geojson-vt - Slice GeoJSON into vector tiles on the fly in the browser


A highly efficient JavaScript library for slicing GeoJSON data into vector tiles on the fly, primarily designed to enable rendering and interacting with large geospatial datasets on the browser side (without a server).Created to power GeoJSON in Mapbox GL JS, but can be useful in other visualization platforms like Leaflet and d3, as well as Node.js server applications.

rbush - RBush — a high-performance JavaScript R-tree-based 2D spatial index for points and rectangles


RBush is a high-performance JavaScript library for 2D spatial indexing of points and rectangles. It's based on an optimized R-tree data structure with bulk insertion support. Spatial index is a special data structure for points and rectangles that allows you to perform queries like "all items within this bounding box" very efficiently (e.g. hundreds of times faster than looping over all items). It's most commonly used in maps and data visualizations.

Mapsforge - Vector map library written in Java - running on Android and Desktop.


Mapsforge project uses a compact file format for fast ad-hoc rendering of OpenStreetMap data. It provides tools to compile your own maps with detailed instructions and also precompiled maps, Simple boilerplate code to build applications for Android that display OpenStreetMap-based maps. Mapsforge maps can be flexibly styled with XML style files (render themes).




leaflet - R Interface to Leaflet Maps


Leaflet is an open-source JavaScript library for interactive maps. This R package makes it easy to create Leaflet maps from R. In addition to the usual R package documentation, we also have extensive docs and examples at: http://rstudio.github.io/leaflet You may use Github issues to file bug reports or feature requests, and ask questions on StackOverflow or in the Shiny mailing list.

DotSpatial


DotSpatial is an open source project focused on developing a core set of GIS and mapping libraries that live together harmoniously in the DotSpatial namespace working seamlessly with the .NET framework.

spatial4j - A Geospatial Library for Java


Spatial4j is a general purpose spatial / geospatial ASL licensed open-source Java library. It's core capabilities are 3-fold: to provide common geospatially-aware shapes, to provide distance calculations and other math, and to read shape formats like WKT and GeoJSON.

SpatiaLite - Spatial SQL


SpatiaLite is an open source library intended to extend the SQLite core to support fully fledged Spatial SQL capabilities. SQLite is intrinsically simple and lightweight, It is a single lightweight library implementing the full SQL engine. SpatiaLite is smoothly integrated into SQLite to provide a complete and powerful Spatial DBMS (mostly OGC-SFS compliant). Using SQLite + SpatiaLite you can effectively deploy an alternative open source Spatial DBMS roughly equivalent to PostgreSQL + PostGIS.


GeoCouch - A spatial index for CouchDB


GeoCouch is a spatial extension for Couchbase and Apache CouchDB.This version of GeoCouch needs at least Apache CouchDB 1.3.x.

JCS - Conflates spatial datasets


The JCS Conflation Suite is an API and set of interactive tools which perform conflation on spatial datasets.

Spatial Solr Plugin for Lucene and Solr


With the continuous efforts of adjusting search results to focused target audieces, there's an increasing demand for incorporating geographical location information into the standard search functionality. Spatial Solr Plugin (SSP) is a free, standalone plug-in which enables Geo / Location Based Search, and is built on top of the open source projects Apache Solr and Apache Lucene.

sf - Simple Features for R


this will install binary packages on Windows and MacOS, unless you configured R such that it tries to install source packages; in that case, see below. Installing sf from source works under windows when Rtools is installed. This downloads the system requirements from rwinlib.

flatbush - A very fast static spatial index for 2D points and rectangles in JavaScript


A really fast static spatial index for 2D points and rectangles in JavaScript. An efficient implementation of the packed Hilbert R-tree algorithm. Enables fast spatial queries on a very large number of objects (e.g. millions), which is very useful in maps, data visualizations and computational geometry algorithms.
