Origins of NatureMapping IDAHO
Citizen Science • Value of Citizen Science • Basic Skills • Education Resources • Stewardship Plans
Wisconsin NatureMapping Beaver Creek Reserve • Observe • Record • Resources connecting people with nature

Existing Site - New Site • Arc IMS • New Studies • Mapping Tools • Usability Study
Open Source Technologies • GoogleMaps: Base Map Layers • GeoServer: Wildlife sightings layer that interfaces with… • PostGIS extension Spatial data • PostgreSQL: Database
GeoServer’s Job is to Answer Questions -”Talk” to GeoServer over a network. (HTTP) - Ask GeoServer about spatial data that it can read (Shapefiles, PostGIS, ArcSDE, Oracle, etc.) …in a language it understands, (WFS, WMS, WCS) …and it will answer in pictures (JPEG, PNG, GIF, PDF) …or in words (WFS, KML/KMZ, GML). • Details – Maintainer: The Open Planning Project (http://www.openplans.org) – Web Site: http://geoserver.org/ – Implementation Language: Java – Source License: GPL
System Component: Data Storage • Purpose – stores attribute, geometry and projection information – performs spatial calculations (i.e. intersect, buffer) Examples – ESRI ArcSDE + relational database • proprietary + proprietary, limited spatial functions – Oracle Spatial • proprietary, rich set of spatial functions – MySQL • open source, basic geometry storage – PostGIS • open source extension to the PostgreSQL database • implements OGC spatial functions
PostGIS + PostgreSQL • Function – Vector data storage – Spatially-enabled relational database • Compare to: – ESRI ArcSDE + SQLServer (or other RDBMS) – Oracle Spatial • Composed of: – PostgreSQL (OS relational database) – PostGIS (OS spatial extension) • Details – Maintainer: Refractions Research Inc – Web Site: http://postgis.refractions.net – Implementation Language: C – Source License: GPL
REASONS FOR SWITCHING TO OPEN SOURCE TECHNOLGIES • Cost savings for organizations that are dependent on grants • Intuitiveness • Base Layer Maps/Road Layers • Adaptability to changes and updates
