This dataset was initally scraped from Open Street Map using the following query:area sport=tennis;/*added by auto repair*/(._;>;);/*end of auto repair*/out;The users and contributors of OSM have all the credit for initially creating the dataset. This dataset will continually be updated with information as it becomes available. OIT-GIS in no way guarantees the accuracy or completeness of this dataset.

Esri ArcGIS Online (AGOL) Hosted Feature Layer for accessing the MDOT SHA Park and Rides data product.MDOT SHA Park and Rides data consists of point & polygon geometric features which represent the geographic locations & areas of MDOT SHA Park and Ride Facilities along roadways throughout the State of Maryland. This data product includes components related to counts of select space types and the usage of those types, averaged over the previous two inspection cycles (fall and spring of every year).MDOT SHA Park and Rides data is dynamically compiled & maintained by the MDOT SHA OIT Enterprise Information Services - GIS Team according to these data product requirements. OIT GIS staff members intimately familiar with this data maintenance process are Mr. John Shiu and Mr. Elliott Plack. MDOT SHA Park and Rides data is owned by the MDOT SHA Office of Planning & Preliminary Engineering (OPPE), under the MDOT SHA OPPE Regional Intermodal Planning Division (RIPD).MDOT SHA Park and Rides data symbology is defined by the regular vehicle occupancy percentile over the last two inspection cycles. The symbols are derived from the MUTCD D4-2 Park & Ride sign specification, and are colorized by the percentile. The colors are selected from the MUTCD color set:Green: 50% full or lessYellow: 50% to 75% full75% full or greaterFor additional information, contact MDOT SHA OIT Enterprise Information Services:Email: GIS@mdot.maryland.gov

The Transforming Neighborhoods Initiative (TNI) focuses and aligns government efforts in six geographic areas throughout the county with the goal to improve the quality of life. The map below represents the areas that are part of this initiative. This map is refreshed when needed.

Polygon features representing approximate location of tax parcels contained in County Assessor tax rolls in 2017 by the Governor's Office of Information Technology.

The information in the abstract is translated from the archaeological report: The Swedish National Heritage Board's Contract Archaeology Service, UV Öst, carried out a field evaluation in August 2002, and a final excavation in November the same year. The surveys covered remains of an Iron Age settlement by Stora Ängård, Lambohov, Slaka parish in Linköping municipality, Östergötland County, and were brought about by the municipality's plans of constructing a residential area with single-family houses on the location. The area is rich in ancient monuments and archaeological remains and the excavation was carried out nearby graves, stone fences and abandoned fields. The remains found were post holes, hearths, pits, pit systems and finds such as pottery, burnt clay, burnt bones and quartz. The investigations have shown that the site goes back to the Early Roman Iron Age and the Migration Period.

Purpose:

The information in the purpose is translated from the archaeological report: The purpose of the field evaluation was to form an opinion of the type, intensity and extension of the archaeological remains found during the preceding survey, and date them if possible. The purpose of the final excavation was to document, date and interpret the features and structures. The result of the investigations will be seen in an Early Iron Age perspective, with a starting point in the known archaeological remains and previous surveys carried out in the area.

The ZIP file consist of GIS files and an Access database with information about the excavations, findings and other metadata about the archaeological survey.

This layer represents the OIT Community Anchor Institutions (CAI) data set. ''Community Anchor Institutions'' consist of schools, libraries, medical and healthcare providers, public safety entities, community colleges and other institutions of higher education, and other community support organizations and entities. These locations may not offer broadband availability to the public (although most libraries and many schools, and community centers do) but offer an opportunity for policy makers to understand where community anchor institutions which have broadband access are located; this can help in identifying challenges and opportunities to reaching connectivity goals. Although it is constantly being improved upon, ultimately we aim for this data set to evolve into a reliable resource for emergency response services.

Web Map Services - Please note that the endpoint below also offers links for JSON, SOAP, WMS, and WFS. Additionally, the "Google Earth" link allows the user to download a KMZ file representative of the CAI data set.

The statewide composite of parcels (cadastral) data for New Jersey was developed during the Parcels Normalization Project in 2008-2014 by the NJ Office of Information Technology, Office of GIS (NJOGIS.) The normalized parcels data are compatible with the NJ Department of the Treasury system currently used by Tax Assessors, and those records have been joined in this dataset. This composite of parcels data serves as one of the framework GIS datasets for New Jersey. Stewardship and maintenance of the data will continue to be the purview of county and municipal governments, but the statewide composite will be maintained by NJOGIS.Parcel attributes were normalized to a standard structure, specified in the NJ GIS Parcel Mapping Standard, to store parcel information and provide a PIN (parcel identification number) field that can be used to match records with suitably-processed property tax data. The standard is available for viewing and download at https://njgin.state.nj.us/oit/gis/NJ_NJGINExplorer/docs/NJGIS_ParcelMappingStandardv3.2.pdf. The PIN also can be constructed from attributes available in the MOD-IV Tax List Search table (see below).This feature class includes a large number of additional attributes from matched MOD-IV records; however, not all MOD-IV records match to a parcel, for reasons explained elsewhere in this metadata record. The statewide property tax table, including all MOD-IV records, is available as a separate download "MOD-IV Tax List Search Plus Database of New Jersey." Users who need only the parcel boundaries with limited attributes may obtain those from a separate download "Parcels Composite of New Jersey". Also available separately are countywide parcels and tables of property ownership and tax information extracted from the NJ Division of Taxation database.The polygons delineated in this dataset do not represent legal boundaries and should not be used to provide a legal determination of land ownership. Parcels are not survey data and should not be used as such. Please note that these parcel datasets are not intended for use as tax maps. They are intended to provide reasonable representations of parcel boundaries for planning and other purposes. Please see Data Quality / Process Steps for details about updates to this composite since its first publication.***NOTE*** For users who incorporate NJOGIS services into web maps and/or web applications, please sign up for the NJ Geospatial Forum discussion listserv for early notification of service changes.

For continuity, many MDP parcel boundaries found in MDOT SHA Planning Level Right-of-Way (Tax Map Legacy) have been incorporated into MDOT SHA Right-of-Way data with an "Estimated" quality level. Please see below for a description of the primary attribute.-----------------------------------------------------The polygons in this layer are divided into 318 arbitrary grid zones across the State of Maryland. Updates to the parent ROW boundary line data set [MDOT SHA Right-of-Way (Secured)] are made by grid and reflected in this polygon layer.For more information or to report errors in this data, please contact MDOT SHA OIT Enterprise Information Services:Email: GIS@mdot.maryland.gov
