Geocoding
Process of converting postal addresses or location descriptions into precise geographical coordinates (latitude and longitude) to enable spatial analysis.
Georeferencing
Technique of aligning spatial data with a standard geographic coordinate system to ensure accurate location on the Earth's surface.
Spatial buffer
Geometric buffer zone created around a point, line, or polygon at a specified distance, used to analyze proximity relationships.
Spatial cluster analysis
Statistical detection of groupings of points or geographic features exhibiting similar characteristics or unusual concentration in space.
Spatial interpolation
Method of estimating values at unsampled positions based on known values from neighboring points, thus creating continuous surfaces.
Geographic Information System
Specialized software platform for capturing, storing, analyzing, and visualizing georeferenced data for spatial decision-making.
Cartographic projection
Mathematical transformation converting the Earth's spherical coordinates into two-dimensional planar representations while preserving certain geometric properties.
Hotspot analysis
Statistical identification of areas showing significantly high concentration of events or values compared to the expected spatial distribution.
Spatial Join
Operation combining attributes from datasets based on their geographic relationships, such as intersection, containment, or spatial proximity.
Spatial Autocorrelation
Statistical measure quantifying the degree of correlation of a variable with itself across space, revealing patterns of clustering or dispersion.
Spatial Weighting
Assignment of weights to geographic observations based on their distance or spatial relationship, essential for local spatial analysis models.
Voronoi Diagram
Partition of the plane into convex regions where each region contains all points closer to a given reference point than to any other point.
Delaunay Triangulation
Division of a set of points into non-overlapping triangles maximizing minimum angles, thus optimizing geometric properties for interpolation.
Rasterization
Conversion of vector data (points, lines, polygons) into a regular grid of pixels with attribute values, facilitating continuous space analysis.
Polygonization
Transformation of raster data into polygonal vector structures, identifying homogeneous areas based on value or continuity criteria.
Network Analysis
Study of topological properties and flows in geographic networks (roads, rivers, infrastructure) to optimize routes and accessibility.
Spatial Distance Matrix
Square data structure containing calculated distances between all pairs of geographic points, fundamental for proximity analysis.
Moran's I
Statistic measuring global spatial autocorrelation, indicating whether similar values tend to cluster (positive) or disperse (negative).
Geohashing
System for encoding geographic coordinates into a hierarchical character string, enabling efficient spatial searches and proximity indexing.
Kernel Density Analysis
Non-parametric estimation method calculating point density using a kernel function to smooth the spatial distribution of events.
