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

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

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

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

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

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

Announcing Supports quality data capture, error detection, and aggregation

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

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

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

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.

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

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

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

History Menu

One click and you’re back to the Top Menu

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

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

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)

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?

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

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

Arundo and Chinook Critical Habitat

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

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

CEIC The Team Arundo del Norte Catalog on CEIC

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

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 (?)

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

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
