The document discusses remote sensing and its key elements. It begins with an introduction to remote sensing, defining it as obtaining information about an object without physical contact through analysis of data from devices. The principles of remote sensing are then outlined, including how electromagnetic energy interacts with and is reflected from Earth's surface features. The main components of a remote sensing system are identified as the energy source, propagation through the atmosphere, energy interaction with targets, sensor recording, transmission and processing, interpretation, and applications. Key advantages of remote sensing include large area coverage enabling regional surveys and monitoring of dynamic phenomena over time.
What is remote sensing?
Observing or measuring things from a distance
How is remote sensing useful?
It enables us to study nature in ways that would otherwise be beyond human capability, across great distances and at wavelengths of light invisible to human eyes.
How is remote sensing done?
By employing special detectors to record light as it’s emitted or
reflected by the objects of interest to us; and
By studying and manipulating the recorded images we get, so that we can answer our questions about nature.

This is all about remote sensing. Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to on-site observation, especially the Earth.Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance from the targeted area. Special cameras collect remotely sensed imagesof the Earth, which help researchers "sense" things about the Earth.

APPLICATION OF REMOTE SENSING AND GIS IN AGRICULTURELagnajeetRoy
India is a country that depends on agriculture. Today in this era of technological supremacy, agriculture is also using different new technologies like some robotic machinery to remote sensing and Geographical Information System (GIS) for the betterment of agriculture. It is easy to get the information about that area where human cannot check the condition everyday and help in gathering the data with the help of remote sensing. Whereas GIS helps in preparation of map that shows an accurate representation of data we get through remote sensing. From disease estimation to stress factor due to water, from ground water quality index to acreage estimation in various way agriculture is being profited by the application of remote sensing and GIS in agriculture. The applications of those software or techniques are very new to the agriculture domain still much more exploration is needed in this part. New software’s are developing in different parts of the world and remote sensing. Today farmers understand the beneficiaries of these kinds of techniques to the farm field which help in increasing productivity that will help future generation as technology is hype in traditional system of farming.

Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to in situ observation. In modern usage, the term generally refers to the use of aerial sensor technologies to detect and classify objects on Earth (both on the surface, and in the atmosphere and oceans) by means of propagated signals (e.g. electromagnetic radiation). It may be split into active remote sensing (when a signal is first emitted from aircraft or satellites)[1][2][3] or passive (e.g. sunlight) when information is merely recorded.
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.
Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

3. 1.1 Introduction to Remote sensing
Remote sensing is the science and art of obtaining information
about an object , area or phenomena, thought the analysis of data
acquired by a device
that is not in contact with the object, area or phenomena under
investigation.
Remote sensing is the acquiring of data about an object without
touching it.
Remote sensing is the non-contact recording of information from
the ultraviolet, visible, infrared and microwave regions of the
ectromagnetic spectrum by instrument such as camera , scanners,
lasers area located on platforms such as platforms on aircraft or
spacecraft.
4. Remote sensing is the acquiring of data about an object without
touching it.
Remote sensing includes aerial photography and satellite imagery.
This technology firs use in the united states in the 1960.
The first earth observation satellite was launched in 1972.
now remote sensing has become widely used.
Today most natural resource mapping is done using remote
sensing.
It is used topographical maps like forest map, geological map,
soil map, land map etc. with help of aerial survey.
5. 1.2 Principle to Remote sensing
Basic Principle to Remote sensing :
The sun and various artificial sources radiate electromagnetic
energy of variable wavelength.
All object on the surface of the earth have spectral signatures. A
spectral signature of an object or ground surface feature is a set of
value for the reflectance or radiance of the feature.
The electromagnetic energy interact with earth surface and various
feature like building, soil, grass, water, paved road, forest.
The response of ground surface material to incident radiation is the
reflectance and the energy emitted by all object as a function of
their temperature and structure is emittance.
The reflectance and emittance determine the signatures.
6. The knowledge of spectral signature is essential for exploiting the
potential of the remote sensing techniques. This knowledge
enables one to identify and classify objects.
When radiation is incident on a surface it is reflected, absorbed,
scattered and transmitted.
All the process are strongly dependent on the wavelength of the
incident radiation, as well as the atomic and molecular structure
of material.
7.
8. 1.3 Advantages of Remote sensing system
Main Advantages of Remote sensing system :
Satellite images are permanent records it providing useful
information in various wavelengths.
Large area coverage enables regional surveys on a variety of them
and identification of large features.
Respective coverage allows monitoring of dynamic them like water
agriculture etc.
Easy data identify at diff. scales and resolution.
A single remote sensor image can be analyses and interpreted for
diff. purpose and applications.
A remotely sensed data for fast processing using a computer.
It is using a natural source of energy.
9. The images are analysed in the laboratory thus reducing the
amount of field work.
Map revision at medium to small scales is economical and faster.
Floods over a large region or forest fire can be located from above
and rescue planning can be immediately arranged.
The data generated by remote sensing techniques can be used for
land use planning, forest development, geological surveys, urban
planning, disaster management etc.
10. 1.4 components of Remote sensing system
Main components of Remote sensing system :
Energy source
Propagation of energy through the atmosphere
Interaction of energy with target
Recording of energy by sensor
Transmission – reception and processing
Interpretation and analysis
application
11. 1.Energy source : the sun is the sources of energy is passive remote
sensing. The sun produces electromagnetic energy.
2. Propagation of energy through the atmosphere : the energy from
the sources propagates through the atmosphere. Modifies the
wavelength and spectral distribution of energy to some extent.
3. Interaction of energy with target : the energy received by the target
interact where it is either transmitted, absorbed, scattered, emitted or
reflected from the target
4. Recording of energy by sensor : the return signal is set to the
sensor which response to all wavelength. Sensor are mounted on
satellites.
12. 5. Transmission – reception and processing : the energy recorded by
the sensor has to be transmitted. Often in electronic from to a
receiving and processing station on the ground where the data are
processed into an images. the data products are mainly two types
1. Photographic product
2. Digital product.
6. Interpretation and analysis : the processed image are interpreted,
visually or digitally or electronically to extract information about the
target of interest
7. Application : the information about the target obtained from the
remote sensing is made available to the users in the desired from.
