Below are links to GIS data available for download. The date in parentheses next to a data set indicates the most recent date that data has been updated:
Available GIS Data
The County has paper and electronic (PDF) copies of aerials from 1938, 1952, 1957, 1964, 1972, 1973, 1977, 1980, 1986, 1988, 1990, 1996, and 2003. To obtain (via e-mail) or view copies of the aerials, please contact the Office of Planning & Zoning. For more recent years, please see the "orthophotography" section below.
Lidar Data and Topography (2014)
In 2014, Cecil County Government sponsored the collection and processing of new lidar data for the entirety of Cecil County. Deliverables included las files, digital elevation models, digital surface models, spot elevations, and one foot contours. To obtain this data, please contact the County's GIS Coordinator. If approved for receipt of the data, users will be required to complete and sign a third party use form. Additionally, a 1TB external hard drive must be provided by anyone approved to receive the entire dataset. If only interested in a portion of the County, please use the lidar index map to determine which lidar tile to request. Due to the voluminous size of the data, please allow for a two business day turn around for processing.
Scans of all major subdivisions are available from the Maryland State Archives' "Plats.Net" retrieval system.
The Office of Planning & Zoning has scanned all 4,100+ minor subdivisions that were approved between April 15, 1976 and the present day. The subdivision plats may also be downloaded from the County website.
Orthophotography (2005, 2008, 2010, 2013, and 2016)
Orthophotography from 2005, 2008, 2010, 2013, and 2016 is available from the Office of Planning & Zoning. Taken as part of a statewide project (2008) and an eastern shore project (2010, 2013, and 2016), this photography is in the public domain. However, due to the large size of the various files, individuals must provide County staff with an external hard drive having at least 400 GB free space (and advance notice) in order to obtain this data. Due to their large file size, individual tiles are unable to be e-mailed.
In late 2008, Cecil County completed development of a County-wide vector parcel geodatabase. Said geodatabase is updated monthly (both in terms of parcel geometry and parcel attributes), and it is available as a GIS Service via Cecil Maps, Cecil County's online GIS application.
