An overlay operation is much more than a simple merging of linework; all the attributes of the features taking part in the overlay are carried through. In general, there are two methods for performing overlay analysis—feature overlay (overlaying points, lines, or polygons) and raster overlay. Some types of overlay analysis lend themselves to one or the other of these methods. Overlay analysis to find locations meeting certain criteria is often best done using raster overlay (although you can do it with feature data). Of course, this also depends on whether your data is already stored as features or raster. It may be worthwhile to convert the data from one format to the other to perform the analysis.
Weighted Overlay
Overlays several raster files using a common measurement scale and weights each according to its importance.
The weighted overlay table allows the calculation of a multiple criteria analysis between several raster files.
Raster- The raster of the criteria being weighted.
Influence- The influence of the raster compared to the other criteria as a percentage of 100.
Field- The field of the criteria raster to use for weighting.
Remap- The scaled weights for the criterion.
In addition to numerical values for the scaled weights in Remap, the following options are available:
Restricted- Assigns the restricted value (the minimum value of the evaluation scale set, minus one) to cells in the output, regardless of whether other input raster files have a different scale value set for that cell.
No data - Assigns No Data to cells in the output, regardless of whether other input raster files have a different scale value set for that cell.

Image Index is a “synthetic image layer” created from the existing bands of a multispectral image. This new layer often provides unique and valuable information not found in any of the other individual bands.
Image index is a calculated result or generated product from satellite band/channels
It helps to identify different land cover from mathematical definition .
ENVIRONMENT
Definition: Environment literally means surrounding and everything that affect an organism
during its lifetime is collectively known as its environment.
In another words “Environment is sum total of water, air and land interrelationships
among themselves and also with the human being, other living organisms and property”.
It includes all the physical and biological surrounding and their interactions.
Environmental studies provide an approach towards understanding the environment of our
planet and the impact of human life upon the environment. Thus environment is actually
global in nature, it is a multidisciplinary subject including physics, geology, geography, history,
economics, physiology, biotechnology, remote sensing, geophysics, soil science and hydrology
etc.
Scope of Environmental Science
Environmental science is a multidisciplinary science whose basic aspects have a direct relevance
to every section of the society. Its main aspects are:
• Conservation of nature and natural resources.
• Conservation of biological diversity.
• Control of environmental pollution.
• Stabilization of human population and environment.
• Social issues in relation to development and environment.
• Development of non-polluting renewable energy system and providing new
dimension to nation’s security.Ecosystem
According to A.G. Tansley (1935), “An ecosystem is the ecological unit consisting of biotic factors
(living) and abiotic factors (non-living) in a specific area. For example forest, grassland, desert,
aquatic etc.
Balanced Ecosystem: All ecosystems, even the ultimate biosphere are open systems.
There is necessarily at least an inflow and outflow of energy. Balance of ecosystem means
balance of autotrophs and heterotrophs in an ecosystem, to maintain an even distribution of
sustainable energy through food chain without any external interference. Any disturbance in
autotrophic-heterotrophic balance leads to ecosystem imbalance, more the imbalance more
externals are required to balance. Bigger the ecosystems lesser is the imbalance. Balance infact
designates to greater primary producers than consumer.
Stability of Ecosystem: An ecosystem which has attained maturity is by and large is a
very stable system. It is controlled by feedback mechanic who may be either positive or
negative.
Structure and Function of an Ecosystem
An ecosystem has two types of components—
1. Abiotic
2. Biotic.
1. Abiotic component includes—
(A) Physical
(1) Sunlight (for photosynthesis)
(2) Water (essential for living beings)
(3) Temperature (necessary to get survive)
(4) Soil (provide base and nutrients)
(B) Chemical
(1) Proteins
(2) Carbohydrates
(3) Fats
(4) Minerals etc.
2. Biotic component
(1) Producers/Autotrophs
(2) Consumer/heterotrophs
(3) Decomposers
Producers: They are chlorophyll bearing, self nourishing organisms, which prepare
organic compounds from inorganic raw materials, through the processes of photosynthesis e.g.
all green plants.

Data Centers - Striving Within A Narrow Range - Research Report - MCG - May 2...pchutichetpong
M Capital Group (“MCG”) expects to see demand and the changing evolution of supply, facilitated through institutional investment rotation out of offices and into work from home (“WFH”), while the ever-expanding need for data storage as global internet usage expands, with experts predicting 5.3 billion users by 2023. These market factors will be underpinned by technological changes, such as progressing cloud services and edge sites, allowing the industry to see strong expected annual growth of 13% over the next 4 years.
Whilst competitive headwinds remain, represented through the recent second bankruptcy filing of Sungard, which blames “COVID-19 and other macroeconomic trends including delayed customer spending decisions, insourcing and reductions in IT spending, energy inflation and reduction in demand for certain services”, the industry has seen key adjustments, where MCG believes that engineering cost management and technological innovation will be paramount to success.
MCG reports that the more favorable market conditions expected over the next few years, helped by the winding down of pandemic restrictions and a hybrid working environment will be driving market momentum forward. The continuous injection of capital by alternative investment firms, as well as the growing infrastructural investment from cloud service providers and social media companies, whose revenues are expected to grow over 3.6x larger by value in 2026, will likely help propel center provision and innovation. These factors paint a promising picture for the industry players that offset rising input costs and adapt to new technologies.
According to M Capital Group: “Specifically, the long-term cost-saving opportunities available from the rise of remote managing will likely aid value growth for the industry. Through margin optimization and further availability of capital for reinvestment, strong players will maintain their competitive foothold, while weaker players exit the market to balance supply and demand.”

NNo WHAT IS LAND DEGRADATION : Land
degradation is a process in which the value of the
biophysical environment is affected by a combination of
human activities and natural processes acting upon the
land.
o BACKGROUND OF THE PROBLEM : Land
degradation has been identified as one of the key global
problems today that is at the root cause of poverty, food
insecurity and malnutrition. it is increasing in many
parts of the world.

6. STATEMENT OF THE PROBLEMSTATEMENT OF THE PROBLEM
We are discussing supercritical degraded
landscape in semi-arid area rural Kzn(Nsuze).
Community of Nsuze are faced with a critical
challenge of soil degradation which has a huge
impact in their lives. They cannot practice
agricultural farming because of the soil texture.

Objective 1
12. Data analysis
After we have done the samplings
and interviews we will
synthesize, interpret data to find
the exact problem and suitable
solutions.
13. ConclusionConclusion
• People who are poor and hungry often destroy their environment in order to survive
We have found soil erosion as the significant research
topic to study for particularly rural communities to be
aware of how to save their land in a way that will benefit
both the land those who are living in it.
They cut down forests
Their livestock overgraze grassland
They overuse land
They crowd into congested cities
Editor's Notes
This study will fruitfully enhance the knowledge of the community regarding soil erosion. It is aimed at enlightening people about soil degradation and ways to avoid and minimize impacts of soil degradation processes in rural dry land area of Nsuze
what is a non-parametric test? Why do interview government officials?
How many people will be interviewed? How are going to analyze this data?
