4 KudoZ points awarded for this answer. Comment: "Thanks Fuad and Orientation. I used "geographical coordinates" in the translation, but after some reading I think "real-world [with geographical implied] coordinates" would have been more precise. These definitions were helpful: "Data capture: The process by which data are taken from the real-world (primary source), or from a secondary source such as a paper map, and entered into GIS software. From primary data this is usually through the use of Global Positioning Systems or remote sensing. For secondary data it is usually through digitising or scanning." "Primary source: In GIS terms this usually means a digital data source that is derived directly from the real world such as through Global Positioning Systems or remote sensing.""
