San Diego Imagery Options for 2011 and beyond
The National Map • The National Map is built on partnerships and standards • The National Map is built upon eight data layers: hydrography, elevation, orthoimagery, geographic names, boundaries, transportation, land cover, structures • Public domain data support • topographic maps at 1:24,000-scale • products and services at multiple scales and resolutions • analysis, modeling, and other applications at multiple scales and resolutions
Components The National Map is a collection of digitally produced maps in several formats built on individually produced and maintained layers. It can be expressed as two parts: • TNM products • Standard map series • Completeness and consistency • Available in different formats • Integrated data • Cartographically correct • The digital datasets • Eight themes • Available individually • Set standards • Input from multiple sources • Compatibility with other GIS data
Imagery generation possibilities • National Agriculture Imagery Program • DHS 133 Urban Areas • Standalone local/regional/state projects • Combination of the above
NAIP – National Agriculture Imagery Program • Based on Farm Service Agency (FSA) need to monitor crop programs • Offers nationwide data over three year cycle • Basic product is one meter, color infrared or natural color, leaf-on orthoimage • Statewide NAIP completed for CA in 2009 and in progress for 2010 but not planned for 2011 • Possible half-meter and four band upgrades (even some leaf off flights)
Homeland Security urban areas (aka 133 cities) • One foot, or better, natural color imagery • Optimal refresh cycle is two to three years • Covers 133 major urban areas across USA • Funds provided by National Geospatial-Intelligence Agency (NGA) but applied through USGS • Funds generally sufficient to create a standard one foot product • Each urban area has a defined footprint based on 7.5-minute quadrangles • Partnerships with local and regional government are welcome (examples include CIRGIS, LA County, Imperial County, Solano County, Kern County) • Partnerships can extend projects beyond NGA footprints and improve resolution and image band selection
Homeland Security urban areas (continued) • Public domain data are preferred • Restricted use datasets are possible though with a public access release after a certain time • Requires permission to collect and distribute data over military installations • Projects can be managed by partnering agencies or by USGS Commercial Partnerships Team • USGS manages vendors through Geospatial Products and Services Contracts (GPSC) • GPSC has pool of vendors and subcontractors. Qualifications based selection. • GPSC can develop Independent Government Cost Estimate • Partners are able to request certain vendors if on contract
San Diego Region imagery considerations Meeting held at USGS in September to address • Areal extent – is whole county needed? • Areas with better than one foot resolution? • Custom flight or off-the-shelf? • Any data licensing or restrictions? • Contracting mechanism? • Possible interested groups • Data refresh cycle?
San Diego Regional Imagery Planning meeting Attendees • SDSU Homeland Security • Caltrans • San Diego County • SANDAG • USMC • US Navy • USGS
General conclusions • Look at whole county coverage • Minimum of one foot resolution with possibility of 6 inches for urban areas – blend simplicity with max utility • Get prices for basic urban area and then whole county • Determine who are possible contributors • Define rough costs for different groups • Agree on contracting mechanism
Cost estimates • Await numbers from USGS Commercial Partnership Team • Best equivalent project is Imperial County collected by RFP vendor 2008 (4,000 square miles, $270,000 (or $70/mi2)) • Cost likely to vary further if combined with other projects in Riverside, San Bernardino, and Imperial Counties
To do • Receive estimated costs and verify final NGA contribution amount • Share costing information with SDRGC • Share info with other outside groups (state, fed) • Develop funding scenarios • Hold 2nd planning meeting
Regional Lidar • High resolution elevation data exist for cities of San Diego, Poway, and Chula Vista and along border • Lidar also collected by NGA for San Diego for ~105 square miles – data acceptance and distribution method in work • Need for regional lidar • What do we need? Point density, DEM/DSM grids, bldg footprints, point clouds, etc. • USGS estimate from 2009 is $1,000,000+ for whole county • USGS has lidar Guidelines and Base Spec
