Planetary Data in Learning Environments
A Community Workshop
Monday, August 1, 2005
What technical issues are involved in data access and use for developers and end-users?
Each group should designate a facilitator and a scribe.
The scribe will document the group discussion (computer, notepad); notes will be given to the program organizers.
The facilitator will report out to the workshop participants at the close of the group discussion. Please refer to the “Group Report-Out Questions”
Possible guiding questions:
- Are the appropriate data available?
- Are they easily accessed and utilized by the developer; if not, what practical steps are needed to make them easily accessible?
- Are they easily accessed and utilized by the end-user? Steps needed?
- What exemplary programs exist?
- What research exists / is needed with respect to this topic?
- What is needed to ensure collaboration between the provider, developer, and end-user?
Group Report-Out Questions (facilitator)
- What were the major findings / discussion points?
- What needs were identified? / What additional information is needed from this community group?
- What are the priorities?
- How can the PDE Initiative assist? How will this community group interact with the PDE?
- What are the next steps to address the needs and priorities?
Group B Discussions – Technical Issues
1. Mix of developers, and uses, comp. sci
- lots of data
- is it free? Change over time (Landsat – available from secondary provider U.Md.)
- high-res info on Earth not available?
2. No
- map projection
- data format
- size of files
- need special tools
- to process imagery (make processed data available (i.e. program)
- tools to quantify data (ImageJ - free, etc.)
- 3-D mappings – go below or above surface
- raw data — ability to use data in real-time; proprietary 3-D ??? tools
- topography/texture mapping
3. Where to get the information? Correct resolution?
- Facilitate dialog between software developer and data providers – create a center or virtual group
- Knowing who is working on it currently — interface — what are real needs understanding how the data are collected
- Allow different levels of processing per the needs of the user.
- Annual conference for software developers for Space Science applications ADAS(?)
- Toolkit for each data format
- Even for science users
- Should have info up front to describe data
- Use consistent formats (formats are complicated – not easy to use)
- Put metadata in one place
- I.e. NVO for Space Science
- Single interface to data wherever they are held
- Caution — Earth Science did not work
- Ideas – digital library may be a good model
- Collect what data are available — different users want different things
Switchboard that allows you to access the data
1. Gateway -> Switchboard info about format
1a. Liason -> Scientists – Computer science - Education (format acceptable to general public
2. Multiple users
- different levels of data use (visualizations, analysis(use numbers and do science))
- Need to allow inquiry-based without continual learning curves for new images or tools; run on multiple platforms
3. Analyse programs out there – exemplary programs (ImageJ, HubbleSource, My NASA Data, Astronaut photos of Earth) EarthSLOT – Matt Nolan U.Alaska - Fairbanks; 3D GIS and terrain visualization tool to look at data all different kinds of data hyperlinked to a specific location: EarthSlot can look at change over time.
