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 […]

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

At Manya Technologies, we develop custom GIS tools using the powerful QGIS C++ API, integrated seamlessly into Qt interfaces. One essential feature in any GIS viewer is the ability to manage map layers interactively — that’s where the Layer Tree View comes in. In this post, we share a working example of how to implement
