mapgis二次开发空间分析员程序代码可供二次开发人员参考(MAPGIS secondary development of space analyst program code for the secondary development of reference)
最近几年,社会上地理信息系统和电子地图技术越来越受到大家的关注,很多单位和个人都投入了大量的人力和物力进行了相关的设计开发。在这些实际的开发问题中,我想就公交车换乘自动查询系统的核心算法的设计和分析做一个不成体统的研究,还希望同志们能帮我指正错误,帮助提高。(In recent years, the community of GIS and digital map technology is receiving increasing attention to the U.S., many units and individuals have invested considerable human and material resources to carry out the relevant design and development. In the development of these practical issues, I would like to change bus system automatically query the core of algorithm design and analysis不成体统to do a study, and also hope to help my comrades error correction to help improve.)
DEM中提取地形特征的一个新算法,简单实用(DEM to extract topographical features of a new algorithm, simple and practical)
实现地图符号的定制与开发 有一定的参考价值(achieve map symbol customization and the development of certain reference value)
导航电子地图软件,借助于ESRI公司的mapobjects和arcobjects软件,用MFC开发,本代码已经过编译和调试,能正常运行,实现对电子地图进行拖动的功能.(electronic map navigation software, using ESRI, the mapobjects and arcobjects software, Using MFC development, the code has been compiling and debugging, normal operation can realize the electronic map scrolling function.)
jis控件mapobject在vc环境下 示例代码(jis Control mapobject vc environment in the sample code)
师兄用VC写的由湿地DEM生成的三维模型,赋有纹理,可以动态漫游,地理分析。希望对搞GIS开发的朋友有所帮助。包含DEM和纹理数据,所以有点大,请耐心下载。(senior VC written by DEM wetlands generated 3D model, endowed with texture, dynamic roaming, geographic analysis. Hope to engage in the development of the GIS friends help. DEM contains data and texture, a bit, please download patience.)
用mapobject 实现坐标投影的读取(mapobject used to achieve the projection coordinates read)
该文档能为初学者更好的了解用mapinfo空件开发gis带来的好处(the document for beginners with a better understanding of the development of MapInfo empty pieces of the benefits gis)
一个用VC++编写的DEM数据的读写和显示程序。(a VC DEM data prepared by the reader and display procedures.)
说明: 本程序可以实现用c sharp编写的GIS图形中通过点击使2d点和图形变成3d图形的功能(this procedure can be achieved using the c sharp graphics prepared by the GIS through it so 2d point and graphics into 3d graphics functions)
说明: 这就是陈建春的《用Visual C++开发GIS系统》的配套代码。 用来给初学者熟悉VC++图形编程很不错,我当初学MFC的时候就是照着这本书上手的。但作为一个GIS系统来说缺少一些必要的 要素,比如大数据量的管理、空间索引、符号化、投影等等等等等。以现在的眼光看来整个系统的架构设计也不是太好。 这本书再版后改名为《矢量图形系统开发与编程》,内容变化不大("using Visual C development of GIS systems" supporting code. For beginners to the VC familiar with graphical programming quite well, and I had the time to learn MFC is shining on this book in the business. But as a GIS systems lack the necessary elements, such as the large amount of data management, spatial indexing, symbols, such as projectors, etc.. Now the point of view of the entire system architecture design is not too good. This book reprinted later renamed as "vector graphics systems development and programming", little change)
Shapefile C是一个C库,用于读写ESRI形状文件和相关的DBF文件。支持所有的几何形状。Shapelib 被广泛用于商业和自由项目。Shapelib 包含命令行工具,用于转储、求子集、剪切、旋转、缩放、和重新生成形状文件。 (SHAPEFILES C is a C library for reading and writing ESRI shape files and documents related to the DBF. Support all of the geometry. Shapelib been widely used in commercial and free items. Shapelib includes a command line tool for the dump, in her collection, shear, rotate, zoom, and was re-shape paper.)
在VC中利用MAPX实现各种性质的图层的使用,其中不包括细化图层。(in VC Connection use of various layers of the nature of the use, which does not include the thinning layer.)
