Summary

Dataset was created to illustrate the vision for a restored landscape linkage in Coyote Valley. This data was used for Figure 7 in the report. Report citiation is Santa Clara Valley Open Space Authority and Conservation Biology Institute. 2017. Coyote Valley Landscape Linkage: A Vision for a Resilient, Mulit-benefit Landscape. Santa Clara Valley Open Space Authority, San Jose, CA. 74p.

Description

This data represents the vision outlined in the Coyote Valley Landscape Linkage: A Vision for a Resilient, Mulit-benefit Landscape. The Report was completed in 2017 and was developed with input from a scientific advisory team facilitated by the Conservation Biology Institute.

The dataset and vision is based on and adapted from historical ecology data (Grossinger, RM, RA Askevold, CJ Striplen, E Brewster, S Pearce, KN Larned, LJ McKee, and JN Collins, 2006 . Coyote Creek Watershed Historical Ecology Study: Historical Condition, Landscape Change, and Restoration Potential in the Eastern Santa Clara Valley, California . Prepared for the Santa Clara Valley Water District.

HideScope of quality information


Data quality report - Formal consistency
Evaluation method
Vector data was created from a compilation of historical narrative sources (surveyor notes, explorers' journals, travelers' accounts, and newspaper articles), and from information derived from georeferenced historical maps and georectified historical aerial photographs. Features of interest were often developed using multiple georeferenced sources, and digitized using a heads-up method on screen. Features were digitized at a scale of 1:5000 or less. The final placement of features was checked against other georeferenced sources and adjusted if needed. Whenever possible, historical (USDA 1940/42) and contemporary aerial photography (NAIP 2005) were used as a basis of comparison.

Data quality report - Completeness omission
Measure description
To build the GIS, we collected information about historical conditions from a wide array of sources. These included materials produced by both federal and local agencies, individuals, Spanish/Mexican-era residents, professional and nonprofessional cartographers, and photographers, writers, engineers. Since these data were originally produced for different reasons using a range of techniques, we developed substantial background scholarship to guide accurate interpretation. To develop as strong a historical data set as possible, we acquired materials from a wide variety of institutions. Despite the integration of multiple sources, it should be recognized that this geodatabase is not necessarily a complete or uniform picture. Undiscovered historical resources still exist, and could potentially reveal new and relevant information. For this reason we carefully documented the sources used in mapping as part of the GIS. We also note some potentially valuable sources of information that we were not fully able to assess in the course of this project.

Data quality report - Quantitative attribute accuracy
Measure description
Each feature class has attributes that record the variations in the data, including habitat type, primary and secondary source, and certainty levels. Each is described more fully below. Additional information, including the full bibliographic references to citations used in the source attributes, can be found in the forthcoming Napa Valley report. For current publications see: http://www.sfei.org/napawatershed/historicalecology.htm HABITAT TYPE (Habitat_Type): This attribute describes the diverse array of historical habitats in south Santa Clara Valley including: [in Polygon layer - historical habitats] : Alkali Meadow Alkali Meadow/Tidal Marsh Ecotone Braided Channel Deep Bay/Channel Grassland Live Oak Savanna Mainstem Channel Perennial Freshwater Pond Shallow Bay/Channel Tidal Flat Tidal Marsh Valley Freshwater Marsh Valley Oak Savanna Vernal Pool/Swale Area Wet Meadow Willow Grove [in Polyline layer - historical creeks] Mainstem Channel (of Napa River) Historical Channel (Tributary to the Napa River mainstem) Floodplain Slough (Typically wide and shallow, and/or within a historical wetland) Paleochannel (A less well-defined, possibly prehistoric, drainage visible in aerial photos) PRIMARY AND SECONDARY SOURCE (Primary_Source, Secondary_Source): The major source materials used to map the feature are listed using, to the extent possible, standard textual citation form. Full bibliographic information can be obtained from the corresponding record in the Endnote bibliographic database and/or report bibliography. When a source directly contributed to the location of a feature, it was listed as a Primary Source; when it indirectly helped locate a feature, it was listed as a Secondary Source. Not all features have secondary sources. CERTAINTY ATTRIBUTES (InterpCert, Shape_Cert, Loc_Cert): Three distinct kinds of certainty are recorded: the certainty of our interpretation of the feature, its size/shape, and its location. Certainty of Interpretation The following certainty level codes are used in the feature class attribute (InterpCert): High (H): Feature definitely representative of conditions circa 1769-1850. Medium (M): Feature probably representative of conditions circa 1769-1850. Low (L): Feature possibly representative of conditions circa 1769-1850. Certainty of Size and Shape The following certainty level codes are used in the feature class attribute (Shape_Cert): High (H): Accurate source material that probably closely follows actual shape; estimated to be within 10% of actual area. Medium (M): Less accurate source material that probably generally follows actual shape; estimated to be between 50%-200% of actual area. Low (L): Inaccurate source material that may not follow actual shape; estimated to be between 25%-400% of actual area. Certainty of Location The following certainty level codes are used in the feature class attribute (Loc_Cert): High (H): Expected maximum horizontal displacement less than 50 meters. Medium (M): Expected maximum horizontal displacement less than 150 meters. Low (L): Expected maximum horizontal displacement less than 500 meters. NOTES: Direct and indirect quotes from data sources are included in this field when they were available. Other clarifying notes relating to evidence and methodology are included in this field as well As with any map or GIS layer, confidence or certainty varies geographically due to differences in source data or methods. This coverage provides direct information about the certainty level of different areas and features to allow the user to intelligently assess the applicability of the data for the chosen technical question.
