Uncompress the zipped shapefile to a folder on your computer and you should be able to use the shapefile in your mapping application.
Parcels is a polygon dataset the represents the approximate boundary of each parcel in the town updated through September 2015. The data were created from a set of tax maps maintained by the Old Saybrook Assessor. The original tax maps were not drafted on an accurate base. Users of these data should be aware that the parcel boundaries include positional inaccuracies and the data should be used ONLY for general planning purposes.
Buildings is a polygon dataset that includes the approximate outlines of all buildings greater than 200 square feet in size. The data, produced by Photo Science from ortho imagery acquired in April 2012, were developed using automated image segmentation software. Since 2012 new commercial buildings have been added to the dataset from scanned and georeferenced as-built survey maps.
Roads is a polygon dataset that includes the paved area of roads throughout the town. The data, produced by Photo Science from ortho imagery acquired in April 2012, were developed using automated image segmentation software.
Impervious Features is a polygon dataset that depicts the locations of impervious features other than roads and buildings. Included in this dataset are features such as parking lots, driveways, sidewalks, patios, etc. The data, produced by Photo Science from ortho imagery acquired in April 2012, were developed using automated image segmentation software. Since 2012 new commercial impervious features have been added to the dataset from scanned and georeferenced as-built survey maps.
Road Centerlines is a line dataset that includes the approximate center of paved and unimproved roads in Old Saybrook. The road centerlines were created by adjusting 911 road data to match the centers of roads as shown on high-resolution April 2012 color ortho imagery. Attributes include the road name and a Census Feature Classification Code (CFCC). CFCCs were edited to correct errors in the original classifications and to create a uniform classification system for the town.
The Community Facilities and Open Space dataset includes properties owned by the town of Old Saybrook and other conservation organizations that are preserved as open space for habitat and recreational uses. The dataset also includes properties owned by the town and other organizations that are used for community purposes (e.g. schools, library, Town Hall, etc.). Data are current to June 2016.
