Zoom in closer to where the Russian River bends around Fitch Mountain on a new online crime map and bubbles dot the shore: Simple assault, burglary, parole violation, larceny.
Underneath the sleek digital map is a trove of data that in the past was only available via a phone call or by requesting law enforcement records.
The Sonoma County Sheriff's Office this month joined the Santa Rosa Police Department in uploading daily crime reports onto the map, called RAIDS Online.
Employing geographic information system technology, or GIS, data such as the time and type of a crime is linked to the place where it occurred, creating a color-coded visual archive of crime in the county.
The interactive map was on display last week at the Finley Center in Santa Rosa, part of an event showcasing the incredible volume of geospatial data held by county agencies.
"Del Rio Woods, that's where we go rafting," said Geri Biehl of Healdsburg, squinting at incidents plotted on the river bend.
"Fight at the beach, I'm guessing," said Sheriff's Office crime analyst Matthew Harris. "It opens your eyes."
The public can find the map on the Police Department and Sheriff's Office websites or through an iPhone application.
The Police Department started uploading crime data to RAIDS nearly two years ago, and the records go back to 2009. The Sheriff's Office records go back to 2008, as well as some older reports from unsolved crimes.
Some kinks in system
Markers on the map represent incidents that led an officer to write a crime report. But that does not necessarily mean a person was arrested.
For example, the map shows 49 crime reports on Election Day, from a robbery in Santa Rosa's Railroad Square to an embezzlement south of Cloverdale. Most crimes occurred between 2 and 6 p.m.
But it's not a real-time map. Records may not show up for several days if they haven't gone through three levels, including the officer who writes it, a sergeant and the records department.
"What we don't show in RAIDS are any reports that haven't reached the final approval process," said Conan Mullen, a crime analyst with the Police Department.
And there are other kinks to iron out.
The Feb. 5 shooting that killed a Santa Rosa masseuse is categorized as an aggravated assault and not a homicide. That's likely because the victim succumbed to her injuries hours after police began investigating the crime, Mullen said.
"There's a quality-control process, and before the end of the year, it will get corrected," Mullen said.
Also, the markers do not appear exactly where the crime occurred.
Sheriff's Office reports point to the nearest intersection. In Santa Rosa city limits, crime events show up close to the block where something happened, such as near the 900 block of Clark Street.
Some cases appear to have occurred at the Police Department or Sheriff's Office because that is where a report was taken.
The agencies did not pay for the service, aside from the initial manpower required to sync the automated systems.
200 agencies in 39 states
"Our ultimate goal is to have the first national map of crime -- that doesn't exist," said Sean Bair, a former police officer and crime analyst who created RAIDS Online.
