Center (RSAC)

LANCE User Working Group MeetingNovember 16-17, 2010

Remote Sensing Applications Center (RSAC)

• National Technical Center; Located in Salt Lake City, Utah

• Mission: Assist all levels of the agency, and external agency partners, in applying the most advanced geospatial technologies for improved monitoring and mapping of natural resources

• Operational MODIS direct readout data collection since 2002

RSAC X-band antenna in radome

Area of interest

SSECRSAC

UAF

NASA DRL

MODIS Ground Station Network• L0/L2 data continuously acquired and compiled at RSAC

for further processing

• NASA operational MODIS data distribution systems provide additional coverage and backup ground station network

− MODIS Rapid Response System (LANCE)− LAADS

International Polar Orbiter Processing Package (IPOPP) used for L0 -> L2 processing

Active Fire Mapping (AFM) Program(http://activefiremaps.fs.fed.us)

Operational, NRT detection and monitoring of wildland fire activity in CONUS, Alaska, Hawaii & Canada

• Leverages NASA and NOAA assets

− MODIS− AVHRR

• Facilitates decision support for strategic wildfire planning and response for U.S. and Canadian fire agencies

− Prioritize allocation of fire suppression assets

− Focus tactical airborne reconnaissance assets

− Integrated into several fire-related applications and decision support systems

− GOES− Future polar/geo

sensors

AFM Value-Added Fire ProductsMapping/Visualization Products• JPG/PDF fire detection maps• Interactive fire detection map

viewers• Google Earth fire detection

KMLs/KMZs • Detection analysis/summary

products

Imagery/Geospatial Data Products• Georeferenced image subsets• Fire detection GIS datasets• WMS/WFS services

• Update frequency: Every 15 to 60 minutes or immediately after every satellite observation

• Ongoing coordination with fire management community to develop products to meet operational needs

Example Fire Management ApplicationData Input for Spatial Fire Behavior Systems/Models - WFDSS

FS-Pro (Fire Spread Probability) Model

• Probability of fire spread from a known location in the absence of suppression

• Used for long-term projections of ongoing fires

• Used in conjunction with data about values at risk

MODIS data provides fire locations for initial model runs when other sources of intelligence are lacking.

FS-Pro results help managers determine an “Appropriate Management Response” to fires from a strategic and tactical stand point and prescribe adequate resources for fire containment.

MODIS fire detections

• NRT L2 MODIS land, atmosphere and ocean products produced by IPOPP

• Downloadable L2 swath datasets and value-added products

−GeoTiff format

−Quicklook maps

−Google Earth KMZs

• Distribution node for L0 data collected via RSAC antenna

• Supports national/regional scale resource management and monitoring

Forest Service Direct Readout Data Portal(http://directreadout.fs.fed.us)

Example Monitoring ApplicationForest Disturbance Detection and Monitoring

Annual aerial detection survey (ADS) flights conducted by Forest Service Forest Health Monitoring Program

− Specifically map areas of insect, disease or weather-related damage

Prototype MODIS-based change detection program by RSAC identifies forest disturbances/anomalies

Provides information to prioritize ADS flights

− Provide guidance on where to go vs. where not to fly (omission and commission error important)

− 7-10 day response time

Forest Disturbance Detection ProductsReflectance composites for change detection analysis

Nationwide geospatial disturbance products every 8 days

Michigan forest tent caterpillar outbreak 2010

Current year 16-day composite using NRT data

Baseline multi-year composite for same 16-day period; “normal

conditions”

• Provide information on alternatives for acquiring NRT EOS data to support users with minimal latency requirements

• L2 science products < 30-60 minutes post-acquisition are feasible via direct readout (DR) community

−Numerous EOS DR ground stations with data distribution portals

−Regional DR data sharing networks in place to support NRT application objectives and increase efficiencies

−DR data processing technologies are freely available that provide self-contained, scalable frameworks with access to latest SPAs• Increasingly being utilized by DR ground stations

• Available to any user to generate higher level products from L0 data

Suggested LANCE Enhancements Data Latency Considerations

• Additional output formats (GeoTiffs, etc.)

• File compression for faster download

• Additional methods of accessing L2 swath data by FTP download

−Index directories by grid referencing system common to the user community (i.e. tiles, etc.)

• OGC-compliant data/mapping services − WMS for mapping/visualization− WCS for data extraction and analysis

• Integration of custom products for targeted applications

• Coordination with other space agencies to facilitate similar NRT data delivery framework for future sensors

− GCOM-C SGLI (JAXA)− Sentinel 3 SLSTR (ESA)− GOES ABI (NOAA)

Suggested LANCE EnhancementsGeneral Considerations
