Convert latitude, longitude to distance from equator in kilometers and round to nearest kilometer

由 时光总嘲笑我的痴心妄想 提交于 2020-01-14 03:48:27
问题 For each coordinate I have, I find the distance from the equator in kilometers giving me two distances: from pyproj import Geod wgs84_geod = Geod(ellps='WGS84') _,_, lon_dist = wgs84_geod.inv(0, 0,lon, 0) _,_, lat_dist = wgs84_geod.inv(0, 0,0, lat) As a sanity check,I can recalculate the original coordinate from these values as follows (assume the direction from the equator coordinate (0,0) is North and West: _, new_lat, _ = wgs84_geod.fwd(0,0, 0, lat_dist) new_lon, _, _ = wgs84_geod.fwd(0, 0

Calculate 3D point coordinates using horizontal and vertical angles and slope distance

由 杀马特。学长 韩版系。学妹 提交于 2020-01-13 13:05:15
问题 I am trying to learn how to calculate the XYZ coordinates of a point using the XYZ coordinates of an origin point, a horizontal and vertical angle, and 3d distance. I can make the calculations simply by projecting the points onto 2D planes, but is there a more straightforward way to do this in 3D? I am trying to understand how a surveying total station calculates new point locations based on it's measured location, the 3d (slope) distance that it measures to a new point, and the measured

Unprojecting 2D Screen Coordinates to 3D Coordinates

由 ☆樱花仙子☆ 提交于 2020-01-12 08:52:30
问题 I was wondering how I would go about mapping 2D screen coordinates to a 3D world (specifically the xz plane) knowing: -position of the camera -equation of the screen plane -equation of the xz plane All I want to do is have the land on the xz plane light up when I hover the mouse over it. Any help is greatly appreciated! Thanks! 回答1: If your world is rotated and shifted such that the camera is at x=y=z=0 (world coordinates), the world z coordinate increases away from the viewer (into the

Invalid geo coordinates when searching for venues

由 别说谁变了你拦得住时间么 提交于 2020-01-11 12:34:09
问题 when searching for venues (intent "browse", southwest and northeast provided) I receive the following error: Invalid geo coordinates (0.400000,0.000000) What's wrong with these coordinates? I thought latitude is supposed to be in the range -90 to +90 and longitude in the range -180 to +180 ... Any help is appreciated! Thanks, Carl 回答1: This is intended behavior. The vast majority of cases where people send us 0.00 as a lat/long coordinate, it's because of some programming error/mistake, with

how to convert coordinates to geoPoint format?

问题 I am getting latitude and longitude coordinates in following format. <coordinates>N44 47.975 E20 17.052</coordinates> Can anyone guide me how to convert it to geoPoint format to display it on map? Any help would be appreciated. 回答1: The documentation explains everything: GeoPoint point = new GeoPoint((int)(47.975 * 1E6), (int)(17.056 * 1E6)) 来源： https://stackoverflow.com/questions/5701824/how-to-convert-coordinates-to-geopoint-format

How to move a marker 100 meters with coordinates

由 女生的网名这么多〃 提交于 2020-01-10 19:57:30
问题 I have 2 coordinates. Coordinate 1 is a 'person'. Coordinate 2 is a destination. How do I move coordinate 1 100 meters closer to coordinate 2? This would be used in a cron job, so only php and mysql included. For example: Person is at: 51.26667, 3.45417 Destination is: 51.575001, 4.83889 How would i calculate the new coordinates for Person to be 100 meters closer? 回答1: Use Haversine to calculate the difference between the two points in metres; then adjust the value of the person coordinates
