PAGE\*MERGEFORMAT50国家基本比例尺地形图图幅号查询系统的设计摘要图幅号的快速查询对于企业和用户有着广泛的用途。本文介绍了国家基本比例尺地形图图幅号编号旧方法和新方法，通过比较新旧图幅号编号方法的差异，表明了两者在不同比例尺下的转换关系，并且介绍了高斯坐标与大地坐标之间的换算关系，进而可从目标点的高斯坐标推算出该地的图幅号。本文介绍的图幅号查询系统是用VisualC++编程语言设计实现的，重要功能模块包括高斯坐标与大地坐标的转换、经纬度查询新图幅号、大地坐标查询新图幅号、新旧图幅号转换、查询图幅信息等，系统设计界面友好，查询结果准确，可以使得用户方便快捷地查询关于图幅号的信息。关键词：图幅号，查询系统，比例尺AbstractQuickQuerymapsheetnumberforbusinessesandconsumershaveawiderangeofuses.Thisarticledescribesthebasicnationalscaletopographicmapsheetnumberofoldandnewmethods,bycomparisonbetweentheoldandnewnumberingmapsheetnumber,indicatingtherelationshipbetweentheconversionatdifferentscales,andintroducedtheGaussiancoordinatesoftheearth'sconversionrelationshipbetweenthelandandthuscancalculatethemapsheetnumberfromtheGaussiancoordinatesofthetargetpoint.MapsheetnumberinquirysystemdescribedinthisarticleistouseVisualC++ProgrammingLanguageDesignandImplementationofanimportantfunctionmodulesincludeconvertingtheGaussiancoordinatesoftheearth,thelatitudeandlongitudequerynewmapsheetnumber,geodeticcoordinatesquerynewmapsheetnumber,oldmapsheetnumberconversionquerymapsheetinformation,systemdesignandfriendlyinterface,queryresultsareaccurate,sothattheusercanquicklyandeasilyqueryinformationaboutthemapsheetnumber.Keywords:mapsheetnumber，querysystem，scale目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc389857559"摘要PAGEREF_Toc389857559\hIHYPERLINK\l"_Toc389857560"AbstractPAGEREF_Toc389857560\hIHYPERLINK\l"_Toc389857561"第一章绪论PAGEREF_Toc389857561\h1HYPERLINK\l"_Toc389857562"1.1地形图图幅号概述PAGEREF_Toc389857562\h1HYPERLINK\l"_Toc389857563"1.1.1地形图分幅与编号PAGEREF_Toc389857563\h1HYPERLINK\l"_Toc389857564"1.1.2图幅号的作用PAGEREF_Toc389857564\h1HYPERLINK\l"_Toc389857565"1.2图幅号查询系统设计意义PAGEREF_Toc389857565\h2HYPERLINK\l"_Toc389857566"第二章我国地形图图幅号编号方法PAGEREF_Toc389857566\h3HYPERLINK\l"_Toc389857567"2.1国家基本比例尺旧图幅号编号PAGEREF_Toc389857567\h3HYPERLINK\l"_Toc389857568"2.2国家基本比例尺新图幅号编号PAGEREF_Toc389857568\h3HYPERLINK\l"_Toc389857569"
