GeoNames in DAML

Home | About DAML | Announcements | Roadmap | Site Search

This page describes a DAML+OIL (March 2001) representation of information provided by the GEONet Names Server (GNS) from the U.S. National Imagery and Mapping Agency (NIMA). GNS includes information on about 3.84 million features and 5.28 million names worldwide, exluding the United States and Antarctica.



We downloaded the tab-delimited names files for each country. We initially tried to generate a static .daml file for each feature and country, but the data volume proved prohibitive. We now load the data into a mySQL and dynamically generate DAML content dynamically.

Based on the names file format we manually created

We used a custom program gendaml.java to generate featureTypes.daml from the GNS Feature Designation Cross Reference.

We developed a CGI program geonames.java to access the database and produce DAML for each country, feature, or name on demand.

Notable features include:
