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.

Abstract

The intended goal of this web app is to present publicly available geospatial information from the City of Holyoke in a novel way. This includes but is not limited to, arrest data, school and museum locations, health facilities, population statistics, municipal zoning and historic maps of the city. This web app was initially created when the developer found many preconceived notions about Holyoke's crime statistics went against the collected data and wished to compile this for their own policy research. Out of the interest of public safety all names and offenders addresses have been removed, however this information may or may not be available upon request from the Holyoke Police Department. This map is in no way meant to endorse or criticize the actions of the police or those charged, and due to the fact that calls may or may not result in criminal charges, those which did not end in an arrest have not been listed here. The author of this web app does not represent the municipal government, in accordance with Holyoke PD's disclaimer, does not seek to use this tool commercially, and will not in any way be generating revenue from ads or services related to its content.

This web page represents the work of a third party developer, including an interactive crime map showing locations of crimes and corresponds with police blotter arrest data listing dates, places, and types of crimes during various periods of time. This information is strictly for noncommercial, educational use and is not condoned by the Holyoke Police Department or any other agency of the City of Holyoke. The data used here may or may not have been screened further by the Holyoke Police Department’s quality control process and therefore may reflect:

• Information not yet verified by further investigation
• Information that may include mechanical or human error
• Preliminary crime classifications that may be changed at a later date based upon further investigation

Neither Isotypes, the City of Holyoke nor the Holyoke Police Department guarantee (either express or implied) the accuracy, completeness, timeliness, or correct sequencing of the crime data shown here. Isotypes, the City of Holyoke and the Holyoke Police Department shall have no liability for any error or omission, or for the use of, or the results obtained from the use of this information. In addition, Isotypes cautions against using the crime data to make decisions/comparisons regarding the safety of or the amount of crime occurring in a particular area. When reviewing crime information, the site user should consider that:

• The information represents only police services where an arrest was made and does not include other calls for police service.
• The information does not reflect or certify "safe" or "unsafe" areas.
• Areas with a high volume of foot traffic, vehicle traffic, and are densely populated may have more reported crimes than other areas. This does not necessarily mean more crime occurs there, but that more crime is reported there.
• Results displayed are not distinguished as attempted or completed crimes, and do not include results of subsequent legal action.
• Users should not rely on nor make decisions or comparisons based solely on the data offered on this web site; but should conduct additional independent verification and due diligence.
• The information will sometimes reflect where the crime was reported rather than where the crime occurred.

  This is a private site making no warrantee of safety, the use of the crime data in this atlas indicates the site user's unconditional acceptance of all risks associated with its application.
