The Blount County GIS Group has two types of digital imagery available for purchase: Oblique and Orthophotos.
Oblique imagery is an aerial photograph that has been captured with the axis of the camera held at an angle between the horizontal plane of the ground and the vertical plane perpendicular to the ground. The oblique image is typically captured at a 40° angle which allows for a more natural perspective so that objects are easier to interpret and recognize.
Oblique imagery for portions of Blount County was captured in 2007, 2009, and 2013. The imagery is provided in a jpeg format.
Orthophoto is an aerial photography from which distortions owing to camera tilt and ground relief have been removed. An orthophoto has the same scale throughout which allows for accurate measurements to be taken, and for it to be used as a map.
Orthos for Blount County were captured in 2002, 2007, 2009, 2011, and 2013.
Blount County offers elevation data derived from a Digital Elevation Model (DEM). The DEM was generated from point cloud data captured during the County’s LiDAR acquisition in March 2015. A point cloud of bare-earth x, y, z coordinates is used to create topographic contour maps.
Blount County offers contour data at 2′ intervals, and are disseminated based on the Property Assessor’s 100 scale and 400 scale grid index.
The Blount County E911 Communications (Blount 911) center is the street and address authority for Blount County and is responsible for assigning all street names and addresses. Blount 911 has developed a database based on the State of Tennessee’s Tennessee Information for Public Safety (TIPS) database, and uses it to maintain street and address information within the county.
The street centerlines are a linear representation of the street and contain information such as street name, to and from block ranges (left & right side of the street), zip code (left & right side of the street), city (left & right side of the street), and more.
