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，但實景掃描數(shù)字化精度通常比手動數(shù)字化高。”所以選項B“higher”（更高）是正確的。而其他選項中，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C：Thespectralemissivityofanobjectanditsspectralabsorptanceareequalinthesamedimension.\n\n解釋：在紅外光譜中，一個物體的光譜發(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C是正確的。'WhichofthefollowingisnotGISoutputdevices?()

A:GraphicdigitizerB:GraphicdisplayterminalC:printerD:Plotter答案:AI參考:選項【A:Graphicdigitizer】不是GIS輸出設備。\n\nGIS（地理信息系統(tǒng)）輸出設備通常包括圖形顯示器終端、打印機和繪圖儀等。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。打印機可以將GIS數(shù)據(jù)打印成紙質文檔，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，它所對應的電磁波波長較長，是一種短波輻射。因此，選項D是正確答案。其他選項中，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A、C都不正確。'Thecolorofforestinastandardfalse-colorimageryis（）.

A:blackB:redC:greenD:blue答案:AI參考:正確選項是【C:green】。森林在標準假彩色圖像中的顏色是綠色。這是因為假彩色圖像通常使用紅綠藍三色作為基本色彩，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。其他選項中，黑色、紅色和藍色都不符合實際情況。'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)星同時搭載了OLI（光學成像儀）、ETM+（增強型熱紅外傳感器）和TIRS（熱紅外輻射計）三種傳感器，是同時搭載這三款傳感器的衛(wèi)星。因此，B選項是正確答案。'（)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:正確選項是【C:datum、centerline】。\n\n第一個空填datum，指的是基準線，指的是投影面的法線，也就是投影面與參考球相交的線。第二個空填centerline，指的是中心線，它定義了地圖投影的中心。因此，選項C是正確的。其他選項的含義與題意不符。'Whichofthefollowingisnotadescriptionofimagetexture?（）

A:theapparentsmoothnessofanimageregionB:theapparentroughnessofanimageregionC:thefrequencyoftonalchangeonanimageD:relativebrightnessofobjectsintheimage答案:AI參考:正確答案是D:relativebrightnessofobjectsintheimage。\n\n選項D描述的是圖像中物體的相對亮度，而其他選項都是關于圖像紋理的描述。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A、B、C都是正確的描述。因此，選項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碼和導航碼，其中P碼是最高精度碼，C/A碼是最常用的基本碼，導航碼是用于確定衛(wèi)星位置的。因此，選項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)星影像的分像片素數(shù)是固定的2048個色階。該問題只需要通過看題目所給的關鍵詞直接找出答案即可，不需要再進一步的分析推理。\n所以正確選項為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，應該選擇等積投影，選項D是等積投影的一種，因此是正確答案。選項A、B、C都不是等積
