In the world of Geographic Information Systems (GIS), the task of digitizing maps and cartographic documents has been essential yet tedious, especially when it involves converting raster images into vector layers. However, technology has made significant strides, and today I am excited to introduce a tool that is revolutionizing this process: the automatic digitization plugin for QGIS using Artificial Intelligence (AI), developed by Bunting Labs.
What is the Automatic Digitization Plugin for QGIS?
This plugin, known as the “Bunting Labs AI Vectorizer,” is an innovative tool that allows QGIS users to automatically digitize lines and polygons, including complex elements like contour lines, with just a few clicks. Using AI algorithms, this plugin can identify and trace lines and shapes with remarkable precision, significantly reducing the time and effort required in the digitization process.
Installation and Usage
Installing the plugin is straightforward:
- Installation: In QGIS, go to the plugins section and search for “Bunting Labs AI Vectorizer.” Install it, and after closing the plugin window, you will see a new icon in the toolbar labeled “Vectorize with AI.”
- Account Creation: The first time you click on the icon, you will be prompted to create a new account with your email address. After confirming your account via the link in your email, you will be ready to start digitizing.
- Digitization: With the plugin activated, select the vector layer you want to work on and enter edit mode. Then, simply click the “Vectorize with AI” icon, click the initial point, and then another point along the line or the edge of the polygon you wish to digitize. The AI will automatically complete the tracing.
Key Features
- For Lines: Ideal for digitizing contour lines or rivers, where you only need to click on key points and the AI takes care of the rest, drawing the complete line with high precision.
- For Polygons: Similar to the process with lines, but applied to the digitization of shapes like lakes, where the AI automatically fills in the interior after tracing the edge.
- Corrections and Adjustments: If the automatic digitization makes mistakes or needs adjustments, you can use the “Shift” key to correct the trajectory, selecting up to where you want the line to have been correctly traced and then continue from there.
This plugin offers a transformative approach to GIS work, making digitization not just faster but also more accessible. It’s a testament to the power of AI in enhancing GIS workflows and a significant leap forward in the field.
