Community Crime Mapping

Welcome to the City of Mercer Island Police Department's Neighborhood Community Crime Mapping Website

The Mercer Island Police Department is pleased to announce an interactive neighborhood crime mapping program.  Crime Mapping is a web-based program that was developed for the Police Department to provide the community with information about recent crime activity in their neighborhood.  This service is provided internally through our GIS division and Mercer Island specific crime data is extracted from the Police Department’s records system, allowing citizens to view up to the last 6 months of crime data by various search parameters, to include a date range, crime type, or around a specific address.   The data will be illustrated on a map and the various crimes will be depicted by various crime type icons, each containing general details of the incident.  Community members will also be able to develop queries that can be shared and printed.

Notes on use:

When the map first loads, it will load all data from the past 6 months. 

SUMMARY INFO section 

The SUMMARY INFO does a  COUNT of all the crime

You can expand each crime type in the Info Summary section and, select a crime and a pop-up will appear on the map with more information If you zoom into the map (using the +/- or by holding down the SHIFT key and drawing an area), the Info Summary section will re-do the counts for that area only

FILTER section on the bottom left of the map:

To narrow down the search, you can FILTER by date range in the bottom left or FILTER by Crime Type (or both).
