GI_Forum publishes high quality original research across the transdisciplinary field of Geographic Information Science (GIScience). The journal provides a platform for dialogue among GI-Scientists and educators, technologists and critical thinkers in an ongoing effort to advance the field and ultimately contribute to the creation of an informed GISociety. Submissions concentrate on innovation in education, science, methodology and technologies in the spatial domain and their role towards a more just, ethical and sustainable science and society. GI_Forum implements the policy of open access publication after a double-blind peer review process through a highly international team of seasoned scientists for quality assurance. Special emphasis is put on actively supporting young scientists through formative reviews of their submissions. Only English language contributions are published.

Starting 2016, GI_Forum publishes two issues a Year.

Abstract

This presentation describes a new solution for geospatial Geiger-mode Avalanche Photodiode (GmAPD) LiDAR – a suite of sensors, processing tools and analytics born from a 15-year GmAPD legacy within certain DoD environments that will bring a significant increase in production efficiency to the commercial market. The objective of the sensor design was to support USGS LiDAR Quality Level 1 (and higher) data production over large areas from pressurized, fixed-wing aircrafts flying at altitudes of between 4 km and 10 km AGL. Topics to be covered include: 1) why GmAPD sensing is a significant advance in LiDAR collection efficiency, 2) how the ITI-1000 GmAPD LiDAR sensor supports cost-effective, wide-area, high-density collection, with coverage rates much greater than 1,000 km2/hr, and 3) how a high-volume production system, including noise reduction and photogrammetric registration techniques, is designed to reduce the production time for the GmAPD 3D point clouds while increasing data accuracy.

Keywords: Geiger-mode LiDAR sensor; avalanche photodiode detector; production system; photogrammetry; point clouds
