Application of Geo-informatics in Environmental ManagementMahaMadhu2
Geo-informatics is the science and the technology which develops and uses information science, infrastructure to address the problems of geography, geosciences and related branches of engineering. “The art, science or technology dealing with the acquisition, storage, processing, production, presentation & dissemination of geo-information“. Perhaps the most important concern for all of us today is protecting the environment we live and breathe in. Climate change issues are creating havoc with erratic weather patterns affecting everything from crop production to untimely melting of ice glaciers.
There is a lot to worry about and immediate action is definitely required. It’s not that the world has not geared up to take corrective actions, but we need to do more, and Geo-informatics can help us achieve that. Geo-informatics is a powerful platform which enables every sector to perform better and the environment is no exception! Coupled with a digital map, GIS allows a user to see locations, events, features, and environmental changes with unprecedented clarity, showing layer upon layer of information such as environmental trends, soil stability, pesticide use, migration corridors, hazardous waste generators, dust source points, lake remediation efforts, and at-risk water wells. Effective environmental practice considers the whole spectrum of the environment. ArcGIS® & other GIS technologies offers a wide variety of analytical tools to meet the needs of many people, helping them make better decisions about the environment. People in the environmental management community use GIS to organize existing information and communicate that information throughout their organizations. GIS can be used as a strategic tool to automate processes, transform environmental management operations by garnering new knowledge, and support decisions that make a profound difference on our environment.

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 is presentation is intended for middle school students. It provides a short introduction to GIS and how to use GIS in the real-world.

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 is the acquiring of information from a distance and also the art and science of making measurements of the earth using airborne- or satellite-based sensors, is used in GIS. GIS is a collection of computer-based tools for organizing information from a variety of data sources to map and examine changes on Earth. Global Positioning System or GPS is a space-based radio navigation system that helps pinpoint a three-dimensional position to about a meter of accuracy (for example latitude, longitude and altitude) and provide nano-second precise time anywhere on Earth.

The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.
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.

2. DBMS
Data Base Management System (DBMS) is basically a program that is designed
to store and manage large amounts of data and provides controlled access to
the database to the users.
-Allow storage, retrieval and selection of data
-Standardize access to data
-Provide interface between database and application program based on logical
data description
-Allow several users to access the data simultaneously
-Protect the database from indiscriminate and illegal changes
-Provide sound rules for data consistency

GIS
Documentation of GIS systems,geospatial data
Red –very high flood risk
Yellow-high flood risk
Green-moderate flood risk
Brown-low flood risk
Maroon-very low flood risk
6. GIS AND HEALTH
Efforts to tackle the enormous burden of ill-health in low-income countries are hampered
by the lack of functioning health information structures to provide reliable health statistics.
GIS can be used to map location of health facilities in different locations and their proximity
to the nearest community.
GIS can layer information about endemity of a particular disease in a particular location in
relation to other factors such as environmental conditions.
GIS is used to locate persons with particular health problems therefore the spatial time
series analysis of the spread of the disease and the effects of environmental conditions on
the disease can be known.

8. GIS AND WILDLIFE
Human-caused disruptions, such as habitat loss, pollution, invasive species introduction, and climate change,
are all threats to wildlife health and biodiversity.
Habitat requirements and ranges whereby GIS can be used to show habitat suitability for different species for
example grassland would be more suitable for animals such as zebras and antelope
Population patches and linkages where species interact with one another. The satellite images can show
where populations are dense or scattered and GPS to show the location of the populations.
Population patches and linkages where species interact with one another. The satellite images can show
where populations are dense or scattered and GPS to show the location of the populations
GIS also helps in tracking threatened animals

10. Land management
- land use planning to solve problems such as demolition of structures on road reserves, overlap of land
boundaries, land grabbing and land use conflicts around the country.
- Encourage investments as the issue of distrust and inconclusive title deeds will be addressed through the
use of cadastral mapping
- Citizens will be able to locate properties that meet their needs more easily while conveyancing will be
cheaper and more secure.
- Planners will find it easier to locate suitable places for development and determine the constraints on
their use.
- Governments will be able to tax land and property more equitably and make more informed judgements
where there are competing proposals for land use.
12. Geodemographics
Geo-demographics is the study of population types and their dynamics as they
vary by geographical area.
Information such as population increase or decrease, migratory movement,
losses caused by warfare, spending, lifestyle, town planning, capacity
building, structures can also be accessed and aid in the decision making
process of allocation of resources such as finances to accommodate the
growing population.

21. Property value is a function of location, physical, legal and economic factors.
Traditionally, property valuation depended on valuer's expert knowledge of a locality.
GIS- based property information system is a quantitative approach that involves
analysis of spatial property information.
The database contain all the geographical representation of property information at
the individual property level.
The database is also important for property tax mapping.
22. Limitations of the use of
geoinfromatic systems for data
management efficiency
-Lack of awareness of the potential for GIS to act as anything more than automated map editing systems
-A large effort may be needed to convert existing analog data to digital form, or different digital data types
into a common format.
-Lack of technical capacity to interprate geoinformatic maps and images
-While current GIS are most effective when dealing with static two-dimensional digital map data, many
environmental data sets are inherently 3D, as in solid geology, or even 4D, as with marine and atmospheric
circulation data sets. As a result environmental scientists have developed their own sophisticated systems
for simulation process modelling which often include data capture, storage and display facilities
