Qee qhov kev txwv tseem ceeb ntawm Lambert Conformal conic projection yog: Rhumb kab yog cov kab nkhaus uas tsis tuaj yeem npaj tau raug. Qhov siab tshaj plaws nce raws li qhov dav latitudinal nce. Parallels yog cov kab nkhaus (arcs ntawm concentric voj voog).
kab rhumb ntawm Mercator projection yog dab tsi?
Rhumb kab yog kab ntawm kev coj tus kheej tsis tu ncua. Lawv nkhaus nyob rau hauv lub ntiaj teb tab sis cov kab ncaj nraim ntawm Mercator's Map. Daim ntawv no tshawb xyuas yuav ua li cas los tsim Mercator's Map los ntawm qhov projecting cov kab nkhaus ntawm 3-dimensional Earth raws li cov kab ncaj nraim hauv 2-dimensions.
Qhov twg ntawm daim duab Lambert yog qhov tseeb?
Lub Lambert's Conformal Chart tsis siv ib qho Standard Parallel, tab sis ob. Tus Txheej Txheem Parallels raug faib los ntawm qhov nruab nrab ntawm qhov sib luag - Parallel ntawm Keeb Kwm. Qhov ntsuas: Yog raug ntawm tus qauv Parallels.
Dab tsi yog qhov zoo ntawm Lambert Conformal Conic projection chart?
Lambert conformal conic yog ib qho kev kwv yees conic. Tag nrho cov meridians sib npaug sib npaug ntawm cov kab ncaj nraim converging rau ib qho taw tes, uas yog tus ncej ze tshaj plaws rau tus qauv parallels. Cov parallels yog sawv cev raws li lub voj voog arcs nyob nruab nrab ntawm tus ncej. Lawv qhov sib nrug nce deb ntawm cov qauv sib luag.
kab rhumb ntawm daim duab yog dab tsi?
Ib kab rhumb tshwm li ib txoj kab ncaj nraim ntawm Mercator projection map. Lub npe yogmuab los ntawm Old French los yog Spanish feem: "rumb" los yog "rumbo", ib kab ntawm daim ntawv uas cuam tshuam tag nrho cov meridians ntawm tib lub kaum sab xis. Ntawm lub dav hlau saum npoo qhov no yuav yog qhov luv tshaj ntawm ob lub ntsiab lus.
