http://www.gridsurvey.com is host to 2 cross-linked databases.
The first is a Second Life Region Database detailing for all Main Grid Regions :
*Grid Position
*Maturity Setting
*Linden owned vs Private Estate
*When the region first appeared
*When the region was removed from the grid if no longer current
*Texture UUID's for the Regions Terrain and Object Maps
*List of all Published Incidents in that region
*Historical list of all Map Texture UUID's
The Region Database contains all regions surveyed since March 2008 and is normally updated daily. It currently holds 48905 regions of which 29306 are currently live on the Grid. This is the public copy of the database I use for my weekly Grid Survey report I publish here http://www.sluniverse.com/php/vb/virtual-business/8523-new-second-life-sims-past-19.html
The Second database is a Second Life Published Incident Repository which holds the following details for all Published Incident Reports:
*Date of Incident
*Violation (AR Category)
*Region where the Incident was reported
*Description of the Incident
*Action taken by Linden Lab
This data goes back to June 2007 and is an accurate record of all known officially published Second Life incident reports (currently 21741) . It is not all reported ARs or even all resolved ARs but is all those which are reported on the Second Life Incident Blotter. This database is updated hourly .
There are plans to provide dynamic summary charts of both Databases in the near future.
