Adjusting image positions in Agisoft Metashape with ASPSuite local coordinate transformation

ASP Suite has the ability to adjust camera positions based on a local coordinate system. These positions are not updated in the EXIF data, but placed in a file in the “PPK” folder from the ASPSuite project. To import this file into Agisoft Metashape, please follow the instructions below: Open Metashape and import project images.…

LP360 Surface Methods

The surface method defines how z or elevation values are determined when exporting a surface or comparing control points to a surface. Each surface method implements a different way of interpolating elevations from LIDAR points. The following describe the surface methods in more detail. Triangulation (TIN)TIN (Triangulated Irregular Network) partitions a surface into a set…

Intensity – Point Insertion vs Triangulation

When generating intensity rasters using the LP360 Export Wizard or LDExport one has the option of generating the raster using Point Insertion or Triangulation surface methods. Surface Method Type: Triangulation Point Insertion Description Generates a Triangular Irregular Network (TIN) and probes the center of each cell for an interpolated value from the triangulated surface. Finds…

Recovering missing Inspire 2 camera events with DAT workflow

When performing flights with the Inspire 2 and I2 personality cable (SD cable), it is always best to snap ground photos before take-off and verify that events are being recorded (GNSS light blinks). If the GNSS light does not blink when the ground photos are taken, this means the photo positions are not being recorded…

Viewing two trajectories side-by-side in ASPSuite

Sometimes it is useful to view two flight trajectories side-by-side to ensure the correct amount of coverage is achieved. The following steps explain how to open to solutions in ASPSuite’s diagnostic window. Note: These steps assume the user has processed two flights through ASPSuite so that a pos file has been create for each flight.…
