Digital Library Presenter: Gary Phelps Prof. Guo Lab School of Engineering

Outline Background of Digital Library Development –Zope overview –Metadata and Spatial Data –Demo

Background Easy way to store & share data Search, Upload, Download, etc. Secure way to share data –Public vs. Private data sharing –Assignable permissions (access control) –Metadata Functionality and Spatial Extent Assign metadata for each data uploaded Assign spatial extent for each data uploaded

Development Point Data –Longitude/Latitude marker display Spatial Extent –Polygon of existing data –LiDAR functionality Multi-tabbed for overlying extent –DEM, DSM over same extent Both viewable in map –UTM convertible if necessary

Metadata and Spatial View Metadata File z File y File x Spatial View Metadata -Multi File control Spatial Extent -Ex: LiDAR flights, transects, etc. -Point data (collected at particular location). -Uses Google Maps API -KML functionality

Spatial Data Can store an up to ~3gb per file –LiDAR is typically very large –Other large datasets Can create FTP site –Large transfers and downloads –Can also download metadata with data

Development Built with open source library Zope Zope –Content management –Python extensible (easy development) –Security assignable –Relational Database (catalog) –Supports many different languages Python, Html, JavaScript, etc.

Check boundary for metadata match of file(s) Create Zip File of metadata and file(s) Return files(s) that fall within search
