A:slowerB:higherC:fasterD:lower答案:AI参考:正确答案是B：higher。\n在句子中提到“尽管线条仍然需要人工描绘，但实景扫描数字化精度通常比手动数字化高。”所以选项B“higher”（更高）是正确的。而其他选项中，slower（更慢）、faster（更快）和lower（更低）都与句子的含义不符。因此，正确答案是B。'()statesthatintheinfraredspectrum,thespectralemissivityofanobjectanditsspectralabsorptanceareroughlythesameinthesamedimension.

答案:AI参考:选项C：Thespectralemissivityofanobjectanditsspectralabsorptanceareequalinthesamedimension.\n\n解释：在红外光谱中，一个物体的光谱发射率与其光谱吸光度在相同的维度上大致相等。这是红外辐射与吸收的基本原理之一。因此，选项C是正确的。'WhichofthefollowingisnotGISoutputdevices?()

A:GraphicdigitizerB:GraphicdisplayterminalC:printerD:Plotter答案:AI参考:选项【A:Graphicdigitizer】不是GIS输出设备。\n\nGIS（地理信息系统）输出设备通常包括图形显示器终端、打印机和绘图仪等。图形显示器终端可以将GIS数据以图形方式展示出来，便于观察和分析。打印机可以将GIS数据打印成纸质文档，便于存档和分享。绘图仪则可以用于绘制地图、等值线图、三维地形图等GIS相关的图形图像。而图形数字仪主要用于输入数据，不是输出设备。因此，答案是A:Graphicdigitizer。'The()isaregionofshort-waveradiationthatliesbetweentheX-rayregionandthelimitofhumanvision.

A:ultravioletspectrumB:visiblespectrumC:microwaveenergyD:infraredspectrum答案:AI参考:正确答案是D：infraredspectrum。\n红外光谱是介于可见光谱与微波辐射之间的电磁辐射，它所对应的电磁波波长较长，是一种短波辐射。因此，选项D是正确答案。其他选项中，紫外线光谱属于可见光谱，微波能量属于电磁波谱中的一部分，与红外光谱不同。因此，选项A、C都不正确。'Thecolorofforestinastandardfalse-colorimageryis（）.

A:blackB:redC:greenD:blue答案:AI参考:正确选项是【C:green】。森林在标准假彩色图像中的颜色是绿色。这是因为假彩色图像通常使用红绿蓝三色作为基本色彩，而森林中的树木通常呈现绿色，因此森林在假彩色图像中的颜色也被表示为绿色。其他选项中，黑色、红色和蓝色都不符合实际情况。'Foropticalremotesensingsystems,thenominalspatialresolutionofthesensorsystemlargelydependsonthesizeof()projectedontheground.

A:LMPB:IFOVC:GSDD:GRD答案:AI参考:正确答案是B:IFOV。\n在光学遥感系统中，传感器的名义空间分辨率主要取决于地面上的像元大小，也就是IFOV（视场焦距）。因此，答案为B。A选项LMP（地面分辨率）通常用于描述数字图像或传感器分辨率，而不是空间分辨率。C选项GSD（地理空间分辨率）通常用于描述地理信息系统中的数据分辨率，而D选项GRD（地理参照系统）通常用于描述地理空间数据的参照系统。'UnliketheAmericanGPS,RussianGLONASS,andEuropeanGalileosystems,whichusemedianEarthorbitsatellites,BeiDou-1usessatellitesin（）.

A:Sun-synchronousorbitB:CircularorbitC:GeostationaryorbitD:Nearpolarorbit答案:AI参考:答案为C：Geostationaryorbit。\n\n中国北斗卫星导航系统（BeiDou-1）与美国的GPS、俄罗斯的GLONASS和欧洲的Galileo系统不同，这些系统使用的是中地球轨道卫星，而北斗-1使用的是地球静止轨道卫星。地球静止轨道（Geostationaryorbit）也被称为GSO，是指卫星在赤道上空约35700千米的高度上运行，相对于地球表面静止不动。因此，正确答案是C。'WhichsatellitecarriesOLI,ETM+andTIRSsensorsatthesametime？（）

A:Landsat4B:Landsat7C:Landsat8D:Landsat3答案:AI参考:正确答案是B:Landsat7。\n\nLandsat7卫星同时搭载了OLI（光学成像仪）、ETM+（增强型热红外传感器）和TIRS（热红外辐射计）三种传感器，是同时搭载这三款传感器的卫星。因此，B选项是正确答案。'（)isidealformeteorologicalorcommunicationsatellites,designedtomaintainaconstantpositionrelativetoaspecificareaontheearth'ssurface.

A:Sun-synchronousorbitB:NearpolarorbitC:CircularorbitD:Geostationaryorbit答案:AI参考:正确答案是A:Sun-synchronousorbit。\nSun-synchronousorbit是一种理想的用于气象或通信卫星的轨道，它能够保持相对于地球表面特定区域的恒定位置。因此，答案为A。Nearpolarorbit、Circularorbit和Geostationaryorbit虽然也是轨道类型，但与题干中的描述不符。'The（）referstothelineoftangencyoftheprojectionsurfaceandthereferenceglobe,andthe（）definesthecenterofthemapprojection.（）

A:standardline、centerlineB:standardline、datumC:datum、centerlineD:centerline、standardline答案:AI参考:正确选项是【C:datum、centerline】。\n\n第一个空填datum，指的是基准线，指的是投影面的法线，也就是投影面与参考球相交的线。第二个空填centerline，指的是中心线，它定义了地图投影的中心。因此，选项C是正确的。其他选项的含义与题意不符。'Whichofthefollowingisnotadescriptionofimagetexture?（）

A:theapparentsmoothnessofanimageregionB:theapparentroughnessofanimageregionC:thefrequencyoftonalchangeonanimageD:relativebrightnessofobjectsintheimage答案:AI参考:正确答案是D:relativebrightnessofobjectsintheimage。\n\n选项D描述的是图像中物体的相对亮度，而其他选项都是关于图像纹理的描述。图像纹理通常包括图像区域的表面粗糙度、光滑度、频率和灰度变化等特征，因此选项A、B、C都是正确的描述。因此，选项D不是图像纹理的描述。'WhichofthefollowingisnotthebasiccodeinGPS?（）

A:P-codeB:NormalcodeC:C/AcodeD:Navigationcode答案:AI参考:正确答案是B：Normalcode。\n\nGPS的基本码包括P码、C/A码和导航码，其中P码是最高精度码，C/A码是最常用的基本码，导航码是用于确定卫星位置的。因此，选项B“Normalcode”不是GPS的基本码。'TheradiometricresolutionofVegetationsensorcarriedbySPOT-4is10bit,howmanytonelevelsdoestheVegetationimageryhave?()

A:512B:2048C:1024D:256答案:AI参考:答案：B\n解析：该卫星影像的分像片素数是固定的2048个色阶。该问题只需要通过看题目所给的关键词直接找出答案即可，不需要再进一步的分析推理。\n所以正确选项为B，即2048。'IfIwanttopreserveshapeduringprojection,Ineedtochoose()mapprojection.

A:EquidistantB:EquivalentC:AzimuthalD:Conformal答案:AI参考:正确答案是D：Conformal。\n在投影过程中，如果想要保持形状不变，应该选择等积投影，选项D是等积投影的一种，因此是正确答案。选项A、B、C都不是等积
