Abstract This note suggests that decimal latitude/longitude [dLL] locations should be used to identify features of interest, landforms, sample and investigations sites, in an ‘information landscape’ provided by the geomorphological literature. All information associated with a labelled, or tagged, geolocation available for examination as part landscapes can explored represented books, papers other publications. also outlines ‘open’ FAIR data are findable, accessible, interoperable reusable how principles better explain landscapes, especially mountain landscape domain. Tors rock glaciers illustrate sites inform fieldwork literature searching. Any [dLL]‐specified location is identifying label, names given landforms toponyms. Two letters (digraph) landform labels: TO tors RG glaciers. Citations, (author–date–title–source) attributions, labels. The shows these attributions linked geolocations specifying time space addition will facilitate future searches modelling explore ‘unknowns’ landscape, this paper ways which achieved, including geoheritage geotourism.

The essential aspects of Gore’s “Digital Earth” concept include “georeferenced” data. This paper is concerned with establishing the need for a standardised and common form to locate points on earth’s surface. Rather than degree, minute, second (dms) system latitude/longitude location, decimal degree system, formatted as comma separated variable tuple in square brackets, [dLL], advocated. Values, an appropriate number places, can be inserted text computer searchable. [dLL] also becomes metadata data set or index databases identifiers images. Various uses this are illustrated. allows become more “open” via FAIR principles: findability, accessibility, interoperability, reusability. Wider use earth sciences fundamental collaboration other disciplines, especially Critical Zone Science. general geolocation exploited wide variety analytical methodologies, some which outlined, science environmental situations.

Satellite imagery has become a major source for identifying and mapping terrestrial planetary landforms. However, interpretating landforms their significance, especially in changing environments, may still be questionable. Consequently, ground truth to check training models, mountainous areas, can problematic. This paper outlines decimal format, [dLL], latitude longitude geolocation that used model interpretation validation data sets. As have positions space time, [dLL] defined points, as images, associated with metadata nodes. Together vertices, nodes help build ‘information surfaces’ part of the Digital Earth. examines aspects Critical Zone integration via FAIR principles, are; findable, accessible, interoperable re-usable. Mapping making inventories rock glacier are examined context geomorphic environmental significance need geolocated truth. Terrestrial examination glaciers shows them predominantly glacier-derived not indicators permafrost. Remote-sensing technologies track developing surface features show climatically melting beneath debris covers. Distinguishing between glaciers, debris-covered over time is challenge new remote sensing satellites necessity common format report many Earth features.
