Getting started with GIS: A beginner's guide to geographic information systems

Geographic Information Systems (GIS) have become indispensable tools for analyzing, visualizing, and understanding spatial data across various fields, from urban planning and environmental management to mining and construction. If you're new to GIS and eager to explore its potential, this beginner's guide will provide you with the essential knowledge to get started.

‍

What is GIS?

‍

At its core, GIS is a technology that allows users to capture, store, manipulate, analyze, and visualize spatial data. This data can include information about features on the Earth's surface, such as locations, attributes, boundaries, and relationships. GIS enables users to gain insights into spatial patterns, make informed decisions, and solve complex problems by integrating and analyzing different layers of spatial information.

Key Components of GIS

‍

1. Spatial Data

‍

The foundation of GIS is spatial data, which represents the geographic features of the Earth's surface. Spatial data can be divided into two main types: vector data and raster data. Vector data represents discrete features as points, lines, and polygons, while raster data represents continuous phenomena as grids of cells.

‍

2. Software

‍

GIS software provides the tools and functionality for creating, editing, managing, analyzing, and visualizing spatial data. There are many GIS software packages available, ranging from open-source solutions to commercial, high-cost software. Birdi falls in the middle: we’re an easy-to-use, affordable, cloud-based GIS software (Book a demo to see our platform in action).

‍

3. Hardware 

‍

In addition to software, GIS requires hardware such as computers, tablets, or smartphones. Some GIS solutions require you to run their applications locally on your computer, whereas cloud-based software like Birdi runs on any device or browser. What’s more, depending on your data capture methods, you might need hardware like drones, 360 panoramic camera, smartphone/DSLR or pole camera.

4. People 

‍

GIS is not just about technology — it also involves people with the skills to use GIS tools effectively. While GIS professionals, including analysts, technicians, and developers, play a crucial role in collecting, analyzing, and interpreting spatial data to address real-world challenges, easy-to-use software like Birdi really enables anyone to benefit from GIS data.

Getting started with GIS

‍

1. Learn the basics: Familiarize yourself with the fundamental concepts of GIS, including spatial data types, coordinate systems, projections, and data formats. Online tutorials and GIS courses can provide a solid foundation for beginners (plus, check in on our blog! We’ll continue to post helpful articles.
2. Explore GIS software: You can test out the various GIS software out there and see what best fits your needs. If you’d like to see if Birdi is a fit for you, you can book in a demo with us, or request access to our platform. You’ll get to see all of our features in action and how we might
3. Capture geospatial data: Once you’re ready, start capturing geospatial data with your chosen capture method (e.g. drone, smartphone, 360 camera etc).
4. Create your first map: Use GIS software to create your first map by uploading your geospatial data. From there, you can process it into outputs like orthophotos, digital elevation models and point clouds, and visualize it all on the map exactly where it was captured from.
5. Generate insights: Explore your data, annotate, inspect assets and generate reports to gain insights about your sites and locations.
6. Join GIS communities: Engage with the GIS community by joining online forums, discussion groups, and social media channels where GIS professionals and enthusiasts share knowledge, resources, and best practices. (Geoawesomeness is a great place to start! They recently named Birdi in their top 100 global geospatial companies).
