it is highly useful for geography students in the field of remote sensing and it is in very simple and explanatory for the purpose of simplification with relevant images in this ppt.
This document help you to prepare Triangulation Network (TIN), Hillshade Map, Slope map, interpolation and Digital Elevation Model (DEM) in a area and how to interpret them.
With increasing use of remote sensing, the need for crispier, accurate and enhanced precision has deemed to the improvement in the spectral and spatial resolution of remotely sensed imagery. For most of the systems, panchromatic images typically have higher resolution, while multispectral images offer information in several spectral channels. Resolution merge (also called pan-sharpening) allows us to combine advantages of both kinds of images by merging them into one.
The resolution merge or pan sharpening is the technique used to obtain high resolution multi-spectral images. The color information is collected from the coarse resolution satellite data and the intensity from the high resolution satellite data.
The main constraint is to preserve the spectral information for aspects like land use. Saving theimage from distortion of the spectral characteristics is important in the merged dataset.
The most common techniques for spatial enhancement of low-resolution imagery combining high and low resolution data can be used are: Intensity-Hue-Saturation, Principal Component, Multiplicative and Brovey Transform.

A geographic information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present all types of geographical data. The acronym GIS is sometimes used for geographical information science or geospatial information studies to refer to the academic discipline or career of working with geographic information systems and is a large domain within the broader academic discipline of Geoinformatics. In the simplest terms, GIS is the merging of cartography, statistical analysis, and computer science technology.
This presentation is about the raster and vector data in GIS which is important and costly as well, through the presentation we will learn about both type of data.
IMAGE INTERPRETATION
Act of examining images to identify objects and judge their significance.
Information extraction process from the images.
An interpreter is a specialist trained in study of photography or imagery, in addition to his own discipline.
Aerial photographs and remote Sensing images employ electro magnetic energy as the mean of detecting and measuring target characteristics.
Involves a considerable amount of subjective judgment.
Highly dependent on capability of mind to generalize.
Takes place at different levels of complexity.

Climate Change All over the World .pptxsairaanwer024
Climate change refers to significant and lasting changes in the average weather patterns over periods ranging from decades to millions of years. It encompasses both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. While climate change is a natural phenomenon, human activities, particularly since the Industrial Revolution, have accelerated its pace and intensity

ENVIRONMENT~ Renewable Energy Sources and their future prospects.tiwarimanvi3129
This presentation is for us to know that how our Environment need Attention for protection of our natural resources which are depleted day by day that's why we need to take time and shift our attention to renewable energy sources instead of non-renewable sources which are better and Eco-friendly for our environment. these renewable energy sources are so helpful for our planet and for every living organism which depends on environment.
Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

“GIS is a computer system capable of
assembling, storing, manipulating, and
displaying geographically referenced
information, i.e. data identified according to their
locations.”
“A GIS is an organized collection of computer
hardware, software, geographic data, and
personnel to efficiently capture, store, update,
manipulate, analyze, and display all forms of
geographically referenced information.”
What Is GIS?
4. 4
Data Capture
Data sources are mainly obtained from manual digitization and
scanning of aerial photographs, paper maps, and existing digital
data sets.
Database Management and Update
data security, data integrity, and data storage and retrieval, and
data maintenance abilities
Geographic Analysis
The collected information is analyzed and interpreted
qualitatively and quantitatively.
Preparing Result
One of the most exciting aspects of GIS technology is the
variety of different ways in which the information can be
presented.
Principle
5. 5
Data Capture
The input of data into a GIS can be achieved through many different
methods of gathering. For example, aerial photography, scanning,
digitizing, GPS or global positioning system is just a few of the ways a
GIS user could obtain data.
Data Storage
Some data is stored such as a map in a drawer, while others, such as
digital data, can be as a hardcopy, stored on CD or on your hard drive.
Data Manipulation
The digital geographical data can be edited, this allows for many
attribute to be added, edited, or deleted to the specification of the
project.
Query And Analysis
GIS was used widely in decision making process for the new
commission districts. We use population data to help establish an equal
representation of population to area for each district.
Visualization
This represents the ability to display your data, your maps, and
information.
Functions
6. 6
Hardware
Computer System, Scanner, Printer, Plotter, Flat Board
Software
GIS software in use are MapInfo, ARC/Info, AutoCAD Map, etc. The
software available can be said to be application specific.
Data
A GIS will integrate spatial data with other data resources and can even use
a DBMS, used by most organization to maintain their data, to manage
spatial data.
Geographic data and related tabular data can be collected in-house or
purchased from a commercial data provider.
People
GIS users range from technical specialists who design and maintain.
Method
The map creation can either be automated raster to vector creator or it can
be manually victories using the scanned images.
Components

15. 15
GIS allows us to view, understand, and visualize data in many ways
that reveal relationships, patterns, and trends in the form of maps,
globes, reports, and charts.
A GIS helps you answer questions and solve problems by looking at
your data in a way that is quickly understood and easily shared.
GIS give the accurate Data.
Better Predictions and Analysis.
