AUTHORS: Ted Covill, WSP USA Inc

ABSTRACT: What are accuracy Standards? The U.S. Bureau of the Budget published the United Stated National Map Accuracy Standards in the 1940's. These standards were updated through-out the 1940's but remained unchanged until the 1990's when the American Society for Photogrammetry and Remote Sensing (ASPRS) published the ASPRS Accuracy Standards for Large-Scale Maps. The ASPRS Accuracy Standard was based more on real world positioning accuracy rather than an accuracy that is based on paper maps. Over the years new standards have been published by other agencies such as Federal Geodetic Data Committee, FEMA and the ASPRS to reflect the advances and introduction of new technologies. In 2014, the ASPRS introduced their new standard with the intent of condensing and override previous digital geospatial standards. These standards are often confusing and misunderstood. This presentation will attempt to explain the differences between the standards and how the standards relate to each other. We will discuss how the accuracy standards relate to the current data sets_x000D_being utilized in the geospatial community such as orthophotography, planimetric mapping, Digital Terrain Models (DTM), contours, LiDAR and Unmanned Aerial Systems (UAS, A.K.A. drones).
