The 2022 York Region Business Directory contains just over 34,000 business listings. In the past, businesses were annually surveyed, either in person or by telephone to improve the accuracy of the directory. Due to the COVID-19 Pandemic, a survey was not complete in 2020 and 2021. The Region may return to annual surveying in future years, however the next employment survey will be in 2024. This listing also includes home-based businesses that participated in the 2022 employment survey. What is a NAIC code? The North American Industrial Classification (NAIC) coding system is a hierarchical classification system developed in Canada, Mexico and the United States. It was developed to allow for the comparison of business and employment information across a variety of industry categories. The NAICS has a hierarchical structure, designed as follows: Two-digits = sector (e.g., 31-33 contain the Manufacturing sectors) Three-digits = subsector (e.g., 336 = Transportation Equipment Manufacturing) Four-digits = industry group (e.g., 3361 = Motor Vehicle Manufacturing) Five-digits = industry (e.g., 33611 = Automobile and Light Duty Motor Vehicle Manufacturing) For more information on the NAIC coding system click here How do I add or update my business information in the York Region Business Directory?

    Description

    Maryland Roadway Centerline data consists of linear geometric features which represent the street centerline for all public roadways in the State of Maryland. The centerline represents the geographic location on the roadway between both shoulders (physical center), which often but not always coincides with the center painted line dividing bi-directional travel lanes. Roadway Centerlines data plays an important role in transportation management and planning, while also being the basis for all other roadway related data products. Maryland Roadway Centerline data is the end product of a statewide data sharing process between the Federal Highway Administration (FHWA), Maryland Department of Transportation (MDOT), Maryland Department of Transportation State Highway Administration (MDOT SHA), county governments and local municipal governments. Using a common centerline allows for better exchange of information related to the roadway system and provides opportunities for more efficient collection of information about roadway assets. Some centerlines were created in-house using imagery, GPS data, and MDOT SHA's Highway Performance Monitoring System (HPMS) database and others were received from county governments and updated in house using imagery, GPS data and MDOT SHA's HPMS database. The Centerline data includes annual HPMS updates / improvements submitted to the Federal Highway Administration (FHWA). Maryland Roadway Centerline data is needed for emergency response and management, routing buses and other vehicles, planning for land use and transportation needs, continuity of roadway data and display at county boundaries leading to the same "look and feel" across jurisdictions, tracking assets on and along the roadway network, producing maps at various scales, and numerous other applications. There are opportunities to make these processes more efficient, and this program addresses a shared foundation to solve some of these issues. This data is also used by various business units throughout MDOT, as well as many other Federal, State and local government agencies. Maryland Roadway Centerline data is updated and published on an annual basis for the prior year. This data is for the year 2017.

    Description

    The coastal recreation study is designed to establish a baseline characterization of participation rates and the economic value of coastal recreation and provide a spatial baseline of coastal recreation use patterns in the North Central Coast region. Please see the project report for full details on the data collection and analysis methods as well as a listing of survey questions. Included in this data package is a summary of all survey data as well as a PDF map depicting intensity of use across all coastal recreation activities data collected in the region. We also have spatial data for individual activities, including: Scenic enjoyment; Beach going (dog-walking, kite-flying, jogging, etc.); Photography; Watching birds and/or other marine life from shore; Sitting in your car watching the scene; Biking or hiking; Collection of non-living resources/beachcombing (agates, fossils, driftwood); and Swimming or body surfing in the ocean. If you would like to access the GIS data from this project please contact us. This dataset was originally uploaded to Oceanspaces (http://oceanspaces.org/) in 2013 as part of the North Central Coast baseline monitoring program. In 2020 the baseline data and reports were uploaded to the California Ocean Protection Council Data Repository by Mike Esgro (Michael.Esgro@resources.ca.gov) and Rani Gaddam (gaddam@ucsc.edu). Every attempt has been made to include all of the original data, metadata, and reports submitted in 2013, but please contact the Data Set Contacts with any questions.
