The ASPRS has released new accuracy standards for geospatial data, taking into account the techniques and accuracies of modern mapping tools.
In a press release, the American Society for Photogrammetry and Remote Sensing (ASPRS) observed that the previous standard was unchanged since 1947 when totally different surveying techniques were in use.
‘The new ASPRS standards,’ the organization said, ‘address recent innovations in digital imaging and non-imaging sensors, airborne GPS, inertial measurement units (IMU) and aerial triangulation (AT) technologies.’
An attempt had previously been made to update standards with the 1990 ASPRS standards, but while they were an improvement, ‘they did not do well in representing the capabilities of LiDAR, orthoimagery, digital mapping cameras or other current technologies in widespread use today.’
The new ASPRS standard is designed to be technology-, scale- and contour interval-agnostic and ‘address higher levels of accuracies achievable by the latest technologies (such as unmanned aerial systems and LiDAR mobile mapping systems)…Finally, the new standards provide cross references to older standards, as well as detailed guidance for a wide range of potential applications.’
At PhotoSat we’re happy to adopt these new standards but where exactly do we fit in? We’re not photogrammetrists, nor LiDAR processors. In fact, we have invented a new technology for processing stereo satellite photos! Regardless, we provide satellite elevation mapping with vertical accuracies better than 30cm RMSE in areas of sparse vegetation. And we’ve published many proof of accuracy studies to prove it.
