Public Footpaths

View full metadata https://www.cambridgema.gov/GIS/gisdatadictionary/Basemap/BASEMAP_PublicFootpaths Description City of Cambridge, MA, GIS basemap development project encompasses the land area of City of Cambridge with a 200-foot fringe surrounding the area and Charles River shoreline towards Boston. The basemap data was developed at 1" = 40' mapping scale using digital photogrammetric techniques. Planimetric features; both man-made and natural features like vegetation, rivers have been depicted. These features are important to all GIS/mapping applications and publication. A set of data layers such as Buildings, Roads, Rivers, Utility structures, 1 ft interval contours are developed and represented in the geodatabase. The features are labeled and coded in order to represent specific feature class for thematic representation and topology between the features is maintained for an accurate representation at the 1:40 mapping scale for both publication and analysis. The basemap data has been developed using procedures designed to produce data to the National Standard for Spatial Data Accuracy (NSSDA) and is intended for use at 1" = 40 ' mapping scale. Where applicable, the vertical datum is NAVD1988. About Edit Dates This data is automatically updated on a set schedule. The Socrata edit date may not reflect the actual edit dates in the data.

Miovision Traffic Volume Data (All)

Traffic data comes from sensors installed at city intersections. These sensors do not take video of traffic, but instead determine by size whether each passing vehicle is a car, truck, bike, van, etc. The table below shows traffic at each intersection in 15-minute increments. This data set is grouped by directionality; each row is a sum of all the vehicles of a specific type that entered and exited the intersection in the same directions during the same 15-minute time window. To see this data grouped together further (by vehicle type, intersection, and time, disregarding directionality), see https://data.cambridgema.gov/Traffic-Parking-and-Transportation/resource/sqpt-e4ih) This dataset contains counts for different kinds of vehicles. For pedestrian counts, see https://data.cambridgema.gov/Transportation/MioVision-Daily-Pedestrian-Counts/7zcp-kyfg/about_data.

Medical Events

The Medical Events data set reflects information approved for general release by the Cambridge Police Department and the Cambridge Fire Department. All entries are inputted by dispatchers in the Emergency Communications Center (ECC). This data set does not reflect all events received by the ECC. Certain entries are not included due to concerns related to privacy, criminal investigation, or protected data. Additionally, not all entries reflect a dispatched response and some data may reflect a duplicate entry for a specific incident. The decision for a medical incident to be coded as one of the three types is not a reflection of the importance of the call, and should not be misconstrued to mean that the dispatcher or Cambridge ECD feels that the call or caller are unimportant. We strive to provide the best possible emergency service to our constituents, and never withhold care due to classification. Within each Chief Complaint, there are rankings of severity and priority; for privacy and security reasons, we do not provide this information, but this internal ranking is often as important to the dispatcher as the category. All calls received at the Cambridge ECC are treated with the utmost care and respect.
