A:slowerB:higherC:fasterD:lower答案:AI參考:正確答案是B:higher。\n在句子中提到“盡管線條仍然需要人工描繪,但實(shí)景掃描數(shù)字化精度通常比手動數(shù)字化高。”所以選項(xiàng)B“higher”(更高)是正確的。而其他選項(xiàng)中,slower(更慢)、faster(更快)和lower(更低)都與句子的含義不符。因此,正確答案是B。'()statesthatintheinfraredspectrum,thespectralemissivityofanobjectanditsspectralabsorptanceareroughlythesameinthesamedimension.
答案:AI參考:選項(xiàng)C:Thespectralemissivityofanobjectanditsspectralabsorptanceareequalinthesamedimension.\n\n解釋:在紅外光譜中,一個(gè)物體的光譜發(fā)射率與其光譜吸光度在相同的維度上大致相等。這是紅外輻射與吸收的基本原理之一。因此,選項(xiàng)C是正確的。'WhichofthefollowingisnotGISoutputdevices?()
A:GraphicdigitizerB:GraphicdisplayterminalC:printerD:Plotter答案:AI參考:選項(xiàng)【A:Graphicdigitizer】不是GIS輸出設(shè)備。\n\nGIS(地理信息系統(tǒng))輸出設(shè)備通常包括圖形顯示器終端、打印機(jī)和繪圖儀等。圖形顯示器終端可以將GIS數(shù)據(jù)以圖形方式展示出來,便于觀察和分析。打印機(jī)可以將GIS數(shù)據(jù)打印成紙質(zhì)文檔,便于存檔和分享。繪圖儀則可以用于繪制地圖、等值線圖、三維地形圖等GIS相關(guān)的圖形圖像。而圖形數(shù)字儀主要用于輸入數(shù)據(jù),不是輸出設(shè)備。因此,答案是A:Graphicdigitizer。'The()isaregionofshort-waveradiationthatliesbetweentheX-rayregionandthelimitofhumanvision.
A:ultravioletspectrumB:visiblespectrumC:microwaveenergyD:infraredspectrum答案:AI參考:正確答案是D:infraredspectrum。\n紅外光譜是介于可見光譜與微波輻射之間的電磁輻射,它所對應(yīng)的電磁波波長較長,是一種短波輻射。因此,選項(xiàng)D是正確答案。其他選項(xiàng)中,紫外線光譜屬于可見光譜,微波能量屬于電磁波譜中的一部分,與紅外光譜不同。因此,選項(xiàng)A、C都不正確。'Thecolorofforestinastandardfalse-colorimageryis().
A:blackB:redC:greenD:blue答案:AI參考:正確選項(xiàng)是【C:green】。森林在標(biāo)準(zhǔn)假彩色圖像中的顏色是綠色。這是因?yàn)榧俨噬珗D像通常使用紅綠藍(lán)三色作為基本色彩,而森林中的樹木通常呈現(xiàn)綠色,因此森林在假彩色圖像中的顏色也被表示為綠色。其他選項(xiàng)中,黑色、紅色和藍(lán)色都不符合實(shí)際情況。'Foropticalremotesensingsystems,thenominalspatialresolutionofthesensorsystemlargelydependsonthesizeof()projectedontheground.
A:LMPB:IFOVC:GSDD:GRD答案:AI參考:正確答案是B:IFOV。\n在光學(xué)遙感系統(tǒng)中,傳感器的名義空間分辨率主要取決于地面上的像元大小,也就是IFOV(視場焦距)。因此,答案為B。A選項(xiàng)LMP(地面分辨率)通常用于描述數(shù)字圖像或傳感器分辨率,而不是空間分辨率。C選項(xiàng)GSD(地理空間分辨率)通常用于描述地理信息系統(tǒng)中的數(shù)據(jù)分辨率,而D選項(xiàng)GRD(地理參照系統(tǒng))通常用于描述地理空間數(shù)據(jù)的參照系統(tǒng)。'UnliketheAmericanGPS,RussianGLONASS,andEuropeanGalileosystems,whichusemedianEarthorbitsatellites,BeiDou-1usessatellitesin().
A:Sun-synchronousorbitB:CircularorbitC:GeostationaryorbitD:Nearpolarorbit答案:AI參考:答案為C:Geostationaryorbit。\n\n中國北斗衛(wèi)星導(dǎo)航系統(tǒng)(BeiDou-1)與美國的GPS、俄羅斯的GLONASS和歐洲的Galileo系統(tǒng)不同,這些系統(tǒng)使用的是中地球軌道衛(wèi)星,而北斗-1使用的是地球靜止軌道衛(wèi)星。地球靜止軌道(Geostationaryorbit)也被稱為GSO,是指衛(wèi)星在赤道上空約35700千米的高度上運(yùn)行,相對于地球表面靜止不動。因此,正確答案是C。'WhichsatellitecarriesOLI,ETM+andTIRSsensorsatthesametime?()
A:Landsat4B:Landsat7C:Landsat8D:Landsat3答案:AI參考:正確答案是B:Landsat7。\n\nLandsat7衛(wèi)星同時(shí)搭載了OLI(光學(xué)成像儀)、ETM+(增強(qiáng)型熱紅外傳感器)和TIRS(熱紅外輻射計(jì))三種傳感器,是同時(shí)搭載這三款傳感器的衛(wèi)星。因此,B選項(xiàng)是正確答案。'()isidealformeteorologicalorcommunicationsatellites,designedtomaintainaconstantpositionrelativetoaspecificareaontheearth'ssurface.
A:Sun-synchronousorbitB:NearpolarorbitC:CircularorbitD:Geostationaryorbit答案:AI參考:正確答案是A:Sun-synchronousorbit。\nSun-synchronousorbit是一種理想的用于氣象或通信衛(wèi)星的軌道,它能夠保持相對于地球表面特定區(qū)域的恒定位置。因此,答案為A。Nearpolarorbit、Circularorbit和Geostationaryorbit雖然也是軌道類型,但與題干中的描述不符。'The()referstothelineoftangencyoftheprojectionsurfaceandthereferenceglobe,andthe()definesthecenterofthemapprojection.()
A:standardline、centerlineB:standardline、datumC:datum、centerlineD:centerline、standardline答案:AI參考:正確選項(xiàng)是【C:datum、centerline】。\n\n第一個(gè)空填datum,指的是基準(zhǔn)線,指的是投影面的法線,也就是投影面與參考球相交的線。第二個(gè)空填centerline,指的是中心線,它定義了地圖投影的中心。因此,選項(xiàng)C是正確的。其他選項(xiàng)的含義與題意不符。'Whichofthefollowingisnotadescriptionofimagetexture?()
A:theapparentsmoothnessofanimageregionB:theapparentroughnessofanimageregionC:thefrequencyoftonalchangeonanimageD:relativebrightnessofobjectsintheimage答案:AI參考:正確答案是D:relativebrightnessofobjectsintheimage。\n\n選項(xiàng)D描述的是圖像中物體的相對亮度,而其他選項(xiàng)都是關(guān)于圖像紋理的描述。圖像紋理通常包括圖像區(qū)域的表面粗糙度、光滑度、頻率和灰度變化等特征,因此選項(xiàng)A、B、C都是正確的描述。因此,選項(xiàng)D不是圖像紋理的描述。'WhichofthefollowingisnotthebasiccodeinGPS?()
A:P-codeB:NormalcodeC:C/AcodeD:Navigationcode答案:AI參考:正確答案是B:Normalcode。\n\nGPS的基本碼包括P碼、C/A碼和導(dǎo)航碼,其中P碼是最高精度碼,C/A碼是最常用的基本碼,導(dǎo)航碼是用于確定衛(wèi)星位置的。因此,選項(xiàng)B“Normalcode”不是GPS的基本碼。'TheradiometricresolutionofVegetationsensorcarriedbySPOT-4is10bit,howmanytonelevelsdoestheVegetationimageryhave?()
A:512B:2048C:1024D:256答案:AI參考:答案:B\n解析:該衛(wèi)星影像的分像片素?cái)?shù)是固定的2048個(gè)色階。該問題只需要通過看題目所給的關(guān)鍵詞直接找出答案即可,不需要再進(jìn)一步的分析推理。\n所以正確選項(xiàng)為B,即2048。'IfIwanttopreserveshapeduringprojection,Ineedtochoose()mapprojection.
A:EquidistantB:EquivalentC:AzimuthalD:Conformal答案:AI參考:正確答案是D:Conformal。\n在投影過程中,如果想要保持形狀不變,應(yīng)該選擇等積投影,選項(xiàng)D是等積投影的一種,因此是正確答案。選項(xiàng)A、B、C都不是等積
