Display by Distance

Displaying points ‘by distance’ using TerraScan (version 016.022 and later) for MicroStation CONNECT  is different then previous versions. You will notice that the Display Mode option for distance is grayed out. This is because TerraScan no longer calculates distances on-the-fly. Instead, the Compute Distance command is used to make these measurements and stores that information as…

Reckon Tonnage Workflow

Calculating tonnage is a two-step process using Topolyst and Reckon.  First, the density information must be formatted and entered correctly into the “Volume” file in Topolyst/LP360.  This file can be named anything but for our instructions it is the Volume file you see in the figures below. Secondly, Reckon will calculate the tonnage from the…

Automatic Stockpile Toe Extraction

LP360 includes a Point Cloud Task (PCT) that will automatically digitize the toe of a clean stockpile and can allow for the classification of overhead structures such as conveyors.  This tool saves considerable time when computing stockpile volumetrics. A “clean” stockpile is one with a clear demarcation of the boundary from a 3D perspective that…

Terra License Usage

You can run Terra License Server when you want to view the status of the license pool or change the server settings. Terra License Server shows the current state of the license pool and logs every request and return event. The Licensed applications list shows a list of applications for which the program finds valid licenses…

A Quick Intro to Customizing MicroStation CONNECT

The biggest change when moving from one of the previous versions of MicroStation to CONNECT is that CONNECT is 64-bit program, allowing the advantage of access to more memory. Access to more memory enables Terrasolid to enhance their applications, and makes CONNECT much better suited for LIDAR and photogrammetric point cloud processing. The ribbon interface…

TerraScan Trajectories

TerraScan and TerraPhoto trajectory files may be generated in TerraScan by importing the following sensor trajectory file formats: Applanix SBET Sensor Trajectory Format Leica SOL Sensor Trajectory Format Riegl POF 1.1 Sensor Trajectory Format Topcon Trajectory Format (CTE) Novatel’s Inertial Explorer SBTC/SBIC sensor trajectory format Merge from GPS and INS ASCII files as defined in…

Hardware recommendations for faster processing

If you’re i/o bound, which is usually the case with LIDAR or photogrammetric point cloud processing, you need to figure out what kind of i/o you’re doing at the bottleneck. Case 1: If you’re just waiting for a single tile to load, your slowdown may be from low RPM HDD, but more likely you’re hitting…

Determining the correct Ephemeris File to Download from IGS

How to determine the correct Ephemeris File to download from IGS: First look at the OPUS report from the GPS unit. Find the highlighted info in Figure 1: Figure 1 Go to the IGS website: ftp://ftp.igs.org/pub/. Click on the GPS or GLONASS link as shown in Figure 2: Figure 2 For this example, I chose…

Exporting points in DGN Format

Point data can be exported into Bentley’s MicroStation design file format using the LP360 Export Wizard. LP360 uses a seed design file as the basis to create the new design file with the points in it. Hence, the working units of the seed file affect the generated point DGN file.  The seed file used by…

Geoid Adjustment in TerraScan

The elevation values of raw laser data and trajectories are often provided as ellipsoidal height values. Usually, these values need to be transformed into orthometric values of a local height system. For larger areas, the adjustment from ellipsoidal to orthometric height values can not be defined as one mathematical formula. Therefore, the elevation adjustment model…
