The California Ocean Uses Atlas Project fills a critical information gap in ocean management by providing an unprecedented, comprehensive, consistent and spatially explicit picture of human uses for management agencies, policy makers and stakeholders interested in sound and equitable ocean governance. Using participatory GIS concepts and applications, the Atlas Project generated spatial data and map products illustrating patterns, intensity, and temporal changes in a wide range of human uses in three broad categories of use: (i) fishing, (ii) non-consumptive, and (iii) industrial activities. The resulting datasets depict patterns of ocean use on a broad scale appropriate for a variety of ocean planning and management needs. This dataset contains the fishing activities, and is part of the larger California Ocean Uses Atlas database.

Data sources used in this process:
Attribute accuracy was maintained by comparing data before and after each process step, and by comparing final product to source data.
Workshops were conducted at a maximum scale of 1:250,000. During post processing, original workshop polygons were aggregated to an ordered one nautical mile grid, so exact use locations within each block are not discernible. Data are intended to portray broad patterns for each use at a comparable scale to inform ocean management but are not intended for navigation or enforcement purposes.
Recreational shore-based harvest and Hunting for marine animals other than fish or invertebrates were added after the first workshop (Southern California) so there is no data for that region. Commercial fishing with benthic mobile gear was not mapped in Central California due to insufficient knowledge of this use among workshop participants. Recreational fishing from boats was mapped as a single use in Southern California but was mapped separately for benthic and pelagic activity in the other 3 regions. In order to provide a consistent statewide dataset, the recreational boat fishing data for those 3 regions was combined to represent both benthic and pelagic fishing. In 3 of the 4 regional atlas workshops, an attempt was made to map uses of the ocean by tribal peoples. Two distinct approaches were taken. First, we mapped tribal activities taking place within the existing range of ocean uses addressed by the Atlas project (e.g. tribal pursuit of benthic fishing with fixed gear; beach use by tribal peoples). Most of the resulting tribal use patterns fell within either the general maximum footprint or the dominant use area drawn for those uses by other non-tribal participants and are thus not represented as uniquely tribal activities.Second, we attempted to map distinctly tribal use areas tied to specific geographic locations of special cultural, spiritual or historical significance. Although some tribal participants provided relevant information, not all tribal interests were represented in each workshop and some participants were reluctant to portray use patterns of other tribes. As a result, the resulting maps of tribal activity patterns may depict an incomplete or misleading picture of the full spectrum of tribal uses of the ocean in each region. Consequently, in order to avoid misinterpretation of the tribal use patterns, and to maintain data consistency and integrity throughout the Atlas maps, the tribal use data are not explicitly depicted in the public release of the atlas data or map products. They will, however, be provided to the California Marine Life Protection Act Initiative and to the tribal participants for their use, with appropriate explanatory information about their content and limitations. For additional information on the tribal ocean use data, please contact the MPA Center.
Logical consistency was maintained by comparing data before and after each process step, and by comparing final product to source data.
