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.
