Tasmanian Crash database is the authoritative reference used by Tasmania Police to store vehicular crashes in Tasmania as reported by Tasmania Police, or in the case of property damage only crashes, reported by the public. The Crash Data database is used to store, manage, and query all reported Tasmanian vehicle crashes. The Crash Data is accessed via the Crash Data Manager (CDM) a web based query and reporting tool that is used by State Growth, Motor Accident Insurance Board, Tasmania Police, and local government authorities.

Vehicle crash data (classified as fatal, serious, minor, first aid, property damage, etc) attended by Tasmania Police or provided by the general public via the Tasmania Police crash reporting tool (https://www.reportacrash.police.tas.gov.au/TCR/crashReport/welcome) are held in the database. The crash data is uploaded to the (Department of State Growth) Crash Data database (CDM) via a web service (JSON string) from Tasmania Police. State Growth undertakes subsequent validation checks of data once uploaded. Validation checks are made of the attribute values and spatial location. This database has stored crashes dating back to 1998 and has undergone a number of changes to process since original inception. Both tabular and coordinate information is stored in the database. A wide array of fields relating to the accident are stored (~200 fields).

Positional accuracy: The location of crashes has been collected in different ways over time. Prior to 4/2012 the location of a crash was recorded as a free text description, with reference to nearest power pole number for instance. This description was interpreted and entered as a coordinate pair into the State Growth database. Post 4/2012 Tas Police use Latitude and Longitude coordinates digitised via a web mapping interface (Google maps based). Accuracy is estimated at +/-20m 90% of the time. Attribute accuracy: Attributes entered by DPEM are validated by staff at the State Growth. Any anomalies are flagged for checking before committing to the CDM database. Attributes are estimated to be 100% correct. Completeness: This database contains all accident and certain property damage vehicular crashes reported to Tas Police in Tasmania from 1998 onwards.
