A comprehensive discussion over 3D Photogrammetry Software for aerial photogrammetry work. Two software are essential, one for 2d data editing and another for 3d photogrammetry data capture.
CAD Software for 2d and 3d work Microstation:
-Micro Station is a generic computer-aided design (CAD) system.
-MicroStation is a CAD software product for 2- and 3-dimensional design and drafting, developed and sold by Bentley Systems.
-MicroStation is the platform architectural and engineering software package developed by Bentley Systems, Incorporated.
- Among a number of things, it generates 2D/3D vector graphic objects and elements.
-Current version is MicroStation V8i. Micro Station is used in various industries, and has been popular within the mapping industry for many years due to its inherent ability to handle 3-dimensional data with ease.
-It serves as backend Photogrammetry software. Micro Station manages a database of graphical elements, known as design file, or DGN file for short. Commonly used graphical elements in mapping applications include:lines, shapes, curves , arcs , symbols ,text
-Its native format is the DGN format, though it can also read and write a variety of standard CAD formats including DWG and DXF as producing media output in such forms as rendered images (JPEG and BMP), animations (AVI), 3D web pages in Virtual Reality Modeling Language (VRML, and Adobe Systems PDF).
-MicroStation was used in the engineering and architecture fields primarily for creating construction drawings.
-It can provide specialized environments for architecture, civil engineering, mapping, or plant design, among others.
-In 2000, Bentley made revisions to the DGN file format in V8 to add additional features like Digital Rights and Design History - a revision control ability that allows to reinstate previous revisions either globally or by selection, and to better support import/export of Autodesk's DWG Format.
CAD Software for 2d and 3d work Auto Cad:

CAD Software for 2d and 3d work Auto Cad:
-AutoCAD is a CAD software (Computer Aided Design or Computer Aided Drafting) application for 2D and 3D design and drafting, developed and sold by Autodesk, Inc. Initially released in late 1982, AutoCAD was one of the first CAD programs to run on personal computers, and notably the IBM PC.
-AutoCAD supports a number of application programming interfaces (APIs) for customization and automation. These include Auto LISP, Visual LISP, VBA, .NET and ObjectARX. ObjectARX is a C++ class library, which was also the base for products extending AutoCAD functionality to specific fields, to create products such as AutoCAD Architecture, AutoCAD Electrical, AutoCAD Civil 3D, or third-party AutoCAD-based applications.
-AutoCAD's native file format, DWG, and to a lesser extent, its interchange file format, DXF, have become de facto standards for CAD data interoperability.
CAD Software for 2d and 3d work Leica Photogrammetry Suite (LPS):
-AutoCAD's native file format, DWG, and to a lesser extent, its interchange file format, DXF, have become de facto standards for CAD data interoperability.
CAD Software for 2d and 3d work Leica Photogrammetry Suite (LPS):
-Leica Photogrammetry Suite (or LPS) is a photogrammetry software application for performing photogrammetric operations on imagery and extracting information from imagery.
-LPS is significant because it is a leading commercial Photogrammetry application that is used by numerous national mapping agencies, regional mapping authorities, various DOT, as well as commercial mapping firms.
-LPS is generally used for the processing of raw imagery through to the creation geospatial data products such as digital terrain models, 3D features, and digital orthophoto.
-In addition to this workflow, LPS supports 3D feature extraction, radiometric adjustment, and a number of additional digital image processing capabilities available from ERDAS IMAGINE, which is included with LPS. LPS is software developed by Erdas Corporation used as a front end for 3d feature extraction with the associated hardware like infrared emitter and 3d mouse.
-It is also having a Pro600 tools which is used as a plug-in with Microstation for Planimetric feature extraction. In addition to the workflows above, LPS also supports the following applications:
-Satellite Photogrammetry
Direct Georeferencing: ground control (GCPS) is not used because the aircraft is equipped with Airborne GPS and IMU systems. This is an emerging workflow that is suitable for remote area mapping.
Close-Range Photogrammetry
CAD Software for 2d and 3d work Pro600 tool:
The LPS PRO600 module consists of flexible, easy-to-learn CAD-based tools for large scale digital mapping using stereo imagery. It is a sophisticated package for interactive feature collection and editing in the MicroStation GeoGraphics environment.
Features:
• Cartographic presentation tools such as line patterning, polygon hatching, symbology, contour annotation, slope hachure and manuscript grid placement .
• Extensive feature coding capabilities.
• Display graphics in Micro Station views as well as LPS stereo image view.
• Multiple collection modes and tools enhance productivity.
• Parallel line generation with up to 20 parallel lines simultaneously.
• Button mapping using input devices such as Topo Mouse, Immersion mouse or system mouse. Automatic periodic design file backup.
• Undo and redo • Ground control point utility allows plot of ground control points as annotated symbols.
• Read ORIMA, SOCET SET and plain text ground control point files
• Data editing including contour rounding, centerline generation.
The PROLPS Driver from Leica Geosystems Geospatial Imaging is a software application that provides a direct link between the Leica Photogrammetry Suite and MicroStation V8 from Bentley Systems, Inc.
The PROLPS Driver is a component of the PRO600 suite of applications for MicroStation V8.
The PROLPS Driver provides a link to the Leica Photogrammetry Suite through its use of a stereo viewer window called the View Plex. Using this window, the PROLPS Driver provides an additional, 3D stereo view of imagery together with design file vector graphics, fully integrated within the MicroStation environment.
The View Plex allows you to view stereo pairs of imagery that have been prepared using the Leica Photogrammetry Suite Project Manager.
Working closely with the PROLPS Driver, the core functionality of PRO600 is provided by the PROCART application. PROCART provides a project manager utility that lets you organize your MicroStation design files in a project-based manner.
Finally, PROCART provides a number of data editing and visualization tools that complement those of Micro Station and aid you in the creation of the finished product.
Along with this there are some more photogrammetry software ’s available in the market for Photogrammetry.
