Ground targets for horizontal check for LIDAR data collection

An important evaluation to make when performing a QAQC analysis of a LIDAR data set is a control point comparison. Typically, this refers to checking the vertical accuracy of a LIDAR data set. In regards to vertical check/control point location: “Unlike horizontal checkpoints, vertical checkpoints are not necessarily required to be clearly defined or readily…

Make your Raster Files display faster in ArcMap

Problem: If you have an older computer with older display drivers then you may notice that every time ArcMap refreshes a raster view, there is a noticeable ‘flash’ as the display updates. This ‘flashing’ can become quite annoying and slow down your processing. Probable Resolution: ArcMap does have a hardware acceleration option for supported layers.  If…

Geometry not within read/write loaded point extent (10075)

Problem: Receive either a “Classify is Complete” or a “ClassifyByGeometry function fails” with an overall message, or by feature messaging, indicating “Geometry not within read/write loaded point extent (10075)”. Probable Resolution: The warning message indicates that the LAS files intersecting with the indicated feature are not open for read/write, hence, no classification based on that…

GeoCue Adds Project Archiving in v2017 Release

One of the common requests we receive from our GeoCue users is to add the ability to archive or off-line projects when they are completed.  Once a project has been completed and fully delivered to the customer, it needs to be transferred effectively out of production operations to an enterprise data archive.  Archiving a completed…

Creating project blocks for a corridor

Building a Simple Corridor We will use an example of building a road corridor.  For this exercise, we have created a new project in the NAD 83, Zone 16 N meters horizontal coordinate system and ellipsoid, meters for the vertical system.  To this project we added a reference raster layer and imported the Madison County…

Cookie-cutting by Polygons

Sometimes it may be useful to “cookie-cut” LIDAR points by polygons. The polygons may represent rectangular grids, such as quarter quads, or can be irregularly shaped. Cookie-cut allows you to use a shape file of one or more polygons. An attribute from the Shape file can be used to name the various files. This is set…

Command Line Executable for Point Cloud Information

A quick and basic way to get information about projection information, GPS time and the number of points within an LAS file is to run the LDDump executable. The program is designed to pull the information directly from the public header block of the LAS file, provided the header has been correctly populated with 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…
