Calculate distance between multiple latitude and longitude points

Asked 2022-Mar-31 at 23:43

I have a dataset that has latitude and longitude information for participants' home and work, and I'd like to create a new column in the dataset containing the euclidean distance between home and work for each participant. I think this should be relatively simple, but all the other Q&As I've seen seem to be dealing with slightly different issues.

To start, I tried running this code (using the geosphere package):

You can have the latitudes and longitudes in a dataframe and then do rowwise operations on the dataframe to get the distance corresponding to each row.

Your shiny example as three inputs:

Slider, which gets passed to k in the function signature
Filter1, which appears to be the same as k (i.e. choosing a cluster), and currently gets passed to Filter1 in the function signature
Filter2, which is for selecting the Property, but never gets passed to the function.

I think what you want to do is include only Slider and Filter2 (or Filter1 and Filter2).

Then change the Modelcl to

Dealing with Lists in R - combine two data frames and calculate values with mismatched sizes

Asked 2022-Mar-19 at 16:40

I have two data.frame in R that I need to calculate values based on a subset of columns in each of the two dataframes.

This is geolocated data, so I've been using geosphere to do some of the calculations. These are the two dataframes. dat1 contains just a list of lat/long coordinates for random data points on the surface of the Earth. dat2 is a set of objects on Earth with a lat/long location and a speed/size associated with them.

ANSWER

Answered 2022-Mar-19 at 12:23

You can create a new dataframe that creates all combinations of points in dat1 and dat2 with tidyr::crossing and then call the distGeo function on the resulting dataframe.

I created an error alert for when a file of format other than ".xlsx" is loaded in fileInput. For that I created sendSweetAlert. This is working. What I would like now is the following: Whenever I load a ".xlsx" file, apparently the code does not give any error, however I would like to accept only ".xlsx" files, which are actually usable by my function.

The file I use can be downloaded from this link: encurtador.com.br/dqsOQ

Show the property number and not the cluster number on a map made in shiny

Asked 2022-Mar-10 at 21:41

I have a shiny code that generates clusters of properties and as you can see below, it is displayed on the map made in leaflet. If I place the mouse cursor on the properties, the number of the corresponding cluster appears, but what I wanted was for it to show which property number it is. For example, it is 1, 2, 3, 4, 5, 6 or 7? Can you help me to resolve this?

Calculating distance between coordinates and reference point

Asked 2021-Dec-02 at 12:16

I want to calculate the distance between lat1, lon1 and a reference point (52.92343, 5.04127). I want to this for every row in my dataset, so the distance will be calculated with the reference in every row. That means I will create a new column with the distance in km. I can imagine you will have to use some kind of loop function, but so far I have not figured out how to accomplish this. I think I will have to use the packages geodist or geosphere, but unfortunately was not successful. How can I calculate these distances?

...

ANSWER

Answered 2021-Dec-01 at 17:34

No need to loop, you can just calculate the distance between entries in an array of coordinates in x and a single point in y using geodist. Just passing in the coordinates as lon/lat explicitly and saving back as a numeric vector to Distance rather than as the original matrix output.

QUESTION

Is distm() with distHaversine giving inaccurate results?

Asked 2021-Oct-19 at 19:15

I'm confused by this result I'm getting from geosphere::distm(). I compute the distance from a starting point to two points a and b. On Google Maps, I can see that the distance from start to a is greater than the distance from start to b. But the distm() function makes it appear that the reverse is true.

...

ANSWER

Answered 2021-Oct-19 at 18:38

This looks like a situation of swapping latitude and longitude. (I do this every time.) While the traditional way to communicate a coordinate is Lat,Long, distm is looking for Long,Lat (ie relating to XY). We can swap the order using rev to reverse the order of the coordinate vector.

Geocoding: Efficient way to find the distance between two sets of locations

Asked 2021-Sep-28 at 05:32

I have a set of coordinates of the locations of different individuals, and another set of coordinates of different drop off boxes, for their ballots. I'm trying to find the distance between their residence, and the nearest dropbox. I've attached a copy of the code I have to work through that as of now--it was replicated from another stack overflow example. However, it is not too efficient, as the dataset I'm working with is millions of rows, and the code relies on finding all possible combinations of coordinates, and then pulling the least distance. Is there a more efficient way to deal with this?

What I currently have:

...

ANSWER

Answered 2021-Sep-28 at 05:32

The sf package makes this simple. The st_as_sf() function converts data frame of lat-long values to georeferenced points, and the st_distance() function calculates the distances between them. When running st_as_sf(), you'll need to specify a coordinate reference system. It looks like you're using latitude and longitude, so I specify crs="epsg:4326", which is the most common latitude/longitude reference.

You can use the following solution. You have to swap mean_lon and mean_lat columns in your second data frame as you will get an error while lon and lat are exchanged.
