This dataset includes street centerlines in the City of Worcester, MA. The separate Street Name Table can be joined to this dataset to add the associated street names to the respective street centerlines.The fields "Official" and "Admin" enable users to select or draw centerlines for various purposes. For example, DPW&P maintains the Official Street Map and will use the "Official = yes" to model this. Major Roads are categorized as public streets on the official map (Official = 0 Admin = 0) or interstates, which are not on the official map and administered by other jurisdictions (Official = 1 Admin = 4).

HOLC, in consultation with local real estate professionals and local policymakers, categorized neighborhoods in hundreds of cities in the United States into four types: Best (A), Still Desirable (B), Definitely Declining (C), and Hazardous (D). So-called “hazardous” zones were colored red on these maps. These zones were then used to approve or deny credit-lending and mortgage-backing by banks and the Federal Housing Administration. The descriptions provided by HOLC in their reports rely heavily on race and ethnicity as critical elements in assigning these grades. According to the University of Richmond's Mapping Inequality project, “Arguably the HOLC agents in the other two hundred-plus cities graded through this program adopted a consistently white, elite standpoint or perspective. HOLC assumed and insisted that the residency of African-Americans and immigrants, as well as working-class whites, compromised the values of homes and the security of mortgages” (Mapping Inequality). HOLC’s classifications were one contributory factor in underinvestment in a neighborhood, and generally, although not always, closed off many, especially people of color, from the credit necessary to purchase their own homes.The 15 Worcester neighborhood zones included on the map are ordered from Zone 1 (categorized as "Best") to Zone 15, with the highest numbered zones included in the least desirable "Hazardous" category. The exact descriptions used by HOLC to classify the neighborhoods in 1936 are included, and therefore may contain some disturbing language. Many scholars and institutions have focused their efforts on tracking the effects the 1930s redlining maps still have today. The Mapping Inequality project by the University of Richmond has collected and analyzed a comprehensive set of redlining maps for more than 200 cities in the U.S. One of their conclusions is that, for most cities, there are striking and persistent geographic similarities between redlined zones and currently vulnerable areas even after eighty years. See the Mapping Inequality website for more information (https://dsl.richmond.edu/panorama/redlining).This digitized version prepared by the Worcester Regional Research Bureau was based on a scanned copy from the National Archives, obtained thanks to Dr. Robert Nelson, the Digital Scholarship Lab, and the rest of his team at Mapping Inequality at the University of Richmond. Dr. Nelson worked with The Research Bureau directly to track it down in the Archives.Informing Worcester is the City of Worcester's open data portal where interested parties can obtain public information at no cost.

The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line File is designed to stand alone as an independent data set, or they can be combined to cover the entire nation.Block Groups (BGs) are defined before tabulation block delineation and numbering, but are clusters of blocks within the same census tract that have the same first digit of their 4-digit census block number from the same decennial census. For example, Census 2000 tabulation blocks 3001, 3002, 3003,.., 3999 within Census 2000 tract 1210.02 are also within BG 3 within that census tract. Census 2000 BGs generally contained between 600 and 3,000 people, with an optimum size of 1,500 people. Most BGs were delineated by local participants in the Census Bureau's Participant Statistical Areas Program (PSAP). The Census Bureau delineated BGs only where the PSAP participant declined to delineate BGs or where the Census Bureau could not identify any local PSAP participant.A BG usually covers a contiguous area. Each census tract contains at least one BG, and BGs are uniquely numbered within census tract. Within the standard census geographic hierarchy, BGs never cross county or census tract boundaries, but may cross the boundaries of other geographic entities like county subdivisions, places, urban areas, voting districts, congressional districts, and American Indian / Alaska Native / Native Hawaiian areas. BGs have a valid code range of 0 through 9. BGs coded 0 were intended to only include water area, no land area, and they are generally in territorial seas, coastal water, and Great Lakes water areas. For Census 2000, rather than extending a census tract boundary into the Great Lakes or out to the U.S. nautical three-mile limit, the Census Bureau delineated some census tract boundaries along the shoreline or just offshore. The Census Bureau assigned a default census tract number of 0 and BG of 0 to these offshore, water-only areas not included in regularly numbered census tract areas.Informing Worcester is the City of Worcester's open data portal where interested parties can obtain public information at no cost.

This map service contains both polygon and linear features for the boundaries of the Massachusetts State House of Representatives districts, which were signed into law on November 4, 2021, with Chapter 83 of the Acts of 2021. These boundaries began to be used with the fall 2022 elections and are based on demographic data from the 2020 U.S. Census.Member names from the results of the November 2022 election were populated in January 2023 and updated in February 2024. An update to the attributes due to a special election in the 6th Worcester District was added in June 2024.Member names from the results of the November 2024 election were populated in January 2025.See full metadataFeature service also available.

Urban heat islands are small areas where temperatures are unnaturally high - usually due to dense buildings, expansive hard surfaces, or a lack of tree cover or greenspace. People living in these communities are exposed to more dangerous conditions, especially as daytime high and nighttime low temperatures increase over time. NOAA Climate Program Office and CAPA Strategies have partnered with cities around the United States to map urban heat islands. Using Sentinel-2 satellite thermal data along with on-the-ground sensors, air temperature and heat indexes are calculated for morning, afternoon, and evening time periods. The NOAA Visualization Lab, part of the NOAA Satellite and Information Service, has made the original heat mapping data available as dynamic image services.Dataset SummaryPhenomenon Mapped: heat indexUnits: degrees Fahrenheit Cell Size: 30 metersPixel Type: 32 bit floating pointData Coordinate Systems: WGS84 Mosaic Projection: WGS84 Extent: cities within the United StatesSource: NOAA and CAPA StrategiesPublication Date: September 20, 2021What can you do with this layer?This imagery layer supports communities' UHI spatial analysis and mapping capabilities.
