  1. Team Arundo del Norte Weed Data Collection, Aggregation, and Sharing from the Ground Up Deanne DiPietro Sonoma Ecology Center

  2. State-Level Aggregation Site Field Desktop Multi-Partner DB A story of data management and aggregation

  3. Team Arundo del Norte Project Needs • Assist 9 orgs with mapping and data management • Monitor treatments eradication, and change in vegetation • Aggregate data, display and analyze together • Share data at state level

  4. The Search for a Data Management System Trade-Offs of Low-Tech vs High-Tech • Costs of equipment • Learning curveOR • Data standardization and quality control Lots of experience with the heartbreak of bad data

  5. TNC’s WIMS… • MS Access desktop with handheld & ArcPad • Good field data model: Occurrences, Assessments, Treatments • Field tested and many things figured out

  6. Modifications to WIMS • Data safe-guarding • Additional and extended data elements • Tighten up semantics and usage ambiguities • User interface • Data quality management

  7. Announcing Supports quality data capture, error detection, and aggregation http://geoweed.org

  8. Step 1: Enter Admin Data and Field Data Forms Step 2: GIS Export and Background layers GeoWeed Desktop Database Step 4: GIS Import GeoWeed Work Flow Step 3: Field Data Collection

  9. GeoWeed Schema • Referential integrity rules enforce important dependencies Assessment Occurrence Assessment Assessment

  10. GeoWeed Schema • Referential integrity rules enforce important dependencies • Prevents data from becoming corrupted Assessment ? Assessment Assessment

  11. New Data Elements • Survey (vegetation monitoring and absence data) • Work Session and Project metadata • Contacts • Photo Monitoring and photo file management • Revegetation log

  12. Clarification of “OAT” data elements Occurrence • Occurrences, Assessments, & Treatments tied together like a string of beads Assessment Treated Assessment Time Assessment Assessment

  13. Occurrences Surveys Sessions Patch 2A Patch 2B Patch 3A Patch 1B Patch 1A March 13, 2007 Oct. 10, 2007 June 3, 2008 Aug. 13, 2008

  14. Powerful and Intuitive Desktop Use Interface • Record summary displays tell you what you’ve got • Jump directly to all your data by type

  15. Desktop User Interface, cont’d • Related records available from every record • Filters (instant queries)let you rapidly explore your data and get summaries

  16. Data Navigation: Stacks Examples: • Assessments for a given Occurrence • Treatments done in a given Work Session • All Surveys in a Region User views/edits a “stack” of related records with each Form, rather than just one record. Can step thru the stack, without returning to a previous form and going forward again.

  17. Form View- scroll through stack Table View- see it all

  18. The GeoWeed Navigation Bar: the same navigation functions on every form Record type Scroll buttons and number of records in stack

  19. Navigation Bar: History Go! History list: Has the name of the stack and the time viewed

  20. History Menu

  21. One click and you’re back to the Top Menu

  22. Data Quality Management • Tools for immediate problem-flagging and fixing Something wrong here! Check, clean, and calculate

  23. Internal documentation: Use of the Treatment Polygon You can use the polygon tool to: • define the area actually treated • “lasso” the infestations being treated GeoWeed tracks which you mean so the treated area can be calculated and reported correctly later

  24. Hoping to find funding to complete: • Web-based drill-down reports and diagnostics • On-board maps • Data import wizard (from WIMS or any source) • Automation of data feeds to aggregation servers (both rich-set and NAWMA)

  25. Aggregation Utility

  26. Drillable Reports with Diagnostics

  27. Data Aggregation and Online Map Displays TAdN Map Server BIOS CRISIS Maps

  28. Multi-Partner Database Aggregation Utility (GeoWeed Plus)

  29. Static Maps Posted Online http://teamarundo.org

  30. New TAdN Partners Map Server

  31. Use Cases and Issues Use Cases- • Present the collective work and progress of the 9-partner project • Allow for a visual overview of the whole project • Analyze efficacy, statistics across partners Issues- • How much to show the public?

  32. State Level Aggregation and Data Sharing • Exhaustive search for No. Cal. Arundo data • Data compiled from 24 organizations • Consolidated into one simplified NAWMA-compliant layer • Metadata created for each original dataset and for consol. layer

  33. DFG BIOS Use Cases- • Share data at state level • Provide display with other enviro. data Agreement with Cal-IPC to host invasive plant data

  34. Arundo and Chinook Critical Habitat

  35. Data Model- NAWMA Some NAWMA Fields had to be generated Gross Area and Infested Area were calculated if polygons or area measurement available, left blank if point only Metadata for source dataset linked in every record

  36. Metadata:CEIC • Facilitates discovery and sharing of data by download or contacting owner • Official state environmental data catalog • Run by CERES

  37. CEIC • The Team Arundo del Norte Catalog on CEIC http://gis.ca.gov/catalog

  38. NBII CRISIS Maps • National level data sharing • Multiple aggregators • WFS (Open GIS) services

  39. State Level Aggregation Use Cases • Evaluation of weed distribution • Support requests for funding • Index to available data sources • Early detection and alert system • Analysis and modeling (?)

  40. Issues • Absence of data vs. Absence of weeds • Tracking treatments • Incremental updates of assessments and treatments • Different semantics in source data • Moving data quickly- automated data feeds

  41. Needs • A working content and format standard • Determine your use cases! One size does not fit all • Regional aggregators • Training • Field data collection protocols • Metadata at every level of data management

  42. Sonoma Ecology Center Services • GeoWeed training and support • Software development • Help with data management and aggregation • Working with ICE and NBII on data networking issues….”WeedNet”
