<p>The Mid-Atlantic region is predicted to have some of the worst impacts of Sea Level Change (SLC) because of the combination of rise, subsidence, and relative position to the North Atlantic Gyre. With 3,190 miles of coast, Maryland SHA is prioritizing and mitigating the potential impact of SLC on SHA assets, as well as the increased impact of coastal flooding that will result. Using SLC projections, USGS studies, and NOAA tidal observations, the ESRGC provides SHA forecast intelligence on 2015, 2050, and 2100 scenarios, helping protect Maryland’s long-term investments.</p><p>The data may be used and redistributed for free but is not intended for legal use, since it likely contains inaccuracies.

<p>To better inform Maryland's state delegates and senators about the land use issues in their district as well as to provide them with a useful reference map to use during discussions with constituents, the ESRGC has completed a project to create a large format map of land use for each 2022 state legislative and congressional districts in Maryland. These maps were given as gifts to the senators and delegates in January 2023, with the compliments of Salisbury University, the MidShore Regional Council, the Tri-County Council of the Lower Eastern Shore of Maryland, and the Upper Shore Regional Council.</p><p>The maps have a dimension of 24 " x 36 ", and are in .pdf file format. Adobe Acrobat Reader is required to view and print these maps. If you do not have Acrobat Reader, you can download it for free at www.adobe.com. Although the size of these files are larger than most printers can print, they can be printed in the standard size of 8.5" x 11" by selecting the "Fit to Paper" option under the "Page Scaling" drop-down menu.</p><p>To order a Legislative or Congressional District map in its full printed size (24" x 36"), please contact the ESRGC at esrgc@salisbury.edu. Include in the email what district(s) you are requesting, whether its Legislative or Congressional, and the quantity. The prices for printed maps are: $35 each or $55 if laminated, plus $9.95 shipping and handling up to 5 maps (allow 5-7 business days).</p><p>*56k Warning: The size of the District maps are voluminous and may require a high-speed internet connection to download and view.</p><p>The source of the data contained within these maps was provided by the Maryland Department of Planning and the Maryland State Highway Administration.</p><div class="raw-html-embed">

Legislative and Congressional District Maps (2022)

<p>The maps available for download on this page represent the areas served by broadband for each county in Maryland as collected by the Maryland Broadband Mapping Initiative (MBBMI), current as of June 30, 2014. The MBBMI was part of a nationwide five year National Telecommunications and Information Administration project to map broadband availability. During this time the Maryland Broadband Cooperative, assisted by the ESRGC and Center for GIS, collected data from broadband providers including the location service, technology of transmission, and download/upload speed. At the time the FCC and NTIA defined broadband as greater than or equal to 200 kbps download. As a national project, census blocks were selected as the smallest continuous geometric layer to identify areas served by broadband providers. The ESRGC used 14 verification methods to test the data received from broadband providers, however, there are a number of issues that may result in misrepresentation of the data for Maryland, including, (1) any census block with one served location was considered served; (2) census blocks greater than 2 square miles were delivered as road segments and then converted to census blocks; and (3) any location currently unserved by a provider but could be served within 5 to 10 business days was accepted as a served location.</p>

<p>Recently, there has been an increasing interest in linking the locations Smith placed on his 1612 map with their corresponding present-day coordinates using sophisticated digital mapping and spatial statistical analysis. The upcoming anniversary has created a desire to retrace the route that Smith took as a tribute to him and his cadre of explorers as well as the hope that some of the more out-of-the-way places around the Bay might garner more interest in their towns and villages with a link to 400-year old history. The Town of Vienna on the Nanticoke River in Dorchester County , Maryland fits this description. Thus, the goal of this project was to scientifically compare the location of the town of Vienna with the mapped depiction of the Nanticoke River and its associated Native American villages as recorded by John Smith in 1608.</p><p>All datasets are in compressed .zip format. To download, click on a link and save the file to your computer. Extract all the files from the .zip file to an appropriate location on your computer. The resulting file will be a shapefile to which can be opened with GIS software.</p><p>If you have any questions and/or comments about the John Smith Datasets or documents, please contact the ESRGC at <a href="mailto:esrgc@salisbury.edu">esrgc@salisbury.edu</a>.</p>
