Topographic mapping data semantics through data conversion and enhancement: Chapter 7
This paper presents research on the semantics of topographic data for triples and ontologies to blend the capabilities of the Semantic Web and The National Map of the U.S. Geological Survey. Automated conversion of relational topographic data of several geographic sample areas to the triple data model standard resulted in relatively poor semantic...Edited by Ashish, Naveen; Sheth, Amit P.; Varanka, Dalia; Carter, Jonathan; Usery, E.

US Topo - A new national map series
In the second half of the 20th century, the foundation of the U.S. Geological Survey's national map series was the handcrafted 7.5-minute topographic map. Times change, budgets get squeezed and currency expectations become ever more challenging. The USGS's Larry Moore, who oversees data production operations at two National Geospatial Technical...Moore, Laurence R.

An analysis of spatial relation predicates in U.S. Geological Survey feature definitions
The Semantic Web uses a data model called a triple, which consists of a subject -predicate - object structure. When represented as triples, geospatial data require a spatial relation term to serve as the predicate linking two spatial features. This document summarizes the approaches and procedures used during the identification of spatial...Caro, Holly K.; Varanka, Dalia E.
A program for the conversion of The National Map data from proprietary format to resource description framework (RDF)
To expand data functionality and capabilities for users of The National Map of the U.S. Geological Survey, data sets for six watersheds and three urban areas were converted from the Best Practices vector data model formats to Semantic Web data formats. This report describes and documents the conver-sion process. The report begins with an...Bulen, Andrew; Carter, Jonathan J.; Varanka, Dalia E.

Phase One of the OpenStreetMap Collaborative Prototype (OSMCP) attempts to determine if the open source software developed for the OpenStreetMap (OSM, http://www.openstreetmap.org) can be used for data contributions and improvements that meet or exceed the requirements for integration into The National Map (http://www.nationalmap.gov)....Wolf, Eric B.; Matthews, Greg D.; McNinch, Kevin; Poore, Barbara S.
Ontology patterns for complex topographic feature yypes
Complex feature types are defined as integrated relations between basic features for a shared meaning or concept. The shared semantic concept is difficult to define in commonly used geographic information systems (GIS) and remote sensing technologies. The role of spatial relations between complex feature parts was recognized in early GIS...Varanka, Dalia E.
A 125 year history of topographic mapping and GIS in the U.S. Geological Survey 1884-2009, part 1: 1884-1980
