Geographic Information System ( GIS ) yog lub tshuab computer rau kev ntes, khaws cia, kuaj xyuas, thiab nthuav tawm cov ntaub ntawv ntsig txog cov haujlwm ntawm lub ntiaj teb nto. Los ntawm kev txheeb xyuas cov ntaub ntawv zoo li tsis muaj feem cuam tshuam, GIS tuaj yeem pab tib neeg thiab cov koom haum kom nkag siab txog cov qauv thiab kev sib raug zoo.
Ib yam li ntawd, GIS yog dab tsi thiab nws hom? GIS cov ntaub ntawv tuaj yeem muab cais ua ob pawg :spatially referenced cov ntaub ntawv uas yog sawv cev los ntawm vector thiab rasterforms (nrog rau imagery) thiab attribute tables uas yog sawv cev rau hauv tabular hom.
Ib yam li ib tug yuav nug, GIS Support yog dab tsi?
Geographic Information System ( GIS ) yog lub tshuab computer tsim los ntes, khaws cia, tswj xyuas, txheeb xyuas, tswj thiab nthuav tawm txhua yam ntawm cov ntaub ntawv spatial lossis thaj chaw. Qhov no yog ua tiav siv cov lus nug builder tool. Tom ntej no tseem ceeb nta ntawm lub GIS yog lub peev xwm los muab cov txheej txheem sib txawv los qhia cov ntaub ntawv tshiab.
Vim li cas peb thiaj xav tau GIS?
Yooj yim muab, a GIS (Geographic Information System) sib txuas cov txheej txheem ntawm cov ntaub ntawv hais txog qhov chaw kom nkag siab zoo dua ntawm qhov chaw. GIS txuas maps rau databases thiab tsim avisualization ntawm cov ntaub ntawv, thiab tso cai interactivity ntawm daim ntawv qhia thiab cov ntaub ntawv nyob rau hauv ib tug database.

Koj txhais qhov hnyav txhais li cas?
Cov ntsiab lus. Weighted Mean: Ib qho txhais tau tias qee qhov txiaj ntsig pab ntau dua li lwm tus. Thaum qhov hnyav ntxiv rau 1: tsuas yog muab txhua qhov hnyav los ntawm tus nqi sib xws thiab suav tag nrho. Txwv tsis pub, muab txhua qhov hnyav w los ntawm nws qhov sib piv tus nqi x, suav tias tag nrho, thiab faib los ntawm qhov sib npaug ntawm qhov hnyav: Qhov Ntsuas Ntsuas = ΣwxΣw
Cov ntsiab lus hydrophilic thiab hydrophobic txhais li cas thiab lawv cuam tshuam li cas?
Hydrophobic txhais tau hais tias cov molecule yog "ntshai" dej. Cov tails ntawm phospholipid yog hydrophobic, txhais tau tias lawv nyob hauv daim nyias nyias. Hydrophilic txhais tau hais tias cov molecule muaj affinity rau dej
Vim li cas nws tseem ceeb kom paub tias koj txhais li cas ntxiv?
Txhais qhov seem. Kev txhais cov lus tseem ceeb yog qhov tseem ceeb thaum koj faib ua lej vim tias koj tuaj yeem tau txais qhov teeb meem tsis raug yog tias koj tsis txhais cov seem kom raug.

Txhawm rau txhais cov ntsiab lus P (x, y), ib chav nyob sab xis thiab b units, siv P'(x + a, y + b)
