If you’re new to the world of Geographic Information System (GIS), you may find it challenging to understand what it is and how it can benefit you. Simply put, GIS is a system designed to capture, store, manipulate, analyze, manage and display geographically-referenced data. In simpler terms, GIS is like a digital map that allows people to visualize features and patterns on the Earth’s surface. In this beginner’s guide, we’ll take a closer look at GIS and how you can get started with it.
What is GIS?
GIS is a technology that has been around for over 50 years and is used in a variety of industries today, such as government, natural resources, environmental planning, and more. GIS allows users to capture and analyze geographic data in a way that traditional data processing tools can’t. It’s becoming an increasingly important tool, as more and more organizations recognize the value of analyzing information on a map.
Getting started with GIS
To start with GIS, you’ll need some software that allows you to create, manipulate, and analyze geographical data. There are many software options available, but the most commonly used ones are ArcGIS and QGIS. ArcGIS is a proprietary program that requires a license, while QGIS is an open-source program that is free to download and use.
Once you have the software installed, you can start exploring the interface and learning the basic functions. It’s important to note that while GIS software can be user-friendly, there is a learning curve involved. You may need to invest some time and effort to get comfortable with the program, but once you do, you’ll find that working with geographical data is fun and rewarding.
Applications of GIS
GIS has numerous applications in various industries. Here are some examples:
– In environmental planning, GIS can be used to analyze the environmental impact of land-use changes, track wildlife movements, and identify areas where conservation efforts are needed.
– In urban planning, GIS can be used to analyze traffic patterns, identify areas at risk of flooding, and assess the impact of new developments on the environment.
– In emergency response, GIS can be used to track the spread of diseases, plan emergency evacuations, and determine the best routes for emergency vehicles.
Final thoughts
GIS is a powerful technology that has become an essential tool in many industries. Whether you’re a student or a seasoned professional, learning GIS can help you gain a deeper understanding of spatial data and provide you with a competitive edge in the job market. If you’re interested in getting started with GIS, download a free software and start exploring the possibilities it offers. With some effort and practice, you’ll be amazed at what you can achieve with GIS.
