The ILMF 2013 conference opened with a packed room (300+) for the ASPRS Hot Topics session. Lewis Graham explained the LAS Validator Suite project which he hopes will be completed in the next 6 months. The software will be open source, but modifications will not be allowed. The software will simply provide a pass or fail response. There will not be lot of diagnostics. They are looking for contributions from the industry. Lewis all presented a short discussion of deriving 3D point clouds from imagery. This has applications for the use of UAVs.
The ASPRS Mobile Mapping committee reported that 2 people have been working on developing a draft document for a standard. They are using a swath-based approach for data QC that is similar to the methods used with airborne data where they analyze 9 parameters to assess the geometric agreement between adjacent swaths.
The afternoon sessions included two keynotes followed by dual tracks with 4 sessions each. The CEO of Pix4D explained that the quality of UAV imagery is low, but the redundancy can be such that it balances out to be roughly equal to a metric camera. Lawrie Jordan focused on a vision of a new GIS platform based on intelligent 3D images that can be analyzed using smarter software. He used Esri’s rule-based City Engine which now supports LiDAR data to provide examples of 3D simulation for storm surge.
The common them for the day was imagery-derived point clouds – not exactly what the LiDAR sensor vendors want to hear at a LiDAR conference I assume, but it is a hot topic.
