The Maryland State Geographic Information Committee (MSGIC) aims to promote ongoing projects throughout the state and to inform the greater community. We hope to highlight the accomplishments of the various entites throughout the MSGIC community, reduce duplicative efforts, and by providing contacts on these projects, assist in the sharing of lessons learned. If you have a project, or know of one, big or small, contact email@example.com .
Over the years, staff at the National Capital Region Transportation Planning Board (TPB) has collected transportation data from various sources, primarily member jurisdictions, state agencies, and transit authorities. This web application was developed to improve access and data sharing between TPB Members and other authorized users in the region. This application was developed utilizing ArcGIS Server (version 10.2.1) and the ArcGIS Viewer for Flex (version 3.6 as of May 2014). The application contains two primary types of web services: map services and geoprocessing services. The datasets contained within the application are maintained using ArcGIS.
This application interface was designed for viewing, querying, and downloading data—but not for creating maps. Users are encouraged to utilize the application to obtain the spatial and tabular data necessary for their purposes for use in ArcGIS
or other software. (Taken from intro of the RTDC user’s guide/splash page)
This leaf-off 2014 project had contributed funding from DNR and SHA with Federal funds and has captured Quality Level 2 LiDAR data. Data with be delivered to USGS for quality assurance in October 2014. Deliverable products include: Metadata, raw .las points, bare-earth .las points, intensity returns, 1-meter grid DEM.

“This Mapping Update will allow local Critical Area maps to be incorporated into the “Maryland iMap System,” facilitate access to official Critical Area Maps via the internet, use current aerial imagery as a base map, and reflect current shoreline and wetland conditions. The resulting Critical Area Maps will provide a uniform, consistent, and seamless map product that can be easily updated. As part of the mapping update, the legislation required the Critical Area Commission to implement a pilot project in two counties in order to develop a mapping methodology that could be applied throughout the Critical Area. The counties selected were Baltimore County and Talbot County.” (Taken from splash page)
The National Geodetic Survey (NGS) is preparing new horizontal and vertical datums for release in 2022, as part of the NGS Ten-Year Plan.
What does this mean for MSGIC? MSGIC is advocating education about the new datums and engaging the community by forming a sub-committee on New Datums. Executive Committee member Matthew Webb will head this subcommittee, which will guide MSGIC through the change, as we go from today to 2022. The sub-committee intends to help educate and prepare the community for this change through several possible formats and resources, such as newsletter articles, updates, presentations, workshops. As part of the Spring 2014 MSGIC Quarterly Meeting, Mr. Dave Doyle made a presentation on Modernization of the National Spatial Reference System.
