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. It can store the location, shape, and attributes of geographic features. 

Vector Data: Data that represents geographic features with points, lines, and polygons. Examples include city locations (points), rivers (lines), and country boundaries (polygons). 

Coordinate Reference System (CRS): A coordinate-based system used to locate geographical entities. It defines how the two-dimensional, projected map in your GIS relates to real places on the earth. 

Symbology: The use of symbols to represent different types of data on a map. This includes colors, shapes, and sizes to differentiate between various features. 

Attribute Table: A database or tabular file containing information about a set of geographic features, usually linked to the features 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, such as a comma or tab. Often 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 elements like scale bars, north arrows, legends, and coordinate grids. 

Gridlines: Lines on a map that represent intervals of latitude and longitude, helping to provide a 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.
