Description:
Abstract:
This is a final impervious surface layer ready for distribution through NOAA CSC. The data set is an inventory of impervious surfaces for the Island of Island of West Manua, American Samoa, for the year 2005. Impervious surfaces prevent infiltration of precipitation into the soil, disrupting the water cycle and affecting both the quantity and quality of water resources. Impervious surfaces include manmade features such as building rooftops, parking lots and roads consisting of asphalt, concrete and/or compacted dirt. This data set utilized 4-band Quickbird scenes which were processed to detect impervious features of the Island of West Manua in American Samoa.
Purpose:
To create a baseline inventory of impervious surfaces which can be utilized by state and local resource managers to assess the impacts precipitation events on water quality and flooding.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
No automated accuracy was performed during or at the end of the impervious map production process. Quality Control was carried out by cross-examination East Manua Impervious map with the Quickbird image. Errors of omission and commission were corrected. All impervious objects sized smaller than the Minimum Mapping Unit (.05 sq m) were ignored and not included in East Manua impervious map.
Logical_Consistency_Report:
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.
Completeness_Report: Data set is complete.
Positional_Accuracy:

Process_Description:
This dataset was created by The NOAA Coastal Services Center. The impervious surface classification is based on Quickbird imagery. The study area for the project was the Island of Island of West Manua, American Samoa. Automated Classification: The automated portion of the classification methodology utilized the Feature Analyst extension for ArcGIS. Feature extractions were performed by providing the algorithm with examples of impervious features to extract from the Quickbird imagery. Once the extractions were completed an internal review was performed by C-CAP analysts at NOAA CSC. Classes 0 - Pervious 1 - Impervious

Process_Description:
Manual editing and modeling: Errors or areas that could not be consistently extracted from the imagery were resolved through manual edits and using ancillary data sets. In some areas of the islands, impervious surface features are obscured by clouds, shadows or tree canopy. For these types of issues NOAA CSC relied on ancillary imagery and vector data. Due to spectral confusion between impervious surfaces and other features such as bare land manual editing was performed in ArcMap to correct commission errors within the map. The same technique was used to capture missing impervious features that could not be derived from ancillary data sources.
