Title: Pacific Islands, Tutuila, American Samoa, IKONOS data, 2002
Short Name: tutuila_msi_metadata
Status: Completed
Publication Date: 2002-04-10
Abstract:

IKONOS imagery was purchased to support the Pacific Islands

Geographic Information System (GIS) project and National

Ocean Service's (NOS) coral mapping activities. One-meter

panchromatic and four-meter multi-spectral data were

purchased for each study area.

Purpose:

The Pacific Islands Geographic Information System (GIS) project

is a multiyear initiative designed to increase the use of GIS and

related spatial technology in the coastal resource management

programs of the Territories of American Samoa and Guam, the

Commonwealth of the Northern Mariana Islands (CNMI), and the

State of Hawaii. The project will focus on personnel, training,

equipment, software, data, and applications. Where appropriate,

other related activities in the region will be incorporated into

the effort.

Data Quality

Accuracy:

See Horizontal_Positional_Accuracy

Horizontal Positional Accuracy:

56 ground control points were used to determine the circular

error (CE) at a 90% confidence level. For Pacific Islands, Tutuila,

American Samoa, IKONOS data, 2002 the

circular error is 5.7 meters for the Multispectral data set.

Vertical Positional Accuracy:

Terrain correction adjusted the water height to equal the

true ellipsoid height of the water (sea level).

Completeness Report:

Compliance with the accuracy standard for the reprocessed imagery was ensured

by the placement of photo identifiable ground control points.

Conceptual Consistency:

Tests for logical consistency indicate that all row and

column positions in the selected latitude/longitude

window contain data.

Process Steps

Process Step 1

CC ID: 669072
Description:

Data Import and Color Merge: IKONOS Carterra Geo data can be

purchased in Geotiff and NITF formats. The horizontal error

for Geotiff imagery is @ 50 meters, while NITF imagery has

an error of @ 20 meters if the user has the software to read

the Rational Polynomial Coefficients (RPCs) from the NITF

header. Socetset, PCI geomatica, and ERDAS Orthobase Pro are

currently the only commercially available image processing

software packages that can read the RPCs.

The IKONOS images were processed using the PCI Geomatica

Orthoengine module. Projects were set up in Orthoengine

using the Satellite Orbital Modeling Math Modeling Method

with the General High Resolution Option. Separate projects

were created for the panchromatic and multispectral images.

IKONOS NITF formatted images were imported into PCI, then

ground control points (GCPs) were identified and selected.

The number of GCPs varies by image. Image to image tie

points (5-10 points per overlap area) were selected in areas

of overlap. USGS 10 meter DEMs were imported into

Orthoengine and checked for spatial accuracy. In some cases

the DEMs needed to be adjusted to fit the IKONOS imagery.

In addition, the DEMs were converted from a Mean Sea Level

datum to an ellipsoid. Elevations in areas over water were

adjusted upward to match the shoreline values in the ellipsoid

DEMs. The images were orthorectified to the adjusted DEMs.

After orthorectification, the images are color balanced if

necessary then and mosaicked. An error analysis was performed

on each mosaic by comparing the map coordinates of the ground

control points in the orthorectified mosaic to the original

GCPs. A circular error (at a 90% confidence level) was

determined and is reported in the accuracy section.

Ancillary data sets:

USGS 10 meter DEM, Ground control points were provided by the

NOAA National Geodetic Survey and the American Samoa Government.

Known Problems:

The USGS DEM for Tinian had to be adjusted in the X and Y directions to

match the IKONOS imagery.
