LAS 1.4 Specification Approval22/11/2011 |
| The American Society for Photogrammetry and Remote Sensing (ASPRS, USA) has announced LAS 1.4, a new release of the open file format for Lidar data storage and delivery. The most significant of the new features include expansion of the Class field from 32 to 256 classes; Well Known Text (WKT) encoding for coordinate reference system designation; support for scanner designation for multiple sensor laser systems such as mobile mappers; support for up to 15 return pulses for discrete pulse systems (waveform support was added at release 1.3) and maximum file size increased from 4 GB to a theoretical file size of 18 Exabytes. |

According to James Plasker, ASPRS executive director, the adoption of WKT as the standard method of representing coordinate reference systems brings LAS in line with evolving GIS standards and ensures a method of accurately representing both horizontal and vertical references. The expansion to 256 classes will allow more robust representation of complex collection environments such as electric transmission line modeling.
The LAS version 1.4 specification was approved by the ASPRS Board of Directors on 14th November 2011 and is available for immediate use. The full specification can be downloaded from the ASPRS website.

Using Total Stations for Indoor Radiation Mapping |
|
A total station can be used for many applications. Oak Ridge Associated Universities (USA) uses a total station for indoor radiation characterisation, which enables the team to better perform environmental assessments. This video shows how it is done.
