equirect-to-cubemap-faces - Convert an equirectangular image (aka lat-long map) into cubemap faces you can feed to WebGL

  •        112

Function that convert an equirectangular/latlong map into an array of cubemap faces (like you would use to send to OpenGL). Works in the browser or as a commonjs module. Provides a single function equirectToCubemapFaces(image, faceSize, options). The face size is optional, and defaults to the nearest power of two to image.width/4 (this is totally arbitrary). The image argument can be an img element, a canvas, or an ImageData.

jgeohash - An easy-to-implement library for the GeoHash algorithm

  •    Java

An easy-to-implement library that can assist Java developers in using the GeoHash algorithm in order to create geocodes based on custom latitude and longitude values. With the help of jGeohash, Java developers will be able to quickly and easily generate a geohash code using user-defined latitude and longitude values. By using the GeoHash algorithm, the space can be divided into multiple grid shapes.


Geolib - Growing library to provide some basic geo functions

  •    Javascript

Library to provide basic geospatial operations like distance calculation, conversion of decimal coordinates to sexagesimal and vice versa, etc. Takes 2 or 4 arguments. First 2 arguments must be objects that each have latitude and longitude properties (e.g. {latitude: 52.518611, longitude: 13.408056}). Coordinates can be in sexagesimal or decimal format. 3rd argument is accuracy (in meters). So a calculated distance of 1248 meters with an accuracy of 100 is returned as 1200 (accuracy 10 = 1250 etc.). 4th argument is precision in sub-meters (1 is meter presicion, 2 is decimeters, 3 is centimeters, etc).

Pelias - Modular open-source geocoder using ElasticSearch

Geocoding is the process of taking input text, such as an address or the name of a place, and returning a latitude/longitude location on the Earth's surface for that place. Reverse geocoding is the opposite, returning a list of places near a given latitude/longitude point. It supports many open-data projects out of the box but also works great with private data. It supports searching and displaying results in many languages.

In addition to storing and retrieving numeric and alphanumeric data, the ThingSpeak API allows for numeric data processing such as timescaling, averaging, median, summing, and rounding. Each ThingSpeak Channel supports data entries of up to 8 data fields, latitude, longitude, elevation, and status. The channel feeds support JSON, XML, and CSV formats for integration into applications.

nyc-taxi-data - Import public NYC taxi and Uber trip data into PostgreSQL / PostGIS database, analyze with R

  •    R

This repo provides scripts to download, process, and analyze data for over 1.8 billion taxi and for-hire vehicle (Uber, Lyft, etc.) trips originating in New York City since 2009. The data is stored in a PostgreSQL database, and uses PostGIS for spatial calculations, in particular mapping latitude/longitude coordinates to census tracts. Most of the raw data comes from the NYC Taxi & Limousine Commission. The 2014 Uber data comes via FiveThirtyEight, who obtained it via a FOIL request. In August 2016, the TLC began providing for-hire vehicle trip records in addition to taxi trips.
