Palibenso malo akhungu omwe ali ndi ntchito za Mose

Mosakayikira, mlandu wabwino kwambiri mukamagwira ntchito ndi zithunzi za satellite ndikuti mupeze zithunzi zoyenera kwambiri pazomwe mungagwiritse ntchito, titi, Sentinel-2 kapena Landsat-8, yomwe imaphimba madera anu okondweretsedwa (AOI); chifukwa chake, imalola kuti ipeze mwachangu komanso data yolondola chifukwa cha kukonzekera. 

Nthawi zina, magawo ena a AOI anu, makamaka muma AOI akulu omwe amaphimba zithunzi zingapo, komanso ma AOIs omwe ali pafupi kapena kumapeto kwa zifaniziro, akhoza kutsalira kupitirira malire a malo omwe alipo. Mavuto awa ophatikizira zithunzi zophatikizira amatha kubweretsa kusanthula pang'ono ndi kutaya chidziwitso chofunikira.

Mosaic adabadwa kuti athetse mavuto amgwirizano wazithunzi 

Mose adapangidwa kuyambira pachiwonetsero ngati chosavuta kugwiritsa ntchito chomwe chimakupatsani mwayi wophatikiza, kuphatikiza ndi kuwona zithunzi zomwe zidagawidwa kuchokera ku sensor, kukhala chithunzi, kwa AOI yeniyeni ndi nthawi yofunikira ya data.

Zojambula zonse zomwe zilipo patsiku lofunikalo zimaphatikizidwa ndipo AOI imaphimbidwa ku 100%.

Yankho lake ndi losavuta komanso lothandiza kotero kuti ndizodabwitsa kuti silinachitikepo kale.

Zoyambira za Mose zomwe zimapezeka mu zida za GIS

Pali njira zosiyanasiyana Kuti mupange lanu la Mose, mutha kusankha mwachangu zomwe ndizoyenera kwambiri pazosowa zanu.

• Zochitika padziko lonse za Mose

• Mose amaphatikizidwa kuchokera kuzidutsa zonse za satellite patsiku.

• Mose adapangidwa mosamalitsa m'dera lokhazikitsidwa ndi chidwi (AOI). 

Kodi Mose amagwira ntchito bwanji ku LandViewer?

LandViewer (LV), kenako, imapereka njira zingapo, ndiye kuti, wogwiritsa ntchito amakoka AOI. Kenako dongosololi limakulunga AOI mu bokosi lomwe limafotokozedwa mozungulira AOI, kutengera zithunzizo. Mwachitsanzo, ngati AOI ili yozungulira, zojambulazo zidzaimiridwa mkati mwa bwaloli.

Kutengera njira yomwe AOI imakhazikitsidwa, wogwiritsa ntchito apeza zotsatirazi:

• Mukaponya chikhomo pamapuwo, pulogalamuyo imapanga mndandanda wazomwe mungafufuze, monga momwe mudapangira kale. 
• Ngati mujambula AOI yayikulu kapena AOI yomwe ili m'mphepete mwa zithunzi ziwiri kapena zingapo, a Mose adzamalizidwa pazotsatira zakusaka

Mkhalidwe wokhawo wokhazikitsa lamulo la Mose ndi AOI

Mukatulutsa AOI yophimba mawonekedwe angapo, kusefedwa kwamtambo ndikukhazikitsa gawo lofunikira la dzuwa, kachitidweko kamawonetsa zotsatira zakusaka za Mose ndikuwonetsa mwachidule malinga ndi magawo omwe adakhazikitsidwa. Ziwerengero zamawu a Mose zimafotokozedwa pamakhadi akuwonetseratu.

Mphamvu zazikulu za Mose

Tafika pachinthu chofunikira kwambiri. Kodi tingatani ndi Mose? Tikaona Mose pamapupo, titha kupitilizabe kusankha izi:

Kugwiritsa Ntchito Msakatuli:

• Ikani ma index ndi kuphatikiza kwa magulu, onse osakwanira komanso mwambo.
• Khazikani zowala ndikusiyanitsa.

Kusanthula kwa asakatuli (kubwera posachedwa)

• Wunikirani ndikuwunika momwe malingaliro amalo ena asinthira pakati pa nthawi ziwiri kapena kupitilira ndi kusintha kwa ntchito.
• Imagwira bwino kasamalidwe ka zone molingana ndi mndandanda wamtengo wapatali, pogwiritsa ntchito ntchito ya Kusintha.

• Tsimikizani kukula kwamasamba kudera lomwe muli nalo chidwi (AOI) kwakanthawi ndizosankha za Time Series

• Pangani nkhani zowoneka bwino za GIF kapena kanema ndikugawana zambiri ndi ogwiritsa ntchito pa intaneti ndi makanema Nthawi yatha.

Tsitsani zosankha zomwe zikupezeka pa LandViewer 

Mitundu itatu yakutsitsa ikhoza kugwiritsidwa ntchito pa Mose, awa ndi Visual, Analytics kapena Index, kutengera zosowa za wogwiritsa ntchito.

Chidziwitso: wosuta amasankha mtundu wotsitsa "Mosaic" kapena "Zidutswa Zambiri". Kusiyanitsa pakati pa zosankha ziwirizi kuli mu data yomaliza yomwe idzaperekedwe kwa wogwiritsa ntchito: makina amatsitsa zithunzi zophatikizidwa ndi njira yotsitsa ya "Mosaic"; makina amatsitsa zidutswa zazithunzi ngati mndandanda ngati gawo la "Miss Fragments" lasankhidwa.

Zowoneka: mukasankha mtundu zithunzi, zomwe zikubwera zidzaperekedwa mu mafayilo a fayilo ya JPEG, KMZ ndi GeoTIFF yomwe ili ndi mawonekedwe osakanikirana (mwachitsanzo, zithunzi zonse zomwe zimagwera mu AOI ndipo osawoloka).

Zosintha: zotsatira za kutsitsa ndi Zosintha osankhidwa adzakhala fayilo ya magulu ophatikizidwa, popanda metadata (mwachitsanzo [GeoTiff1: B02, GeoTiff2: B03, GeoTiff3: B04, GeoTiff4: B05.]).

Ndi mtundu wa Zotsatira, zomwe zimayambitsa zojambulazo zidzaperekedwa ngati fayilo ya TIFF

Mlozera: zindikirani njira ya "Download by Crop". Kudula matailosi kumachitika molingana ndi magawo a ogwiritsa ntchito, ndiye kuti, geometry ya bbox yodziwika ndi ogwiritsa ntchito. M'malo omwe magawo ochepetsera sanakhazikitsidwe, zithunzi zonse zimatsitsidwa.

Mose mchitidwe

Gwiritsani Ntchito Mlanduwu 1: Kukonza Ntchito Zomangamanga, Dubai.

Cholinga: onani kupita patsogolo pantchito yomanga dera lalikulu chidwi (AOI)

Omvera anuwo: makampani onse ogwira ntchito yomanga

Vuto: Wogwiritsa adakhazikitsa kapena kuyendetsa dera lokondweretsedwa ndikusankha chithunzi chomwe chidatengedwa pa Julayi 19 kuchokera ku 2019. Chithunzichi chikuwonetseratu kuti chithunzithunzi sichikukhudza dera lonse lokondweretsedwa.

Yankho: pamenepa, wogwiritsa ntchito ayenera kusankha khadi yowoneratu yomwe ili ndi nambala yoyenera yazithunzi zomwe zimaphimba AOI yawo yonse, kuchokera pazotsatira zomwe zapangidwa, ndikudina chinthu cha "Mosaic".

Kutsiliza: Mose amalola kuwunika madera akuluakulu.

M'mbuyomu, kuwunikira madera akuluakulu kumafuna kuti wosuta asinthe pakati pazithunzi ndikuziphatikiza. Njirayi inali yovuta ndipo inatenga nthawi yayitali. Kuyambira lero, zonse nzachangu komanso zosavuta: sinthani AOI yanu ndi LandViewer ikusankhirani nokha zina zonse. 

Mlandu wogwiritsira ntchito 2: Kuwunika moto ku California

Cholinga: Fotokozerani malo omwe awonongeka, ndiye kuti, ikani cholozera cha NBR ndikutsitsa mawonekedwe a Mose.

Kufotokozera: Mu Novembala ya 2018, moto waukulu udabuka ku California, ndikupha anthu osachepera a 85. Pafupifupi nyumba zikwi khumi ndi zinayi (14,000) zidawonongeka, ndipo mahekitala pafupifupi zana ndi fifitini (115,000) adatayika. Akuluakulu am'deralo adawatcha kuti moto waukulu kwambiri m'mbiri ya dzikolo. Ndemanga iyi siyosadabwitsa, ngakhale kuti mahekitala zana limodzi (100,000) adatayikidwanso ndi chaka chathachi.

Akuluakulu a Local California adatumiza ozimitsa moto pafupifupi 5,000 kuti azimitsa motowo, yemwe samatha kupitiriza nawo motowo, womwe m'malo ena udafalikira mwachangu makilomita a 130 pa ola limodzi.

Yankho: Kuti muwone kuwonongeka kwa zigawo zomwe zakhudzidwazo, ndikofunikira kuyerekeza zojambula zowonongeka ndi zisanachitike ndi index ya NBR.

Pulogalamu ya 1: jambulani kapena thayitsani AOI m'dera lanu ndikukonda tsiku lomwe lisanagwe.

Chithunzi chisanachitike tsoka la 1Zotsatira zoyimira zojambula pazakuzungulira dera lachiwonetsero (AOI).

Paso 2: Sankhani khadi lowonera la Mosaic, pitani ku tabu ya "Band Combinations", kenako sankhani index ya NDR. Mu sitepe iyi, dongosololi likuwonetsa ma index owerengeka, owonetsedwa mumtundu walalanje. Kenako pitirizani ku "Download" tabu ndikusankha malo omwe mukufuna deta yofunikira.

Chithunzi cha 2: chithunzicho ndi cholozera cha NBR chikuwonetsa zomwe zidachitika pamoto.

Pulogalamu ya 3: Sankhani chithunzi cha pambuyo pa tsoka m'dera lomwelo la chidwi (AOI).

Chithunzi chisanachitike tsoka la 3: Zotsatira zakuyimira Mose pamalo onse okhudzidwa (AOI).

Pulogalamu ya 4: Pezani zotsatira zotsitsa za Mose pogwiritsa ntchito cholozera cha NBR, kutsatira ma algorithms omwewo omwe amapezeka mu sitepe 3.

Chithunzi cha 4: chochitika pambuyo pa tsoka chikuwonetsa dera lomwe lakhudzidwalo ndikuwona zowonongeka.

Zotsatira:  Madera omwe akhudzidwa akuwonetsedwa mofiira. Poyerekeza zithunzizi zisanachitike komanso zitatha tsoka ndi mfundo za NBR index, titha kuyesa kuwonongeka.

Lolani kuti Mose akuchitireni ntchitoyo

Pomaliza, Mose akupereka yankho lapadera kuti muthe kukhala ndi chithunzi chomwe chimakwaniritsa dera lomwe muli nalo, mosasamala kanthu za kukula, ndizotsatira zabwino. Mose amalola kuphatikiza zithunzi za satellite za tsiku ndi tsiku zomwe zimapezeka kuchokera ku sensor kuti zikhazikike, zomwe zimakonzedweratu kapena zolembedwa mosintha pa ntchentche, komanso mwayi wotsitsa zojambula kuti ziwunikenso pambuyo pake. Nenani kuti chisankho choyenera, kusintha kwa zithunzi, malo opanda kanthu ndi kujambula zithunzi zamanja, kwamuyaya.
