In 2009, Data Driven Detroit partnered with Living Cities, the Detroit Office of Foreclosure Prevention and Response and Community Legal Resources (Michigan Community Resources) to conduct a survey of 1-4 unit residential structures and vacant lots in the City of Detroit. Surveyors went out in the field in August and September of 2009, and following this, data were entered into a database and cleaned. The survey collected information on property type, condition, vacancy, danger to the surrounding community, fire damage, and improvements on vacant lots.For more information on the DRPS, including aggregations and maps of the original data, please visit www.detroitparcelsurvey.org.Upon request, field description metadata is also available for this dataset.

This data is intended as a reference material of street and alley openings, but not designed for survey, accurate positioning, or legal documents. It is created as polygon feature class, dedicated information based on field measurements, types of Right of Way, and citations of Journal of the Common Council (J.C.C.) and legal description are included. The paper maps of the Street and Alley Openings, the raster layer version of those maps (Linen Map Markup Mosaic), and the Detroit parcel layer are used as base maps to create this data.The spatial reference is: WGS 1984 Web Mercator Auxiliary SphereThe street and alley openings were recorded from 1831 to 2022 throughout the whole city, and it will be updated weekly. The existed and/or active street and alley openings are ready to view, the authors are working on missing and historical records.Note: Special values within the 'Jurisdiction' field:"2" means that the feature was approved under Wayne County or the State of Michigan jurisdiction, No City record on file. "1" means that the feature was approved under City of Detroit jurisdiction."0" means the feature was approved per circuit court decision. No City record on file.

The Detroit Future City Strategic Framework is a land use planning document that was released in 2012. It outlines recommendations for transforming Detroit's land use policies and codes over the next fifty years, and covers a broad range of issues from economic and workforce development to transportation and green infrastructure. The shapes in this file represent the 50-year recommended land use for the City of Detroit, based on this plan. The geographies are based off of dissolved parcels from the City of Detroit Planning and Development Department. Field description metadata is available for download.

The Act51 Map Layer represents the road network that the City of Detroit reports to the Michigan Department of Transportation on a annual basis. The Act51 Map Layer identifies road jurisdictions for permitting and planning. Roads listed under the "MDOT" and "County" refer to the Michigan Department of Transportation and the Wayne County Public Services.

Detroit Street View (DSV) is an urban remote sensing program run by the Enterprise Geographic Information Systems (EGIS) Team within the Department of Innovation and Technology at the City of Detroit. The mission of Detroit Street View is ‘To continuously observe and document Detroit’s changing physical environment through remote sensing, resulting in freely available foundational data that empowers effective city operations, informed decision making, awareness, and innovation.’ LiDAR (as well as panoramic imagery) is collected using a vehicle-mounted mobile mapping system.

Due to variations in processing, index lines are not currently available for all existing LiDAR datasets, including all data collected before September 2020. Index lines represent the approximate path of the vehicle within the time extent of the given LiDAR file. The actual geographic extent of the LiDAR point cloud varies dependent on line-of-sight.

Compressed (LAZ format) point cloud files may be requested by emailing gis@detroitmi.gov with a description of the desired geographic area, any specific dates/file names, and an explanation of interest and/or intended use. Requests will be filled at the discretion and availability of the Enterprise GIS Team. Deliverable file size limitations may apply and requestors may be asked to provide their own online location or physical media for transfer.

LiDAR was collected using an uncalibrated Trimble MX2 mobile mapping system. The data is not quality controlled, and no accuracy assessment is provided or implied. Results are known to vary significantly. Users should exercise caution and conduct their own comprehensive suitability assessments before requesting and applying this data.

The NEZ-NR Districts dataset contains the Neighborhood Enterprise Zones district boundaries applicable to New and Rehabilitated facility projects. NEZ-NR districts are the original NEZ districts. NEZ is a tax abatement program intended to stimulate investment in designated areas of the city. NEZ-NR differs from NEZ-Homestead in that NEZ-NR covers new facilities and/or rehabilitated facility projects. In contrast, the NEZ-H program covers pre-existing residential property inhabited by owner-occupants only. NEZ-NR and NEZ-Homestead programs are administered jointly by the City of Detroit and the State of Michigan under Michigan's Neighborhood Enterprise Zone (NEZ) Act, PA 147 of 1992 as amended.

A record of district and dataset modifications from 1992-2017 is noted in the NEZ-NR District Boundary Update document available from the NEZ NR Changelog.

This map shows demographic and income data in Detroit. Assuming an assignment where the poverty fighting charity I work for would like to alleviate suffering among impoverished children in Detroit. Detroit is a Michigan city that always ranks among America's poorest urban centers. Orange circles have below average median household income, the darker shades indicate households with a very low income-close to poverty level. The size of the circles: larger circles indicate a greater number of children in the area.What stands out is the obvioud pattern of low-income households in the city center combined with areas of high child population. This pattern helps answer where in Detroit our charity will focus its resources to help children living in poverty-in places shown on the map where there is a cluster of several large dark Orange circles like Dearborn and Pontiac (for example). The charity may and will offer free after school care and/Or but not limited to breakfast programs.

The Detroit Land Bank Authority's (DLBA) Own It Now (OIN) program offers vacant homes for sale with a minimum offer price of $1,000. Homes are available on the DLBA website for sale 24 hours a day, 7 days a week and may be offered on at any time. Homes are sold as is and buyers are required to rehab the houses and ensure that they are occupied. The dataset provides information on the properties that have been successfully sold by the DLBA through the OIN program.

The Detroit Land Bank Authority (DLBA) works directly with individual buyers, as well as Community Partner organizations and developers to achieve their mission to return the city's blighted and vacant properties to productive use. They utilize a variety of sales programs to make homeownership and land purchases accessible to Detroiters. One of these programs is Own it Now (OIN).

Each row in the dataset represents an OIN home and includes data about the sale status, closing date for sold homes, sale price, and location information such as: address; parcel ID; and neighborhood.
