Presentation Transcript

  1. Center for Geographic AnalysisHarvard University • CGA is a member organization of the Institute for Quantitative Social Science (IQSS • CGA has 3 full time staff and several part time members CGA’s website: • CGA services are available to all schools, departments and other organizations across Harvard.

  2. CGA Goals • CGA focuses on research and education in the field of spatial analysis and geographic information. • The Center’s goal is to work with entities across the university to • strengthen university-wide GIS infrastructure and services; • provide a common platform for the integration of spatial data from diverse sources and knowledge from multiple disciplines; • enable scholarly research that would use, improve or study geospatial analysis techniques; and • improve the ability to teach GIS and spatial analysis at all levels across the university.

  3. CGA Basic Services • Maintaining help desks in both campuses; • Consulting with students, faculty, and staff on research and teachingprojects; • Consulting on grant proposals; • Providing non-credit group instruction in geospatial software applications on a regular basis; • Assessing, organizing, financing for, and maintaining university site licenses for software; • Providing hardware and support for geospatial tools; • Undertaking initiatives that improve the university infrastructure in relation to geographic analysis.

  4. Research Consultation • Data issues, e.g. • Public and commercial data sources • Data collection and management techniques • Data conversion, scanning, digitizing, etc. • Hardware/software issues, e.g. • What GPS to buy – accuracy, compatibility, etc. • Which software to use for various tasks • Methodology issues, e.g. • How to select parameters in spatial interpolation • How to build location-allocation models • Visualization issues, e.g. • How to do 3-D maps or time-series animation • How to allow users make interactive maps from a web browser

  5. Project Partnership • Jointly write grant proposal • Manage contracts, outsource data development or programming tasks • Perform analysis for a project • Automate analysis procedures • Write technical documents, users manuals, training materials, etc. • Conduct customized training for long term project assistants

  6. Instructional Service • Semester courses in Faculty of Arts and Sciences • Winter recess courses in Harvard Medical School and Harvard School of Public Health • Non-credit GIS training seminars • Customized GIS course modules in various courses (e.g. history, business, government) • Extension school courses in GIS • Online tutorials and self-learning materials

  7. CGA Software Administration Site licensed software • ESRI – complete suite of products (ArcGIS) and extensions • Leica Geosystems - ERDAS Imagine • Safe Software – FME • Clark Labs - IDRISI Andes, Land Change Modeller • Google Earth Pro (260) • Arc2Earth Pro (1) • Global Mapper (1) • ESRI Business Analyst 2006 (1) • Trimble Pathfinder Office (1), Trimble GPS Correct (2) • Garmin MapSource (2) • Visual Learning Systems - Feature Analyst for ERDAS Imagine (1) • Adobe Illustrator, Photoshop, Dreamweaver, VPN Client. Other software (number of licenses) Other relevant software available free for Harvard use at

  8. Infrastructure Maintenance • Computer labs on both campuses • GPS and field data collection equipments in loan • CGA Website • Monthly Newsletters

  9. Academic Events • Workshops (symposium, mini-conference) • CGA Launch / GIS symposium (May 2006) • Remote Sensing Workshop (Feb. 2007) • Georeferencing Workshop (March 2008) • Executive Session on Situational Awareness: Assuring Cross-Boundary Information Sharing in a Geospatial Environment (May 2008) • Academic Seminar Series and Colloquia • Technical Seminars (monthly) • Student Awards • Howard T. Fisher Prize in GIS for undergraduate and graduate students
