The use of new technologies of learning can be applied to the classroom. Computer learning supports meaningful and long-term learning. Therefore, in the era of digital society and environmental issues, a relevant role is provided by open source software and free data that promote universality of knowledge. Earth observation (EO) data and remote sensing technologies are increasingly used to address the sustainable development goals. An important step for a full exploitation of this technology is to guarantee open software supporting a more universal use. The development of image processing plugins, which are able to be incorporated in Geographical Information System (GIS) software, is one of the strategies used on that front. The necessity of an intuitive and simple application, which allows the students to learn remote sensing, leads us to develop a GIS open source tool, which is integrated in an open source GIS software (QGIS), in order to automatically process and classify remote sensing images from a set of satellite input data. -

Bellaterra, July 2013 Dr. Francesc Aulí Llinàs and Dr. Joan Serra Sagristà (Supervisors) Committee: Dr. Michael W. Marcellin Dr. Ian Blanes García Dr. Víctor Francisco Sánchez Silva Dr. David Megías Jiménez (substitute) Dr. Ferran Marqués Acosta (substitute) To Emma and María ii Abstract Nowadays, with the advent of information technology and communications, images are widely used in many areas of our life. When sharing or transmitting images, the network bandwidth is a major concern, especially for large resolution images. In a client-server scenario, the bandwidth consump- tion increases along with the number of images requested by a user and with the number of users. Thus, ecient transmission strategies are needed to reduce the transmission cost and the client's response time. Eciency can be achieved through compression and by using a suitable transmis- sion protocol. JPEG2000 is a state-of-the-art image compression standard that excels for its coding performance, advanced features, and for its powerful interactive transmission capabilities. -
1 Geographical Information Systems (GIS)
Geographical Information Systems (GIS) Introduction Geographical Information System (GIS) is a technology that provides the means to collect and use geographic data to assist in the development of Agriculture. A digital map is generally of much greater value than the same map printed on a paper as the digital version can be combined with other sources of data for analyzing information with a graphical presentation. The GIS software makes it possible to synthesize large amounts of different data, combining different layers of information to manage and retrieve the data in a more useful manner. GIS provides a powerful means for agricultural scientists to better service to the farmers and farming community in answering their query and helping in a better decision making to implement planning activities for the development of agriculture. Overview of GIS A Geographical Information System (GIS) is a system for capturing, storing, analyzing and managing data and associated attributes, which are spatially referenced to the Earth. The geographical information system is also called as a geographic information system or geospatial information system. It is an information system capable of integrating, storing, editing, analyzing, sharing, and displaying geographically referenced information. In a more generic sense, GIS is a software tool that allows users to create interactive queries, analyze the spatial information, edit data, maps, and present the results of all these operations. GIS technology is becoming essential tool to combine various maps and remote sensing information to generate various models, which are used in real time environment. Geographical information system is the science utilizing the geographic concepts, applications and systems. -

Remote Sensing and Gis (A70140)
LECTURE NOTES ON REMOTE SENSING AND GIS (A70140) IV B. Tech I Semester (JNTUH-R15) By Mr. Y. Ravi Kumar Assistant Professor DEPARTMENT OF CIVIL ENGINEERING INSTITUTE OF AERONAUTICAL ENGINEERING (Autonomous) DUNDIGAL, HYDERABAD - 500 043 1 UNIT-1 PHOTOGRAMMETRY Photogrammetry is the science of making measurements from photographs, especially for recovering the exact positions of surface points. Moreover, it may be used to recover the motion pathways of designated reference points located on any moving object, on its components and in the immediately adjacent environment. Photogrammetry may employ high-speed imaging and remote sensing in order to detect, measure and record complex 2-D and 3-D motion fields (see also sonar, radar, lidar etc.). Photogrammetry feeds the measurements from remote sensing and the results of imagery analysis into computational models in an attempt to successively estimate, with increasing accuracy, the actual, 3-D relative motions within the researched field. Low altitude aerial photograph for use in Photogrammetry - Location Three Arch Bay, Laguna Beach CA. Its applications include satellite tracking of the relative positioning alterations in all Earth environments (e.g. tectonic motions etc.), the research on the swimming of fish, of bird or insect flight, other relative motion processes ( International Society for Photogrammetry and Remote Sensing). The quantitative results of photogrammetry are then used to guide and match the results of computational models of the natural systems, thus helping to invalidate or confirm new theories, to design novel vehicles or new methods for predicting or/and controlling the consequences of earthquakes, tsunamis, any other weather types, or used to understand the flow of fluids next to solid structures and many other processes. -
Automatic Metadata Extraction from Geographic Information
Automatic Metadata Extraction from Geographic Information M.A. Manso1, J.Nogueras-Iso2, M.A. Bernabé1, F.J.Zarazaga-Soria2 1 Department of Topography and Cartographic Engineering Polytechnic University of Madrid Campus Sur, Carretera de Valencia, km 7. 28031- Madrid (Spain) [email protected], [email protected] 2 Department of Computer Science and Systems Engineering University of Zaragoza María de Luna 1, 50018 Zaragoza (Spain) [email protected], [email protected] ABSTRACT One of the biggest problems for implementation of a Spatial Data Infrastructure is the creation of metadata because it requires a high knowledge of sciences related to cartography and a good infrastructure of tools that allow to get information from the original Geographical Information and which carry out transformations or conversions of coordinates, transcription of multiple information, etc.. This fact has motivated a detailed study of file formats of geographical information. The objective was to identify the information which can be acquired from its own files and to study how they are related with the metadata standard of geographical information. The study has shown different techniques used by enterprises to store meta information in form of headers, directories and labels. Homogeneous groups of information which can be retrieved from the different categories of formats have been identified. This study has provided a high range of conclusions and perspectives which should be guidelines for future work. KEYWORDS: Geographic Metadata, file formats for geographic information, extraction of metadata INTRODUCTION Metadata are "data about data", that is to say, they describe the content, quality, condition, and other characteristics of data in order to help a person to locate and understand data.
