Find boundary points of xy coordinates

I have a text file with xy-coordinates called xy.txt. I read the file using and I can plot the points with Visually the data looks as follows: I want to retrieve the xy-coordinates of the points that form the boundary of the shape. Answers on similar questions suggest to use Concave Hull. With the help of this blog I write

1D netcdf to 2D lat lon using xarray and Dask

I have a large netcdf dataset which has two dimensions – ‘time’ and a single spatial dimension ‘x’. There is also a ‘lat’ and ‘lon’ coord for each ‘x’. This needs to be mapped onto a global half degree 2D grid, such that the dimensions are ‘time’, ‘lat and ‘lon’. Not all the points on the global half degree grid

Python + Minecraft Coordinates Trouble

The Y coordinate listed below teleports you to double what it’s supposed to ingame. It is supposed to teleport you to 0, 62, 0, but it teleports you to 0, 124, 0 Answer Per comments on the documentation for mcpi, it would appear that the coordinates are relative to the world spawn: getPos, getTilePos, setPos and setTilePos all appear to

Removing the 2d point that are close to each others

I would like to remove the coordinates that lie close to each other or if it is just a duplicate. For example, In the above list, the first and second element lies close to each other. How do I remove the second element while preserving the first one? Following is what I have tried, The problem is that it doesn’t

How to iterate through neighbours in 2D coordinates?

In a 2D plane, I want to check the neighbouring points until meeting a condition. For example, take a red pixel in this image (x,y). I want to iterate to find the white pixel closest to the selected red pixel. This is an updated image provided by @Pranav Hosangadi My original code is now irrelevant. A possible solution is to

Python, convert coordinate degrees to decimal points

I have a list of latitude and longitude as follows: I need to convert it to floats [33.0595, -101.0528]. Sure, the ‘-‘ is the only difference, but it changes when changing hemispheres, which is why a library would be ideal, but I can’t find one. Answer You can wrap the following code in a function and use it: The result

degree decimal to utm conversion, python

I got surprised when I tried to convert degree decimal coordinates into utm by using available library in anacondautm. my coordinates looks like: and lat values are: when I made scatter plot it looks like normal: After converting coordinates in to utm distribution of the points change completely and looks strange like in this figure: the code that i used
