Beyond the Routing Algorithm

A brief look at the benefits and dilemmas of location-based tracking.

Just an urban routine, nothing out of ordinary -- or so it seemed. In reality, the driver was committing a series of thefts.

"If the stop is approved, or authorized, it'll come up green. But if it's not an approved stop, it shows up in yellow," triggering an alert, he said.

Spatial Tech -- 3D Photorealistic Modeling Using Geobrowsers

By James L. Sipes

When geobrowsers such as Google Earth, Microsoft Virtual Earth and NASA's WorldWind were introduced, they provided a new, exciting way to view our world. They gave us a quick, efficient and easy-to-use interface for linking satellite imagery, maps, terrain, 3D buildings and other geospatial information. Many professionals who work with geospatial data realized that these geobrowsers could be effective visualization tools for sharing information because anyone with an Internet connection could use them.

Webcast: Introduction to ArcGIS Image Server 9.2
May 24, 2007
9:00 and 11:00 a.m. PDT
Georeferenced imagery is an invaluable component of GIS applications, but it can be difficult to work with because it involves huge files and requires tremendous amounts of processing to get it into a usable form. This free online seminar by ESRI shows how ArcGIS Image Server 9.2 revolutionizes the way georeferenced imagery in a geographic information system is used on the Web or across local area networks.
