PCI Geomatica Prime (PCI geographic information professional edition) PCI geomatica prime contains all the functions of PCI geomatica foundation (see the previous section). In addition, PCI Modeler, EASI and FLY have been added! And an algorithm library. Geomatica Prime is a powerful and low-cost solution, which provides tools for image geometric correction, data visualization and analysis, and professional standard map making.

PCI productivity tool (PCI software is specially designed by PCI company to improve the productivity and efficiency of PCI software. Its main function is to provide users with a series of functions for automatic or batch operation. This software is an extension of PCI GEOMATICA PRIME or FUNDAMENTALS. It mainly provides automatic image mosaic function and automatic collection function of homonym points for aerial photos, optical satellite images and radar satellites of ORTHOENGINE series products. At the same time, it provides image control point library and library management functions.

PCI AIRPHOTO MODEL (PCI aerial orthophoto processor of PCI geographic information system) is a powerful orthophoto correction tool, which is used together with PCI Geomatica Foundations or Geomatica Prime module. The module uses a special algorithm model to make scanned photos or photos obtained by digital cameras into accurate orthophoto maps. The generated images can be converted into various file forms and can be used as data sources for many GIS/CAD/MAP software. At the same time, users can choose additional DEM automatic extraction, 3DVIEW and 3D feature extraction module (OrthoEngine Airphoto DEM) to build their own digital photogrammetry software package.

The software has the following functions: project file establishment (including automatic frame mark acquisition), direct geographic reference coordinate information reading (supporting GPS/INS, external orientation input and text control point input), internal orientation of standard camera or digital camera, control point and homonym point acquisition, regional beam adjustment, data detection, residual report and various forms of DEM import functions, orthographic image generation, mosaic and output project report.

PCI satellite model (satellite orthophoto processor of PCI geographic information system) This module is mainly used for SPOT 1, 2, 3,&; 4. Landsat 4 and 5; 7. IRS 1A/B/C/D, AVHRR, IKONOS (NITF-RPC with fast positioning capability), ASTER, RADARSAT, JERS 1, ers1&; 2. Orthorectification of satellite images. This module contains the calculation model of the above sensors (allowing users to establish new sensor calculation models), and corrects the distortion caused by satellite attitude and position, terrain change and projection.

The module mainly includes the following functions: project establishment, special radar algorithm model that can accurately correct radar images without (or a small number of) ground control points, collection of control points and points with the same name, regional beam adjustment, residual report and various forms of DEM import functions, mosaic, orthophoto generation, especially for radar images, and also has the functions of setting and generating orthophoto while filtering images, importing data according to voltage or power, importing images and so on.

Accuracy: In general, there are accurate DEM and GCP, and the accuracy is 1/3 pixels.

PCI IKONOS MODELS ((PCI IKONOS satellite orthophoto processor for PCI geographic information system) Ortho engine Ikonos specially designed by PCI company for Ikonos contains the mathematical model of space sensor, which can generate high-precision orthophoto from ikonos data and correct the image distortion caused by satellite attitude, terrain fluctuation, earth curvature and cartographic projection. Using ground control points and points with the same name to calculate and generate orthographic images. If there is no control point, you can also use the image corner coordinates provided by tape and CD to calculate. The region of interest can be cut out from the uncorrected image, so that orthorectification can be performed only in the set region, and a smaller orthorectification image can be generated to improve the processing speed. Batch processing can be used to batch images. You can choose to delete the corrected original image to save hard disk space. If no DEM is provided, the system will default the processing area to plane and use the average elevation to correct the image. Users can use elevation scale and elevation offset to modify DEM elevation values. Adjustable cache improves processing speed. The nearest pixel, bilinear interpolation, bicubic convolution, 8 points, 16 points and sin x/x algorithm can be selected for resampling.

PCI automatic DEM extraction (PCI automatic DEM extraction tool for aerial photos and optical satellite images of PCI geographic information system) This software package is attached to PCI Geomatica Foundations or Geomatica Prime module, and can automatically extract DEM from aerial photos, SPOT, IRS and ASTER images. The software allows users to select absolute and relative heights. If absolute elevation is selected, GCP and feature points with the same name must be collected. The generated DEM can be output in various formats. China 3S bar

The main functions include: epipolar image generation, automatic DEM extraction, manual editing of geocoded DEM and 2D DEM, error point elimination and interpolation.

PCI Automatic RADARSAT DEM (PCI automatic DEM extraction tool for radar satellite images of PCI geographic information system) This software package is attached to PCI Geomatica Foundations or Geomatica Prime module, and can automatically extract DEM from radar satellite images. The software allows users to select absolute and relative heights. If absolute elevation is selected, GCP and feature points with the same name must be collected. The generated DEM can be output in various formats.

The main functions include: epipolar image generation, automatic DEM extraction, manual editing of geocoded DEM and 2D DEM, error point elimination and interpolation.

PCI 3D viewing and editing (PCI OrthoEngine 3D viewing and editing) is attached to Geomatica Fundamentals or Geomatica Prime, which provides users with 3D display and feature extraction (vector editing) functions, mainly for aerial photos, SPOT, IRS- 1 and RADARSAT images. It also includes 3D DEM editing.

This software needs special auxiliary hardware to work-polarized glasses/display.
