When would one use Out Areas in Breakline Enforcement?

Out areas are used to create void areas in the TIN, resulting in No Data values in the exported DEM raster. One may wish to do this for: Waterbodies Perhaps for sensitive areas To not generate contours in the interior of buildings If the project area is a corridor or oddly shaped, then one can…

Ephemeris and Navigation Data Files

During processing in ASPSuite, two files are obtained as part of the “Auto-download” step on the ephemeris tab: an ephemeris (sp3) file and a broadcast (brdc*.YYn) navigation file. ASPSuite version 2017.2.77.0 and earlier only display (and allow browsing) to the ephemeris file. Version 2017.2.78.0 and later allow both files to be browsed or auto-downloaded. If…

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,…

Breaklines in LP360- Part 4

This is the fourth edition of our series on breaklines in LP360. In this edition, we will have a look at how features are represented in LP360 as well as the tools available for collecting “flat” breaklines. Features: Features in LP360 are internally stored as files in Shape format. This is a binary standard developed…

Error getting feature geometries (GetFeatureGeometries)

Problem: While trying to select a feature in LP360 using the Feature Edit tools a user receives an error message, “Error getting feature geometries (GetFeatureGeometries). Exception information: HRESULT: 0x80004005. Description: Unable to convert shape using ShapetoLPGeometry.” The message indicates that the type of feature being selected is not supported in that version of LP360. Probable…
