Binary Raster Files (*.flt)

As taken from the ArcView™ 3.2 Help System The Binary Raster File format is a simple format that can be used to transfer raster data between various applications. It consists of two files, the IEEE floating-point file and a supporting ASCII header file. The header file must have the same name as the data file,…

Add Raster Files to LP360

In the standalone version of LP360 one may add raster files using the ‘Raster Tab’ of the ‘Add Files’ dialog. Then navigate to the desired Raster file(s). The following are the currently supported raster file formats: TIF (*.tif) JPEG (*.jpg) PNG (*.png) GIF (*.gif) BMP (*.bmp) MrSID (*.sid) JP2000 (*.jp2) ECW (*.ecw) IMG (*img) Binary…

Rail Extraction Tools in LP360

LP360 includes tools to automatically extract a rail alignment (centerline) feature as a polyline as well as classify “top of rail” from LAS files derived from Laser Intensity Detection and Ranging (LIDAR) points.  This feature is implemented as a semi-automated Point Cloud Task (PCT) and is available in the Advanced version of both LP360 for…

Draw operation failed for at least one layer (23021)

Symptom: Receive a message in the lower left corner of LP360 indicating that the “Draw operation failed for at least one layer (23021)”. Probable Resolution: At least one of the layers in your Table of Contents (TOC) is a WMS layer but your project layer has no Current Coordinate System (SRS) or an unknown Current Coordinate…

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…

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,…

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…

Reproject/Shift LAS PCT in LP360

This workflow is for reprojecting, shifting, or scaling in x, y, and/or z direction, for LAS data. This is useful for converting: Geographic Spatial Reference System (SRS) to Projected SRS and vice versa. Projected SRS to another Projected SRS Different measurement units: US survey feet, international feet and meters. Removing vertical bias from LAS data…

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…
