摘要
利用VisualBasic语言和MapObjects地图组件,实现了WGS-84地理坐标系到UTM投影坐标系的变换,可用于农业机械行走距离、地块面积等的量算。还使用VB编程实现了对UTM投影的反算,根据UTM投影坐标,反算出经纬度坐标。通过程序测试表明,其计算精度完全满足在精准农业应用中的要求。
Basing on the visual basic language and the MapObjects map COM, the WGS-84 geographical coordinates system transforms to the UTM projection coordinates system was realized. It could be used for the calculation of travel distance of the agricultural machinery, area of field, etc. This paper also realized the inverse calculation of UTM projection using the programming of VB, according to UTM projection coordinate, could calculate the longitude and latitude coordinate. By the procedure tested, the precision totally responds to the request of precision agriculture.
