数字测图DigitalMappingDigitalTerrainMapDecoration数字地形图整饰数字地形图的整饰DecoratingDigitalTerrainMaps数字地形图的整饰要求与手工测图相似，但由于数字地形图使用绘图软件进行编辑，因此它的整饰内容比手工测图少。Therequirementsfordecoratingdigitalterrainmapsaresimilartothoseformanualmapping,butbecausedigitalterrainmapsareeditedusingdrawingsoftware,thecontentoftheirdecorationislessthanthatofmanualmapping.《国家基本比例尺地图图式第1部分：1:500，1:1000，1:2000地形图图式》《城市测量规范》《工程测量规范》《数字测绘成果质量检查与验收》数字地形图整饰常用的作业依据TheCommonlyUsedWorkingReferencesforDigitalTerrainMapDecorationNationalBasicScaleMapFormatPart1:1:500,1:1000,1:2000TopographicMapFormatsCodeofUrbanSurveyingSpecificationforEngineeringSurveyingQualityInspectionandAcceptanceofDigitalSurveyingandMappingResults0102Internaldecoration图内整饰图幅整饰Framedecoration数字地形图整饰的内容TheContentsofDigitalTopographicMapFinishing图内整饰就是对图廓内的图形进行整饰。Internaldecorationisthedecorationofgraphicswithinthemapborder.图内整饰的内容TheContentsofInternalDecoration控制点注记及取舍就是把测区各级基础控制点及埋石图根点全部进行注记，不埋石图根点可根据图面要求进行适当取舍，但均应将控制点符号标注于图面。Allthebasiccontrolpointsandrootpointsinthesurveyareaandtherootpointsoftheburiedstonemapsshouldbeannotated,andtherootpointsoftheburiedstonemapscanbeappropriatelyselectedaccordingtotherequirementsofthemapface.Thecontrolpointsymbolsshouldbemarkedonthemapface.01控制点注记及取舍Theannotationandselectionofcontrolpoints图内整饰的内容TheContentsofInternalDecoration1、等高线注记：即在每幅图均匀选中若干位置注记计曲线的高程，以方便读图者快速获取高程信息。Annotationofcontourlines:Thisinvolvesannotatingtheelevationofthecontourlinesatevenlyselectedlocationsoneachmaptofacilitateusersquicklyobtainingelevationinformation.02等高线处理Annotationofcontourlines图内整饰的内容TheContentsofInternalDecoration2、给山顶最高处和洼地最低处的封闭等高线加注示坡线，这对正、负地貌交错出现的区域（例如喀斯特地貌）尤其重要。Addslopelinestotheclosedcontourlinesatthehighestpointofthemountainandthelowestpointofthedepression.Thisisparticularlyimportantforareaswherepositiveandnegativeterrainareintermixed(suchaskarsttopography).图内整饰的内容TheContentsofInternalDecoration02等高线处理Annotationofcontourlines3、删减等高线节点：由于在对等高线进行打断、修改时，没有先将等高线的状态改为折线，使等高线上出现的非常密集的节点，增加图形数据的负荷。Deletecontourlinenodes:Becausewhenbreakingandmodifyingcontourlines,thestatusofcontourlinesisnotfirstchangedtopolyline,sothatverydensenodesappearoncontourlines,increasingtheloadofgraphicdata.图内整饰的内容TheContentsofInternalDecoration02等高线处理Annotationofcontourlines一般按每个坐标方格8-15个高程点进行注记，且必须均匀分布。Generally,8-15elevationpointsareannotatedineachcoordinategrid,andtheymustbeevenlydistributed.03高程点注记Theelevationpointannotation图内整饰的内容TheContentsofInternalDecoration对图廓外进行整饰称为图幅整饰。Thedecorationoftheborderoutsidethemapiscalledmapframedecoration.图幅整饰的内容TheContentsofInternalDecoration图形分幅，即将整个测区图形按规定要求划分为大小一致、排列整齐的图形。Graphicframedivision,whichistodividetheentiresurveyareagraphicaccordingtotherequiredspecificationsintoconsistentsizeandneatarrangementgraphics.01图形分幅Graphicframedivision图幅整饰的内容TheContentsofInternalDecoration图幅整饰的内容TheContentsofInternalDecoration【绘图处理】→【批量分幅】"Drawingprocessing"→"Batchframedivision"请选择图幅尺寸：(1)50×50(2)50×40（3）自定义尺寸<1>Pleaseselecttheframesize:(1)50×50(2)50×40(3)Customsize<1>输入测区一角：（在图形左下角点击左键）Inputonecornerofthesurveyarea:(clicktheleftbuttonatthelowerleftcornerofthegraphicatthistime)输入测区另一角：（在图形右上角点击左键）Inputanothercornerofthesurveyarea:(clicktheleftbuttonattheupperrightcornerofthegraphicatthistime)请输入批量分幅的取整方式：<1>取整到图幅<2>取整到十米<3>取整到米(1)（输入数字）Pleaseenterthebatchframedivisionroundingmethod:<1>Roundtotheframe(2)Roundtotenmeters(3)Roundtometers(1)(enteranumber)图幅整饰的内容TheContentsofInternalDecoration1:500图幅命名：“32821.00—511.25”"32821.00-511.25"fora1:500framegraphic.不论是标准分幅还是自由分幅，都应正确标注图幅外的元素，称为图幅整饰。Whetheritisstandardorfreeframedivision,elementsoutsidetheframeshouldbecorrectlyannotated,whichiscalledframedecoration.02图幅整饰Mapframedecoration图幅整饰的内容TheContentsofInternalDecoration图5-1Figure5-1【文件】【File】【CASS参数配置】【CASSParameterConfiguration】【图廓属性】【MapBorderProperties】
