kandi X-RAY | Haversine Summary

Haversine is a PHP library. Haversine has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

For the winners are selected based on being closest to a random point on the globe. The equation used to compute the distance is the Haversine formula. In full disclosure, the code used to compute the distance has been open sourced. To use this in your own projects, you simply include the file include('haversine.php');. And pass it a pair of lat/lons $distance = haversine($lat1,$lon1,$lat2,$lon2);. The distance in kilometers is returned.

Error from calculating the distance between points with latitiude and longitude in python

Asked 2021-Jun-10 at 00:31

I am trying to calculate the distance (in km) between different geolocations with latitude and longitude. I tried to use the code from this thread: Pandas Latitude-Longitude to distance between successive rows. However, I run into this error:

You're passing in a Series to the haversine function rather than a simple number for the lat and lon attributes.

I think you can use the apply function to apply the haversine to each row in the dataframe, however, I'm not too sure what the best way is for apply to be able to get hold of the next or previous row.

So, I'd just add a couple of extra columns 'from lat' and 'from lon'. Then you will have all the data you need on each row.

Creating a dataframe of many loops within loops for haversine geolocation

Asked 2021-May-31 at 22:04

I have a df with 3 people ("members") and I would like to measure the distance of these people from 3 locations. The end result would be a df ranking the 3 locations from closest to farther for all 3 people. I have the geocoordinates for all 3 people and all 3 locations and this is what I've tried so far but I don't know how to finish the loop to concatenate the frames to a master frame. Please help!:

Cross merge to associate all rows in members with all others in locations, use haversine_vector to calculate distances, sort_values to order from closest to farthest, then pivot_table to go from long to wide format, lastly collapse the MultiIndex:

QUESTION

Why is my recursive function not using an updated state value?

Asked 2021-May-26 at 04:36

I am trying to continually check if the current location of the user is within 100 meters of markers placed on a map.

I do this with a recursive function that checks all markers against current location with the haversine formula. When the recursive checkMarkers() function is first called, the array markers is empty.

With log statements I can see that the recursive function is still running, but when the state of markers changes, it is not reflected in checkMarkers().

...

ANSWER

Answered 2021-May-26 at 04:24

It looks like you are wanting to log the state/haversine values once every second. Use a mounting useEffect hook to initiate an interval to call the checkMarkers callback and remember to return a cleanup function. Use a ref and additional useEffect hook to save a reference to the current state for use in the interval callback.

Faster approach to finding distance between coordinates

Asked 2021-May-19 at 22:58

I have a list of places and I need to find the distance between each of those. Can anyone suggest a faster method? There are about 10k unique places, the method I'm using creates a 10k X 10k matrix and I'm running out of memory. I'm using 15GB RAM.

Answered 2021-May-19 at 22:58

If you want to resolve your memory problem you need to use datatypes that use less memory. In this case since the maximum distance between two points on the planet Earth is less than 20005Km you can use uint16 to store the value (if a 1Km resolution is enough for you)

Since i hadn't any data to work with i generated some data with the following code:

ANSWER

Answered 2021-May-03 at 15:36

I think it might be easier to just use your city_data without breaking it into separate lists.

I like list comprehensions so I am going to use one to cross product the list of cities with itself and calculate the distance between them. Then we will print only the pairs that are nearby each other.

There are likely some optimizations to be had for example, if you know the distance from "A" to "B" then you might not need to calculate the distance form "B" to "A". I leave that to you to think about.

The code you are using to calculate haversine distance receives one float in each argument, so indeed you need to pass floats for each argument. In this case iskeleler['lon'] and iskeleler['lat'] are Series.

This should work to calculate the distance between coordinates in the same row:

Install Haversine

You can download it from GitHub.
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
