However, before we dive into explaining how to learn GIS, it is also important to understand what GIS and the geospatial industry entails
The geospatial industry is a multi-dimensional industry that is made up of research and academic institutions, governmental parastatals and agencies, profit and non-profit companies, private and public institutions that uses and employ the use of location intelligence and geospatial technology to solve problems, and also, formulate policies in a sustainable way.
These industries rely on GIS to effectively operate and develop policies. GIS, as defined by multiple experts, is a powerful system that enables the capture, storage, and visualization of spatial information pertaining to the Earth and its inhabitants. What sets GIS apart is its ability to accommodate various types of data within its framework, making it a multi-dimensional tool. For instance, demographic data like population density, education level, and income level can be seamlessly represented and stored in GIS.
GIS is made up of several components such as software, hardware, people, data, and methods. The integration of these components is what enables the system to effectively solve problems.
This is the component on which the computer system which operates on, it ranges from GPS devices, data collection instruments, computers others. The choice of the sophistication of the hardware depends on the intended applications.
GIS software provides the enabling environment and tools required to edit, analyze, store, visualize, and present spatial and geographic data. The software components provide the tools for spatial data entry and manipulation, creation, and management of spatial databases, and tools that also support spatial queries of all forms. They also provide a graphical user interface that enables users to access these tools effectively. Some of these software include QGIS, ArcGIS, and GRASS GIS among several others.
Spatial and non-spatial data are one of the most central and essential components of a GIS. A GIS essentially integrates spatial and non-spatial data, storing them in a database for manipulation and visualization.
Also central to the deployment of a GIS are the people who manage and develop tools, plans, and systems using GIS to solve problems. This includes GIS technicians, analysts, developers, and even others who are non-GIS savvy.
GIS is methodologically driven. It operates based on well-defined methods for querying, editing, analyzing, and storing geospatial data.
