Mapinfor转KML工具源码采用Mapbasic语言编程，可以根据个人需要进行修改应用-　Mapinfo2Google converts MapInfo layers in a map window to a Google Earth KML file.　

　Supports point, line, polyline, region, rectangle and text object types.

　ARC and ELLIPSE (circle) objects are not supported and are skipped

　Object style information extracted but not currently used. Use Google Earth client instead.
