  1. Collaborative Maps: Some Initial Research Familiarization & Brainstorming June 8, 2004

  2. Some questions: • The CORK encapsulation structure seems to allow easy adaptation of single-user programs – can we do this simply by just storing an app’s methods into a database and wrapping everything with CORK objects? • How is this tool different from the paint tool with layers? Is it just a more advanced paint tool? • Is it vector/raster compatible? Latitude/longitude? • Should we study GIS tool design? (eg. GeoVISTA?) • Objects: Database or XML or GIS objects? • Navigation issue: is a better key-id file structure possible? • Please explain Bridge and the various CORK layers as applied to this map editing tool June 8, 2004

  3. Goal: Find Comparable Tools? • What categories of single-user tools? • GIS (including GIS database pools) • Raster/vector modeling • CAD • 3-D Modeling • What categories of collaborative tools? • Joint Editing Systems (CMS-related) • Extensions of CAD or GIS software • Multi-user online 3D environments (games) • Search engines for other uses, databases • WYSIWIS for instructor v. student permissions June 8, 2004

  4. Examples of what’s out there: • Toucan Navigate • http://www.infopatterns.net/Products/ToucanNavigate/TNDataSheet.pdf • commercial Groove software, best relevant tool found • Comprehensive interface • Features: • Co-navigation options • Sharing map databases • Customize layer options • Map item details • Zoom • Address look-up • Editing window June 8, 2004

  5. More examples of what’s out there: • CAD Synchronous Collaboration tools: • AutoVUE, CoCreate’s OneSPACE, ArcView, etc. • Synchronous CMAP Tools http://cmap.ihmc.us/mapindex.html • GeoVISTA Studio http://www.geovistastudio.psu.edu/jsp/index.jsp • Geocollaboration: multi-modal GIS CSCW June 8, 2004

  6. Task Analysis Projects Already Done: • Book: ‘IT Roadmap to a Geospatial Future’ • Report by National Center for Geographic Info & Analysis: http://www.ncgia.ucsb.edu/Publications/Tech_Reports/95/95-14.pdf • Outlines usability issues • Contact them and see what info they have on current research? • How does current theory on “collaborative spatial decision-making” and “multi-criteria decision-making” apply to making a toolkit? • They discuss the collaborative solution-seeking PROCESS • Stages that might apply to map interface uses, processes: • 1) Strategizing: getting background info, approach • 2) Exploration: generate solutions • 3) Convergence: narrowing focus, evaluating, interpolation June 8, 2004

  7. Clarification of goals • What is the immediate goal? • What is the audience and environment and how diverse are their skill levels? • What were the limitations and advantages of the previous tools? • What would be best to imitate? • Can we streamline the whole process of adapting single-user apps to Bridge? • What are the datasets like? June 8, 2004

  8. Scenarios, Possible Tools • Slightly harder: Radar lines Ruler and spatial measurements Background grid Linking to other maps Key features or region database Navigator options: baton passing vs. synchronous • Simple: • Movable objects, fronts • Textboxes • Cut & Paste • Zooming in • Changing angles • Selecting shapes • Snap to map lines • Harder: • Contours & related GIS data • Pixelated building view • (eg. Habbo, SimCity) • Change over time, Interpolation • Synchronizing differing displays • (eg. Ground level vs. top level) • Building custom views and simulations • How about an option to add more tools if necessary but to keep the interface simple otherwise? (scaffolding) June 8, 2004

  9. Engineering design Scientific modeling Building design Library interfaces Land surveys Meterology Transportation Graphic design Exploratory collaborating Collaborative database mining Potential Applications • Business Forecasting • Medical collaboration • Scientific modeling • Building design • Library interfaces • Shared virtual spaces • Historical tracing • Co-editing • Website/graphic design • Better concept mapping June 8, 2004

  10. How Do We Get There? • Any relevant background information • Design Framework: CORK, Bridge • Timeline • Design document? June 8, 2004

  11. Available Options • Get GeoVISTA code, adapt to Bridge? • Make simpler tools from scratch first to discover implementation issues on a smaller scale? • Get a licensed copy of Toucan Navigate from infopatterns? June 8, 2004

  12. Notes from the Meeting: • Cork: • Single-user apps can be adapted only if: • Code is in JavaBeans with clear-cut set/get mechanisms • Latitude/Longitude/Elevation • GIS v. Shapefiles v. SVG? • What kinds of metadata come with these types? • Elevation data? Vectors? • Explore open-source solutions like GeoTools, OpenMap, contact GeoVISTA June 8, 2004

  13. Notes from the meeting (cont’d): • Not just for the GIS community: • Community groups, Historical society, Teachers • Bridge file structure • better user readability • permissions verification and easier deletion • (Maybe an id-based database would also be useful depending different types of kind of map data for networking nodes) June 8, 2004

  14. Notes from the meeting (cont’d): • Coding: • What will be the necessary shared objects? • There are things we don’t need to share like map shapefiles that are too big • Current work: • Developing a web version of the map for the historical society • Zoom features on the web version • Panning • Snapshots/Thumbnails June 8, 2004

  15. Next Steps: • Meet with GeoVista Studio developers (see Lu’s agenda email) • Get some standard map files – which format is best? • What tools are absolutely useful? • Get their sourcecode. Is their code CORK-worthy? • Ask them about comparable tools • Contact Toucan Navigate about a demo and possible collaboration • Meeting on using CORK on Monday: • What are the multiple layer replication features and how to identify good single-user apps to possibly adapt?
