turf - A modular geospatial engine written in JavaScript

  •    Javascript

Turf is a JavaScript library for spatial analysis. It includes traditional spatial operations, helper functions for creating GeoJSON data, and data classification and statistics tools. Turf can be added to your website as a client-side plugin, or you can run Turf server-side with Node.js (see below).Download the minified file, and include it in a script tag. This will expose a global variable named turf.

uPlot - 📈 A small, fast chart for time series, lines, areas, ohlc & bars

  •    Javascript

μPlot is a fast, memory-efficient Canvas 2D-based chart for plotting time series, lines, areas, ohlc & bars; from a cold start it can create an interactive chart containing 150,000 data points in 135ms, scaling linearly at ~25,000 pts/ms. In addition to fast initial render, the zooming and cursor performance is by far the best of any similar charting lib; at ~35 KB, it's likely the smallest and fastest time series plotter that doesn't make use of context-limited WebGL shaders or WASM, both of which have much higher startup cost and code size. However, if you need 60fps performance with massive streaming datasets, uPlot can only get you so far. WebGL should still be the tool of choice for applications like realtime signal or waveform visualizations: See danchitnis/webgl-plot, huww98/TimeChart, epezent/implot, or commercial products like LightningChart®.

  •    JQuery

Gives ability to make accurate hover and clicks on transparent images. Only non-transparent pixels will trigger the hover / click event. This script is not only working with images, but also with background-images. If applied on an image it will use the src path, else it will test if data-img or background-image exists and use those instead.

flood-fill - A simple 2D JavaScript flood fill.

  •    Javascript

A simple 2D flood fill for use with ndarrays.You could use this to re-implement Microsoft Paint's bucket fill in JavaScript, or in procedural dungeon generation to identify disconnected rooms.

geojson-area - compute the area of a geojson polygon or multipolygon

  •    Javascript

Calculate the area inside of any GeoJSON geometry.Given a Geometry object, return contained area as square meters. Invalid input will return null.

worldpop - Get the population of regions that you draw!

  •    Javascript

Compute the population within a given polygon using the high resolution WorldPop population dataset. Go to http://devseed.com/worldpop and draw some polygons. The WorldPop Data Explorer is a web tool (and underlying Node module) designed to enable useful compuation and analysis using the WorldPop dataset. It makes heavy use of, among other things, Mapbox Vector Tiles, and Turf to enable efficient storage, access to, and computation over the otherwise prohibitively large WorldPop dataset.

leaflet-measure - Coordinate, linear, and area measure control for Leaflet maps

  •    Javascript

Coordinate, linear, and area measure control for Leaflet maps. Extends L.Control. leaflet-measure adds L.Control.Measure. This control may be used with the standard Leaflet control workflows described in the Leaflet docs.

postcss-pseudo-class-any-link - Use the :any-link pseudo-class in CSS
