MapScore runs a portal for scoring probability maps for lost-person behavior, using actual cases from the International Search & Rescue Incident Database (ISRID). See this post for more details. Or search sarbayes.org for posts, papers, and talks.
MapScore was funded by an NSF REU grant to George Mason & Brigham Young Universities, and used to be hosted at http://mapscore.sarbayes.org, run from a desktop server at the George Mason University C4I Center. It was eventually suspended due to not much use.
This GitHub site includes a subset of the ~400 ISRID cases that were used for MapScore. ISRID is available from Dr. Bob Koester at dbS-SAR. The Arizona, New York, and Yosemite cases included here are free for distribution.
An ArcGIS-based ISRID data collection form is also available online.
