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
The digital datasets
•
Eight themes
•
Standard map series
•
Available individually
•
Completeness and consistency
•
Set standards
•
Available in different formats
•
Input from multiple sources
•
Integrated data
•
Compatibility with other GIS data
•
Cartographically correct
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)
DHS Urban Areas
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 7.5minute 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?

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
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
