This data set consists of land derived from scanned black and white aerial photographs and was analyzed according to the Coastal Change Analysis Program (C-CAP) protocol to determine land cover. This data set utilized 21 full historic scenes that were processed to detect C-CAP land cover features on Saipan, CNMI.
To create a baseline inventory of land cover features which can be utilized by state and local resource managers.

Completeness Report
Data does not exist for all classes.
There are no pixels representing class 7 (Pasture/Hay), 9 (Deciduous Forest), 11 (Mixed Forest), 16 (Estuarine Forested Wetland), 17 (Estuarine Scrub/Shrub Wetland), 18 (Estuarine Emergent Wetland), 19 (Unconsolidated Shore), 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 (Class 2)).
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.
This dataset was created by Sanborn (www.sanborn.com).
This version of the classification is the High Resolution Land Cover (1945-era) for the Island of Saipan , CNMI.
This section outlines the classification procedure for the Island of Saipan , CNMI High Resolution C-CAP. Scanned historic black-and-white images from 1945 were used in a semi-automated methodology to detect change (retroactive) from 2005 QuickBird imagery. The mapping approach used image segments derived from the mosaicked 1945 imagery and the 2005 land cover classification which were analyzed and categorized as changed/not changed. Once changes were identified, they were modeled into the 2005 classification to create the 1945 classification. Pervious features were mapped using a 0.5 acre minimum mapping unit (MMU), excepting some small features of historic interest.
Pre-processing steps:
The historic 1945 imagery was provided as scanned black-and-white unmosaicked tiffs. The tiffs were georectified using the 2005 QuickBird imagery as reference and subsequently mosaicked. Due to parallax problems with the high relief on the island, isolated shifts remained in the completed mosaics, which were accounted for in the subsequent steps.
Classification:
Segmentation - Image segmentation was completed at multiple scales using the 1945 mosaic, a texture band derived from the mosaic, and the 2005 land cover classification as a boundary layer. The segments were created using the MMU of 0.5 acre as an approximate minimum size threshold.
Automated Classification - Image segments were classified using a decision tree classifier in See5 software into forested and non-forested categories only, using training data collected from the 1945 imagery and analyst interpretation. The result was then compared to and differenced with the 2005 land cover classification to provide a preliminary change mask. This was intended only as a broad guide to landscape changes
Manual Change Interpretation and Classification - Analysts, using the preliminary change mask, scanned the imagery (both 1945 and 2005) for changes in the land cover. These changes were put into the change mask, with the segment often serving as land cover change boundaries. These boundaries were also manually changed where necessary. Those impervious surfaces that existed in 1945 but not in 2005 were edited in using raster editing methods. Once complete, the 1945 change mask was compared to/differenced with the 2005 classification to drop out any unchanged pixels. This left only those pixels and areas changed between 1945 and 2005. The change pixels were modeled into the 2005 classification to create the 1945 land cover classification.
Map Finalization - Sanborn used independent reviewer's comments to further refine the land cover map.
