This article shows how to remove duplicate vertices/point in SQL Server Spatial geometry objects.
This post generates and visualizes all the topological relationships possible between two linestrings.
This article describes how to repackage the functionality in the SDO_LRS package via an PL/SQL object to provide a cleaner neater API.
This article shows how to construct a function that allows any linestring to be split by any point using a collection of SDO_LRS procedures and functions.
This article describes how to split a linestring or a multilinestring using PL/SQL at a known point.
This article shows how to use GeoRaptor’s Jump to Geometry functionality to conduct “one off” mapping of SDO_GEOMETRY and EWKT/WKT text objects. PostGIS is shown as a source for EWKT showing how to integrate development across multiple databases.
This article shows how to snap a point to an Oracle Spatial linear geometry using the SDO_CLOSEST_POINTS procedure and function
