Fasahar Auna Nauyin Gravimetric
Ana yin ma'aunin nauyi ta amfani da na'urar da ake kira gravimeter. Gravimeter kayan aiki ne mai matuƙar tasiri wanda zai iya auna ƙananan canje-canje a fagen nauyi na duniya. Akwai manyan nau'ikan gravimeter guda biyu: gravimeters masu alaƙa da kuma gravimeters masu daidaito. Gravimeters masu alaƙa suna auna bambanci a cikin nauyi tsakanin maki biyu, yayin da gravimeters masu daidaito suna auna cikakken ƙimar ƙarfin nauyi a wuri ɗaya tare da babban matakin daidaito.
Ma'aunin nauyi yana buƙatar matakai masu kyau don guje wa kurakurai, duka dangane da dabarun aunawa da tasirin muhalli na waje. Ana bin waɗannan matakai gabaɗaya a cikin ma'aunin nauyi:
1. Daidaita Kayan Aiki: Dole ne a daidaita na'urar auna nauyi kafin a auna ta don rage kurakuran tsarin aiki.
2. Daidaita Wurin: Dole ne a sanya na'urar auna nauyi a wurin aunawa domin guje wa girgizar da ka iya shafar sakamakon.
3. Ma'auni Mai Maimaitawa: Don ƙara daidaito, ana ɗaukar ma'auni sau da yawa kuma ana amfani da matsakaicin sakamako azaman ƙimar nauyi a wannan lokacin.
Gyaran Aunawa
Da zarar an sami bayanai na gravimetric, ana buƙatar yin gyare-gyare da dama don samun bayanai masu inganci da inganci. Waɗannan gyare-gyaren sun haɗa da gyaran tida, gyaran yanayin ƙasa, gyaran Bouguer, da sauran ƙarin gyare-gyare da dama.
1. Gyaran Ruwa: Fannin nauyi na duniya yana shafar tasirin jan nauyi na wata da rana, wanda ke haifar da bambance-bambance na ɗan lokaci a ma'aunin nauyi. Dole ne a yi amfani da wannan gyaran nauyi na ruwa don samun ainihin ƙimar nauyi.

Taswirar Bayanai da Dabaru na Gabatarwa na Gravimetric
Taswirar bayanai da kuma nuna bayanai masu girman gaske muhimmin mataki ne a fannin sarrafa bayanai. Dabaru da aka fi amfani da su wajen tsara taswirar sun hada da:
1. Taswirar Contour: Contours, ko isolines, layuka ne da ke haɗa wurare masu darajar nauyi iri ɗaya. Waɗannan contours suna taimakawa wajen gano tsarin ƙasa da rashin daidaituwar nauyi.
2. Taswirar Launi: Sau da yawa ana gabatar da bayanan gravimetric a matsayin taswirar launi wanda ke nuna bambance-bambancen nauyi. Launuka daban-daban suna taimakawa wajen gano yankunan da ke da manyan bambance-bambancen nauyi.
3. Bayanin Girman Nauyi: Bayanin Girman Nauyi wani jadawali ne da ke nuna bambancin nauyi a kan wani layi da aka bayar. Wannan bayanin zai iya taimakawa wajen fahimtar bambancin nauyi a wani takamaiman alkibla.
Baya ga dabarun taswira na asali, ana amfani da fasahohin zamani kamar jujjuya bayanai da kuma yin samfurin siffofi uku don samar da cikakkun bayanai game da ƙasan Duniya.
