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.

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.

WGS84 gives global latitude and longitude; UTM gives local metres in zones. Learn when each system helps, why layers misalign when they mix, and how to set the right CRS in QGIS.

A choropleth map shades areas by a data value, such as population or rainfall. Follow a beginner workflow in QGIS: prepare clean data, choose a classification, pick a honest colour ramp, and label the result.

A step-by-step guide to downloading Sentinel-2 imagery into QGIS: account setup, smart searching by cloud cover, choosing Level-2A data, and loading the right band combinations.

NDVI turns satellite imagery into a plant-health map in minutes. Learn the formula, which Sentinel-2 and Landsat bands to use, and how to style and interpret the result honestly.

Turn a drone elevation model into readable contour lines in QGIS. Learn how to prepare the DEM, choose the right interval, style index contours, and check accuracy.

QGIS is free and powerful, but beginners need a clear path. This step-by-step tutorial covers installing, adding data, styling, querying, and exporting your first map.

QGIS print layouts add titles, legends, scale bars, and clean design to your map. Here is how to build, style, and export a professional layout.

Georeferencing gives a scanned old map real coordinates so it can be compared with modern data. Here is how to pick control points, transform, and check the result in QGIS.
