Neon Provides Airborne LiDAR Data Sample Free

Posted on

The NEON Airborne Observation Platform (AOP) is an aircraft platform carrying remote sensing instrumentation designed to achieve sub-meter to meter scale ground resolution, bridging scales from organisms and individual stands of vegetation to satellite-based remote sensing.

Since 2013, AOP has conducted a series of engineering flight campaigns at select NEON domains for the purpose of 1) testing the nominal data collection parameters for these sites; and 2) evaluating data processing techniques and obtain prototype datasets that support spatial/temporal scaling studies by the research community. The remote sensing data collected during these campaigns have been processed and several first level engineering data products are available for distribution. Since these data were collected as part of Engineering Flight Campaigns, they are considered “engineering quality” and may not have sufficient QA/QC to meet all users’ needs.

Airborne Data Types

Each AOP payload consists of a visible to shortwave infrared imaging spectrometer, a scanning small-footprint waveform LiDAR for three-dimensional canopy structure measurements, and a high resolution airborne digital camera for fine-scale land use and cover identification. AOP flight campaigns are designed to collect quantitative information on land use change and changes to ecological structure and chemistry, including the presence and effects of invasive species across landscapes 100-300km2 surrounding NEON sites.



DLR/NASA – 3D radar measurements of forest areas

Posted on

The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is developing radar technology that, for the first time, will enable a three-dimensional visual representation of forest areas from the roots to the crowns. The radar experts at DLR partnered with the US aerospace agency NASA in a measurement campaign, which has now confirmed the capability of the F-SAR system. The cooperation was aimed at validating the suitability of the radar data to infer a variety of parameters, including a forest’s height or vertical structure. A tangle of treetops and branches, through which just the occasional clear area provides glimpses of the trunks and roots growing below. Whether it is woodland with German spruces or a tropical rainforest, very few sensors are able to see through this green carpet and clearly visualise the underlying structures.

“The collaboration with NASA allowed us to really test both the sensor technology and the algorithms. We could not have hoped for better results,” said Andreas Reigber, project coordinator at the DLR Microwaves and Radar Institute.

The DLR Microwaves and Radar Institute is currently preparing for Biomass, a European Space Agency (ESA) satellite-based mission that will conduct radar observations of Earth’s surface. The main focus of the mission is to determine the volume of biomass in the tropical rain forests. In addition, the Institute is at the forefront ofTandem-L, a highly innovative satellite mission tasked with using radar to record the dynamic processes unfolding on Earth’s surface. Together, these projects promise a level of scientific insight one would not necessarily expect from flying over an area of woodland.

Telangana Proposes Topographical Survey of Godavari River

Posted on

Determined to utilise the allocated Godavari waters fully, the state government has decided to carry out a topographical survey of the length and breadth of the stretch of river passing through the state.

The topographical survey of Godavari will be taken up right from Sripada Yellampally project site to Dummugudem project site. The irrigation department has proposed to get the stretch of Godavari in the state surveyed for several uses like development of water resources and for scientific studies.

“We want to utilise Godavari waters fully. The survey is intended to identify where check dams could be constructed and how the water could be diverted,” engineer-in-chief C Muralidhar told Express.

The topographical studies will be carried out by using geospatial survey technology. The state government has also decided to utilise Lidar technology to conduct a study on the Pranahita-Chevella project. Lidar technology will be limited to the proposed Medigadda barrage near Kaleswaram, whereas the topographical survey will be carried out on the entire stretch of Godavari in the state, officials said.

The barrage alignment at Medigadda, the alignment of proposed canal from Medigadda to Yellampalli will be decided through the latest Lidar technology.

Trimble, Now A LASzip Sponsor

Posted on

Trimble’s Geospatial Division has become a sponsor of the LASzip compressor. Their contribution as a Bronze sponsor will improve the existing “LAS 1.4 compatibility mode” of LASzip whose creation and maintenance is already being supported by Gold sponsor NOAA and Bronze sponsor Quantum Spatial. The original Gold sponsor of the open source LASzip compressor was USACE – the US Army Corps of Engineers (see

The “LAS 1.4 compatibility mode” was created to provide immediate support for compressing the new LAS 1.4 point types by rewriting them as old point types and storing their new fields as “Extra Bytes”. As an added benefit this allows older software (without LAS 1.4 support) to access the newpoint types of LAS 1.4 files that would otherwise be unreadable. All important fields of the new point types 6 to 10 (i.e. those fields that matter to older software) are mapped to the corresponding fields of the older known point types 1, 3, or 5.
