GeoWave is an open source set of software that:

  • Capabilities
  • Geospatial software plugins
    • GeoServer plugin to allow geospatial data in various key/value stores to be shared and visualized via OGC standard services

Basically, GeoWave is working to bridge geospatial software with modern key/value stores and distributed compute systems.

The Docs

The Software

  • We have multi-platform standalone installers for the GeoWave's command-line tools to help get started
    • This is often the quickest and easiest way to get started using GeoWave on your own machine
  • We have a RPM repository
    • This contains various packages including puppet modules, best used for distributed environments.
    • See the Installation Guide for more info.
  • Maven artifacts are available on Maven Central
  • And you can always build from source

Getting Started

Programmatic Access

You can use Maven to reference pre-built GeoWave artifacts with the following pom.xml snippet (replacing ${keyvalue-datastore} with your data store of choice and ${geowave.version} with the GeoWave version you'd like to use):

	<dependencies>
		<dependency>
			<groupId>org.locationtech.geowave</groupId>
			<artifactId>geowave-datastore-${keyvalue-datastore}</artifactId>
			<version>${geowave.version}</version>
		</dependency>
		<dependency>
			<groupId>org.locationtech.geowave</groupId>
			<artifactId>geowave-adapter-vector</artifactId>
			<version>${geowave.version}</version>
		</dependency>
		<dependency>
			<groupId>org.locationtech.geowave</groupId>
			<artifactId>geowave-adapter-raster</artifactId>
			<version>${geowave.version}</version>
		</dependency>
	</dependencies>

Use the libraries available in the api package to leverage GeoWave's capabilities (where <data store options> might be AccumuloRequiredOptions or HBaseRequiredOptions and simple examples of creating the data type and index can be found in SimpleIngest within the examples directory):

DataStore store = DataStoreFactory.createDataStore(<data store options>);
store.addType(<my data type>, <my index>);
try(Writer writer = store.createWriter()){
  //write data
  writer.writer(<data>);
}
 
//this just queries everything
try(CloseableIterator it = store.query(QueryBuilder.newBuilder().build())){
  while(it.hasNext()){
    //retrieve results matching query criteria and do something
    it.next();
  }
}

See the Developer Guide for more detailed programmatic API examples.

Command-line Access

Alternatively, you can always use the GeoWave command-line to access the same capabilities:

# Add a new RocksDB data store called myStore in the current directory
geowave store add -t rocksdb myStore

# Add a spatial index called spatialIdx to myStore
geowave index add -t spatial myStore spatialIdx

# Ingest a shapefile with states into myStore in the spatialIdx index
geowave ingest localToGW -f geotools-vector states.shp myStore spatialIdx

# Query all the data in the states type from myStore
geowave vector query "SELECT * FROM myStore.states"

See the CLI documentation for a full list of commands and their options.

Supported versions of core libraries

We work to maintain a N and N-1 tested and supported version pace for the following core libraries.

GeoServer GeoTools Accumulo HBase Hadoop Java
2.19.x 25.x [1.9.x,2.0.x] 2.4.x [2.10.x,3.1.x] Java8

Origin

GeoWave was originally developed at the National Geospatial-Intelligence Agency (NGA) in collaboration with RadiantBlue Technologies (now Maxar Technologies) and Booz Allen Hamilton. The software use, modification, and distribution rights are stipulated within the Apache 2.0 license.
