Computer generated buiilding footprints for Maryland. The methodology for the generation of the building footprints can be found at: https://github.com/Microsoft/USBuildingFootprints. These building footprints should be used a reference only and the geometries are not considered accurate enough to provide detailed estimates related to their location, area, or associated attributes.This is a MD iMAP hosted service layer.

This data set consists of digital data describing sites under the oversight of Maryland Department of the Environment's (MDE) Land Restoration Program (LRP). Within the LRP, two divisions exist to oversee assessment and remediation of potentially contaminated sites. The State Assessment and Remediation Division includes the Voluntary Cleanup Program (VCP) and CHS Enforcement Sections. The Federal Assessment and Remediation Division includes the Federal IRP Support Section and NPL/Site Assessment section. This dataset describes any VCP applicant or responsible party for the LRP oversight for each site relative to these programs. This layer is intended for use in concert with the LRP Sites layer.This is a MD iMAP hosted service.

These data sets consist of digital data describing sites under the oversight of Maryland's Land Restoration Program (LRP). Within the LRP, three programs exist to investigate eligible properties with known or perceived controlled hazardous substance contamination, protect public health and the environment, accelerate cleanup of properties, and provide liability releases and finality to site cleanup: the Voluntary Cleanup Program (VCP), the Brownfields Initiative, and State Remediation Sites. This dataset describes and details each site relative to these programs.This is a MD iMAP hosted service.

This is a comprehensive point theme that incorporates Computer Assisted Mass Appraisal (CAMA) property land characteristics for land types associated with a given parcel account number (ACCTID field). Data for the CAMA Land point theme are obtained from the State Department of Assessments and Taxation for all jurisdictions on a yearly basis. This is a multi-record per parcel account number point theme. The CAMA Land point theme can be joined to the CAMA Core point theme on parcel account number. The CAMA Land point theme should not be joined to the CAMA Building or Building Subareas point themes because this theme is a property and not a building point theme. For more information on the attribute definitions please see the MdProperty View User's Guide, available for download at https://planning.maryland.gov/Pages/OurProducts/DownloadFiles.aspx.

The service depicts the number of broadband service providers per census block and the layer represents the National Telecommunications Information Administration (NTIA) State Broadband Data Development Program (SBDD) area of broadband availability. The number of broadband providers per census block is illustrated. Area of broadband availability refers to those individual US Census Blocks, less than 2 square miles, where each facilities-based provider of broadband service can provide broadband services of minimal characteristics within 7 - 10 business days. For this purpose, ''broadband service'' is the provision, on either a commercial or non-commercial basis, of data transmission technology that provides two-way data transmission to and from the Internet with advertised speeds of at least 768 kilobits per second (kbps) downstream and greater than 200 kbps upstream to end users, or providing sufficient capacity in a middle mile project to support the provision of broadband service to end-users within the project area. For this purpose, an ''end user'' of broadband service is a residential or business party, institution or State or local government entity that may use broadband service for its own purposes and that does not resell such service to other entities or incorporate such service into retail Internet-access services. Internet Service Providers (ISPs) are not ''end users'' for this purpose. An entity is a ''facilities based'' provider of broadband service connections to end user locations if any of the following conditions are met: (1) It owns the portion of the physical facility that terminates at the end user location; (2) it obtains unbundled network elements (UNEs), special access lines, or other leased facilities that terminate at the end user location and provisions/equips them as broadband; or (3) it provisions/equips a broadband wireless channel to the end user location over licensed or unlicensed spectrum. For this purpose, ''broadband service'' is ''available'' at an address if the provider does, or could, within a typical service interval (7 to 10 business days) without an extraordinary commitment of resources, provision two-way data transmission to and from the Internet with advertised speeds of at least 768 kilobits per second (kbps) downstream and greater than 200 kbps upstream to end-users at that address.

This layer is extracted from The High Resolution National Hydrography Dataset Plus (NHDPlus HR). This is an integrated set of geospatial data layers, including the best available National Hydrography Dataset (NHD), the 10-meter 3D Elevation Program Digital Elevation Model (3DEP DEM), and the National Watershed Boundary Dataset (WBD). The NHDPlus HR combines the NHD, 3DEP DEMs, and WBD to create a stream network with linear referencing, feature naming, "value added attributes" (VAAs), elevation-derived catchments, and other features for hydrologic data analysis.This is a MD iMAP hosted service layer.

Roadway Access Control data consists of linear geometric features which showcase the types of control over vehicle access to public roadways in the State of Maryland. Roadway Access Control data is commonly classified by three (3) control types, which are Full Access Control, Partial Access Control, and No Access Control. Roadway Access Control data is primarily used for general planning purposes, investment requirements modeling to calculate capacity and estimate type of design, in truck size and weight studies, and for Federal Highway Administration (FHWA) Highway Performance Monitoring System (HPMS) annual submission & coordination. The Maryland Department of Transportation State Highway Administration (MDOT SHA) currently reports this data only on the inventory direction (generally North or East) side of the roadway. Roadway Access Control data is not a complete representation of all roadway geometry.Roadway Access Control data is developed as part of the Highway Performance Monitoring System (HPMS) which maintains and reports transportation related information to the Federal Highway Administration (FHWA) on an annual basis. HPMS is maintained by the Maryland Department of Transportation State Highway Administration (MDOT SHA), under the Office of Planning and Preliminary Engineering (OPPE) Data Services Division (DSD). Roadway Access Control data is used by various business units throughout MDOT, as well as many other Federal, State and local government agencies. Roadway Access Control data is key to understanding the types of control over vehicle access to public roadways in the State of Maryland.Roadway Access Control data is updated and published on an annual basis for the prior year.

This layer is a network of public ditches that cover large areas of the middle parts of the Delmarva. These ditches help drain 183,000 acres of land composed of crop land, forest land, roadways, commercial areas and home sites, conveying storm water runoff from rural towns on Maryland’s Eastern Shore. The Maryland Department of Agriculture worked in conjunction with the Eastern Shore Regional GIS Cooperative (ESRGC) at Salisbury University to produce this comprehensive digital representation of Public Drainage Associations and Public Watershed Associations on Maryland’s Eastern Shore.This is a MD iMAP hosted service layer.
