Integrating LIDAR Data into ArcGIS Just Got Easier
by Susan Smith
Torin Haskell, director of Sales and Marketing for QCoherent Software, spoke with GISWeekly about the recentannouncement of LP360, the first LIDAR extension for the ESRI environment on the desktop. Haskell said that in the past, LIDAR vendors would provide ESRI users with multiple deliverables, “typically ASCII and grid files with different classifications and maybe unclassified data sets, delivered in tiles. People were working with possibly six different files per tile of data. With LP360, the user no longer has to ask for those deliverables. They can just ask for the
LAS files and thereby integrate all those products on the fly in ArcGIS.”
LAS files are the LIDAR standard which has been adopted by the ASPRS, and is published by that organization.
A relatively new company, QCoherent was born at the beginning of 2006, for the purpose of developing LP360. The code has been in development for a year and a half. “We felt there was a missing component with the huge ESRI marketshare, and so we have developed our first product for that platform,” Haskell explained. “We ultimately hope to go to other platforms as well". Below are some of the highlights of LP360’s impressive list of benefits and features:
- Virtually limitless data architecture – LP360 uses a pyramiding concept for accessing the LIDAR data from the binary LAS files. It is not memory dependent when it works with point data. “That’s been the major problem with people trying to use large point data sets in that it crashes their system and renders it basically inoperable due to the memory requirements for working with all these points,” said Haskell. “Our architecture removes that problem, and that’s why we can bring in these huge datasets and work with them in the ArcGIS environment.”
LP360 is on the desktop. “If you had to take these point data sets and bring them into ArcGIS or any other CAD or GIS package, it brings it to its knees. LP360 changes that paradigm so that you no longer have this performance issue associated with large point data sets.”
The costs accrued by city and county governments who pay for LIDAR data that they can’t use fully has been astronomical, Haskell said. People haven’t been able to work with the full point cloud. People can now program their own code to leverage against other data sets, to bring the data into a remote sensing scenario and use other data sets to classify or take advantage of the LIDAR data they’ve paid for.
- Integrated extension for ArcMap and ArcCatalog: Previously LAS was not an accepted data layer in ArcCatalog, and you wouldn’t see it there. Now, as you go through ArcCatalog, you have the functionality to get the thumbnail and information on the file.
LP360 creates an LIDAR data layer in ArcMAP. “We created a custom LIDAR layer, the LAS layers, but we also added a tab to the table of contents. When you add multiple LAS files, because they’re often broken up into many tiny tiles, you can just select on and off the LIDAR, but you’re really toggling 300-400 tiles,” Haskell explained.
- GIS Fusion will work in the profile viewer as well as the 3D viewer but really the best functionality is in the 3D viewer. This allows you to take that TIN or the point cloud that you’re looking at in 3D and merge your GIS project to it. You can send up your GIS project with different transparencies and multiple layers point files, objects, icons, etc. You can set up in your project and can fuse that to the point cloud or the TIN in the 3D window or to the profile. This enables you to see certain things such as, if you have a boundary of a watershed, with Fusion you can see exactly where that boundary overlays on the point cloud.
- Blending the imagery with other data layers – This capability is part of GIS Fusion for use in analysis and visualization.
In summary, Haskell said LP360 brings the point cloud to ArcGIS users. By not requiring users to take the LIDAR data to a proprietary format or to a grid, people can work with the point cloud, “which is untapped and we’re providing the first link to providing that full potential.”
