FromCoordString

汇总

FromCoordString 函数将坐标系注记字符串转换为 WGS84 坐标中的 PointGeometry 对象。

讨论

要创建坐标系注记字符串，请使用 PointGeometry 对象的 toCoordString 方法。

语法

FromCoordString(string, notation)

参数 说明 数据类型

string

The input coordinates.

String

notation

Specifies the coordinate system notation of the input string.

  • DD— Decimal degrees is used, for example, 34.05719570N 117.19647020W.

  • DDM— Degrees decimal minutes is used, for example, 34 03.43174200N 117 11.78821200W.

  • DMS— Degree Minute Seconds, is used, for example, 34 03 25.90452000N 117 11 47.29272000W.

  • GARS— Global Area Reference System is used, for example, 126LJ47. It is based on latitude and longitude, and it divides and subdivides the world into cells.

  • GEOREF— World Geographic Reference System is used, for example, EJCE4821203432.

  • MGRS— Military Grid Reference System is used, for example, 11SMT8186968515.

  • USNG— United States National Grid is used, for example, 11S MT 81869 68515.

  • UTM— Universal Transverse Mercator is used, for example, 11S 481868 3768515. It is based on zone number, MGRS latitude band, and the easting and northing planar coordinate pair in that zone.

  • UTMNS— Universal Transverse Mercator (no spaces) is used, for example, 11N4818683768515. It is based on zone number, hemisphere designator, and the easting and northing planar coordinate pair in that zone.

String

返回值

数据类型 说明

PointGeometry

坐标系为 WGS84 (wkid=4326) 的 PointGeometry 对象。

代码示例

FromCoordString 示例

根据美国国家格网字符串创建 PointGeometry 对象。

import arcpy
coord_string = '14S PB 59361 43195'
point_geometry = arcpy.FromCoordString(coord_string, 'USNG')
