ASPRS announces new positional accuracy standards

SHARE

US: The American Society for Photogrammetry and Remote Sensing (ASPRS) recently released its new Positional Accuracy Standards for Digital Geospatial Data. The new ASPRS standards address recent innovations in digital imaging and non-imaging sensors, airborne GPS, inertial measurement units (IMU) and aerial triangulation (AT) technologies. Unlike prior standards, the new standards are independent of scale and contour interval, they address higher levels of accuracies achievable by the latest technologies (e.g. unmanned aerial systems and LiDAR mobile mapping systems), and they provide enough flexibility to be applicable to future technologies as they are developed. Finally, the new standards provide cross references to older standards, as well as detailed guidance for a wide range of potential applications.
