<h3>OpenSextant</h3>

<p>The Open Spatial Extraction and Tagging (OpenSextant) software provides an unstructured textual data geotagging and geocoding capability. The U.S. Government Joint Improvised Explosive Device Defeat Organization (JIEDDO) developed this capability in coordination with other U.S. government agencies and is pleased to provide this as open source software using an Apache 2.0 license. The software relies upon the open source General Architecture for Text Engineering (GATE) natural language processing software and the Apache Solr search software. Please see below for instructions on how to access the source code and binaries.
OpenSextant Suite</p>

<p>This suite is various projects for geospatial and temporal extraction. The core module is OpenSextantToolbox which produces a GATE plugin and a toolkit for controlling the overall extraction and geocoding pipeline using that plugin.</p>

</li>
</ul>
<h3>Peer Projects</h3>
