  • proj4js

    JavaScript library to transform coordinates from one coordinate system to another, including datum transformations

    • Project mention: How to Build a Choropleth Map in JavaScript | dev.to | 2023-05-26

    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.

  • geojson.io

    A quick, simple tool for creating, viewing, and sharing spatial data

  • h3-js

    h3-js provides a JavaScript version of H3, a hexagon-based geospatial indexing system.

  • koop

    Transform, query, and download geospatial data on the web.

  • WorkOS

  • OpenRailwayMap

    An OpenStreetMap-based project for creating a map of the world's railway infrastructure.

    • Project mention: Waterway Map | news.ycombinator.com | 2024-01-24

    Looks nice but it's probably not really usable for navigation. I checked the Netherlands and Germany. You'd need more details for safely navigating on the water. But it definitely has potential.

    There are also some other specialized open street map based maps for

    - rails: https://www.openrailwaymap.org/

    - cycling: https://www.opencyclemap.org/

    - sea map (competes with this I guess, and is a bit more detailed for navigation): https://map.openseamap.org/

    And probably loads of other ones.

  • gdal3.js

    Convert raster and vector geospatial data to various formats and coordinate systems entirely in the browser.

  • analytics-toolbox-core

  • edinburghjs-meetup-walktimedemo

    A simple web app demonstrating how to calculate areas within a 15 min walking distance from a location, built with the ArcGIS Maps SDK for Javascript.

    • Project mention: Journey into Javascript: My First-time Speaking Experience at a Tech Meetup | dev.to | 2024-01-15

    I had an idea in mind - when I'm working from the office, I want to understand where is most efficient to meet a friend coming from the other side of the city within a lunch break. I therefore wanted to build a simple geospatial application (find the code for this on my GitHub) that could calculate walk times from each of our locations, and show the area of overlap that we could both reach within that walk time.
