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

SurveysSessions

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)

Aggregation Utility

Drillable Reports with Diagnostics

Data Aggregation and Online Map Displays

TAdN Map ServerBIOSCRISIS Maps

Multi-Partner Database

Aggregation Utility (GeoWeed Plus)

New TAdN Partners Map Server

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

http://gis.ca.gov/catalog

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
