Metadata and the micro-ecology of data.
In an ICT lesson, my son was shown how to create HTML pages in a text editor, and then in MS Word. The teacher did admit that Word was more verbose. I said the same thing, and then felt obliged to prove it to him. I wrote two simple 'Hello world' pages: one in plain HTML, one using HTML generated by Word. The simple HTML has 50 characters, the Word version has 1392. (26 times as much, though the ratio would be different if the document was longer and more complex.) Serious implications for the ecology of data, a science that the world needs.
Google Streetmaps
A civilian version of the GKB, Google Streetmaps drives through cities photographing us and publishing the results.
The GKB: a database of everything.
The US National Geospatial Intelligence Agency recently has recently announced that the Worldview 1 spy satellite is operational. When WorldView 2 comes on stream, the two will supply 1 million square km per day of high-resolution earth imagery. The planned GEOINT Knowledge Base (GKB) may soon become the world's most massive database.
