Poyamba zithunzi za satana za 0.41 mts.

Pambuyo pa kukhazikitsidwa kwaposachedwa, 6 ya September, zithunzi zoyambirira zowonongeka zomwe zatengedwa ndi satana la GeoEye-1 zakhala zikuwonetsedwa kale.

Mipindi ya 0.41 ya kuthetsa, ndizokwanira, poganizira kuti chinthu chabwino chomwe anali nacho chinali pa sitima yapansi panthaka.

Tiyenera kuona kuti mungathe kuchita ndi mankhwala ngati amenewa zolinga cadastral kumene mwatsatanetsatane mtheradi ndi zogwirizana kuyambira chithunzi ichi kale chigamulocho ntchito orthophoto anatengedwa ndi ndege mlengalenga, chifukwa vuto ndi kusintha mwatsatanetsatane awo mtheradi chifukwa yayisinthidwa ndi chitsanzo cha digito chosavuta.

Ziyenera kumveka kuti chisankhochi sichikutanthauza kulondola, koma malo omwe ali ndi kukula kwa pixel. N'zoonekeratu kuti ntchitoyi ili ndi kulondola kwachibale, kotero kuti mtsinjewo umadutsa "kupyola kumeneko", komabe, mzere wa mtsinje kapena gawo la madzi a phiri lomwe limagwiritsidwa ntchito pofotokozera beseni kuti likhale ndi chilengedwe sichifanana ndi " malire ” ozindikirika pa mpanda, womwe kulondola kwake kotheratu kumatha kupita mtunda wa mita 25 koma mwiniwake angalole kukubayani 25 centimita.

Sananene zambiri ndi chilengezochi, koma sitikufuna kupitilira otsutsa mwanjira ya buku la Ken Alder lotchedwa “muyeso wa zinthu zonse", kotero apa tikumasulira ndakatulo ya Matteo O'Connell, ember chabe wa GeoEye:

"Ndife okondwa kumasula zithunzi zoyambirira kuchokera ku GeoEye-1, zomwe zimatifikitsa pafupi ndi chiyambi cha malonda a satellite ndi malonda kwa makasitomala athu. Ino ndi nthawi yofunikira, ndipo tikufuna kuthokoza antchito athu, makasitomala, makamaka National Geospatial-Intelligence Agency, othandizana nawo, mavenda, ndi osunga ndalama chifukwa cha thandizo lawo. "

Zithunzi zomwe GeoEye-1 imasonkhanitsa zili ndi masentimita 41 osintha zakuda ndi zoyera munjira yama panchromatic pomwe utoto (masekondi angapo) 1.65 mita. Zonsezi zomwe zawonetsedwa pachithunzichi ndizomwe zimapangidwa ndi kusakanikirana kwa chithunzi cha panchromatic komanso multispectral kuti chikhale ndi chithunzi chotsika kwambiri mu utoto wowona wa masentimita 50.

Titha kukhala otsutsa tikamafuna zomwe mankhwalawa sangapereke, koma tiyenera kukumbukira kuti ndizodabwitsa kuti chithunzichi chidatengedwa kutalika kwa mapazi zikwi zisanu komanso liwiro la 4.5 mamail pa sekondi ... palibe chochita ndi kukondana kwa ndege yomwe ikuuluka pa 5 mapazi zikwi kapena zozizwitsa za anyamata a Pict'Earth.

Pomaliza, tikuyenera kuyembekezera zambiri kuchokera ku izi pambuyo pazomwe zakhala zikuyembekezeka, ngakhale sizikudziwika bwino momwe mungapezere zithunzizi, kapena mitengo yake. Mutha kuwona zitsanzo zina pa ulalowu ndipo ngati mukufuna kudziwa nkhani kapena kulumikizana ndi Geo-eye, mutha kulembetsa kuutumikiwu.
