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.
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…
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…
We do a significant amount of Research and Development (R&D) in drone mapping. Our AV-900 rotary wing system has an L1/L2 Global Navigation Satellite System (GNSS) that we run in the Post-Processed Kinematic mode. This gives us the location of the AV-900 Survey System antenna to within a few centimeters relative to a local base…
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…
We have lot of LP360 customers with a variety of disparate feature collection and editing needs. To begin to address these needs, we introduced a completely new set of Feature Edit tools in the 2016/2017 releases of LP360 (standalone). Last month I introduced the new Feature Analyst tool that will be available in LP360 2017.1…
Problem: When loading an orthophoto image into LP360/Topolyst no image is displayed, yet when you zoom in it becomes visible. Modifying the LP360 image display properties shows the image extents properly and the header checks out. Probable resolution: We suspect that the overviews in the image file are corrupt/invalid. One can use the GDAL tool to…
Feature Analyst is an exciting new tool that will appear in LP360/Topolyst 2016.2. To motivate this discussion, I will provide a synopsis of a few use cases for Feature Analyst here. A detailed look at these cases is presented at the end of this article. Examples of tests you will be able to perform with…
Calibrate IMU and Compass after updating new firmware for AV900 If AV900’s firmware is updated, it’s recommended that the IMU and compass should be re-calibrated. Here are the step-by-step instructions to re-calibrate them: Prepare the Drone Insert and secure the battery into the AV900 Raise and secure the GPS/Compass (fig. 1) Figure 1. The GPS/Compass must be…
Reckon has been deprecated and replaced by LP360 Online, including the LP360 Portal and LP360 Cloud. This workflow explains how to create a redline in Reckon. Redlining provides the ability to create, edit and publish geometries with attributes. Redlines can be used to communicate work to be done with a service provider (i.e. defining stockpiles…
