Title: C-CAP Commonwealth of the Northern Mariana Islands (CNMI), Rota 2005-2014 Land Cover Change Analysis
Short Name: ccap_rota_2005_2014
Status: Completed
Publication Date: 2018-02-10
Abstract:

This data set contains the 2005 and 2014 classifications of Rota, CNMI and can be used to analyze change. This data set utilized utilized 5 full or partial WorldView2 multispectral scenes and the 2005 high-resolution Rota C-CAP data set, which were analyzed according to the Coastal Change Analysis Program (C-CAP) protocol to determine land cover.

Purpose:

To improve the understanding of coastal uplands and wetlands, and their linkages with the distribution, abundance, and health of living marine resources.

Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 3; ESRI ArcCatalog 9.2.2.1350

Data Quality

Accuracy:

Attribute accuracy report does not exist

Horizontal Positional Accuracy:

12 meters CE90

Vertical Positional Accuracy:

There was no terrain correction in the geo-referencing procedure.

Completeness Report:

Data does not exist for all classes.

Many classes of from-to change never occurred in Rota, CNMI.

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: 716314
Description:

This dataset was created by NOAA's Ocean Service, Office for Coastal Management (OCM).

This dataset contains the classifications of 2005 imagery and 2014 imagery. It is used for change analysis between these years. The

attributes include a from-to change description category. There are

481 classes corresponding to the 481 possible from-to change combinations.

In this section of the metadata, the 2005 classification

procedure is described, then the 2011 change detection classification procedure is

described. Finally in the post-processing section, the process of combining

the maps to generate a spatial matrix of change is discussed.

Early Date (2005) Classification: This section outlines the classification procedure for the Rota, CNMI High Resolution C-CAP.

Pre-processing steps:

The Quickbird mosaic utilized for this project was provided from Digital Globe as an orthorectifed, georeferenced product and was consistent with the quoted 1:12000 spatial accuracy.

Field-Collected Data:

Training data was collected in the field between March 14th and 27th, 2008. Land cover observations were recorded by analysts. The referenced dataset went through a QA/QC procedure to ensure it met accuracy standards.

Classification:

Segmentation - Image segmentation was completed at multiple scales using the multispectral (2.4 m) imagery in order to group like spectral and textural objects within the imagery. For consistency, the associated impervious data set was incorporated into the segmentation layer as a boundary delimiter. Segments can share boundaries of an impervious surface, but can never overlap an impervious surface.

Automated Classification, Image segments are classified using a decision tree classifier in See5 software and an iterative nearest neighbor classifier in Definiens software. Nearest neighbor training data is collected through analyst interpretation or ancillary data sets and used to calibrate the classification algorithm.

Automated Classification Refinement - Models are built to refine or reclassify land cover areas by utilizing the wealth of attribute information linked to each segment within Definiens.

Classification Edits - As with any automated or semi-automated land cover classification there are often inconsistencies in the land cover map. The final step before map finalization was to remove inaccuracies through manual segment labeling as interpreted by an analyst.

Map Finalization - Sanborn used independent reviewer's comments to further refine the land cover map.

Process Step 2

CC ID: 716315
Description:

Late Date (2011) Classification:

This section outlines the classification procedure for the Rota, CNMI High Resolution C-CAP.

Pre-processing steps:

The Worldview-2 mosaic utilized for this project was provided from United States Department of Agriculture, Natural Resources Conservation Service as an orthorectifed, georeferenced product.

Field-Collected Data:

Training data collection was completed on June 22, 2017. Land cover observations were recorded by analysts and georeferenced photographs were taken in a variety of land cover types.

Classification:

Segmentation - Image segmentation was completed at multiple scales using the multispectral (2.4 m) imagery in order to group like spectral and textural objects within the imagery. For consistency with previous land cover mapping efforts, the generation of objects was partially constrained by the 2005 NOAA Rota C-CAP land cover product.

Classification- The image segements from the 2014 Worldview-2 imagery were overlaid on imagery and analysts counducted a visual analysis to identify areas of change.

Map Finalization - NOAA OCM performed two rounds of internal product review and one round of external review with independent partners. Reviewer comments were incorporated to further refine the final land cover product.

Post-Processing Steps:

A GIS matrix algorithm was run with 2005 and 2014 datasets as inputs. The algorithm generates

a from-to file where each combination is uniquely labeled from 1 to 481.
