GeoCue’s repository of TrueView tools, tips and workflows for the TrueView line of drone mapping products. Includes former AirGon products such as Loki and ASPSuite.
Agisoft’s Metashape (formerly Photoscan) has capabilities for editing orthomosaics. One function is to assign only user selected images for a specific area. This is useful for cleaning up areas of the ortho that have: blurriness, moving vehicles, bad image stitching, etc. Created polygons can also be used for defining a subset of the project area…
When generating a DEM in LP360 / True View Evo for import into CAD software, there are a few nuances to consider. Unlike the commonly used LandXML CAD surface format, the DEM format will only enforce breaklines at the resolution of the generated raster. In order to properly enforce and display the breakline areas, you…
Civil3D has known import DEM issues. The user may notice a systematic shift related to units or grid positioning mismatch when comparing the imported DEM to other data in Civil3D, such as the breaklines that were also generated in LP360/True View EVO as part of the . Note: Depending on the scenario, the user may…
Under normal circumstances, LAS files only need have pyramids generated during initial import into LP360/True View Evo. However, there are times when the user must rebuild LAS file pyramids after performing specific LP360 tasks. This article will review the method used to update pyramids, as well as the known tasks which will precipitate the user…
While LP360 can handle a practically unlimited amount of LIDAR data, individual LAS file sizes must be kept small. LP360 and True View Evo have a maximum recommended individual LAS file size to optimize performance and functionality of the software. If the size of any LAS file used exceeds a recommended size of 250 MB,…
The Affine Transform LAS Point Cloud Task is a versatile tool for modifying the coordinates of your point cloud. A common use is applying grid to ground conversions which require more than a simple scale or translation. How to setup the Affine Transform LAS Point Cloud Task to accomplish this may not be readily apparent…
For certain projects, it may be necessary to process and output derivative products in a user defined (local) coordinate system. There are multiple ways to accomplish this, but one is to have matching pairs of projected and local coordinates to define a local coordinate system and derive the transformation. If the rotation, scale and translation…
LAZ is an open source compressed file format useful for more efficiently storing point cloud data than the LAS file format. It is strictly a storage format and must be converted to LAS before it can be used for processing or analysis purposes as the format does not allow for direct edits. Files in the…
