Point clouds have become a foundational data format for modern GIS applications, especially in drone mapping, LiDAR surveys, smart cities, infrastructure planning, mining, and defense. While specialized tools exist for point cloud processing, QGIS now offers powerful native capabilities to visualize and analyze point clouds in 3D—all within an open-source GIS platform. In this blog, […]

Drone mapping has become a core technology across surveying, infrastructure, agriculture, mining, smart cities, and defense applications. While photogrammetry software like Pix4D or OpenDroneMap is used to generate orthophotos and point clouds, QGIS plays a crucial role in visualization, analysis, and delivery of drone mapping outputs. In this blog, we explain how QGIS is used

When building custom GIS applications using the QGIS API and Qt, it’s often useful to show the current mouse coordinates on the map canvas. A common place to display this information is in the status bar. In this post, we’ll look at a minimal example of how to connect the QGIS map canvas (QgsMapCanvas) to

When building a custom GIS application with QGIS API and Qt, one common requirement is to allow users to control how different layers (roads, rivers, boundaries, towns, etc.) are displayed on the map. In this article, we’ll walk through how you can implement a GUI that enables users to: This flexibility ensures that your GIS

Introduction In Geographic Information Systems (GIS), raster data represents information in a grid-based structure such as satellite imagery, aerial photographs, digital elevation models (DEM), or scanned maps. Unlike vector data, which uses points, lines, and polygons, raster data provides continuous coverage across a geographic area. QGIS, one of the most powerful open-source GIS platforms, provides
