What are the main functions of Erdas software?

ERDAS IMAGINE is a remote sensing image processing system developed by American ERDAS company. With advanced image processing technology, friendly and flexible user interface and operation mode, widely used product modules, model development tools for different levels of users and high RS/GIS (Remote Sensing Image Processing and Geographic Information System) integration function, it provides users in remote sensing and related application fields with rich content and powerful image processing tools, which represents the future development trend of remote sensing image processing system.

As a remote sensing software company, ERDAS was founded in 1978 and headquartered in Atlanta, Georgia, USA. Since its establishment, the company has been committed to the development, application and service of remote sensing processing system technology, opened up the global market in the field of remote sensing, achieved great success, and maintained a sustained and steady increase in profits in the past 20 years. At present, ERDAS has developed into the largest professional remote sensing image processing software company in the world, with more than 65,438+000 users in more than 60,000 countries and a market share of 46%, ranking first in the global remote sensing processing software market and ninth in the GIS software market. In June, 2003, in the evaluation of remote sensing image system of Passfind project organized by NIMA and other authoritative organizations, after five years, it won the first place in nine projects in 1 1, and finally ranked first in comprehensive function and cost performance, especially in the field of three-dimensional visual analysis. Since getting financial support from Leica in mid-2002, the development of ERDAS IMAGINE software has been smoother and faster, and more new functions and algorithms have been added to the new version. A series of measures not only give full play to the current investment of users, but also escort the future product development. According to the company's product development plan, a new generation of remote sensing image processing system (9th edition) based on COM and online image processing services will come out, which will provide users with more powerful systems and means and make development and expansion more convenient.

ERDAS company's excellent IMAGINE GIS software solution has always been a pioneer in the industry. Its software processing technology covers the input/output of image data, image enhancement, correction, data fusion, various transformations, information extraction, spatial analysis/modeling, expert classification, ArcInfo vector data update, digital photogrammetry and 3D information extraction, hard copy map output (drawing output in 3D landscape realizes a large number of clear paper maps that what you see is what you get) and radar data. Imagine that the software can support all UNIX systems, as well as Microsoft Windows 2000 Professional (which requires Pack 2) and Windows XP Professional operating systems of PCs. Its application fields include: scientific research, environmental monitoring, meteorology, oil and mineral exploration, agriculture, medicine, military (digital geography battlefield, interpretation, etc. ), telecommunications, cartography, forestry, natural resources management, public facilities management, engineering, water conservancy, ocean, surveying and mapping, urban and regional planning. Through strategic cooperation with ESRI, a famous GIS manufacturer, ERDAS has developed two extension modules, namely image analysis and Stereo Analyst, and the IMAGINE series software fully integrated with GIS, based on ArcView GIS V8.x, to provide users with integrated GIS/RS solutions.

*ERDAS IMAGINE product suite: This is a complete product suite, which is used for image drawing, image visualization, image processing and advanced remote sensing technology.

*ERDAS IMAGINE extension module: ERDAS IMAGINE is provided to users in a modular way, so that users can reasonably choose different functional modules and their different combinations according to their own application needs and funds, tailor the system, make full use of software and hardware resources, and meet users' professional application needs to the maximum extent.

*ArcGIS extension module: This is an extension module that is convenient for ArcGIS users to analyze and process geographic images.

Lps (Leica Photography Suite)-Leica Remote Sensing and Photogrammetry System is a series of software products suitable for various digital photogrammetry workstations. It provides an accurate and production-oriented photogrammetry tool for the wide application of earth space images. LPS can process images of various formats from various aerospace sensors, including black and white, color and multispectral digital images with up to 16 bits. LPS can meet all kinds of photogrammetry requirements from original photos to line-of-sight analysis. It provides a wide range of application options for image, ground control, orientation and GPS data, vector and image processing, so it is flexible and simple to operate. LPS can provide hundreds of coordinate systems and map projection options to meet the different needs of users.

The LPS digital photogrammetry software system includes the following six software modules and four extended software modules.
