说明：  C#和ARCGIS engine编程，先根据点值生成栅格数据，可以输出为JPG\BMP等格式，然后进行渲染、分层着色，生成等值线，根据等值线实现任意点的插值查询
(C# and ARCGIS engine programming, the first based on the point value generating raster data can be exported as JPG \ BMP format, and then rendered, layered coloring, generate contours, to achieve a query at any point interpolation according to contour)
