运城地区arcgis软件的电子地图，有需要的可下载研究哦。-Yuncheng area ArcGIS software electronic map has the necessary research can be downloaded Oh.

MapObject 控件的使用之加入图层-MapObject control the use of the inclusion of layers

ＡｒｃＧＩＳGIS二次开发，说明。一些高级开者的好东西。-ArcGISGIS second development of note. Some senior opened the good things.

很好的一个ao开发的例子，用来将tin数据转化为raster数据的代码，自己编的，效率还可以。-a good example of the development of the ao, to be used for tin data into raster data code developed, but also efficient.

本程序是用vc编写的有关gis开发的基本框架 利用此框架可以进行更深层次的开发-this procedure is used in the preparation of vc gis the basic framework for the development of this framework can be used for the development of a deeper level

本软件基于MAPX5.0控件的开发这个系统本来应该注重于查询的,但查询有点问题,精确查询还好,模糊查询是错误的,大家可以看我的代码,模糊查询应该和精确查询是一样的,只是查的是所有图层罢了.所以我想请教一下大家怎样可以模糊查询,看了代码,照着做了,好像还不是很行,^_^.现在想把它完善一下,改的地方有鹰眼和查询结果做为浮动窗口,地图自动适应窗体的改变,其他还没想好.-MAPX5.0 based on the software controls the development of the system should focus on the inquiry, but for some problems, precision inquiries Fortunately, fuzzy inquiry is wrong, we can look at my code, fuzzy inquiry and precise inquiry should be the same, just check all the layers is just . Therefore, I would like to ask you about how fuzzy inquiry, read code suffices to follow them, do not seem to be OK ,^_^. want it perfect now that the place has changed and the Eagle Eye as a result of inquiries floating window, the map automatically adapt to changes in the form, not to other good . Oh

Examples of operate the map,such as zoom in,zoom out,pan and fix zoom.
