Georeferencing
Process of aligning spatial data to a known geographic coordinate system to enable their overlay and analysis in a GIS.
Coordinate Reference System
Standardized reference framework defining how geographic coordinates are specified on Earth, including datum and projection.
Digital Elevation Model
3D digital representation of terrain elevation, excluding surface objects such as buildings and vegetation.
Raster analysis
Set of processing techniques applied to matrix data (pixels) for continuous spatial analysis such as surfaces or gradual phenomena.
Geodatabase
Optimized data structure for storing, managing, and querying vector and attribute geographic information in a structured manner.
Remote sensing
Acquisition of information about objects or phenomena without direct physical contact, typically via satellite or aerial sensors.
Network analysis
Set of algorithms for studying properties and optimizing flows in linear networks (roads, rivers, infrastructure).
WebGIS
Geographic information system deployed on the web enabling access, analysis, and visualization of spatial data via browser.
Kernel Density Analysis
Statistical method smoothing event points to calculate a continuous density surface, revealing spatial concentrations.
Spatially Referenced Information System
Complete infrastructure integrating data, software, hardware and processes to capture, manage, analyze and disseminate georeferenced information.
