Topographic Maps from The National Map

U.S. Department of the InteriorU.S. Geological Survey

NGAC Meeting

February 4, 2009

The National Map

Seamless, continuously maintained, nationally consistent base topographic data

Developed and maintained through partnerships

Available on-line Source for products and

services

Overall Strategy

Create next-generation USGS topographic maps 3 year revision cycle following NAIP Source data from The National Map databases

National Transportation Dataset (from Census initially) Names (GNIS, NHD) Cartographic features (Grids, quad level metadata)

Initial product will be basic e-Topo Image Map content Image background Roads Names 1:24,000-scale layout

Map Product evolution Data layers will be added as they become available and

technical processes are in place Elevation data (contours) and Hydrography highest priority

Product Characteristics(It’s not your grandfather’s topographic map)

The product is a plottable digital image. It is neither a GIS dataset nor a traditional paper map, but a new kind of hybrid.

The physical format is GeoPDF, an unpublished and proprietary format that can only be read by specific proprietary software.

The PDF is layered and georeferenced, giving the dataset some limited GIS characteristics.

FY09 Goals and Preparation Produce 15,250 e-Topo Image Maps and make

them available through the USGS Map Store Initial product will be basic e-Topo Image Map

content Image background Roads Names 24K layout

Processes will be managed with Job Tracking Extension (JTX) Multiple parent and child jobs Can be extended to future product(s)

Begin production of AOI phase 1 cartographic data Grids (UTM, state plane, geographic)

Near-Term Issues

Short-term ramp-up to get to 15,250 maps/year Standard is still in review/approval process

E-Topo and Image map standard becoming one standard

Data availability to NGTOC locations 1-meter NAIP imagery, leaf on

FY2008 NAIP is not available yet so use FY2007 DOI & USGS now a funding partner to NAIP NAIP is in quarter-quad format

Workflow development

Longer-Term Issues

Data completeness, quality, currency In many cases, there are no national, public domain data

sources available for 1:24,000-scale mapping Boundaries PLSS Structures Transportation (roads, other trans features)

Data integration between themes

Longer-Term Issues

Examples of data integration issues

Temporal Difference?

Approach to resolving data integration issues

Inventory and document the types and prevalence of issues

Focus on adding layers to product as data are ready for inclusion

Develop approach and process for integrating hydrography and elevation in FY09

Begin to add these data to the map products in FY10

Summary

The next generation USGS topographic map product will evolve and improve, in terms of content and quality

Near-term challenges include defining the product and putting processes in place to produce in quantity; automation is critical to making this work within existing resources

Longer-term challenges are data-oriented, including consistency, currency, completeness, especially in themes that are not USGS’ A-16 responsibility
