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.
URISA is now accepting presentation proposals for its Seventh Caribbean GIS Conference, taking place October 27-30, 2014 in Curacao. Submissions are due by May 5, 2014.
Since 2001, URISA has presented successful conferences focused on the effective application and management of GIS and other information technologies within the Caribbean. Previous conferences have taken place in Jamaica (2001), Barbados (2004), the Bahamas (2006), Cayman Islands (2008), Trinidad and Tobago (2010) and Jamaica (2012). We are pleased to host the 2014 conference in the Dutch Caribbean!
Objectives of URISA's 2014 Caribbean GIS Conference:
To inform broad cross-section of Caribbean users about GIS technology and applications
To share experiences regarding GIS implementation and management issues
To establish new relationships with the vendor/consultant community
To provide workshops and sessions that are application driven, and are relevant to the Caribbean community of GIS users
To foster a Caribbean GIS network
To assess the state of readiness of national and regional Spatial Data Infrastructures
To act on directives from the High Level Meetings held over the past several years, fostering executive support for GIS
The conference program is developed through a Call for Presentations. The committee welcomes the submission of individual papers, complete sessions, panel discussions and lightning talks and has proposed a long list of suggested topics for consideration, from "Big data to support planning and development" to "Environmental monitoring and analysis".Interested individuals are encouraged to review the suggested topics list and consider submitting an abstract. Note that all abstracts received will be reviewed and considered for the conference program regardless of the list put forward.
Visit http://www.urisa.org/education-events/caribbean-gis-conference/ for further details and an online submission form. Submissions must be received by May 5, 2014.
This year, National Atlas of the United States and The National Map will transition into a combined single source for geospatial and cartographic information. This transformation is projected to streamline access to maps, data and information from the USGS National Geospatial Program ( NGP). This action will prioritize our civilian mapping role and consolidate core investments while maintaining top-quality customer service.
The USGS will continue its long history of providing topographic maps, geospatial data and other geographic information by offering a range of scales and layers of geospatial information on The National Map Viewer and through US Topo maps. As a result of the conversion to an integrated single source for geospatial and cartographic information, nationalatlas.gov will be removed from service on September 30, 2014.
"We recognize how important it is for citizens to have access to the cartographic and geographic information of our nation. We are committed to providing that access through nationalmap.gov", said Mark DeMulder, NGP Director.
"We value the National Atlas customers and stakeholders and want to make this transition as easy as possible," explained Jay Donnelly, the National Atlas Program Manager. "We will post updates to The National Map and National Atlas Websites as this transition unfolds, including information on the future availability of the products and services currently delivered by nationalatlas.gov."

National Geographic has been producing thematic maps for decades, revealing not just physical features but also location-based details on cultures, history, wildlife, science, and more. Now, a treasure trove of more than 500 of those maps are available online in a new service from Google Maps.
The National Geographic maps can be found in their own section of Google Maps Gallery, which launched officially on February 27. This includes reference maps, wall maps, National Geographic magazine supplement maps, and other creations from over the years, all laid on top of the relevant Google basemaps.
See the National Geographic gallery here.
Examples include a detailed map of Civil War battles, a classic Africa wall map, a map of adventure activities in the Dominican Republic, and a map that shows comparative information about the two Koreas.
"It's pretty epic to have all this stuff up online," says Frank Biasi, director of digital development for National Geographic Maps in Evergreen, Colorado.
Biasi says the new tool takes advantage of the Google Maps Engine on the backend.
"That's for organizations to publish maps for their own websites primarily, but Google Maps also has a public data program and they have invited certain publishers, including the Library of Congress, the World Bank, and National Geographic, to share maps publically through Google's Map Gallery," says Biasi.
"It's part of Google's mission to organize the world's information and make it universally accessible and useful."
The new maps galleries are being integrated into Google search results. Biasi says, "If someone does a search on 'India map' or something like that, any of our maps that have those words are going to come up and be highly ranked."
Biasi says he hopes the maps will be useful in educational settings and for "anyone who is curious about the world and how it used to be." He pointed to a thematic map of medieval England that was made in 1979 as a favorite.
"These maps contain a lot of carefully researched knowledge in addition to cartography and geographic features," says Biasi. "They can show how boundaries change, the distribution of people and languages, and many environmental issues."
Biasi adds that the maps can be embedded into other web pages or apps, and that Google may add an e-commerce element so that people can pay to download high-resolution versions of the maps. Each map already has a link to buy a print version.
"National Geographic members have always loved our maps, whether folded in our monthly magazine or purchased in stores or online," says Biasi. "The Maps Gallery puts our map collection at their fingertips."

Geomatics, a world leading developer of remote sensing and photogrammetric software and systems, announced today it supports data analysis of images from SkySat-1, the first in a planned constellation of 24 satellites from Skybox Imaging. Support for SkySat-1 is currently available in the company’s new software, Geomatica 2013 (Service Pack 3 – SP3).
SkySat-1 is a high-performance satellite capable of providing 4-band, high-resolution sub-meter class imagery. Operating in a sun-synchronous orbit of 600 km, SkySat-1 also provides the first commercial high-resolution, full-motion video from space at 30 frames per second.
“We are thrilled to be partnering with PCI Geomatics to ensure that our imagery products are seamlessly incorporated into user’s workflows,” said Matt Wood, Skybox Senior Director of Enterprise Solutions. “It is important that our imagery is easily accessible and can be used to derive information in a timely, operational manner. We’ve worked closely with PCI Geomatics to ensure speedy correction is possible in a way that is both highly accurate and automated.”
“Our customers have come to expect Geomatica to support new sensors as imagery becomes available, and Skybox is no exception,” said Terry Moloney, President and CEO of PCI Geomatics. “SkySat-1 and other future sensors that will make up Skybox’s constellation will open new and exciting possibilities for the operational use of imagery. We are pleased to be able to offer support very early on in this exciting new era of commercial earth observation where pervasive coverage and imaging is becoming increasingly possible.”
