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.

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.

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.

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.

Whitebox Geospatial Analysis Tools - An open-source GIS and remote sensing package

•    Java

---

Whitebox GAT is an open-source geographical information system (GIS) and remote sensing package. The Whitebox GAT project began in 2009 and was conceived as a replacement for the Terrain Analysis System (TAS). Whitebox GAT is intended to provide a platform for advanced geospatial data analysis with applications in both environmental research and the geomatics industry more broadly.

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.
