Fufuzani zithunzi za satana ndikufufuziridwa pogwiritsa ntchito Landviewer

Pofika pa kufufuza deta yeniyeni (AOI - Chigawo cha chidwi) kuti mudziwe zambiri kuchokera kumadera akutali, EOS - Earth Observing System ndi imodzi mwa nsanamira zogwiritsidwa ntchito kwambiri pa webusaiti; zonse zofufuzira, kusankha ndi kuwongolera mafano kuchokera pa nsanja za satana. Chipulatifomuchi chatsopano posintha zipangizo zazitali zadothi, zomwe ndi zoyenera kuyankhula.

Waukulu mawonekedwe Landviewer imakhala ya kumanzere mbali gulu, kumene zokolola za aliyense wa masensa danga ofotokoza zimene zokhudzana ndi AOI, ndi Toolbar pa gombe kumanzere, muli ntchito monga tikuonera: kujambula AOI (timagulu ting'onoting'ono, polygonal, kapena circular), muyeso, tawonani kuika, mndandanda wa zigawo, gawo, kusanthula nthawi ndi ma 3D. M'munsimu ndilo mlingo, malo ozungulira aderalo.

Poyambirira, mu bokosi la malo, malo amodzi adakondweretsedwa ndipo zithunzi zonse zokhudzana ndi mfundoyo zinasonyezedwa. Tsopano, pofufuza malo oyenera, AOI imangomangidwanso kamene imapereka mwayi wopezera laibulale yamagetsi. Kuwonjezera pa izi, ziyenera kuwerengedwa kuti musanayambe kuona, kufufuza, kusankha ndi kuwombola zochitika zilizonse, muyenera kulemba pa tsamba musanayambe ntchito iliyonse, kuyambira pamene mukulembetsani nthawi yoyezetsa masiku a 15 ndi omwe amapeza mapindu awa:

Kufufuza kosavuta, kusankhidwa kwakukulu, mapepala apakati ndi apamwamba, kusagwiritsidwa ntchito kosagwiritsidwa ntchito mosagwiritsidwa ntchito, kulengedwa kwa miyambo yowonjezera, kulumikizana kwa mbiri yakale, malo osiyanasiyana, ndi WMS kuti alowetse deta mu GIS iliyonse.

Nsanja -poyamba anali mfulu- Zili ndi phindu lalikulu komanso zatsopano. Poyamba mukhoza kumasula zosachepera za satellite za 10 pa tsamba lino, popanda chiletso; Tsopano, ndi zatsopano zosintha, ndizopadera kwambiri.

Akamaliza ntchito yomanga ya AOI, iwo amalowa anapereka zithunzi onse obwera ndi malowa. The pane lamanzere amasonyeza nsanja onse okhala deta malo amene kenako akhoza osasankhidwa malingana ndi cholinga cha phunziroli. Satellite nsanja sipangakhalenso osankhidwa mankhwala ndi: apachipata-2L1C + 2A, Landsat 8 Oli + TIRs, Landsat 7 ETM +, Landsat 4-5 TM, CBERS-4 MUX, CBERS .4 WFI CBERS-4 PAN5, CBERS 4 -PAN10 ndi NAIP.

Ubwino wogwiritsira ntchito AOI ndi kuti nsanja siidzawonetsa zotsatira zomwe sizikugwirizana kapena zomwe sizikuphimba dera lomwe likukhudzidwa, zonse zomwe zasinthidwazo zimaperekedwa kotero kuti malo omwe ali ndi chidwi akuphimbidwa ndi satana mankhwala a chisankho chosankhidwa. Izi ndizofunikira kwambiri, popeza m'mabwalo ena a descraga monga USGS, kapena malo a Alaska SAR, amalola kupeza mfundo, koma samatsimikizira kuti mfundoyi ili ndi zochitika zonse. Izi zimathandiza kuchepetsa nthawi yogwiritsa ntchito ndikusankha mankhwala, ndipo wothandizira akhoza kuthera nthawi yochulukirapo musanayambe kukonza kapena kupititsa patsogolo.

Mukamagwira ntchito ndi AOI, simudzapatsidwa kapena kusonyeza zithunzi zosasintha zomwe sizikugwirizana kapena makamaka kuphimba dera limene lasankhidwa.

Mitundu ina ya mafayilo angagwiritsidwe ntchito monga magwero a zithunzi, ndiko kuti, ngati ali masewero ausiku, masewera osakanikirana, masensa othamanga, deta yamtunda, deta ya EOS, ndi mafano otchuka. . Chimodzi mwa zosinthika za tsamba losangalatsa kwambiri ndi chakuti amathandiza wofufuza kuti adziwe kuti ndi masiku ati omwe ali ndi zinthu zokhudzana ndi AOI yawo, yomwe idalipo nthawi yoyamba ndi yomalizira yomwe inayikidwa ndipo zithunzi zonse zofananazo zinawonetsedwa.

Mukamalemba pa kalendala, mukhoza kuona masiku omwe akuwonetsedwa mu buluu, zomwe zimachitika pamene pali masewero, ndipo simukusowa kufufuza masiku ena, koma ndi zizindikiro za buluu, mungatsimikize kuti ndi masiku ati omwe ali ndi zisudzo.

Popeza nsanjayi ili ndi zithunzi zojambula bwino ndipo izi zimagwirizana kwambiri ndi zinthu zakuthambo monga cloudiness, palinso fyuluta yomwe imathandiza kutaya zithunzi zomwe zili ndi kuchuluka kwamtundu. Kuwonjezera pamenepo, n'zotheka kulembetsa kuti adzalandire zidziwitso za zatsopano zokhudzana ndi AOI, kapena ngati kufufuza kwina kulikonse kunapangidwa, dongosolo kapena kukumbukira ndi kutumiza zidziwitso za kupezeka kwa mankhwala.

ntchito amapulumutsa onse AOI, zinalengedwa, pa nthawi, akhoza dawunilodi ndi zipangizo zina zomwe anawonjezera pochotsa AOI kuumba mtundu kapena kuchotsedwa mogwirizana. Pogwiritsira ntchito ndondomeko, musanayambe kuona maonekedwewo, ndizolembedwa ndi NDVI kapena NDWI, panopa mwawonjezera zina zambiri, monga SAVI, ARVI, EVI, SIPI kapena GCI Grassland Clorophile Index.

Wogwiritsa ntchito, malingana ndi cholinga cha phunzirolo, akhoza kusintha zizindikirozo, kuika dzina limene iye akulingalira, sankhani pele yomwe imayimira kwambiri pophunzira -kapena kulenga chatsopano-, apeza malo ambiri, kuphatikizapo wogwiritsa ntchitoyo m'njira yosavuta.

Chinthu chinanso chochititsa chidwi ndi kusanthula, komwe kumakupangitsani kusunga nthawi yomwe kale munali zojambula, ndipo mukhoza kuona momwe AOI yomwe yasankhidwa kale idasinthika. Mukhoza kupanga zithunzi zofanana pakati pa zojambulazo, kapena ndemanga zomwe pulatifomu imapereka. Mzerewu ukhoza kuchoka ku 1 kufika ku 6 miyezi, kapena kuchokera chaka cha 1 kufikira zaka 10, ngati nthawi yeniyeni ikufunika, ikhozanso kuikidwa.

Mu siteji yatsopanoyi ya Landviewer, n'zotheka kuwonetsa zithunzizo, chifukwa zimadziwika kuti chifukwa cha mlengalenga kapena zinthu zina zingakhale zomveka bwino kapena zakuda, zomwe zowonjezera zowonjezera zakhala zikuwonjezeredwa. kutambasula, kulingalira za histogram, muzithunzi za mdima kapena kuunika kwakukulu komwe malowa ali nawo.

Pali 4 zomwe mungasinthe posintha chithunzi:

  • Kutambasulira histogram yapafupi,
  • kutambasula histogram yathunthu data,
  • gawo lachigawo la kuchepetsa kudulidwa,
  • Chomera chocheka chotsalira (chosasintha).

Kuwonjezera pamwambapa, mukhoza:

  • Inu kuwonjezera zigawo kuona kupyolera maseva WMS, zithunzi akhoza dawunilodi ndi kudula AOI, kotero ili ndi mubokosi losakira (1) kapena wathunthu miyezo m'dera mankhwala ndi mwachilungamo wophweka, mungathe Pezani mndandanda wa zigawo zomwe zinagwiritsidwa ntchito popita ku nsanja (kuchokera pa mapu ozungulira, kudutsa dziko la MDT, mpaka kuchithunzi chomaliza).
  • Amanena kuti angathe kutenga nawo mbali pa malo ochezera a pa Intaneti, monga pa Twitter, LinkedIn, Facebook, kapena kudzera mu link (2). Mofananamo, ngati pali vuto lililonse papulatifomu, gulu lothandizira limalowetsedwa mu batani omwe amapezeka kumunsi kumanzere kwa chinsalu (3).

Ndikofunika kuwona momwe zipangizo monga izi, zithandizira kukonza ndikuwongolera kukonza deta, komanso kumanga kusanthula malo. Makina awa amachokera pa deta mumtambo, mukhoza kusunga mtambo wa EOS katundu wochuluka ndikuwulandira kuchokera pamakompyuta aliwonse, chinthu chokha chimene chiyenera kuwerengedwa ndikuti sichilinso malo opanda ufulu, ndi ofunikira ofunika kulipira pazinthu zoperekedwa. Tidzawona posachedwa ngati zipangizozi, pang'onopang'ono kapena m'malo mwazitsulo za GIS ndi PDI (Digital Image Processing), zomwe zagwiritsidwa ntchito masiku ano monga ERDAS Imagine kapena ENVI.

Kulowa, kulembetsa ndi kupeza masiku oyesa a 15, pita kuzilumikizano zotsatirazi: Landviewer-EOS.
