QGIS

An open-source Geographic Information System (GIS) application that allows users to create, edit, visualize, analyze, and publish geospatial information.

Raster Data

A type of digital image represented by reducible and enlargeable grids. Each cell in the grid contains a value representing information, such as temperature or elevation.

Digital Elevation Model (DEM)

A 3D representation of a terrain's surface created from terrain elevation data.

Shapefile

A popular geospatial vector data format for geographic information system (GIS) software, storing location, shape, and attributes of geographic features.

Vector Data

Data that represents geographic features with points, lines, and polygons, such as city locations (points), rivers (lines), and country boundaries (polygons).

Coordinate Reference System (CRS)

A coordinate-based system used to locate geographical entities, defining how the projected map in GIS relates to real places on earth.

Symbology

The use of symbols to represent different types of data on a map, including colors, shapes, and sizes to differentiate between features.

Attribute Table

A database or tabular file containing information about a set of geographic features, usually linked by a unique identifier.

Identify Features Tool

A tool in GIS software used to click on a map feature and retrieve information about it from the attribute table.

Delimited Text Layer

A layer created from a text file where data fields are separated by a delimiter, used for importing point data with coordinates.

QuickMapServices Plugin

A plugin for QGIS that allows users to quickly add basemaps and other map services to their projects.

Raster Layer

A layer in GIS that represents raster data, such as satellite imagery or digital elevation models.

Singleband Pseudocolor

A rendering type in QGIS used for visualizing single-band raster data with a color gradient.

Print Composer

A tool in QGIS used to create map layouts for printing and publication, including scale bars, north arrows, legends, and coordinate grids.

Gridlines

Lines on a map that represent intervals of latitude and longitude, providing reference for the location of features.

Scale Bar

A graphical representation of distance on a map, helping users understand the scale of the map.

North Arrow

A symbol on a map that shows the direction of north, helping users orient themselves.

Legend

A key on a map that explains the symbols, colors, and patterns used to represent different data layers.

Inset Map

A smaller map included within the main map to show a larger area of context or a different scale.

Python

A programming language commonly used for scripting in QGIS to automate tasks and enhance reproducibility.
