Description: 不错的代码，关于等直线的。
用三角网法绘制等值线，是在三角形的三条边上用线性内插方法寻找等值点，这种方法的机理是将每个三角形看作是空间的一个平面，这就要求在每个三角形的三个顶点内的地貌形态无明显的变化，故此希望将其中最靠近的三个点构成三角形，以符合上述机理，使插补的等值点精度较高，更好的反映地貌的实际形态。符合这些条件的三角形称之为“最佳三角形”-Good code, such as a straight line on the. With a triangular mesh contour map is the edge of the triangle with the three methods of linear interpolation to find the equivalent point, the mechanism of this method is to each triangle as a space plane, which requires each triangles three vertices with no obvious patterns of geomorphic change, it wished to put the three points closest to constitute a triangle in order to comply with the above mechanism, so that the equivalent interpolation points higher accuracy, better reflects the landscape the actual shape. Applying these criteria to the triangle known as the Platform: |

Description: 附件中是一些ArcGIS Engine代码的集合,主要是一些比较常见的GIS功能的实现方法,作者用C#+AE都实现了,可能包括基本GIS地图操作,空间分析,几何或交通网络分析等,内容还不错,可以让不太懂的人学习一下,也可以让比较懂的人借鉴一下。
具体成果有:（1）开发了一些常规的GIS基本功能，如放大、缩小、全屏、查询、查找、量测、鹰眼等；（2）开发了一些常用的空间分析功能，如距离计算、密度分析、栅格插值、表面分析、象素统计、数据转换等。（3）网络分析功能，如计算最临近服务设施。（4）几何网络设施分析，如水管和阀门关停、上朔追踪、剖面分析等-Attached is a collection of some ArcGIS, main Engine code is some common method to realize the function of GIS, the authors use c#+ AE is realized, which may include basic GIS spatial analysis, operation, map or network traffic analysis geometry, content is good, can let the person don t understand, also can let the person is to understand the reference.
Specific results are as follows: (1) the development of GIS basic function of some conventional, such as amplifier, narrow, screen, query, search, measurement, and an eagle s eye, etc. (2) developing some common features, such as the space analysis, calculation and analysis of distance, the density of grid interpolation surface analysis, and statistical data, convert, and pixels. (3) network analysis function, such as the most near service facilities. (4) geometric network facilities, such as pipe and analysis on the valve shut, new track, profile analysis, etc Platform: |
