Qhov tsis zoo / Cov kev txwv ntawm kev hnov mob nyob deb :
Kev paub txog tej thaj chaw deb yog kim thiab tsis raug nqi rau kev sau cov ntsiab lus rau ib cheeb tsam me me. Kev sau cov ntaub ntawv rau cheeb tsam hauv cheeb tsam, kev cob qhia tshwj xeeb, khoom siv thiab kev saib xyuas yuav raug nqi rau ib cheeb tsam me me piv nrog cov cheeb tsam loj
Ntxiv mus, dab tsi yog qhov tsis zoo ntawm kev paub txog tej thaj chaw deb?
Disadvantages ntawm remote sensing:
- Kev paub txog tej thaj chaw deb yog ib txoj hauv kev uas kim heev ntawm kev tsom xam tshwj xeeb tshaj yog thaum ntsuas lossis txheeb xyuas qhov chaw me me.
- Kev paub txog tej thaj chaw deb yuav tsum muaj kev cob qhia tshwj xeeb los txheeb xyuas cov duab.
- Nws yog qhov kim los txheeb xyuas cov duab rov qab yog tias yuav tsum tau txheeb xyuas qhov sib txawv ntawm cov duab thaij duab.
Tsis tas li ntawd, kev siv cov chaw taws teeb sensing yog dab tsi? Kev paub txog tej thaj chaw deb yog tus txheej txheem ntawm kev kuaj xyuas thiab saib xyuas cov yam ntxwv ntawm lub cev ntawm ib cheeb tsam los ntawm kev ntsuas nws qhov cuam tshuam thiab tawm hluav taws xob ntawm qhov deb (feem ntau los ntawm satellite lossis dav hlau). Cov koob yees duab tshwj xeeb sau nyob deb tau hnov cov duab, uas pab cov kws tshawb fawb "xav" yam txog lub ntiaj teb.
Hais txog qhov no, cov kev txwv ntawm GIS yog dab tsi?
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov nyob rau theem pib tias tseem muaj mob hnyav txwv rau GIS . Cov no poob rau hauv plaub chav kawm tseem ceeb: teeb meem ua nrog rau GIS cov ntaub ntawv qauv; teeb meem ua nrog cov ntaub ntawv lawv tus kheej; teeb meem nrog kev kawm paradigm; thiab cov teeb meem siv tau.
Dab tsi yog hom kev paub txog tej thaj chaw deb?
Muaj ob hom kev paub txog tej thaj chaw deb technology, active thiab passive kev paub txog tej thaj chaw deb . Active sensors emit zog nyob rau hauv thiaj li yuav luam theej duab cov khoom thiab cov cheeb tsam whereupon a sensor tom qab ntawd kuaj thiab ntsuas cov hluav taws xob uas cuam tshuam los yog rov qab los ntawm lub hom phiaj.

Lub teeb sib tham txog tej yam ntuj tso thiab manmade qhov chaw ntawm lub teeb yog dab tsi?
Tej qhov chaw ntawm lub teeb muaj xws li lub hnub, hnub qub, hluav taws, thiab hluav taws xob nyob rau hauv cua daj cua dub. Tseem muaj qee cov tsiaj thiab nroj tsuag uas tuaj yeem tsim lawv tus kheej lub teeb, xws li fireflies, jellyfish, thiab nceb. Qhov no hu ua bioluminescence. Artificial light yog tsim los ntawm tib neeg
Dab tsi yog qhov loj wavelength ranges siv rau tej thaj chaw deb sensing?
Optical tej thaj chaw deb sensing pab kiag li lawm ua hauj lwm nyob rau hauv lub pom, nyob ze infrared, nruab nrab infrared thiab luv yoj infrared ib feem ntawm lub electromagnetic spectrum. Cov khoom siv no muaj kev nkag siab rau lub wavelengths xws li 300nm txog 3000nm
Dab tsi yog qhov kev hloov pauv ntawm cov khoom uas txav ntawm qhov chaw mus rau qhov chaw ntawm - 12 m?
Kev piav qhia: Qhov kev txav ntawm ib qho khoom txav ntawm qhov chaw mus rau qhov chaw ntawm − 12 m yog 12 meters. Qhov kev ncua deb ntawm lub hauv paus chiv keeb mus rau qhov siab tshaj plaws txoj hauj lwm yog hu ua displacement ntawm ib yam khoom. Qhov siab tshaj plaws kev hloov pauv ntawm cov khoom nyob rau hauv ib nthwv dej yog hu ua crest thiab qhov tsawg kawg nkaus hloov pauv yog hu ua trough
Daim ntawv qhia dab tsi qhia txog qhov chaw ntawm thaj chaw?
Ntiaj Teb Kev Tshawb Fawb - Daim Ntawv Qhia Lub Ntiaj Teb Qhov Nto A B TOPOGRAPHIC MAP Daim duab qhia chaw uas qhia txog cov yam ntxwv ntawm thaj chaw. CONTOUR LINE Ib kab ntawm daim ntawv qhia saum toj kawg nkaus uas txuas cov ntsiab lus ntawm qhov siab sib npaug. CONTOUR INTERVAL Qhov txawv ntawm qhov nce ntawm ib kab contour mus rau lwm qhov
Electron tej thaj chaw deb yog dab tsi?
Cov chaw taws teeb module muab txoj hauv kev yooj yim los ua kev sib txuas lus sib txuas (IPC) ntawm cov txheej txheem renderer (web page) thiab cov txheej txheem tseem ceeb. Hauv Electron, GUI-txog modules (xws li kev sib tham, ntawv qhia zaub mov thiab lwm yam) tsuas yog muaj nyob rau hauv cov txheej txheem tseem ceeb, tsis yog nyob rau hauv cov txheej txheem renderer
