Title: C-CAP Santa Cruz 2001 era High Resolution Land Cover Metadata
Short Name: santa_cruz_2001_hr_ccap_4m
Status: Completed
Publication Date: 2008-07-15
Abstract:

This dataset represents land cover for the San Lorenzo River basin in Santa Cruz County, California derived from high resolution imagery. The land cover features in the imagery were classified to the Coastal Change Analysis Program (C-CAP) classification scheme. Land cover data was derived through a combination of image processing methods including image segmentation and rule-based techniques available from the eCognition software package, and more traditional "cluster-busting" methods. in 2008, additional processing was applied to the land cover to make the data set more consistent with what is being distributed as a part of the High Resolution C-CAP effort.

Purpose:

This high resolution land cover dataset was developed as part of the "Salmonid Recovery Planning Information Resource for San Mateo and Santa Cruz Counties" project. The intended use of this dataset is assist in the determination of suitable habitat and conditions for salmonid recovery and restoration. As part of the High Resolution C-CAP effort it can alos be used to improve the understanding of coastal uplands and wetlands, and their linkages with the distribution, abundance, and health of living marine resources.

Data Quality

Accuracy:

No quantitative accuracy assessment has been performed for this data set. It was reviewed by analysts at NOAA Coastal Services Center using high resolution digital aerial photography. The data set was also reviewed by local experts in the Santa Cruz area.

Horizontal Positional Accuracy:

12 meters CE90

Completeness Report:

Data does not exist for all classes.There are no pixels representing class 7 (Pasture/Hay), 15 (Estuarine Forested Wetland), 16 (Estuarine Scrub Shrub), 18 (Estuarine Emergent), 24 (Tundra), 25 (Perennial Ice/Snow), 26 (Dwarf Scrub - Alaska specific class), 27 (Sedge/Herbaceous), and 28 (Moss - Alaska specific). Developed classes have been altered to exclude the percentage breakdown of impervious surfaces as the breakdown is not appropriate for high resolution mapping (Developed High Intensity (2), Developed Medium Intensity (3), and Developed Low Intensity (4) are reduced to Impervious Surfaces (Class 2)). Mixed Forest (11) was also determined not be appropriate for this map since no mixed pixels existed at this spatial resolution.

Conceptual Consistency:

Tests for logical consistency indicate that all row and column positions in the selected latitude/longitude window contain data. Conversion and integration with vector files indicates that all positions are consistent with earth coordinates covering the same area. Attribute files are logically consistent.

Process Steps

Process Step 1

CC ID: 631622
Description:

Initial field sampling to identify features in the field that corresponded to the modified C-CAP classification scheme. GPS units were taken into the field, along with laptops equipped with FieldNotes software, to collect and record reference data points across the study area.

Process Date/Time: 2002-06-01 00:00:00

Process Step 2

CC ID: 631623
Description:

Special transformations of IKONOS imagery were derived to increase the data set dimensionality. This was achieved by calculating the Normalized Difference Vegetation Index (NDVI), Principal Component Images (PCA), and Tasseled-Cap Brightness, Greenness & Wetness images from the raw multi-spectral IKONOS imagery. These images were compiled using the layer stack operation in ERDAS Imagine 8.5 to produce one image with multiple band layers.

Process Date/Time: 2002-06-01 00:00:00

Process Step 3

CC ID: 631624
Description:

Classifications techniques were performed on all four IKONOS layer-stacked scenes using eCognition and ERDAS Imagine 8.5 software. Image segmentations derived from the imagery were used to perform supervised classifications with eCognition. Preliminary classifications were then exported from eCognition as ERDAS Imagine files (.img) to be further processed in Imagine 8.5.Each class from the exported eCognition classifications were used as individual "masks"in Imagine to help refine the overall classification. This refinement was achieved by iterative isodata clustering, or "cluster-busting," on each masked class image. All individual class images were then recoded and merged to represent the modified C-CAP classification scheme.

Process Date/Time: 2002-06-01 00:00:00

Process Step 4

CC ID: 631625
Description:

The final step in the creation of the land cover data involved the use of hand editing. This approach involved the use of ancillary data sources in conjunction with the IKONOS data set. This methodology was employed to increase the accuracy of rare classes not easily derived from the IKONOS imagery alone.

Process Date/Time: 2002-06-01 00:00:00

Process Step 5

CC ID: 631626
Description:

Land cover classes were recoded to match current land cover scheme. A new set of image objects were derived from the IKONOS MS imagery using a scale factor of 50. The existing recoded land cover was summarized using the image objects as zones. The image objects were labeled using the zonal majority land cover.

Process Date/Time: 2008-06-09 00:00:00

Process Step 6

CC ID: 631627
Description:

The impervious surface class from the original land cover were refined using a clump and eliminate to reduce speckle in the map. Roads data were also burned in where incomplete or obscured roads existed. The new impervious surface class was inserted into the map derived from process step 5.

Process Date/Time: 2008-06-12 00:00:00

Process Step 7

CC ID: 631628
Description:

The final map was then manually edited by NOAA OCM analysts.
