Esri has actively participated in the spec activity from the very beginning. To this end, we were one of the very early adopters of the specification ( early support even before the spec was approved by OGC membership). Continue reading

LAS Optimizer Updated to Perform Faster Decompression

Esri’s LAS Optimizer has been updated to include support for parallel decompression. The initial version supported parallel processing when going from LAS to Optimized LAS, but the other direction, going back to LAS, was single threaded. It’s now parallel in both directions. This significantly decreases the time it takes to decompress the files and is worth the update.

Esri LAS Optimizer: LAS Optimizer
General Information: Esri Introduces Optimized LAS

Vehicle Trip Discovery with GIS Tools for Hadoop

An interesting task in highway management is to study potential impact of driver carpooling, based on an analysis of automatically collected automobile GPS position data. To identify potential enhancements to carpool participation, we set out to study places that have the highest numbers of trips with similar origin and destination locations. The source data for this experiment consists of nearly 40 million vehicle position records assembled from a single day of GPS-collected vehicle positions. The position data consists of longitude and latitude along with date, time, and speed. We used the Hadoop MapReduce framework for distributed parallel computation, considering its capability for analyzing larger data sets. Continue reading
