Spatial extract, transform, load (spatial ETL), also known as geospatial transformation and load (GTL), is a process for managing and manipulating geospatial data, for example map data. It is a type of extract, transform, load (ETL) process, with software tools and libraries specialised for geographical information.[1]
A common use of spatial ETL is to convert geographical information from a data source into another format that can be more easily used, for example by importing it into GIS software.[1] A tool may translate data directly from one format to another, or via an intermediate format. Intermediate formats are often used when data transformation must be carried out.
