Several papers on plant protection were presented at last conference of Society for Range Management in US (WA). Lohani et al. presented the use of state maps of the vegetation which was used to assess the effectiveness of brush management practices to drive vegetation communities on several ecological sites from one state to another. To assess the effectiveness of management practices the study used high-resolution satellite imagery and ground-based data to map vegetation states within identified ecological sites on the Empire Ranch, located within the Las Cienegas National Conservation Area (LCNCA) in southeastern Arizona.
The combination of remotely-sensed images, field monitoring, and state and transition models shows great potential as a means of mapping states and evaluating the benefits of established management practices to drive transitions from one vegetation state to another across large areas.

Earth Resources and Environmental Remote Sensing/GIS Applications conference will take place in Edinburg (UK), 24-27 Sept. 2012. The organizers have launched an open call for papers.
Satellite remote sensing has become a common tool to investigate the different fields of Earth and environmental sciences. The progress of the performance capabilities of the optoelectronic and radar devices mounted on-board remote sensing platforms have further improved the capability of instruments to acquire information about the Earth and its resources for global, regional and local assessments.
The conference will be an occasion to outline how scientists involved in the Earth and environmental studies can take advantage of new remote sensing techniques and the advances in spatial technology.
Remote-sensing technology provides a powerful means for land use/land cover (LU/LC) monitoring at global and regional scales. However, it is more efficient and effective to combine remote-sensing measurements with a geographic information system (GIS) database and expert knowledge for change updating than to use remote-sensing technology alone.

Welcome to the Remote sensing topic with plant canopy applications.
What is this about? Remote Sensing can be defined as obtaining information about an object by observing it from a distance and without coming into actual contact with it. Examples: Eye sight or Photos taken from a camera.
This topic will use the word remote sensing for data collection from artificial satellites orbiting the earth and processing such data to make useful decisions. Diseased plants or invasive species could be remotely detected.

The devastating series of fire events that occurred during the summers of 2007 and 2009 in Greece made evident the need for an operational mechanism to map burned areas in an accurate and timely fashion to be developed. In this work, Système pour l’Observation de la Terre (SPOT)-4 HRVIR images are introduced in an object-based classification environment in order to develop a classification procedure for burned area mapping.

Prof. Alan Strahler's current work involves a ground-based LiDAR instrument called ECHIDNA, after the spiky Australian egg-laying mammal.
Professor Strahler started off creating maps based on Landsat data before moving on to work with NASA's Terra and Aqua environmental satellites. Because these satellites carry identical MODIS (Moderate Resolution Imaging Spectroradiometer) instruments and have highly coordinated orbits, they can provide cloud-free data about the whole Earth on a day-to-day basis.
Bradley T. Lepper, who is curator of archaeology at the Ohio Historical Society, has recently posted news:
"In the October issue of the journal American Antiquity, two Ohio archaeologists — Jarrod Burks, with Ohio Valley Archaeology Inc., and Robert Cook, from Ohio State University — presented the results of their rediscovery of some of Ohio's lost earthworks using revolutionary remote-sensing technology.
Geophysical remote sensing encompasses a variety of methods for “seeing” beneath the ground. One of the main instruments used by Burks and Cook is the fluxgate magnetometer, which measures tiny variations in the magnetic properties of soil."
To enhance the success of prevention and management actions, we recommend (a) advancing technologies for molecular identification, expert systems, and remote sensing; (b) evolving approaches for ecosystem and landscape management; and (c) better anticipating interactions between species invasions and other global change processes.

GIS and Science:
"Remote Sensing and Geographical Information Systems (GIS) are the main techniques used for calculating evapotranspiration at catchment and regional scales. In this study we present a methodology, based on the energy balance equation (B-method), that combines remote sensing imagery with GIS-based climate modelling to estimate daily evapotranspiration (ET(d))..."
