对于SuperMap 不支持或者用户自定义的投影进行坐标投影转换

范例使用SuperMap iClient 7C for JavaScript开发模式,通过proj4对SuperMap 不支持或者用户自定义的投影进行投影转换。一般通过GPS采集到的坐标是经纬度坐标,而地图是投影坐标系,就可以用该方法转换。虽然转换结果有一定的误差,但可以满足用户的一般需求。该示例演示在图层初始化完成事件回调函数中调用 transform() 方法和在通过设置map的 projection 和 displayProjection 属性两种方式实现坐标转换。

Obstructions to Fibering a Manifold

Abstract. Given a map f : M ! N of closed topological manifolds we define torsion obstructions whose vanishing is a necessary condition for f being homotopy equivalent to a projection of a locally trivial fiber bundle. If N = S1, these torsion obstructions are identified with the ones due to Farrell

VB+mo的坐标转换换系统

VB+mo的坐标转换换系统在MO中,每个Map或MapLayer对象都和一个坐标系对象发生联系,这个坐标系对象可以是地理坐标系(GeoCoordSys)对象,也可以是投影坐标系(ProjCoordSys)对象。 地理坐标系(GeoCoordSys)是MO中最常用的坐标系对象,它用经纬度描述地面上的位置。描述位置时,用Datum属性设置其基准面,用PrimeMeridian属性设置其本初子午线,用Unit属性设置其坐标系单位。 标准的地理坐标系的改变可以通过用Type属性来设置GeographicCoordSys常数来完成,参见附录D.8。通过设置其Datum、PrimeMeridian和Uni
