Inside eCoastal

eCoastal is a GIS data repository for the US Army Corps of Engineers San Francisco District (SPN). eCoastal utilizes spatial data standards, enterprising geodatabase development and desktop and web applications.

With eCoastal online, you can access GIS data via web mapping services as well as download bathymetric XYZ hydrosurvey data.

Both the eCoastal Geoportal and USACE Geospatial Platform allow users to view a gallery of premade maps.  They also provide access to web mapping services that can be used for creating your own maps without using GIS desktop software.

The public Geospatial Platform viewer provides geospatial data, services and applications for use by our partner agencies and the public.  Search for "SPN" to see maps and data layers specific to the San Francisco district.

eCoastal is a repository for all types of coastal and navigation geographical information including bathymetric surveys, navigation channels, dredging histories, coastal structures and project footprints in the vicinity of the San Francisco district civil works boundary.  Data produced by the San Francisco district engineering and technical services division is based on Spatial Data Standards for Facilities, Infrastructure and Environment (SDSFIE).
