Explore how high-resolution satellite imagery reveals dramatic global events as they happen, from the devastating Sri Lankan tsunami and volcanic eruptions to the aftermath of bombings in Baghdad captured in digital maps.
I highlighted Google Sightseeing, a tool for exploring the United States through satellite imagery. This early look at Google Maps also points to Flickr communities like 'memory maps' for finding interesting geographical landmarks and crowdsourced visual data.
I'm checking out the new Google Maps API, though it strangely fails on Geocities. I've shared resources like Google Maps Mania and a London traffic map to highlight how developers are already using these early mapping tools.
I analyze the launch of Google Maps, noting its superior web interface and intuitive routing. While limited to the US at start, I expect a global expansion following Google's acquisition of Keyhole for its geospatial data.
I examine the original technical implementation of Google Maps, which utilized hidden IFrames for server communication rather than XMLHttp. The system also leveraged 8-bit alpha channel PNGs to render realistic shadows for map markers and popups.
I shared a detailed breakdown of the addressing system used by Google Maps in its early years, explaining how coordinates and URLs are structured to pinpoint specific geographic locations on the web.
