Hauv GIS , topology tau raug txhais ua "thescience thiab lej kev sib raug zoo siv los. validate entitiesvector geometry thiab ib tug series ntawm kev khiav hauj lwm xws li network analysisand. neighbourhood" [2]. Topology cov ntsiab lus ua rau spatialanalysis xws li tsis tuaj yeem txiav txim siab yam khoom dab tsi.

Ntawm no, dab tsi yog txhais los ntawm topology hauv GIS?

A GIS topology yog ib txheej ntawm cov kev cai thiab kev coj cwj pwm ua qauv li cas cov ntsiab lus, kab, thiab polygons sib koom coincidentgeometry. Piv txwv li: Cov yam ntxwv uas nyob ib sab, xws li ob lub nroog, yuav muaj ib thaj tsam ntawm lawv. Lawv sib koom cov ntug no.

Kuj Paub, vim li cas lub topology tseem ceeb? Qhov tseem ceeb ntawm network topology Ua si a tseem ceeb lub luag haujlwm hauv kev ua haujlwm ntawm network. Pab txo cov nqi khiav lag luam thiab kev saib xyuas xws li cov nqi cable. Ib lub network topology yog ib qho tseem ceeb ntawm kev txiav txim siab hom xov xwm siv los txuas rau lub network. Kev ua yuam kev orfault nrhiav tau yooj yim siv network topologies.

Ib yam li ntawd, koj tuaj yeem nug, cov cai topology yog dab tsi?

Topology cov cai tso cai rau koj los txhais cov kev sib raug zoo ntawm cov nta hauv ib chav kawm tshwj xeeb lossis subtypeor ntawm ob chav kawm tshwj xeeb lossis subtypes. Topology cov cai tso cai rau koj los txhais cov kev sib raug zoo spatial uas ua tau raws li qhov xav tau ntawm koj cov qauv ntaub ntawv.

Dab tsi yog topological kev sib raug zoo?

Kev sib txuas piav qhia txog txoj kab txuas rau ib leeg los tsim ib lub network. Adjacency piav qhia seb ob thaj chaw nyob ib sab ntawm ib leeg, thiab cov ntaub thaiv npog piav qhia seb ob thaj chaw puas nyob. Pab muab topological kev sib raug zoo , peb imposea txwv txoj kab uas yog kom tsis txhob hla ib leeg.
