USGIN WMS profile for integrated geologic map Web Map Services

The key to interoperable map services is the ability to portray adjacent maps using the same symbolization scheme such that when the maps are displayed, the visual discontinuity at the boundary is minimized. Because of the discrepancies in mapping interpretation and intention, there are commonly discontinuities in the definition of map units between geologic maps produced by different authors or at different times. These discontinuities cannot be avoided, and resolving them is a compilation process that will often require additional field work; this is outside the scope of service deployment. What can be avoided is visual discontinuity related to portrayals based on different classification schemes on adjacent maps. Map unit classification schemes for regional geologic maps typically define units based on some combination of age, genesis, and lithology. The larger the area over which the scheme is meant to apply, the more generalized the definition of the units must be.

USGIN Catalog and Data Services website released

The USGIN Catalog and Data Services website ( hosts several geospatial metadata catalog (CSW) and geospatial data services (WMS, WFS, WCS) implementations and clients. Although the site functions as a showcase of USGIN service implementations, the Catalog Service for the Web service (CSW - is a primary metadata node for the U.S. Geospatial Information Network.

Available services and clients at this time:
