MAPPING SOFTWARE PART I – QGIS

What is Geographic Information Systems (GIS)?

Geographic Information Systems (GIS) are computer tools that help us view and analyze maps and geographical data. These systems allow you to layer different types of information, like boundaries, elevation models, points of interest, onto maps to answer various questions, such as “Where’s the best place to build a business?” or “How might a flood impact a neighborhood?”.

QGIS: A Free and Open Source Geographic Information System

One notable GIS tool is QGIS, an open-source GIS software, that enables you to visualize and manipulate spatial data. Being open-source means it’s freely accessible to everyone, and importantly, it’s free to use.

QGIS Functions

QGIS allows you to perform a wide range of tasks related to mapping and spatial analysis. One of its basic operations is data visualization: you can import various types of geographic data, such as points, lines, and polygons, and display them on a map. These could be anything from locations of schools to the boundaries of barangays. Moreover, the software provides tools for more complex tasks like measuring distances and areas, and even performing analyses to identify patterns or solve problems. For instance, you could use QGIS to find the shortest path between two locations considering various obstacles, or to identify areas at high risk for flooding. All these features make QGIS a versatile tool for anyone interested in understanding the world in a spatial context.

As a Database Management Tool

QGIS is like a digital toolbox for maps. Imagine having a spreadsheet or a table full of places and details, and you want to see them on a map. With QGIS, you can take that information and connect it directly to a map. It helps turn your lists of locations from spreadsheets into visual points on a map. So, not only can you create and explore maps with QGIS, but you can also link your data tables to make your maps more informative. It’s a handy way to see your data come to life on a map, making it easier to understand and analyze.
