Adding additional Geoid definitions to LP360

LP360 has a wealth of supported vertical datums available to the user. However, there are some vertical datums, or specific geoids, not present in the current database (e.g. NAVD88 – Geoid 18). If the imported data is already in the desired coordinate reference system (CRS) using a Geiod not present in the LP360 database, the…

Point Cloud Tasks

Point Cloud Tasks What is a Point Cloud Task (PCT)? A function (Extract ground, Conflate Line) that operates on points and/or vectors. A task can be a filter and/or an extractor. A filter classifies or changes the classification values for points (e.g. classify ground). An extractor extracts information from the point cloud data into vector,…
