Invasive Species Systems Task Group Status Update and Some Performance Analysis: 

Invasive Species Systems Task Group Status Update and Some Performance Analysis Jim Graham PhD Candidate, Colorado State University Annie Simpson, Michael Brown, Greg Newman, Catherine Jarnevich, Tom Stohlgren

Invasive Species: 

Invasive Species $120 Billion spent annually in the US Between 5000 and 50,000 invasive species in the US Impact agriculture, environment, and human health Reduce area for viable grazing 46% of species on threatened and endangered list are listed because of invasive species Human health concerns (e.g. West Nile Virus)

Resource Managers Need Help!: 

Resource Managers Need Help!

Invasive Species System: 

Invasive Species System Herbariums Museums Invasive Databases Inspection Databases Portals Search Engines Modelers Users Consumers (Clients) End-Users Providers (Server) Web Services Web Pages

Customers: 

Customers End-Users Researchers Citizen scientists Decision makers Resource managers Data Consumers Modelers Map Generators Portals Data Providers Over 252 invasive species databases in the US alone (Crall et al. 2006)

Research and Production: 

Research and Production

Software Lifecycle: 

Software Lifecycle Investigation Design Implementation Testing Maintenance Time

ISSTG Initial Schedule: 

ISSTG Initial Schedule October, 2006 – Formation of TDWG task group December, 2006 Investigation completed – Draft design February, 2007 – Design completed May, 2007 – Test implementation September, 2007 – Toolkits available?

Current Status: 

Current Status Investigation Initial use case analysis Draft requirement specification Starting alternatives analysis Starting feasibility studies Design Draft schema Terminology definition tools Implementation Prototypes

Use Case Analysis: 

Use Case Analysis Example Cases Create map of species Research status of species Find environmental niche of species Research control methods Find native distribution of species Possible Actions Refer to existing solution Build web site Build portal Add to the protocol

Some Requirements: 

Some Requirements Provider Requirements Common language support Platform independent Broad database support Easy to implement, use Fast access to large amounts of occurrence data

Invasive Species Data: 

Invasive Species Data Existing Standards Locations Taxa identification Dates Depth, Elevation, Sex, LifeStage Extensions BioStatus (non-native, harmful) Additional ancillary data (percent cover, date introduced) Management information Life history

Additional data:

Search Times on Resources: 

Search Times on Resources Times are in seconds

Performance Variables: 

Performance Variables Internet connect speed Number of hops between client and server Server speed Web server software Protocol complexity (3) Provider software (3) Database software Database structure Number of records (1) Search type Fields requested Number of matches (2)

Search time vs. number of records:

Protocol and Provider Software: 

Protocol and Provider Software

Typical Harvest Times?: 

Typical Harvest Times? - Times are in seconds unless noted otherwise - Only the Internet sample time includes Internet latency

Conclusions: 

Conclusions Protocol fit to draft requirements Removing embedded requests improves performance and robustness Current DiGIR SW has performance problems with SQL Server Will look at: other provider software Simple request/response Schema fit to requirements Portions of DarwinCore and ABCD Additional extensions

Duplicate Standard Nightmare!: 

Duplicate Standard Nightmare! TIFF Too complicated to use Toolkits were late JPEG, GIF, IMG, PNG, EPS, Targa… Thousands of formats! TWAIN Simplest solution that met the requirements Delivered with cross-platform toolkits Only scanner interface standard Can we get all the folks working on occurrence data together?
