaceDaily reports that NASA has released data covering Eurasia from the Shuttle Radar Topography Mission (SRTM). [T]he new digital elevation data set showcases some of Earth’s most diverse, mysterious and extreme topography. Much of it previously had been very poorly…
Bam After the Earthquake
This is a little dated now for breaking news; I was saving it during the downtime. But still relevant: one-metre-resolution satellite images of Bam, Iran, after the earthquake. Via Here Be Dragons….
