The QGIS Plugins website has undergone a major redesign to enhance usability and provide a seamless experience for users. With a modernised interface and improved navigation, users can now find and manage plugins more efficiently. Some of the key updates include:

1. A fresh UI that matches the latest QGIS branding.
2. Enhanced browsing experience with better categorisation of plugins.
3. Detailed plugin pages showcasing ratings, download counts, and descriptions more clearly.
4. Improved search and filtering options to find the right plugin quickly.
5. A more intuitive submission process for plugin developers.

Introducing QGIS Hub

QGIS Hub Homepage

In addition to the plugin update, we are thrilled to introduce the QGIS Hub, now available at https://hub.qgis.org. This new platform serves as a dedicated space for sharing QGIS resources such as styles, 3D models, geopackages projects files, QGIS Layer Definition (QLR) files, and much more. By separating this section into its own website, we have made it easier for users to discover and access valuable resources.

 Key features of the QGIS Hub include:

1. A visually appealing homepage with featured resources.
2. A well-organised list view for browsing available assets.
3. Detailed resource pages with previews and descriptions.
4. Advanced search functionality to quickly locate specific resources.
5. A seamless submission process for users who wish to contribute their resources.

Thank you to the QGIS Community

QGIS is developed by a team of dedicated volunteers, companies and organisations. The QGIS project relies on sponsorships and donations for much of their funding. Without the contributions of the QGIS sustaining members and donors and all volunteers, these continued improvements would not be possible. At Kartoza we are fortunate to employ both a QGIS Document Writer and QGIS Developer as fulltime staff members, an achievement made possible through the donations from QGIS community. Thank you to Tim Sutton (member of QGIS Steering Committee) for donating his time and helping make these updates possible.

Experience the New Platforms Today!

We invite you to explore the new QGIS Plugin website and the QGIS Hub today. These updates are designed to enhance your workflow and make it easier to extend and enrich your QGIS experience. We look forward to your feedback and continued support as we work to improve the QGIS ecosystem!

Enhancing Disaster Management with QGIS and the InaSafe Plugin

In the ever-evolving landscape of disaster management, having the right tools to anticipate and respond to disasters can be the difference between preparedness and chaos. One such tool that has been making waves is InaSafe, an open-source plugin for QGIS designed to produce realistic natural hazard impact scenarios for better planning and response.

At the GISSA Gauteng session earlier this year, I demonstrated how InaSafe can empower disaster management professionals. My talk focused on how the tool can be used in practical, real-world scenarios, specifically through the analysis of flood events. Here’s a breakdown of my key points and insights from the session.

What is InaSafe?

InaSafe is a plugin that allows users to conduct impact assessments based on hazard and exposure data, like floods, earthquakes, or volcanic eruptions. The tool was developed to provide actionable information to help in making informed decisions during disaster management planning. One of InaSafe’s most powerful aspects is its ability to model different disaster scenarios and provide detailed analyses of their impacts on communities, infrastructure and the environment.

The Power of Simple and Complex Analyses

During the session, I performed two different types of flood analysis to highlight the versatility of InaSafe.

Key Benefits for Disaster Management

1. Real-World Applications: InaSafe isn’t just theoretical—it’s actively used in disaster-prone regions around the world, from Southeast Asia to Africa. Governments, NGOs, and disaster response teams leverage it to improve preparedness and risk mitigation strategies.
2. Customisable Outputs: InaSafe allows users to generate tailored impact reports. These reports can include detailed statistics, maps, and charts, making it easy to communicate risks and necessary actions to decision-makers and stakeholders.
3. Community Driven: The tool is open-source and free, with a global community contributing to its development. This ensures that InaSafe stays up to date with the latest disaster management needs and best practices.

How to Get Started with InaSafe

If you're interested in exploring the power of InaSafe for your own disaster management needs, here’s a simple guide to get started:

Install the Plugin: InaSafe is available as a free plugin in QGIS. You can install it directly through the QGIS plugin manager.

Explore the Plugin: Familiarise yourself with the tool by exploring the various hazard and exposure datasets available.

Conduct a Simple Analysis: As demonstrated in the session, start with a basic hazard layer (e.g., flood, earthquake) and use the plugin to assess impacts on your region of interest.

Dive Deeper with Complex Analyses: For those looking to conduct more advanced studies, InaSafe supports custom inputs, more detailed parameters and sophisticated simulations.

1. Simple Analysis

We began with a basic flood scenario, demonstrating how easy it is to run an analysis using InaSafe once the plugin is installed in QGIS. For this exercise, I used predefined hazard and exposure layers, quickly generating an impact report. The simplicity of this analysis underscores InaSafe's accessibility for users, even those new to QGIS or GIS analysis. In just a few clicks, you can produce meaningful insights about potential flood impacts, helping first responders prioritise actions.

2. Complex Analysis

I then shifted to a more intricate analysis, integrating multiple datasets and refining parameters to simulate a more realistic and high-stakes flood scenario. This demonstrated InaSafe's capacity to handle complex scenarios where greater detail is needed—such as assessing the potential displacement of populations, the impact on critical infrastructure like roads and hospitals, or the number of affected households. The results of these analyses showed the breadth and depth of InaSafe’s capabilities. The tool can be used to assess anything from small, localised events to large-scale disasters with widespread impacts.

Wrapping Up

As we face an increasing number of natural disasters, tools like InaSafe are essential in helping us prepare, respond, and ultimately save lives. Whether you're a GIS professional or a disaster management planner, InaSafe provides a powerful, accessible platform to better understand the impacts of disasters before they strike. With its combination of simplicity and depth, it’s a tool that can truly transform the way we approach disaster management.
