Upon loading HolyokeGIS, the user will see several menus. The top three blue buttons represent switches to display population and density data for either neighborhoods or wards and precincts.
Neighborhoods as well as Wards and Precincts may be displayed by selecting either of the three options listed by the magenta radio buttons. Click on any of these polygons to display the respective neighborhood name or ward/precinct number, as well as the population or density for that area. A zoning map is also available, but displays separately from other data to avoid making the map too busy.
To access crime data click the title or arrow of the its console to open the filter menu. Clicking or tapping the large yellow switch to the left will display crime for all categories for the previous year. Please note that your browser may slow considerably when all data is displayed at once.
In the dropdown menu you will see all categories of offenses listed with colors corresponding to each category. To show or hide a specific category, click the large round button to the left of the corresponding label. Once data is plotted on the map you may click on any point to see its category, address, and what month/year it occurred.
A number of buttons appear above this list which function as follows-
Displays police station and substation locations.
Display mode button, incidents displayed as overlapping points.
Display mode button, incidents displayed as clusters. To view individual incidents click on the cluster number to zoom in until separate points appear. When this mode is active the date filter cannot be changed.
