When classifying within LP360, the numbered keys on the number pad section of the keyboard can be used to specify and commit points for the “To” class during the classification process. However, the numbered keys across the top of the keyboard cannot be used for this shortcut. Classes 0-9 (Unclassified – Water) can be classified…
After LIDAR data has been collected and delivered to the processing office one of the first steps, after quality control and calibration, is to run classification routines on the data. There are multiple classification routines, which may be used depending upon the final delivery results of the data, however generally a ground classification routine is…
AirGon Reckon (“Reckon”) is our cloud hosted collaboration portal for small Unmanned Aerial System (sUAS) or “drone” mapping. It has been designed from the ground up for scalability in the cloud. Hosted in Amazon Web Services (AWS), it provides a robust platform for sharing data that requires no administration or infrastructure on the user’s part…
In TerraScan the Time conversion can convert to/from GPS seconds-of-week, GPS standard time and GPS time. Projects can store GPS seconds-of-week, GPS standard time and GPS time in LAS 1.2, and later formats, or Fast Binary. ‘GPS seconds-of-week‘ time stamps are between 0 and 604800, where the clock resets at midnight Saturday night to Sunday morning.…
When designing block boundaries in TerraScan it is necessary to break the dataset up into manageable block sizes. Depending on the task you wish to perform on the dataset you may desire different block sizes, but from an overall perspective one can recommend the following as general guidelines. 32-Bit (v8, v8i) 64-Bit (CE) Recommendation 20…
In some cases one may have received the tower locations from the power line company prior to flying the survey. These points may be read into TerraScan and used as a shortcut for generating a Tower String for use as the Active Power Line rather than having to manually collect the string. The text file…
Before running Detect Wires it can be helpful to clean up the potential wire points to help prevent false positives from being detected. The Classify Above/Below line tool can be useful for this, however, the View Tower Spans contains an additional classification tool Classify Above/Below Curve which can be more efficient. The Classify Above/Below Curve tools…
When using the power line tools in TerraScan the activated power line may obstruct the view. In the TerraScan -> Settings -> Powerlines -> Active Line setting you have the option that controls the highlight of the active line in the display. There are three options: No hilite, Vertices, and Line Segments. Line segments is…
Adding RGB Attributes There are often times when a user may wish to extract RGB values from imagery in order to assign a color value to the each LIDAR point. In assigning the RGB attribute, the LIDAR file’s Point Data Record Format(PDRF) needs to change in order to accommodate the additional values. A TerraScan Project…
