Feasibly the most significant concern for all of us today is shielding the environment in which we live and breathe. Today, well-developed GIS systems are used to protect the environment. The GIS has become an integrated, well developed, and successful tool in disaster management and mitigation. GIS can help with risk management and analysis by displaying which areas are likely to be prone to natural or man-made disasters.

Let us turn our attention for a little while to the GIS system. Before we begin, let us define this system.

A Geographic Information System (GIS) is a system of computer software, hardware and data; personnel that make it possible to enter, manipulate, analyse, and present data, and the information that is tied to a location on the earth’s surface. (Thurgood, 1995)

At the Environmental Protection Agency, the GIS Unit is responsible for mapping and identifying critical points. These can then be used to help ascertain geographic or spatial information, which in turn helps the staff understand the complex interrelationships of natural resources and human population as they relate to potential or known pollution sources of a project. This additional information is beneficial to us in accomplishing our mission of protecting human health and the environment.

GIS can also display and analyse aerial photographs. This is a critical part in analysing digital information which can be overlaid on photographs to provide environmental data analysts with more familiar views of landscapes and associated data. GIS can provide a quick comparative view of hazards (highly prone areas), risks (areas of high risk which may occur), and areas to be safeguarded; and this is very essential as it relates to the work at the EPA.

With the help of GIS information, the Agriculture and Forestry Departments at the EPA can now adequately manage the forest activities, and ensure that developers are complying with their permit conditions.

With all that said, let us be taken away with the fact that the use of GIS data has a profound impact on business and industry, as well as on the general public. If the technology were eliminated, we would realise, to a great extent, the overarching importance of GIS data in our daily lives and at work.

GIS DAY 2021

GIS Day is a worldwide event that celebrates the technology of Geographic Information Systems (GIS). The day was started in 1999 by Ralph Nader, and was intended for geography awareness. Here are some tips, courtesy of, to celebrate GIS Day.

GEOCACHING – Pull out your GPS or phone, because it’s time to go geocaching. This is a fun activity in which you track down treasures, and you can include anyone.

OPENSTREETMAP – The OpenStreetMap movement has the power to move mountains (literally). Join the OpenStreetMap team and map out your part of the world. Who knows, you could even learn something new about it.

SATELLITE VIEWING – Silently, satellites orbit our Earth for a range of remote-sensing applications & uses. If you don’t have a telescope, then you can use your phone as a satellite-augmented reality app. Point it to the sky and discover new satellites.

GOOGLE EARTH – Who doesn’t like to spin the globe in Google Earth? Now, the location-based application built by Google lets you tour the world without physically being there.

ESRI STORY MAP – Whatever it is that you decide to do on GIS Day, tweet it for the world to see. Of course, Esri will add it to their GIS Day story map to see where and how many are involved in the celebration.
