Kusarudza mifananidzo yeSPOT kubva kuGoogle Earth

Ndinovimba kuti Mara pamusoro Cartesianos I ruregerero nokuda kwokubudisa mumhanyi sezvo pachena sezvo ichi chiri readme Google Earth, hehe

Asi iye, mukupindura chikumbiro ndakaona mazuva mashomanana apfuura mumatamba; pano chinyorwa. As takambotaura kareMukati zvakaipa Google Earth ndiye kuva chigadzirwa katarogu kuti Satellite mufananidzo rubatsiro, pakati pevamwe iyo mifananidzo yakagadziriswa yakatorwa neSatellite inonzi SPOT, pakupfuura ndiyo French abbreviation ye Satellite Pour l'Observation de la Terre kuti kubva ku SPOT5 yakatangwa mumifananidzo ye 2002 multispectral yepamusoro kune 2.5 mamita inowanikwa.

1 Ita basa rekutsvaga kweSPOT

Kuti uite shanduro yeStatellite yechipfigiro, inoitwa mujeri reboshwe rinoratidzwa mumufananidzo, nenzira iyi unogona kuona shotsu iripo mumiganhu yemarandan. Iwe unofanira kutora zvishoma kuti uvaone, uye mumifananidzo yepakati pezvivharo unowana rukwaniro kuti ukwanise kuongorora mufananidzo uye kunyange bhatani kuti uitenge.

2 Tsanangudzo yemifananidzo yeSPOT

Muchidimbu chechifananidzo, ruzivo rwunooneka se:

Satellite: SPOT 5 (Satellite yakaita pfuti)

Zuva: 23 DEC, 2007 18: 30: 56 UTC (Musi wekutora, United Time Central, kureva nguva yeUnited States Center)

Mutengo: 2.5 m (Kukura kwePixel uye kana mufananidzo wacho uri muvara kana girasiki)

Nzvimbo yekona: -5.03957 ° (kona yekutora zvine chekuita neiyo vector yaizoenda pakati penyika ... ndinofungidzira

Cherechedza: Miti inotaridzika inowanikwa mutsvuku pamifananidzo yevaravara. (Izvi zvinoreva kuti ruvara runofananidzwa nekududzirwa kwechiedza chetaneti, kwete kuti masango ari moto :))

Spot Image ndiyo inotungamirira mutapi we geographic ruzivo rwakabva kuchifananidzo chetaneti chekushandiswa kwevashandi uye yega.

"Nyika Imwe, Gore Rimwechete" inoratidza mifananidzo ichangoburwa yeSPOT yakawanikwa mumwedzi gumi nemiviri yapfuura. Iko kusarudzwa kwemifananidzo kubva pa12 metres kusvika ku2.50 metres resolution.

Izvi zvinoreva kuti mifananidzo inoratidzwa muGoogle Earth catalog haisi iyo yega iripo, asi pane iyo ine yakanyanya kudiwa ... uye kuti havazi vese vane resolution ye 2.50 metres asi inosiyana kusvika 20 metres pixel.

Izvi zvinoshandiswa hazvibatsiri nokuda kwemabasa akakwirira-mberi, imwe pixel isati yafamba mamiriyoni 20, zvino yava kufamba 2.50 kana pasi (GeoEye anovimbisa inozova ne0.25) asi dambudziko nderekuti nekuda kwekufukidzwa kwakakura kudaro, kutenderera kwepasi kune chinokanganisa, saka kuenzana kwakanangana kwenongedzo nekuremekedza kune imwe padhuze (anenge 100 metres, semuenzaniso) inoshanda chaizvo ... asi nekuremekedza iri kure (kutenderedza 2000 semuenzaniso) ... hapana zvivimbiso ... uye ndizvo zvinogadziriswa nekugadziriswa uye mutsauko unoonekwa kana uchienzanisa mufananidzo wakasarudzika wekubhururuka pamamirioni mashanu emamirimita, aine mapoinzi akakwana. kudzora… kumufananidzo wesataneti yakatorwa pamakiromita masere nemakumi mairi nemaviri pamusoro pegungwa.

Nekudaro, iyi mifananidzo inobatsira kwazvo kumapurojekiti emasango, kudzikisira njodzi, zvakatipoteredza, nhoroondo, nezvimwe. Mukana wavanazvo ndewokuti iwo masatellite anotorwa, ndokuti, mhedzisiro yedudziro yesatelite yakanangana nekuratidzira kwechiedza uye mamwe mahebhu akaomarara ... haasi mapikicha emuchadenga, asi zvirongwa zvakawanda zvine zvikumbiro zvinobvumidza kuongorora kwakakosha. pane iyi mhando yemufananidzo iyo inogona kuwanikwa nenzvimbo yekukwirisa dhata (DEM).

Kuti uzive kurongeka kwepakati pemifananidzo iyi, sarudza sarudzo "kuwana mufananidzo“, ipapo panobuda pani panenge paine rumwe ruzivo rwakadai selatitude nelongitude yepakati pemufananidzo, muzana yevhavha yegore, mutengo uye bhatani kuti uwane makotesheni.

Muenzaniso wandakuratidza unokosha €8,100, asi kana uchida kuona mamwe mavhavha unogona kuenda ku“kuona mamwe aquisition online” uye zvirokwazvo uchawana mifananidzo yakaderera kunyangwe isiri yazvino. Iyo "ichangoburwa" chiyero chakakodzera kutaurwa, inodzikisa mutengo uye mune dzimwe nguva mufananidzo kubva makore akati wandei apfuura unogona kubatsira zvakaenzana zvichienderana nezvinangwa kana kusaziva :).

4 Mifananidzo yezvikamu zvakananga

Kana ukangopinda mujeri rekusarudza iwe unogona kusarudza kana:

• Nharo dzenzvimbo
• Sarudza nharaunda, nyika, dhipatimendi, masuwa
• Sarudza uwandu hwepikisi, kubva ku2.5 kusvika ku 20 mamita, kana kutora kana kugadziriswa, kana 3D neminamato ekukwirira yemufananidzo weD digital (DEM)
• Zuva remufananidzo
• Maximum cloudiness
• Maximum angle of incidence

Kana imwe nguva mitemo yakasarudzwa, urongwa hunokuratidza iwe sarudzo dziripo uye maitengo.
