Abstract
Evapotranspiration monitoring allows us to assess the environmental stress on forest and agricultural ecosystems. Nowadays, Remote Sensing and Geographical Information Systems (GIS) are the main techniques used for calculating evapotranspiration at 5 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 climate modelling to estimate daily evapotranspiration (ETd) for several dates between 2003 and 2005. The three main variables needed to compute ETd were obtained as follows: (i) Land surface temperature by means of the Landsat-5 TM and Landsat-7 10 ETM+ thermal band, (ii) air temperature by means of multiple regression analysis and spatial interpolation from meteorological ground stations data at satellite pass, and (iii) net radiation by means of the radiative balance.

Abstract: Problem statement: The areas of Faliraki and Delta Pinaeus river is presented with downgrade in natural resources that has a direct affect on the future development of these areas. The research investigated (i) whether land uses have downgraded the coastal areas (ii) to which degree the determination of land uses can play an important role in the reduction of environmental problems and in the protection of an area. Approach: An exploratory descriptive statistics and a comparative method were used on the employment in the productive sectors, built-up development and tourist development In addition to this, personal interviews took place with the people in charge of technical services of corresponding municipalities.

Ursachen für die Ausprägung Urbaner Wärmearchipele:

Vermehrte Absorption von kurzwelliger Strahlung durch vergrößerte Oberfläche und geometriebedingt verstärkte Reflexion

Verminderte langwellige Strahlungsverluste durch Horizontüberhöhungen

EarthScope

Many fundamental aspects of continental structure and dynamics, including those responsible for earthquakes and volcanic eruptions, are not yet well understood. This is, in part, because of the diffi culty of piecing together the results of many focused, regional studies carried out by a single investigator or a small team of investigators.

Aufgaben und Ziele
Kompetenznetzwerke gewinnen zunehmend an Bedeutung. Sie bündeln fachlich-regionale Ressourcen und erhöhen die Wettbewerbsfähigkeit am Markt. Im Kompetenznetzwerk für Geoinformatik agieren regionale Akteure aus Wissenschaft und Wirtschaft um hochwertige Innovationen und marktfähige Produkte für den Geoinformatinsmarkt in Niedersachsen hervorzubringen.

Agricultural Aircraft

Sometimes the solution to a problem is in one’s own backyard. For agricultural engineer Steven J. Thomson, readily available agricultural airplanes provided a solution to the need for high-resolution images as part of remote sensing techniques for the Mississippi Delta.
