The tools you need for Imagery !

GIS users can now rely upon GeoImaging Tools for ArcGIS®, offering
accurate and efficient means of correcting raw imagery and opening
new doors for the integration of remotely sensed imagery into GIS
workflows. PCI Geomatics are the imagery experts with over 28 years of experience in building image-processing software.

Our technology is known for its rigorous, automated and accurate
optical and SAR satellite image corrections, providing imagery based
layers that can be used to derive new information in your GIS environment.

Built as an extension to ArcGIS 10, PCI’s GeoImaging Tools for
ArcGIS enables ArcGIS users to integrate accurate imagery into their
workflows. Users have the option to save the correction parameters
into the Raster Processing Definition (RPDef) format, reducing data duplication by using PCI’s powerful sensor model
definitions!

■■ Improve the registration accuracy through the collection of control points

■■ Correct many images simultaneously using block bundle adjustments - using tie-points to achieve even
higher levels of registration accuracy

■■ Perform accurate change detection and feature extraction operations in the GIS using imagery corrected using GeoImaging Tools for ArcGIS

 

Supported sensors
With GeoImaging Tools, you can now access a wide variety of optical and SAR satellites, which can all be corrected
and ingested into ArcGIS. The following table shows a partial list of those sensors supported:

Satellite Sensors			Radar Sensors
ALOS-AVNIR	HJ-1A	Landsat-7	ASAR
ALOS-PRISM	HJ-1B	QuickBird	RADARSAT-1
ASTER	Ikonos	Rapideye	RADARSAT-2
CARTOSAT-1	IRS-LISS	Spot-4	TerraSAR-X
CBERS	Kompsat-2	Spot-5
GeoEye-1	Landsat-5	WorldView-1/2

 

How the software integration works

Version 2.0 of GeoImaging Tools for ArcGIS is created as an extension for ArcGIS 10. To use it, users must have
ArcGIS 10 and Python 2.6 installed on their system. The capabilities are implemented as a series of tools within the
GeoProcessing toolbox, which can be linked together to form a repeatable workflow.

Ingest Raw Scenes - Ingests raw satellite scenes along with metadata and model information

■■ Refine Raw Scenes with GCPs - Collects Ground Control Points (GCPs) from various reference sources and uses them to refine the nominal math model

■■ Refine Raw Scenes with TPs - Collects Tie Points (TPs) from a set of overlapping scenes and refines the math
model

■■ Write RPDefs - Creates Raster Process Definition (RPDef) files from input raster files that have a math model
segment

Applications

Poor imagery registration limits the GIS user’s ability to efficiently perform simple tasks, like change detection and feature extraction. GeoImaging Tools for ArcGIS will improve users’ abilities in the following areas:

■■ Urban Change Detection
■■ Deforestation Studies
■■ Map Updating
■■ Emergency Management

 

GeoImaging Tools for ArcGIS key features/benefits
