ASPRS (American Society for Photogrammetry and Remote Sensing) LAS Specification defines the attributed that can be stored in each point data record format (0 through 10). This article provides a summary as to which attributes can be stored in which format. Read more...

A borrow pit is an area where soil and/or rock is removed, added or both for use at some other location (for example, in obtaining fill dirt for highway construction projects). Learn how to monitor the amount of material change in the pit (volumetric change). Read more...

A portion of the QA/QC process should be to determine what the Coordinate Reference System (CRS) or Spatial Reference System (SRS) is for the LIDAR data. Both horizontal and vertical CRS should be determined as part of the QA/QC process. This check ensures that the data has the correct information assigned within the header of the LAS files.

Contours are polylines that are used to connect locations of equal value and show how values change across a surface model. When talking about contours it is not uncommon to hear about Engineering Contours versus Cartographic Contours. The question becomes what is the difference between the two? Read more...

LP360 currently provides four options for thinning the bare earth dataset to allow you to take it into those other software packages. Read more...

We have had a lot of things going on in August 2015 from finalizing a new client interface for LIDAR Server to receiving our Section 333 Exemption from the FAA. In addition we have started a new workflow integration project that will see a major image processing system hosted in Amazon Web Services Read more...

In order to accurately complete an aerial LIDAR survey it is important that the sensor is properly calibrated. Airborne LIDAR calibration can be a complex and daunting task. TerraScan and TerraMatch are a wonderful toolset to assist the analyst in determining and correcting these systematic errors. Read more...
