PostGIS - Spatial and Geographic objects for PostgreSQL

•    C

---

PostGIS is a spatial database extender for PostgreSQL object-relational database. It adds support for geographic objects allowing location queries to be run in SQL. PostGIS adds extra types (geometry, geography, raster and others) to the PostgreSQL database. It also adds functions, operators, and index enhancements that apply to these spatial types.

GeoMesa - Suite of tools for working with big geo-spatial data in a distributed fashion

•    Scala

---

GeoMesa is an open-source, distributed, spatio-temporal database built on a number of distributed cloud data storage systems, including Accumulo, HBase, Cassandra, and Kafka. Leveraging a highly parallelized indexing strategy, GeoMesa aims to provide as much of the spatial querying and data manipulation to Accumulo as PostGIS does to Postgres.

magellan - Geo Spatial Data Analytics on Spark

•    Scala

---

Magellan is a distributed execution engine for geospatial analytics on big data. It is implemented on top of Apache Spark and deeply leverages modern database techniques like efficient data layout, code generation and query optimization in order to optimize geospatial queries. The application developer writes standard sql or data frame queries to evaluate geometric expressions while the execution engine takes care of efficiently laying data out in memory during query processing, picking the right query plan, optimizing the query execution with cheap and efficient spatial indices while presenting a declarative abstraction to the developer.

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.

activerecord-postgis-adapter - ActiveRecord connection adapter for PostGIS, based on postgresql and rgeo

•    Ruby

---

The activerecord-postgis-adapter provides access to features of the PostGIS geospatial database from ActiveRecord. It extends the standard postgresql adapter to provide support for the spatial data types and features added by the PostGIS extension. It uses the RGeo library to represent spatial data in Ruby. First, it provides spatial migrations. It extends the ActiveRecord migration syntax to support creating spatially-typed columns and spatial indexes. You can control the various PostGIS-provided attributes such as srid, dimension, and geographic vs geometric math.

BuntDB - Embeddable, in-memory key/value database for Go with custom indexing and geospatial support

•    Go

---

BuntDB is a low-level, in-memory, key/value store in pure Go. It persists to disk, is ACID compliant, and uses locking for multiple readers and a single writer. It supports custom indexes and geospatial data. It's ideal for projects that need a dependable database and favor speed over data size.The desire to create BuntDB stems from the need for a new embeddable database for Tile38 and SummitDB.

SpatiaLite - Spatial SQL

•    C

---

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.

esri2open - this repo is an ESRI toolbox and tool(s) that export ESRI Feature Classes to open data formats, CSV, JSON, and GeoJSON

•    Python

---

This repo is an ESRI toolbox and tool(s) that exports ESRI Feature Classes to open data formats, CSV, JSON, SQLite, and GeoJSON. Much of the data in government coffers is contained in spatial databases. A large percentage of government spatial data is created and managed using ESRI software. While the common interchange format, the ESRI Shapefile, is easily exported and imported by many other softwares, this data file format (the Shapefile) is not intrinsically part of the www ecology. Moreover, ESRI software does not provide an export of its generic 'feature class' (shapefile, file geodatabase, and personal geodatabase) to the most common open data file formats, CSV, JSON, and/or GeoJSON. Finally while open source tools easily transform ESRI shapefiles to open data, most government geospatial infrastructures only have ESRI tools. Lacking this basic export feature presented here, means the lion's share of government spatial data users cannot export their data to the most common open data formats.

node-gtfs - Import GTFS transit data into SQLite and query routes, stops, times, fares and more.

•    Javascript

---

node-GTFS loads transit data in GTFS format into a SQLite database and provides some methods to query for agencies, routes, stops, times, fares, calendars and other GTFS data. It also offers spatial queries to find nearby stops, routes and agencies and can convert stops and shapes to geoJSON format. Additionally, this library can export data from the SQLite database back into GTFS (csv) format.

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.

rtreego - an R-Tree library for Go

•    Go

---

A library for efficiently storing and querying spatial data in the Go programming language. The R-tree is a popular data structure for efficiently storing and querying spatial objects; one common use is implementing geospatial indexes in database management systems. Both bounding-box queries and k-nearest-neighbor queries are supported.

spatial4j - A Geospatial Library for Java

•    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.

Out of the box it exposes a Node.js server that can translate GeoJSON into the Geoservices specification supported by the ArcGIS family of products. Koop can be extended to translate data from any source to any API specification. Don't let API incompatiblity get in your way, start using one of Koop's data providers or write your own. Visit the demo at http://koop.dc.esri.com.

pgRouting - Extends the PostGIS / PostgreSQL geospatial database to provide geospatial routing functionality

•    C

---

pgRouting extends the PostGIS / PostgreSQL geospatial database to provide geospatial routing functionality. Data and attributes can be modified by many clients, like QGIS through JDBC, ODBC, or directly using Pl/pgSQL. The clients can either be PCs or mobile devices. Data changes can be reflected instantaneously through the routing engine. There is no need for precalculation. The “cost” parameter can be dynamically calculated through SQL and its value can come from multiple fields or tables.

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).
