Information Density: PostGIS – Signal Evidence & AI Readability

Information Density — The Lens

Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.

Info Density Power-words vs. Substance ratio.

Information density is exceptionally high across all examined pages. H1 headings like [H1] Source Code and [H1] About PostGIS lead directly into technical feature lists and specific version numbers (e.g., PostGIS 3.6.3). The body text is devoid of power words, opting instead for technical nouns like ‘multi-geometries,’ ‘raster data,’ and ‘SFCGAL 1.4+.’

Information Density is read straight from the body copy: how much of the text carries grounded, checkable substance versus hollow filler. Below is the clean text the engine analyzed, then the industry’s known generic-claim patterns to weigh it against.

Spatial Indexing: Quickly search and retrieve spatial data based on its location.
Spatial Functions: A wide range of spatial functions that allow you to filter and analyze spatial data, measuring distances and areas, intersecting geometries, buffering, and more.
Geometry Processing: Tools for processing and manipulating geometry data, such as simplification, conversion, and generalization.
Raster Data Support: Storage and processing of raster data, such as elevation data and weather data.
Geocoding and Reverse Geocoding: Functions for geocoding and reverse geocoding.
