Stereo Analyst for ArcGIS
Stereo Analyst for ArcGIS empowers Geographic Information Systems (GIS) professionals to use imagery for the direct collection and revision of feature data to a GIS. Stereo Analyst for ArcGIS is the first stereo feature collection product entirely built on a GIS, for a GIS, to feed a GIS. Stereo Analyst for ArcGIS accurately transforms the visual contents of an image into reliable GIS data.
Our Changing World
As our earth changes, so does the information needed to understand it. Images serve as a permanent record of features, relationships, processes and behavior. Stereo Analyst for ArcGIS accurately converts the contents of imagery into reliable feature data, which can then be used within the context of a GIS to establish relationships, model processes and understand behavior.
Accurate Feature Data From Imagery
Imagery plays a vital role in creating and sustaining a reliable GIS. Using traditional photogrammetric techniques, aerial photographs were used to create cartographic and topographic maps. These base maps were subsequently used as a traditional basis for digitizing the feature data that currently live in most GIS databases today. The traditional workflow required to transform an image to GIS data is tedious, expensive, and time consuming. Stereo Analyst for ArcGIS provides a direct 'image to GIS' approach to obtain reliable feature data from imagery.
'GIS-Ready' Imagery: Oriented Images
'GIS-ready' images, also referred to as oriented images, now serve as the basis for collecting and revision feature data in a GIS. Oriented images are raster datasets with associated intelligence (i.e. metadata). The metadata associated with an oriented image describes the complete relationship between the sensor, the image and the ground, thereby empowering the user to collect reliable data from imagery. Metadata is important since it accounts for and eliminates the variables that may contribute to error in data.
Oriented images are created using photogrammetric techniques by IMAGINE OrthoBASE and SOCET SET. Satellite images provided by companies such as Space Imaging and DigitalGlobe are oriented images, which can be used directly within Stereo Analyst for ArcGIS.
Stereo Analyst for ArcGIS allows the GIS professional to directly create and maintain feature data in a GIS using oriented imagery.
Feature Editing in Stereo Analyst for ArcGIS
Stereo Analyst for ArcGIS utilizes the editing tools provided by ArcMap and allows GIS professionals to collect new and revise existing feature datasets in 3D using oriented images. Oriented images created by ERDAS IMAGINE, IMAGINE OrthoBASE or Image Analysis for ArcGIS can be directly added to ArcMap and used for accurate feature collection. SOCET SET projects and support files can also be converted to oriented images.
Feature datasets and feature classes stored within a Geodatabase can be directly accessed and updated using oriented imagery. Stereo Analyst for ArcGIS provides tools to accurately transform existing datasets and a Geodatabase to represent 3D reality. Multiple ergonomic digitizing devices are supported to increase the efficiency and productivity of feature collection.
