Mathematica中的geodesy类

Geodesy

Mathematica provides state-of-the-art high-precision geodesy computation, supporting all standard datums and projections.

FromDMS onvert from degrees, minutes, and seconds to decimal degrees

DMSString, DMSListconvert from decimal degrees to degrees-minutes-seconds form

Latitude, Longitude, LatitudeLongitudeextract latitude, longitude

Degree （。）conversion factor from radians to degrees (entered as Esc\[ThinSpace]deg\[ThinSpace]Esc)

 

GeoPosition  geodetic position specified by latitude and longitude

GeoPositionXYZ GeoPositionENU GeoGridPosition projected position in a cartographic grid

 

GeoDistance  distance between geodetic positions

GeoDirection azimuthal direction between geodetic positions

GeoDestination position at a given distance and direction from a point

 

GeodesyData data on reference ellipsoids and geodetic datums

GeoProjectionData data on cartographic projections

 

CityData, CountryData  give latitude, longitude of cities, countries (in degrees)

AstronomicalData  computable data on planets, stars, moons, etc.

 

$GeoLocation  settable current geodetic location

FindGeoLocation try to find the current location using GPS, geoIP, etc.

FromDMS —将度、分、秒转换为十进制的度

DMSString, DMSList — 将十进制的度转换为度-分-秒的形式

Latitude, Longitude, LatitudeLongitude — 提取纬度，经度

Degree (°) — 从弧度到度的转换因子（输入 Esc deg Esc）

   

GeoPosition — 通过经度和纬度指定的测量位置

GeoPositionXYZ  ▪ GeoPositionENU

GeoGridPosition — 地图网格上的投影位置

  

GeoDistance — 测量位置间的距离

GeoDirection — 两个测量位置间的方位角

GeoDestination — 从一点给定距离和方向的位置

   

GeodesyData — 参考椭圆体和测量基准的数据

GeoProjectionData — 地图投影的数据

 

CityData, CountryData — 给出城市、国家的纬度、经度（用度表示）

AstronomicalData — 关于行星、恒星、月亮等的可计算数据

    

$GeoLocation — 设置当前测量位置

FindGeoLocation — 通过GPS、geoIP等尽量找到当前位置
