# Open Source Software

**Open source software** is a type of computer software that is developed collaboratively and made freely available for anyone to use, modify, and distribute. In recent years, open source software has become increasingly popular in high school education, as it provides teachers and students with access to powerful tools for learning and creativity without the high costs typically associated with proprietary software.

Open source software is particularly valuable in STEAM education, as it allows students to gain hands-on experience with a wide range of tools and technologies used in science, engineering, and mathematics. One of the main advantages of open source software is its flexibility and customizability. Teachers and students can modify and adapt open source software to suit their specific needs and interests, making it a valuable tool for project-based learning and exploration. Open source software also provides opportunities for students to collaborate on software development projects, improving their teamwork and communication skills.

Examples of open source software that are commonly used in high school education include:

* [_**LibreOffice:**_](https://www.libreoffice.org/) a free and open source office suite including word processing, spreadsheet, and presentation software.
* [_**GIMP:**_](https://www.gimp.org/) an image editing software similar to Adobe Photoshop
* [_**Inkscape:**_](https://inkscape.org/) a vector graphics editor
* [_**Blender:**_](https://www.blender.org/) a 3D modeling software
* [_**Audacity:**_](https://www.audacityteam.org/) an audio editing software

Open source software has become increasingly popular in the field of geospatial data analysis and mapping due to its flexibility, affordability, and accessibility. This allows for a collaborative and community-driven approach to geospatial concepts, which can be a valuable learning experience for students who want to explore the world of geospatial data.

Many **open source geospatial tools** are available for analyzing, visualizing, and managing geospatial data, providing opportunities for students to develop valuable skills in these areas. Here is a list some popular open source geospatial tools:

* [_**QGIS**_](https://www.qgis.org/en/site/) is a powerful free and open source cross-platform GIS software that provides a wide range of tools for data analysis, visualization, and mapping and it is widely used by professionals and educators alike.&#x20;
* [_**GRASS GIS**_](https://grass.osgeo.org/) is another open source GIS software that provides a wide range of tools for data analysis, modeling, and visualization.
* [_**GeoServer**_](https://geoserver.org/) is an open source server software that allows users to share and publish geospatial data on the web, and is an excellent tool for creating interactive maps and web-based applications.
* [_**OpenLayers**_ ](https://openlayers.org/)is an open source JavaScript library for displaying and manipulating maps on the web.
* [_**Leaflet**_](https://leafletjs.com/)  is the leading open source JavaScript library for mobile-friendly interactive maps.
* [_**PostGIS**_](https://postgis.net/) is a free and open source spatial database extender for PostgreSQL that enables advanced geospatial queries and analysis.

By using open source geospatial tools in high school education, students can learn important skills and knowledge that are relevant to various fields, such as geography, environmental science, urban planning, and more. Additionally, they can gain exposure to the principles of open source software and the benefits of collaborative knowledge sharing. Another reasons why open source geospatial tools are beneficial for high school education include:

* _**Cost-effectiveness:**_ Open source geospatial tools are free, which makes them accessible to schools with limited budgets.
* _**Customizability:**_ Open source geospatial tools can be customized and adapted to meet specific needs and learning objectives, which allows for greater flexibility and creativity in the classroom.
* _**Openness and transparency:**_ Open source geospatial tools are open for everyone to access, study, and modify. This encourages collaboration, innovation, and knowledge sharing.
* _**Real-world applicability:**_ Many open source geospatial tools are used by professionals in the field, which means that students can gain practical skills and knowledge that can be applied in real-world situations.
* _**Community support:**_ Open source geospatial tools have active communities of users and developers who contribute to their development and provide support for new users.

In conclusion, open source software and geotools provide an accessible and cost-effective way to introduce high school students to the world of geospatial data analysis and mapping. This experience can be enhanced by the use of open data sources and voluntary geographic information (VGI), which provide real-world examples and opportunities for students to engage in meaningful mapping projects.
