Hoton hotunan zai iya zama da amfani sosai a gare mu muyi amfani da shirin CAD / GIS amma idan muna so mu kira shi zuwa Google Earth baza'a iya kawo shi ba sai dai idan muka fitar da ita zuwa Global Mapper zuwa masaurar da ke dauke da hoton.

4. Fitar da hoto zuwa kmz

Kullum mun fahimta ta hanyar kilomita wanda ya ƙunshi wasu layi, maki ko polygons, yana yin la'akari da kb kawai.

Idan ana fitar da shi zuwa kmz shirin zai fara yin amfani da nau'i-nau'i iri-iri da aka fara hotunan a cikin sassan kuma yana sanya takaddama a cikin kilomita, kamar haka lokacin da aka bude kmz a cikin Google Earth abin da ya kawo shi ne hoton.

Domin ganin abin da ke cikin kmz, sai a canza wajan tsarin da aka matsa .rar / .zip sannan a zazzage shi cikin babban fayil. A can zaka ga cewa akwai fayil da ake kira doc.kml wanda ya ƙunshi nau'ikan abubuwa a cikin tsarin sa yankin kuma tare da hoton da ake kira as landoverlay.
