问题 I've uploaded .SHP files to my table in sql and I got geometry column with data. I can see points on "Spatial results" tab in sql server and that's all fine. When I run this line in sql server SELECT [geom].STAsText() FROM myTable I get these kind of results POINT (444386.4927124856 5073381.9183241855) So is there any way to convert this to regular latitude and longitude. 来源： https://stackoverflow.com/questions/22611331/converting-geometryspatial-to-longitude-and-latitude

How to find a set of lat/long pairs surrounding a 5 miles radius of a certain location

问题 How to find a set of lat/long pairs surrounding a 5 miles radius of a certain location expressed in lat/long or as a address. 回答1: First you decide how many (lat,lon) pairs you want to have: You could want to have 4 cordinates forming a square arround the center point. Or you decide to have a regualr N-Gon around the center point. Then you use a projection from lat/lon to meters, e.g EquiDistantProjetion. This allows you to transform the lat/lon center to cartesian meters, where you then can

Efficient way to get index of minimum value in long vector, python

由 若如初见. 提交于 2019-12-12 10:35:11
问题 I have a long list of longitude values (len(Lon) = 420481), and another one of latitude values. I want to find the corresponding latitude to the minimum of the longitude. I tried: SE_Lat = [Lat[x] for x,y in enumerate(Lon) if y == min(Lon)] but this takes ages to finish. Does anyone know a more efficient way? Maybe you also have a suggestions for this: I now try to find the closest corresponding latitude to a new longitude, which is not in the original longitude vector. I tried this: minDiff

I know how to calculate the distance, I don't know how to sort them. 回答1: get the CLLocation for your currentPosition (this is
