What is geofencing? A geofence is a virtual boundary on a map that triggers automatic actions when a device enters or exits it. This beginner-friendly explainer covers how GPS, Wi-Fi, and cellular positioning power it, active vs passive types, real use cases, and how it differs from geotargeting.

A QR code menu ends the reprint cycle for small restaurants: update the menu once online and every table shows the new version. This step-by-step guide covers hosting the menu, static versus dynamic codes, printing, and placement.

A scanned paper map is just a picture until you tie it to real coordinates. This beginner's guide walks through QGIS Georeferencer: control points, transformation settings, and how to check your result.

Contour lines are the most useful feature on a topographic map for a hiker. Learn what their spacing and shape tell you about steepness, valleys, ridges, and summits before your first hike.

Free satellite imagery from Sentinel-2 and Landsat is enough for most beginner GIS projects. This guide walks through choosing a source, picking a cloud-free scene, and loading it into QGIS.

NDVI maps turn red and near-infrared satellite bands into a single greenness score from -1 to 1. Learn what high, low, and negative values really show, and which mistakes make beginners misread them.

Sentinel-2 offers sharper 10-metre imagery and five-day revisits; Landsat offers a deeper archive back to the 1970s. Compare resolution, revisit time, bands, and licensing to pick the right one for your project.

Shapefiles suit desktop GIS, GeoJSON suits web maps and data exchange, and KML suits Google Earth visualisation. Compare what each format carries, where it breaks, and which to choose.

A digital elevation model, or DEM, is a raster grid of ground heights. Learn how DEMs are made, what resolution means for slope and watershed work, and how to try one in QGIS.

OpenAerialMap collects openly licensed drone and aerial imagery from volunteers around the world. Learn how to search it, check licences and resolution, and use what you find in QGIS.
