turf VS proj4js

to measure distances and convert between our parameters I'm using TurfJS, for which binding is even more trivial:

Turf.js is an open-source geospatial analysis library that can process various location data, such as the center of gravity and distance calculations.

Isochrones are manually calculated using turf.js assuming 1.2m/s walking speed after the subway trip. These are simple buffers around each station/prior isochrone and do not take the street network into account.

Not to take away from you learning, which I think is awesome, I was wondering if you know about http://turfjs.org/ which provides a lot of simple modules … and is surprisingly hard to find. Their `distance` modules may be relevant in this case.

you can use client side libraries like Turfjs to do buffers https://github.com/Turfjs/turf/tree/master/packages/turf-buffer

Tools: custom Javascript (with heavy use of turf.js) for data processing and creating the 3D model, Blender, 3D printing, lost wax casting

I've integrated https://turfjs.org/ with mapbox before and it was pretty fun

It is needed to link the required JS scripts in the section of the HTML page. These scripts include the Core and Geo Maps modules and the file that contains geodata for the world map, all of which are available on the CDN. I'll also use two more script files to connect the data to the choropleth map. One is the Data Adapter, which will help load the data, and the other is Proj4js, a JavaScript library that will transform the coordinates from one coordinate system to another so the data can be plotted on the map accurately.

E.G. if I wanted to use proj4js apart from copying the entire build file into my source code, there is no easy way for me to use this library. I.E. code reuse is a nightmare still.

We need the Core and Geo Map modules to take care of data visualization in the form of a connector map, geodata for a world map, and the Proj4js library to take care of geographic coordinates.

One more script to wrap up the map-related additions is Proj4js, a JavaScript library that ensures the plotting of coordinates over the appropriate geographical area.

In addition, I will make use of another JavaScript library — Proj4js — which, in short, takes care of plotting the coordinates over the respective geographical areas.

In this way we can also still use javascript libraries to do complex tasks. E.G. Projection which is far too complicated to do in PowerAutomate. I've had this use case when trying to go from Latitude Longitude coords created by a phone to British National Grid coordinate system.

Was hoping to make a mosaic of tiles. I used poj4js to convert data points, but it turned out to be very inaccurate for the moon (like off by 20 degrees or more).

Then see in the doc here : https://github.com/proj4js/proj4js how to convert, it's easy once you have the definition.
