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.

The latest index of airborne geophysical surveys from across Australia has been released. This edition includes details of all available open-file surveys completed to date by the Australian, State and Territory governments, as well as the private sector.
This type of data is used to generate three dimensional models of the sub-surface geology, which can then be used to support decision making related to the development of resources, management of the environment and the wellbeing of communities in the survey areas.
The Index of Airborne Geophysical Surveys (14th Edition) now includes details on surveys that have acquired more than 34.9 million line kilometres of mainly magnetic intensity and gamma-ray spectrometric data. It also includes details on surveys where land elevation data are derived from GPS recordings made during airborne magnetic and gamma-ray spectrometric surveys, with electromagnetic data also available for some areas.
Geophysical survey data measures variations in the Earth's physical properties caused by changes in the physical properties of rocks in the sub-surface, such as magnetisation, natural radioactivity and electrical conductivity.
Since 1999, Geoscience Australia and State and Territory Geological Surveys have contracted airborne geophysical companies to undertake surveys, either separately or as part of joint projects. Geoscience Australia's predecessors the Australian Geological Survey Organisation (AGSO) and the Bureau of Mineral Resources (BMR) used their own aircraft between 1951 and 1999. Airborne survey index information was first published in 1977 by the BMR.
The open-file airborne geophysical data included in the National Airborne Geophysical Database are available free via the Geophysical Archive Data Delivery System on the Australian Government Geoscience Portal. This includes all open-file geophysical surveys completed prior to this latest edition.

The Athens Institute for Education and Research (ATINER) was established in 1995 as an independent world association of Academics and Researchers. Its mission is to act as a forum where Academics and Researchers from all over the world can meet in Athens, in order to exchange ideas on their research, and to discuss future developments in their disciplines.
The organizing and hosting of International Conferences and Symposiums, the carrying out of Research, and the production of Publications are the basic activities of ATINER. Since 1995, ATINER has organized more than 350 International Conferences and other events, and has published close to 150 books. In 2012, the Association launched a series of conference paper publications (click here), and at the beginning of 2014, it introduced its own series of Journals.
Academically, the Association is organized into six Research Divisions and thirty Research Units. Each Research Unit organizes at least an Annual International Conference, and may also undertake various small and large research projects.
Academics and Researchers are more than welcome to become members and to contribute to ATINER's objectives. If you would like to become a member, please download the relevant form (membership form).

We are pleased to report an increased Impact Factor for Remote Sensing for 2013. According to the newly released 2013 Journal Citation Reports Science Edition (Thomson Reuters, 2014), the new Impact Factor for Remote Sensing is 2.623. The 5-Year Impact Factor is 2.729. Remote Sensing now ranks 6/27 (Q1) in the category ‘Remote Sensing’.
Evolution of the Remote Sensing Impact Factor since 2012:
Postdoctoral Position Available: Geospatial change analysis of the western hemisphere
We are seeking a highly motivated and capable PDF to pursue cutting-edge interdisciplinary research in the field of geospatial sciences within the context of the newly funded NASA project:
Change in our MIDST: Detection and Analysis of Land Surface Dynamics in North and South America Using Multiple Sensor Datastreams.
We propose to answer the cross-cutting question: “Where in the western hemisphere is the vegetated land surface changing significantly during the past 15 years in response to direct human impacts? We formulate our question as a suite of testable hypotheses about changes in the vegetated land surface, as follows:
[H1] Areas of significant positive change occur in areas of moderate human impact, due predominantly to agricultural land uses;
[H2] Areas of significant negative change that occur in areas with low human impact, arise predominantly from forest pests and forest fires; and
[H3] Areas of significant negative changes that occur in areas with high human impact, appear predominantly associated with the expansion of human settlements, particularly cities.
We will build and implement a system to detect significant changes in land surface properties using time series of key NASA remote sensing data products from sensors aboard Terra and/or Aqua, supplemented by products from NASA's Global Land Data Assimilation System and the Tropical Rainfall Measuring Mission. We will calculate trends since 2001 for metrics of the vegetated land surface using multiple sensor datastreams. An important aspect of the system is trend analysis on two or more scales, e.g., 500m and 0.05 degree. We will highlight areas manifesting highly significant changes in land surface properties in North, Central, and South Americas to assess changes since 2001, with particular interest focused on  the rapidly transforming cerrado region of Brazil and  the hemisphere’s largest conurbations. We will analyze for the drivers and consequences of change through a combination of regularized generalized canonical correlation analysis, recursive partitioning, and probabilistic mixture modeling of land surface phenologies.
Applicants should have earned Ph.D. in ecology, geography, environmental science, or a closely related discipline along with a strong conceptual background in landscape ecology, land change science, ecological remote sensing, or other appropriate field. A background in statistical analysis, geographic information systems, experience with remote sensing, computer programming skills (C, C++, Java, etc.) and knowledge of ENVI/IDL and the R environment are all highly desirable.
