What we will cover: Geometry - * Proximity analysis with improved KNN functionality introduced in PostGIS 2.2 * Geometry dicing for speedier performance in data grouping and proximity analysis, * Geometry clustering Geography - Proximity analysis using KNN (new in PostGIS 2.2) Raster - in-database raster coverage making Topology - geometry simplification that maintains connectedness of adjoining geometries Geocoding and Address Standardization - Basic examples using PostGIS Tiger Geocoder, and address standardizer (new in PostGIS 2.2.)

Areas covered will be: Proximity Analysis Statistical aggregation of data by location Mapping Routing Geocoding Unlikely uses for PostGIS -- non-spatial problems solved by re-imagining the problem as a spatial one. Extra focus on new tricks made possible by PostGIS 2.3+ and PostgreSQL 9.6+.https://videos.pcorp.us/videos/embed/a85e44f1-b294-43d2-89d5-8737d9076c25https://videos.pcorp.us/w/mKjoxAUcLSCQPqFJePHzg8https://videos.pcorp.us/lazy-static/thumbnails/62223fc8-33de-42f2-a151-0ec171a8181d.jpgWriting better PostGIS queries — REGINA OBE, PARAGON CORPORATIONThis presentation will demonstrate ways to take most advantage of spatial indexes, SQL constructs, and PostGIS specific functions. For these exercises we'll be using PostGIS 2.1+ and PostgreSQL 9.3+ . We'll demonstrate common cases people often do inefficiently. This presentation demonstrates the following 1) Various SQL constructs including ANTI join, LEFT, RIGHT, EXISTS, LATERAL, CASE clauses, aggregates 2) What common table expressions (CTEs) are and when to and when not to use them 3) We'll demonstrate these concepts in use in a couple of common spatial query problems - e.g. proximity analysis (both geometry and geography), raster analysis and generation, aggregation of data based on various attributes, other correlation queries.https://videos.pcorp.us/videos/embed/a8031676-e273-4fb1-b5ab-735812eac289https://videos.pcorp.us/w/r7yqEp2ESAgm4KMphVeuuphttps://videos.pcorp.us/lazy-static/thumbnails/1e0f8602-2b45-422f-aaa5-8b1e5d2e61ae.jpgExploring the Many Extensions of PostGIS!Regina Obe from Paragon Corporation presents at PostGIS Day 2021. PostGIS packages six different extensions and there are many others that further extend PostGIS like pgrouting, mobilitydb and ogr_fdw. Regina shows off the postgis_topology tool and she has a nice overview of a sql with geometric output in the form of letters.
