LandViewer - Sinthani kuzindikira tsopano ikugwira ntchito mu msakatuli
Kugwiritsa ntchito kofunika kwambiri kwa deta zakutali kwakhala kuyerekezera mafano kuchokera kudera linalake, kutengedwa nthawi zosiyanasiyana kuti adziwe kusintha komwe kunachitika pano. Pokhala ndi zithunzi zambiri za satelanti zomwe zikugwiritsidwa ntchito poyera, patapita nthawi yaitali, kufufuza mwatsatanetsatane ka kusintha kungatenge nthawi yaitali ndipo mwinamwake kungakhale kosavomerezeka. EOS Data Analytics yakhazikitsa automated tool of kuzindikira kwa kusintha mu malo ake ogulitsa malo, LandViewer, yomwe ili pakati pa zipangizo zamatabwa zogwiritsira ntchito zamtundu wa kufufuza ndi kusanthula zithunzi za satana pamsika wamakono.
Mosiyana ndi njira zomwe zimaphatikizapo mautumiki a neural omwe dziwani kusintha mu zikhalidwe zomwe zinatengedwa kale, kusintha kwa kusintha kwasinthidwe kochitidwa ndi mbo USA njira yamapikiselini, yomwe imatanthauza kuti kusintha pakati pa mafano awiri a mulband pamasomali kumawerengedwa masamu pamtanda pochotsa malingaliro a pixel a tsiku limodzi ndi miyeso ya pixel ya zofanana za tsiku lina. Chizindikiro chatsopano chatsopanochi chakonzedwa kuti chidziwitse kusintha ndikupereka zotsatira zolondola ndi zochepa zochepa komanso panthawi yochepa poyerekeza ndi ArcGIS, QGIS kapena mapulogalamu ena opangira zithunzi za GIS.
Kusintha kwa mawonekedwe kusintha. Zithunzi za m'mphepete mwa nyanja ya Beirut zimasankhidwa kuti zidziwe zomwe zachitika posachedwapa.
Kuzindikira kusintha kwa mzinda wa Beirut
Kulimbana kwakukulu kwa ntchito: kuchokera ku ulimi mpaka kuwonetsetsa zachilengedwe.
Chimodzi mwazolinga zoyikidwiratu ndi gulu la EOS chinali kupanga njira zosinthira zovuta kuti anthu azitha kudziwa zambiri zakutali ndikosavuta kwa ogwiritsa ntchito osazindikira a mafakitale omwe si a GIS. Ndi chida chodziwira kusintha kwa LandViewer, alimi amatha kuzindikira msanga malo omwe awonongeka m'minda yawo ndi matalala, namondwe kapena kusefukira kwamadzi. Poyang'anira nkhalango, kuzindikira kwa kusintha Pachithunzi cha satelayiti, chikhala chothandiza kuwerengera madera omwe awotchedwa, moto udawotcha ndikuwunika kudula mitengo mosaloledwa kapena kuwukira nkhalango. Kuwona kuchuluka kwa kusintha kwa nyengo (monga kusungunuka kwa madzi oundana, madzi ndi kuwonongeka kwa madzi, kuwonongeka kwa malo okhala chifukwa chakuchuluka kwamatawuni) ndi ntchito yopitilira ndi asayansi yachilengedwe, ndipo tsopano angathe. mu mphindi zochepa. Pofufuza kusiyana pakati pa zakale ndi zam'mbuyomu pogwiritsa ntchito zaka zambiri za satellite ndi chida chodziwitsira kusintha kwa LandViewer, mafakitale onsewa amathanso kulosera zamtsogolo.
Zomwe zimagwiritsidwa ntchito pozindikira kusintha: kusefukira kwa madzi ndi kusefukira kwa mitengo
Chithunzi chili ndi mawu chikwi, komanso kusintha kwasintha kwa zithunzi za satellita LandViewer Zikhoza kuwonetsedwa bwino ndi zitsanzo zenizeni zamoyo.
Nkhalango akadali kuphimba za lachitatu m'dera lonse ali anazimiririka modetsa nkhawa, makamaka chifukwa zochita za anthu monga ulimi, migodi, odyetserako ziweto, kudula mitengo ndi zinthu zachilengedwe monga moto wa m'nkhalango. M'malo akuchita maphunziro akuluakulu dziko la zikwi maekala ya m'nkhalango, ndi katswiri nkhalango nthawi zonse kuwunika chitetezo cha nkhalango ndi awiri zithunzi Kanema ndi kudziwika kusintha basi zochokera NDVI (Zomera Index dekhetsa Kusiyana) .
Zimagwira bwanji? NDVI njira yodziwika yodziwitsa thanzi la zomera. Poyerekeza chithunzi cha satellite cha nkhalango yosasunthika, ndi chithunzi chomwe chidapezeka mitengo itangodulidwa, LandViewer ipeza zosinthazo ndikupanga chithunzi chosiyanitsa mitengo yomwe ikudulidwa, ogwiritsa ntchito akhoza kutsitsa zotsatira mu .jpg, .png kapena .tiff mtundu. Chophimba m'nkhalango chomwe chimapulumuka chidzakhala ndi zabwino, pomwe madera omwe achotsedwa amakhala ndi zoyipa ndipo adzawonetsedwa m'mawu ofiira osonyeza kuti kulibe zomera.
Chifaniziro chosiyana chosonyeza kukula kwa mitengo ku Madagascar pakati pa 2016 ndi 2018; yopangidwa kuchokera ku zithunzi ziwiri za satellite za Sentinel-2
Mlandu wina wogwiritsidwa ntchito pofufuza zosintha ukakhala kuwunika kwa kusefukira kwaulimi, komwe kuli kosangalatsa kwa alimi ndi makampani a inshuwaransi. Nthawi zonse kusefukira kwamadzi kukakolola kwambiri pa zokolola zanu, kuwonongeka kumatha kupangidwanso mwachangu ndikuyesedwa mothandizidwa ndi NDVI-based based algorithmms detection algorithm.
Zotsatira za malo a Sentinel-2 zimasintha: malo ofiira ndi alanje amaimira gawo lamtunda; Masamba oyandikana nawo ndi ofiira, omwe amatanthauza kupeŵa kuwonongeka. Chigumula cha California, February wa 2017.
Momwe mungapangire kuyang'ana kusintha mu LandViewer
Pali njira ziwiri zoyambira chida ndikuyamba kupeza kusiyana kwa zithunzi za satellite zanthawi yayitali: podina chizindikiro cha "Analysis Tools" kumanja kapena Comparison slider, chilichonse chomwe chili chosavuta. Pakali pano, kusintha kusintha kumachitika kokha pa optical (passive) satellite data; kuwonjezeredwa kwa ma aligorivimu a data yogwira zowonera kutali kumakonzedwa kuti zisinthidwe mtsogolo.
Kuti mudziwe zambiri, werengani buku ili chosintha chogwiritsira ntchito kuchokera ku LandViewer. KAPENA Yambani kufufuza zomwe zingatheke posachedwapa LandViewer pawekha
