Application of Remote Sensing in AgricultureUTTAM KUMAR
Remote sensing has been found to be a valuable tool in evaluation, monitoring and management of land, water and crop resources. The launching of the Indian remote sensing satellite (IRS) has enhanced the capabilities for better utilization of this technology and significant progress has been made in soil and land cover mapping, land degradation studies, monitoring of waste land, assessment of crop conditions crop acreage and production estimates
In India, agriculture is one of the major application areas of the remote sensing technology. Various national level agricultural applications have been developed which showcases the use of remote sensing data provided by the sensors/satellites launched by the country’s space agency, Indian Space Research Organisation (ISRO)
Precision agriculture is an art and science of utilizing innovative, site-specific techniques for management of spatial and temporal variability using affordable technologies… for enhancing output, efficiency, and profitability of agricultural production in an environmentally responsible manner
Applications of GIS in Public Health EngineeringVignesh Sekar
GIS is used to support decision making for planning and management of land use, natural resources, environment, transportation, urban facilities, and other administrative records. Remote sensing and GIS makes easier to get valuable information about the study area. GIS enables us to integrate different layers and to manage large database. It gives more accurate results when compared to conventional methods. Hence GIS is proved to be a powerful tool in managing spatial and non spatial databases in suitability evaluation.

Remote sensing and geographic information systems (GIS) analysis involves the use of technology to gather, manipulate, and analyze spatial data to understand a range of phenomena. Remote sensing entails obtaining information about the Earth's surface by examining data acquired by a device, which is at a distance from the surface, most often satellites orbiting the earth and airplanes. GIS are computer-based systems that are used to capture, store, analyze, and display geographic information. These two approaches are used widely, often together, to assess natural resources and monitor environmental changes. Social scientists can gain insights into fine spatial and temporal dynamics of a range of social phenomena in environmental contexts by analyzing time series of remote sensing data, by linking remote sensing to socioeconomic data using GIS, and developing with these data a range of digital models and analyses. This article examines remote sensing and GIS in general, with an emphasis on the former, and then explores how these approaches may be used together to address a range of issues. It also emphasizes the role of remote sensing and GIS for use by scientists, engineers & geologists in water resources management
Remote sensing and GIS are two interrelated fields of geoinformatics that deal with the collection, analysis, and display of data about the earth's surface. Remote sensing is the science and technique of measuring and recording the properties of objects or phenomena without physical contact, using electromagnetic radiation (EMR) data from aircraft and satellites ¹. GIS is a computer-based tool for mapping and analyzing the spatial and statistical aspects of the data, using databases and visual representations ¹.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

3. Definition:
• A GIS is a computer based tool for mapping ,analyzing
things that exist and events that happen on earth.
(OR)
• A database system in which most of the data are
spatially indexed, and upon a set of procedures
operated in order to answer queries about spatial
entities in the database.
Smith et al,1987
Burrough,1986
4. Components of GIS:
A working GIS integrates five key components:
Hardware
Software
Data
People
Methods
General purpose GISs essentially perform five processes or tasks:
Input Manipulation Management Query and Analysis

Let’s take this tree for example...
This tree has a location - described with a latitude and longitude - it is located at 51oN and 112oW. This is its "location information".
This same tree also has additional “attribute information”. This is an oak tree, it is 15m high and it is 75 years old.
