## Slide 5

## Species Locality Data

**Species Locality Data**
- Plot data collected by
- various groups for different
- projects- compiled for modeling
- effort.

- Conversion of plot species data to input data for modeling

- Selection of study area exent

- Sample Range Model: Current and future ranges
-                both shown in one image.

**CalJep Map Units**
**283 units for California**

## The Semantic Web:Tools for Creating a Standard Data Reporting Structure 

- XML: Extensible Markup Language
- Emerging as a standard way to exchange structured data – Expresses semantics (vocabularies, etc.) of a network
- RDF: Resource Description Framework
- Good for expressing the ontologies (relations between data resources) ina network
- Other Open-Source technologies
- Web Ontology Language (OWL)
- Open GIS (OGIS) and Geographic Mark-up Language  (GML)
- Ecological and sensor markup languages?

## CRISISMaps – An Open Source Invasive Species Mapping System

## Yellow Starthistle by Township in California

## Project Catalogs

- California efforts mostly project catalogs:
- Natural Resource Project Inventory (NRPI)
- Initiated by California Biodiversity Council
- Projects, Restoration Projects, CalWeed
- CALFED/SFEI
- Prop. 50 projects
- FGDC Clearinghouse / NBII catalog / NRIS
- Federally funded projects
- EML Clearinghouses (LTER, NCEAS)
- NSF-style research projects
*others*
- Redundant and high-maintenance
- Limited information content – best for information discovery

## Slide 20

## Arundo donax

*Arundo donax*

- Has invaded thousands of acres in Southern California
- Destroys riparian habitat
- Flood and fire hazard

## The Study Site:Camp Pendleton Marine Corps Base

## AVIRIS Data

- Low-altitude AVIRIS
- 3.9 m pixels
- Collected Sept., 2000
- Calibrated to reflectance with ACORN (Atmospheric Correction Now)

## Ground Spectral Data

- Spectral data collected for several species and a large parking lot
- Locations recorded with GPS
- Used as input into atmospheric calibration and to evaluate its success, and for ROIs

## Maximum Likelihood Classification

- Very good results obtained with .98 threshold
- Visual inspection shows that most areas are classifying correctly

## Techniques Compared

- Continuum removal
- Unsupervised classifications
- MNF/Supervised classifications
- MNF/Spectral Angle Mapper
- Methods explored for guiding endmember selection

## RipTopo Riparian Corridor

## RipTopo & Aquatic Conservation

## Citizen monitoring

- Critical for applications such as detecting new invasive species
- Data quality concerns
- Treat with metadata, not filters
- Attributes?
- Annotation
- Digital field forms – Standardized output
- Example – NAWMA*
- Digital field identification tools

- *North American Weed Management Association

## Slide 30

## Citizen monitoring

- Information / IT Needs:
- Better help materials
- Standard vocabularies
- Methods to automatically upload data
- Or better yet, post locally and crawl
- Semantic Web technologies
- Methods to push data to recipients
- RSS feeds?
- Spatial modeling and map-based visualization
