What You'll Need
Before we dive into the step-by-step process, here's what you'll need:
1. QGIS Software: Make sure you have QGIS installed on your computer. You can download it for free from the official website.
2. GIS Data You'll need spatial data to create your map. QGIS supports a wide range of data formats, including shapefiles, GeoJSON, and more.
3. Web Hosting You'll need a web hosting service to publish your map online. Many options are available, from free services like GitHub Pages to paid hosting platforms.
4. Basic HTML/CSS Knowledge: While not mandatory, some familiarity with HTML and CSS will be helpful for customizing the appearance of your web map.
1. Open QGIS and load the data layers you want to display on your web map.
2. Ensure that your data is projected correctly. Web maps typically use the WGS 84 (EPSG: 4326) or Web Mercator (EPSG: 3857) coordinate systems.
Step 2: Install and Configure the QGIS2Web Plugin
1. In QGIS, go to the 'Plugins' menu and select 'Manage and Install Plugins.'
2. Search for 'QGIS2Web' and click 'Install.' This plugin will help you export your map for the web.
3. Once installed, you can find the QGIS2Web plugin in the 'Web' menu.
Step 3: Customize Your Web Map
1. In the QGIS2Web plugin, you can customize various aspects of your web map, such as the base map, layer styling, and pop-up information.
2. Adjust the settings according to your preferences and project requirements.
Step 4: Export Your Web Map
1. After customizing your web map, click the 'Create a web map' button in the QGIS2Web plugin.
3. Specify the output folder where your web map files will be saved.
Step 5: Publish Your Web Map
1. Upload the contents of the output folder to your web hosting service. This typically involves using an FTP client or an online file manager provided by your hosting provider.
2. Ensure that your main HTML file (e.g., index.html) is in the root directory of your hosting space.
Step 6: Share Your Web Map
1. Once your files are uploaded, access your web map by visiting the URL of your hosted HTML file.
2. Share this URL with others to showcase your interactive QGIS map on the web.
Step 7: Additional Customization (Optional)
1. If you want to further customize the appearance and behaviour of your web map, you can edit the HTML and CSS files generated by QGIS2Web.
Displaying QGIS map layers on a web page is an excellent way to share your geographic data and insights with a broader audience. With the help of the QGIS2Web plugin and some basic web hosting knowledge, you can create interactive and informative web maps that engage your viewers. As you gain more experience, you can explore advanced features and expand your GIS capabilities.
