Title: Area between Peaks Feature in the Derivative Reflectance Curve as a Sensitive Indicator of Change in Chlorophyll Concentration
Eric Ariel L. Salas, Geoffrey M. Henebry
Abstract: Vegetation spectral features can detect chlorophyll concentrations. Two key spectral features evident in the first derivative (FD) of reflectance constitute the two main peaks: one located around 685-705 nm and the other near 710-725 nm. We propose that the area between peaks (ABP) can be used as a sensitive indicator of changes in the photosynthetic pigments at leaf level and demonstrate it using a high-spectral-resolution dataset of maize leaves collected by Gitelson and coworkers (2005). We find significant high positive correlations (r2 > 0.90) between chlorophyll concentrations and both the ABP and its continuum length feature. Read more here.

Surrey Satellite Technology US LLC (SST-US) today introduced the Surrey V1C color video-imaging satellite, a new compact design with high-quality imaging at sub-one-meter resolution. Priced at less than $20 million, the V1C design has significant space heritage and provides a 10-kilometer color video imaging swath.
The Surrey V1C satellite will collect high-definition, natural-color (red, green, blue) video with better than one-meter ground sample distance (GSD) resolution over a 10-kilometer-wide swath at up to 100 frames per second. In addition to video, the camera can operate in still scene imager mode. The Surrey V1C spacecraft is based on the new SSTL-X50 satellite bus derived from mission-proven Surrey spacecraft designs. The satellite has large onboard data storage capabilities for store and forward as well as real-time downlink technology.
SST-US announced plans for the Surrey V1C satellite in booth #2090 at the GEOINT 2013* Symposium being held this week in Tampa, Fla.
“The demand for high-quality, wide-swath video solutions from customers engaged in business analytics and U.S. geospatial intelligence missions has been a key driver behind the development of our current suite of affordable, high-value small imaging satellites. The V1C delivers next-generation video capability at a very low cost, helping close the video-derived products business case and serve intel mission profiles that require constellations for a robust end-user information products,” said Doug Gerull, SST-US’s chief operating officer.
SST-US has been developing a new complete suite of high-value, affordable small satellites for U.S. geospatial intelligence missions, Gerull explained. This suite includes the Surrey V1C and the Surrey L1 half-meter electro-optical imaging satellites announced at GEOINT. These mission-configurable spacecraft are applicable to a broad spectrum of intelligence collection requirements, such as surveillance, detection, and identification.
SST-US developed the Surrey V1C for organizations that need satellite data to be collected and analyzed quickly for situational awareness and activity-based intelligence (ABI) applications related to rapidly changing human or infrastructure conditions on the ground.
“The primary use of video imaging from space is to quickly understand activity on the ground and make informed decisions in short periods of time. The basic limitation of time-over-target for video can be overcome by a constellation of satellites made economically feasible by a low cost per spacecraft,” said Gerull.
Demonstrated architectures and cost-effective prices mean Surrey’s geospatial intelligence satellites are well suited to multi-satellite constellation configurations. Many on-orbit configurations are possible depending on the number of satellites launched—Surrey V1Cs can deploy in phased orbits trailing one another by 30 to 60 minutes, in order to provide nearly continuous video coverage during specific times of the day.
SST-US’s new manufacturing facilities in Englewood, Colorado, allow the build of V1C satellites in the U.S. and accelerate Surrey’s already proven fast build times. The Englewood facility is currently processing the Surrey Orbital Test Bed mission which will host high-value payloads from customers such as NASA JPL.
Leveraging Surrey’s 100 percent successful 41 satellite mission legacy, SST-US is also positioned to assist satellite customers with launch services and satellite command and control.

JGR-Biogeosciences focuses on biogeosciences of the Earth system in the past, present, and future and the extension of this research to planetary studies. The emerging field of biogeosciences spans the intellectual interface between biology and the geosciences and attempts to understand the functions of the Earth system across multiple spatial and temporal scales. Studies in biogeosciences may use multiple lines of evidence drawn from diverse fields to gain a holistic understanding of terrestrial, freshwater, and marine ecosystems and extreme environments. Specific topics within the scope of the section include process-based theoretical, experimental, and field studies of biogeochemistry, biogeophysics, atmosphere-, land-, and ocean-ecosystem interactions, biomineralization, life in extreme environments, astrobiology, microbial processes, geomicrobiology, and evolutionary geobiology.

The Missouri Spatial Data Information Service (MSDIS) is providing free LiDAR data products!
The Missouri Spatial Data Information Service (MSDIS) is the State of Missouri’s designated National Spatial Data Inventory (NSDI) clearinghouse node. In order to better serve Missouri’s geospatial data users, MSDIS is encouraging node partnerships with other interested distributers of geospatial data in the state. These associations will expand existing partnerships and encourage future collaborations with these partners. MSDIS is also looking to encourage other state academic institutions to partner to expand and leverage MSDIS’s relational network for further research, service and educational opportunities.
Through these efforts MSDIS hopes to build stronger affiliations and further relationships with many groups and entities wherein we can achieve more regionalized data inventory, integration, and warehousing for Missouri. This will also help to achieve further continuity of operations for the MSDIS.
In discussions dating to early 2008, Washington University in St. Louis, expressed an interest in working with MSDIS to further the geospatial goals of Missouri. MSDIS has identified an opportunity in the form of a significant increase in LiDAR (Light Detecting and Ranging) data being collected in the state. Almost 20% of the state has been collected – representing a total repository of approximately 1TB of data – with rapid growth in these acquisitions occurring in the near future.
LiDAR data products such as derived Digital Elevation Models are in increasing demand across Missouri. Washington University has performed a similar role in their support of NASA projects and associated terrain and image data warehousing. Washington University has the requisite personnel, expertise, data storage space, and server technologies to serve this data to the geospatial community. Under the auspices of MSDIS – and as its first State Clearinghouse Partnership Node, Washington University will act as a central repository for all of the State’s LiDAR raw and derived data products. They will serve the data as received – and provide associated links for inclusion within the MSDIS clearinghouse.
