Iyini idatha yezwe?
Idatha nolwazi lwezendawo, olwaziwa nangokuthi idatha ye-geospatial, ichazwa ochungechungeni lwezindinganiso ze-ISO/TC 211 njengedatha nolwazi olunokuxhumana okungacacile noma okucacile nendawo ehlobene noMhlaba (indawo yezindawo noma isikhundla sezindawo). Ibizwa nangokuthi idatha ye-geospatial kanye nolwazi, idatha ye-georeferenced kanye nolwazi, kanye ne-geodata kanye ne-geoinformation.  Cishe u-90% wemithombo kahulumeni yedatha unengxenye yendawo. Ulwazi lwendawo (olwaziwa ngamagama amaningi ashiwo lapha) lugcinwa ohlelweni lolwazi lwendawo (i-GIS).  Kukhona nezinhlobo eziningi ze-geodata, kuhlanganise amafayela we-vector, amafayela we-raster, ama-database e-geographic, amafayela e-web, kanye nedatha ye-multi-temporal.  Idatha yendawo noma ulwazi lwendawo luhlobo olubanzi lwedatha olunejometri efanelekile kepha aluhambisani ne-georeferenced, njengakwi-computer-aided design (i-CAD), bheka ukumodeliswa kwejometri.
