从网上下载的代码资料，看了感觉还不错，拿来与大家分享。 近年来，地理信息系统（GIS）是储存和处理与地理空间分布有关信息的集合。在各行各业得到越来越广泛的应用，GIS以其混合数据结构和独特的地理空间分析功能独树一帜 在税务系统中也开始广泛的应用，不仅仅表现为提高管理的效率，而且增加了管理的功能。通过对组件式GIS技术的分析，还比较了WebGIS和VC++等技术，我们决定选用VC++基于进行GIS的开发企业分布地理信息系统。 本系统借助计算机完成企业的分布的电子地图，首先注册才能获取应用的权限，实现了鹰眼功能，一个地区地图的放大 缩小 漫游，箭头 编号标柱 点选 框选 圆选 选择符号 图层控制 按企业编号，企业名字查找 及企业的添加，删除等功能，当然后几项功能只有管理员才可以有使用权限。当选择选择方式进行选择之后，可以显示出被选中企业的名字，然后你可以点击企业的名字在地图上就会把这个企业的位置显放大显示在中心位置，况且不断的闪烁，还可以显示企业的详细信息。
