GISid
GISid, short for Geospatial Information System Identifier, is a concept describing a persistent, globally unique identifier assigned to geospatial resources such as datasets, map services, raster layers, and related metadata. The aim is to enable stable citation, precise referencing, and interoperability across GIS tools, data catalogs, and spatial data infrastructures.
There is no single universally adopted GISid standard. The idea is discussed within data-citation initiatives and
A typical GISid would be composed of components that may be separated by colons or other delimiters,
Implementation would rely on registries that manage the namespace and assign new identifiers, and on resolvers
Benefits include improved data citation, provenance tracking, and interoperability across platforms. Challenges involve governance, namespace fragmentation,
