利用MapBasic划分精确农业田块网格方法的研究

Method of Making Field Grids by MapBasic in Precision Agriculture

精确农业要求对田块进行网格划分和命名 ,以便因地制宜地收集田间状态信息和实施变量投入。使用地理信息系统 (GIS)软件 Map Info Professional 6 .0及其二次开发语言 Map Basic 6 .0 ,以学校的运动场为例 ,对全球定位系统 (GPS)获取的原始卫星数据进行编程处理 ,探索了一种划分并命名田块网格的方法。应用结果表明 ,该方法可使全球定位系统和地理信息系统有机地衔接起来 。

To collect status messages of field and execute variable input in precision agriculture, the field should be plotted out and its grids are named accordingly. MapBasic 6.0 is the further development language of MapInfo Professional 6.0, which is a type of Geographical Information System (GIS) software. MapBasic and MapInfo can make field grids, but they are difficult to make grids according to the real shape of the field. So taking the playground of Nanling Campus of Jilin University for example, this paper explored one method of making and naming field grids. The original satellite data of the playground, collected by the Global Position System (GPS), were dealt with by the MapBasic programs. The result shows that this method can combine the GPS and GIS harmoniously, and can make field grids and name the grids conveniently.
