Benjamin Sigrist, Salisbury University Julius Pasay, Wesleyan University Timothy Joyner, Louisiana State University Justin VanderBerg, Michigan State University Matthew Bampton, University of Southern Maine Mark Swanson, University of Southern Maine A Data Model for Human Ecology Developed on Damariscove Island, Maine
In Brief • Problem: field research environment with large data burden • Solution: data model developed to standardize, make accessible, streamline data process • Application: case studies utilizing the data model
Background • NSF Research Experience for Undergraduate Program since 2000 • Geologic and human ecology research conducted on southern coast of Maine • Diverse data sources/collection methods • Large amount of digital data
The Challenge • Limited time frame for research • Data management is a low priority for field workers • Lack of continuity between annually rotating teams • Due to lack of management, data is inaccessible and underutilized • Need for cyberinfrastructure • Data model has been developed and implemented to manage data
Human Ecology • Requires diverse data sets to explore human interaction with landscapes • Historic maps • Photographic records • Aerial images • Documentary records • Botanical survey • Elevation data • Bathymetric data • Tree coring samples • Land use data
Data Model • Developed with the following in mind • North American Geologic Map Data Model • FGDC • OGC • Goal is to manage data more efficiently, while making it accessible and standard • Consists of three parts (NADM) • Geologic Concept • Geologic Representation (standard ontologies) • Metadata • Designed to be technology neutral to facilitate data sharing
Metadata • Essential, but frequently neglected • Began as a paper system • Three types of cards • Datum • Raw data • Process • Moved to digital system using Microsoft Access
Spatial Data • Data was organized by field location • Standard file nomenclature developed • Transferred to ESRI geodatabase as a beta test • So did it work?
Environmental Case Study • The Human Ecology project explored the history of land-use on Damariscove over four centuries • Wide variety of data collected to analyze • Human structures • Topography • Vegetation • Soils • Landuse • Result: Much more complete knowledge of human interactions with the environment on Damariscove
Glaciation Case Study • This study explored the effects of glaciation on Damariscove Island • Data used: • DEM/Bathymetry from MEGIS and NOAA • Glacial striation field measurements taken with GeoXT • TIN/slope/aspect developed • Result: Alternative regional glacial reconstruction model
Conclusions • Data model developed • Data managed more efficiently • Can be used and built upon by future teams • Model is flexible and can incorporate a wide variety of data sources and formats as illustrated by case studies
Future Work • Data sharing via a data portal • Integrating a more robust spatial database
