The GIS-studio was established in 2003 to serve students and staff of the Institute for Biodiversity and Ecosystem Dynamics (IBED) of the University of Amsterdam and to assist them in their spatial data analysis using Geographical Information Systems (GIS) and remote sensing software.
The GIS-studio is equipped with 18 high-end computers (64-bit quad-core processors, dual widescreen monitor setup, 8GB RAM, Win7) and up-to-date GIS and remote sensing software, such as ArcGIS 10, Erdas Imagine 2010 and eCogntion Developer 8.7.
Detailed information about the GIS-studio, including examples of its use in IBED research, can be found on the website of the IBED GIS-studio.
The Global Positioning System (GPS) is a constellation of 24 satellites which circumnavigate our planet. GPS consist of a space segment (satellite), a control segment (ground station) and the user segment GPS receivers. Special GPS facilities and hand-held data acquisition units are available for use by IBED staff members and students during their field-based research.
A Differential GPS (DGPS) station enhances the signal provided by the GPS space segment and allows positioning with centimetre accuracy which can be used to produce high-resolution elevations models of a field work site or the very precise location of e.g. sample point. We operate the Topcon HiPer+ system which has a dual-constellation (GPS + GLONASS) capability and an excellent under-canopy performance for use in e.g. densely forested areas.
Mobile GIS is an expansion of a traditional Geographic Information System from the office into the field. It integrates four key technologies: the Global Positioning System, a hand-held unit which combines a GPS receiver with a field computer (Trimble GeoExplorer), GIS software and wireless communication capabilities. This allows in-situ mapping and logging of field observations for a variety of applications.
