Geolocating

Geolocating is the process of determining the latitude and longitude of crashes or other events of interest. UMTRI researchers have developed a method of geolocating truck crashes using police reports and other information collected as part of its continuing TIFA survey of medium and heavy truck crashes. The latitude and longitude is determined, along with an estimate of the precision of the location. Statistical quality control methods are used to ensure that the process stays within predetermined bounds. Adding the latitude and longitude to crashes and other events that occur within space allows information from other geospatial files to be added to the crash (or other) record and analyzed using the tools of Geographic Information Systems.
