Georeferointi tarkoittaa prosessia, jossa kaksiulotteiselle tai kolmiulotteiselle aineistolle, kuten kartoille, ilmakuville, pistepilville tai 3D-malleille, liitet\u00e4\u00e4n sijaintitiedot todellisessa koordinaattij\u00e4rjestelm\u00e4ss\u00e4 (esim. WGS84, ETRS89). N\u00e4in aineisto voidaan asemoida tarkasti maapallon pinnalle.<\/p>\n\n\n\n

Georeferoinnissa k\u00e4ytet\u00e4\u00e4n tunnistettavia pisteit\u00e4, kuten maastokohteita, mittapisteit\u00e4 tai tunnettuja koordinaatteja, jotka yhdistet\u00e4\u00e4n vastaaviin sijainteihin kartalla tai paikkatietoj\u00e4rjestelm\u00e4ss\u00e4. Kun aineisto on georeferoitu, se voidaan yhdist\u00e4\u00e4 muihin paikkatietoaineistoihin, analysoida GIS-j\u00e4rjestelmiss\u00e4 tai hy\u00f6dynt\u00e4\u00e4 muun muassa maanmittauksessa, infrastruktuurisuunnittelussa ja digitaalisten kaksosten k\u00e4yt\u00f6ss\u00e4.<\/p>\n\n\n\n

Georeferointi on keskeinen vaihe silloin, kun 2D- ja 3D-aineistoja, kuten laserkeilauksia, drone-kuvia tai rakennussuunnitelmia, halutaan k\u00e4ytt\u00e4\u00e4 osana paikkatietopohjaisia prosesseja. Se mahdollistaa esimerkiksi karttojen yhdist\u00e4misen, omaisuuden sijaintiseurannan, ymp\u00e4rist\u00f6mallinnuksen sek\u00e4 muutosten tunnistamisen ajan kuluessa.<\/p>\n\n\n\n
