Ua li no, qhov sib npaug sib npaug li cas?

Sib npaug Interval kev faib tawm. Hauv Sib npaug Interval Classification txhua chav kawm occupies ib sib npaug sib npaug raws tus lej kab. Lawv pom los ntawm kev txiav txim siab qhov ntau ntawm cov ntaub ntawv. Qhov ntau yog muab faib los ntawm cov chav kawm, uas muab qhov sib txawv.

Tsis tas li ntawd, hom kev faib cov ntaub ntawv twg rhuav tshem cov ntaub ntawv mus rau hauv cov chav sib npaug ntawm cov kev soj ntsuam? Qhov quantile. kev faib tawm txoj kev chaw sib npaug tus lej ntawm kev soj ntsuam hauv txhua chav kawm . Txoj kev no yog qhov zoo tshaj plaws rau cov ntaub ntawv uas yog sib npaug faib thoob plaws nws qhov ntau.

Kuj Paub, dab tsi yog quantile classification hauv GIS?

Quantile classification yog data kev faib tawm txoj kev uas faib ib pawg ntawm qhov tseem ceeb rau hauv pab pawg uas muaj qhov sib npaug ntawm tus nqi. Tus cwj pwm tseem ceeb tau ntxiv, tom qab ntawd muab faib rau hauv cov chav kawm ua ntej. Daim duab qhia 10 cov ntsiab lus hauv txhua lub sijhawm, uas ua rau cov ntu sib txawv tsis sib xws.

Puas yog hnub nyoog yog qhov sib npaug ntawm qhov sib txawv?

Ib qho piv txwv: Hnub nyoog Ib qho piv txwv zoo ntawm qhov no yog a sib txawv nyiam hnub nyoog . Hnub nyoog yog, technically, nruam thiab piv. Ib tus neeg hnub nyoog puas, tom qab tag nrho, muaj lub ntsiab lus xoom point (yug) thiab txuas ntxiv yog tias koj ntsuas nws qhov tseeb txaus.
