Interview with Chad Quinn, GIS Coordinator, City of O’Fallon Illinois Tell me about the City of O’Fallon (size, location, things you like about it and you think are special…). The City itself is less than 15 miles squared with a population of 28,281 as of the 2010 Census. We are located in the St. Louis…
We have a long history at GeoCue of working with companies and organizations from down under. Our LP360 for ArcGIS continues to find widespread adoption in Australian firms and government agencies, and our GeoCue workflow management suite is deployed to support production operations in the very active airborne LIDAR market in the region. However, this…
Final products can be exported from LIDAR data using either LP360 command line executables or the LP360 Export Wizard. Some export functions and resulting products include, but are not limited to: merging multiple LAS files into one LAS file, exporting LAS versions to different LAS versions, exporting from LAS to ASCII XYZ files, and exporting…
GeoCue has had a long association with the Pennsylvania State University (Penn State) where the John A. Dutton e-Education program in the department of Geography uses LP360 in their on-line LIDAR training program. Two of the instructors, Ms. Karen Schuckman and Mr. Mike Renslow, are very well known throughout the LIDAR and photogrammetry communities. Mike…
You can do part of a synoptic QA/QC on LIDAR data using either LP360 command line executables or the Point Cloud Statistics Extractor, which is one of the Point Cloud Tasks found within the LP360 GUI. Some general QA/QC information that can be gathered includes, but is not limited to, projection information, GPS time format,…
LIDAR data oftentimes requires preparation before further analysis can be completed on the data. LP360 has six command line executables which can be used for preparing LIDAR data before adding it to LP360 for Windows or the LP360 for ArcGIS extension. When installed in the default folder, these preparatory LP360 command line executables may be…
In the last edition of LP360 News, we discussed the creation of 3D breaklines for enforcing situations where the elevation must be a constant along the breakline. The most common example of this applications is “water body flattening” such as lakes and ponds. In this final installment of the breakline series, we will consider the…
In the last edition of LP360 News, we discussed the creation of 3D breaklines. Recall that, for our purposes, a 3D breakline is a vector that has an elevation value (Z) associated with each vertex. Generally, 3D breaklines can be divided into two categories – those with the same elevation for each vertex (used for…
Ever get frustrated trying to find one of your project LAS files in the LAS Files Table of Contents window? The Select LAS Files Graphically button is the tool you need. Simply click the Select LAS files graphically button and then select the LAS tile that you want to find. The corresponding LAS file is…
As we have discussed in the last two issues of LP360 News, breaklines are two- or three-dimensional graphic data (points, lines, polygons) that we introduce into an elevation model to alter the topology. When working with Geographical Information System (GIS) models, we nearly always model complex, irregular elevation data as a Triangulated Irregular Network (TIN).…
