Stereo Analyst For Arcgis 102 Li
Stereo Analyst for ArcGIS 10.2 Li: A Powerful Tool for Stereo Mapping
Stereo mapping is the process of creating and editing 3D features from stereo imagery, which are two overlapping images taken from different perspectives. Stereo mapping can be used for various applications, such as parcel editing, creating simple 3D buildings, and measuring distances and heights. However, stereo mapping requires high-quality stereo imagery with accurate georeferencing and orientation information, as well as a specialized software that can display the stereo pairs and support the feature extraction workflow.
One of the software that can meet these requirements is Stereo Analyst for ArcGIS 10.2 Li, an extension for ArcGIS Desktop that enables stereo viewing and feature collection in ArcMap. Stereo Analyst for ArcGIS 10.2 Li is compatible with a wide range of stereo data sources, such as satellite, aerial, ADS, and drone imagery. It also supports various stereo viewing modes, such as active shutter eyewear, red-cyan anaglyph glasses, or passive polarized glasses. Moreover, Stereo Analyst for ArcGIS 10.2 Li integrates seamlessly with the ArcGIS platform, allowing users to access and edit geodatabase features directly in the stereo map.

How to use Stereo Analyst for ArcGIS 10.2 Li
To use Stereo Analyst for ArcGIS 10.2 Li, users need to have a license for ArcGIS Desktop 10.2 or higher, as well as a license for the Image Analyst extension. Users also need to have a stereo-ready monitor and a suitable pair of glasses, depending on the stereo viewing mode they prefer.
The first step to use Stereo Analyst for ArcGIS 10.2 Li is to prepare the stereo imagery. The input for the stereo map can be either a mosaic dataset that manages a collection of stereo models, or a single stereo model. A stereo model is two images that have an overlap and an intersection angle that can form a pair for stereo viewing; the two images must have correct georeferencing and orientation information. The quality of the stereo models can affect the accuracy of the features collected.
If the images have not been geometrically corrected for stereo viewing, users can use the Ortho Mapping tools in ArcGIS Desktop to perform block adjustment and generate an adjusted mosaic dataset. If the images have been geometrically corrected, users can create a mosaic dataset and add the images using the appropriate raster type. Then, users need to run the Build Stereo Model tool to create the stereo pairs.
The second step is to create a stereo map document in ArcMap. Users need to add the mosaic dataset or the single stereo model as a layer in the map document, and enable the Stereo Map mode from the Stereo Analyst toolbar. Users can also add other layers, such as basemaps or existing features, to enhance the stereo map.
The third step is to view and navigate the stereo imagery. Users can use the Stereo Viewer window to adjust the display settings, such as brightness, contrast, zoom level, and parallax. Users can also use the navigation tools, such as pan, rotate, tilt, and fly, to explore the stereo scene.
The fourth step is to collect and edit 3D features in the stereo map. Users can use the editing tools in ArcMap to create point, line, or polygon features based on the stereo imagery. Users can also use snapping and measurement tools to improve the accuracy and quality of the features. The output of the feature creation or editing session is saved directly to a geodatabase and can support multiuser concurrent editing workflows.
