We are proud to be an active part of the Open Source community as both a contributor and a consumer, and utilize a number of Open Source libraries to support connecting to 1800+ different file formats. Voyager builds upon Lucene, the most advanced and widely used open source search engine available today. Apache SOLR provides a blazingly fast search service on top of Lucene and is at the heart of the Voyager platform.
Framework for extracting text from a huge number of file formats and content management systems
Provide the engine that allows Voyager to extract a rich amount of spatial information from files being indexed, and, for a reliable and scalable indexing pipeline, Voyager utilizes the tried and true ZeroMQ library for messaging and distributed processing.
Our Open Source geotagger is called Opensextant, and our maps are based on Leaflet.
The processing framework in Voyager is built on the Python language and utilizes a number of great open source libraries, such as GDAL and OGR, to deliver content to users.
We also support open standards like OGC and FGDC, as well as many ISO standards. And, when we store spatial info, Voyager can return it as GeoJSON.
Our online demo is an open data portal. Visitors can search
publicly available geospatial information, do keyword-related and wildcard
searches, discover data, download it, transform it, and more.
Developer and Software Resources
We release as much code as possible so that users can customize instances and build upon our COTS. Visit Voyager on GitHub.
