GIS yodabwitsa, chinthu china ndi zigawo

Kanthawi kapitako Ndayankhula m'nkhani momwe kusindikiza kufotokozera kumagwiritsidwa ntchito zobwezedwa GIS. Panthawi imeneyo tinapanga chithunzi chabwino kwambiri, panopa ndikufuna kuwonetsa chimodzi chovuta. Ichi ndi chitsanzo cha mapu a zokolola zamagetsi; monga mapu aakulu ndi ntchito yomwe ikugwiritsidwa ntchito kuchokera ku fano la satanala, pansi pake ili ndi mapu amphamvu a mapu a Simmons Map komanso kugwiritsa ntchito FAO.

Chithunzi 3132 Mmene mungachitire IMS ndi GIS yochulukaChoyamba, ndikofunikira kumvetsetsa kapangidwe ka zinthu zomwe ntchito zamagetsi, monga momwe ndalongosolera Nkhani yapitayi, popeza zinthu zomwezo zimasungidwa mu dongosolo malinga ndi ntchito.

Chithunzi

Izi ndizomwe zimapangidwira, zomwe zili mu Manifold sizitsimikizirika, zingakhale ndi maonekedwe osokonezeka, mizere kapena madontho, popeza zonse zili mu deta yachinsinsi. Chithunzichi chingakhale ndi ana, zizindikiro zina monga:

  • Gome, lomwe liri mawonedwe owonetsera. Izi ndizosiyana pojambula.
  • Malemba, omwe ndi malembo amphamvu a munda womwe wasonyezedwa pamapu. Mukhoza kulumikiza malemba ambiri monga momwe mukufunira, iwo ali ndi chithunzi mujambula ndipo angasunthikenso.
  • Mitu, izi zomwe sindinayambe zanenedwa, koma ndizoyimira zowonongeka, zikhoza kukhala zingapo ndipo zimakhalanso ndi mapu ku mapu.

Mapu

Ndilo lingaliro la zigawo. Izi zili ndi zida zosiyanasiyana, malemba, raster. Zitha kukhala zojambula mwachindunji koma sizikulimbikitsidwa pamene zidzasintha pamene zijambula pa mutu wina, chifukwa mumakonda kutchula mitu. Mumasankha zomwe zikukwera mmwamba, zomwe zimawonekera bwino, ndi mitundu yanji ya mndandanda, mzere, makulidwe, chiwembu ... panthawi yathu.

Onani chitsanzo mu chithunzi choyambirira. Ndi momwe mapu omwe akuyang'ana omwe akuwonetsedwa pa mapu oyambirira akulengedwa. Ikusonyeza momwe malemba, tebulo ndi mutu wa mapu a ntchito ya FAO ndi zinyama, ndipo izi zimasungidwa pa mtundu wa mapu.

Makhalidwe

Ndilo kusindikizira kwa kusindikiza ndi kutsekedwa kumapu. Mukhoza kukhala ndi ambiri omwe akufunikira, ndipo mukhoza kukhala odziimira.

Pamene mukuwona, zizindikiro zotsatirazi zikufotokozedwa, zomwe zikufanana ndi zomwe zimachitika ndi Arcmap, zoyambazo ndizogwirizana ndi malo olembera mabokosi. Ndiye pali njira zomwe mungapangire zowonongeka, mizere yowongoka, tebulo, malo apakati kuchokera pakati, ndime, nthano, chizindikiro chakumpoto ndi bar. Iwo samawonetsedwa mu bar koma palinso malamulo kuti agwirizane ndikugawira. Iwo amanyamula Zida> kusintha> kugwirizana.

Chitsanzo chotsatira chikuwonetsa nkhani ya nthano, izi zikhoza kusungidwa payekha kapena mkati mwa deta. Kuwonjezera apo, ndawonjezera mzere wogawikana koma mungathe kuwonjezera zowonjezera zomwe mungapange nthano kudutsa.

Choncho ngakhale kuti Zovundikira sizibweretsa antchito osawuka, ntchito yaikulu ndi kuika mapu pamodzi, ndiye amangoyenda pa tsamba ndikusintha kukoma kwake. M'zinthu (ndi chophindikiza kawiri) mungasankhe ngati mukufuna kukhala ndi gridi pamtunda, ngati mukufuna kuti ikhale malo ozungulira kapena osonyezera UTM. Komanso kukula, chizindikiro ndi kumpoto.

Kuonjezerapo mungathe kujambula zithunzi monga momwe ndagwirira ndi chishango cha ngodya komanso Maofesi ogwirizana a Excel monga momwe ndachitira ndi bokosi la buluu pansi.

Kotero, mwachidule, pulojekiti yomweyi imathandizira mipangidwe yambiri, yomwe ili ndi mapu, izi ndi mitu ndi zochitikazo ndizoimira zigawo za vector.

Ndiponso ma bokosi olemba akhoza kukhala ndi macros, monga momwe asonyezedwera pa chithunzichi, pamene dzina, ndondomeko, tsiku kapena polojekiti ikuthandizira.

Ndipo ndithudi, kamodzi kamapanga mapu akhoza kuphatikiza kuti apange china, kusinthira mafayilo opangira mafomu popanda kumanga template kuyambira pachiyambi.

Kuti muzitumize izo, dinani pomwepo pazomwe mumasankha ndikusankha ngati mukufuna kusindikiza, sungani monga pdf ndi zigawo kapena ngati chithunzi chokweza kwambiri. Ikhozanso kukhala mu format ya .ai ya Adobe Illustrator.


Pomalizira, ndiwamphamvu kwambiri. Ngakhale zimatenga nthawi kuti mumvetse mfundo zake.
