Data/ Software

• Data: Open? -- mostly• Example: USGS Data holdings

– 8 Layers of the National Map– Soon: Hyperspectral cubes and LiDAR point clouds

• Software: Open? – mostly not in GIS• Source Code: Open/ Modifiable?• Software Package: tight/ coherent system?• Functional?• Example software: mapIMG (based on CGTP)

Open GIS: Technology and Applications• 2 of D. Sui’s “Four Opportunities of Open GIS” • GIS: combining data & software GIS Packages

– Legacy of primarily commercial software

• Early wide-spread but often spotty “open” GIS– e.g. QGIS

• Foundation for maturity, expansion, and further openness

CyberGIS

• CEGIS participation• Cyberinfrastructure (eScience)• HPC & GIScience• A balance/ interaction between theory/ data (S. Rey)• Collaborative Research• Standards (for interoperability)

• Openness• e. g. OGC; XCEDE

Toolkits

• Eliminate/ Remove/ Reduce License confusion• Hide compute complexity • Assist with modeling/ analytics• e.g. CyberGIS Toolkit (pRasterBlaster as a component)• Lessons learned; contribution: parallel I/O for raster;

NetCDF and GeoTIFF

Spatial Modeling/ Analytics (GeoViz)

• Solving “Changing World” Problems• Democratizing Science • Products and Services for society and its citizens
