For PCI companies that have been committed to providing comprehensive solutions to the geoscience community for more than 20 years, they always adhere to the principle of being one step ahead. Geographic consultation is always changing, and geographic consulting software is at the forefront of change.
- Today, as the breadth and depth of user needs continue to widen and deepen, more and more people hope that software is a good tool that can meet all the needs of users. Due to the correct grasp of this point, after 4 years of hard work, the PCI company integrated the original four product series together to produce a simple and smart work platform ---- PCI GEOMAITCA. At each level of depth, this series of products can meet the needs of users at this level for remote sensing image processing, photogrammetry, GIS spatial analysis, and professional mapping functions as much as possible, and users can conveniently use the same application interface. Get their work done. Prior to this, users need to use multiple software to implement, and need to face multiple software distributors, multiple software technical support, multiple training, maintenance of multiple software, and had to invest considerable effort to Data conversion between multiple data formats.

- The professional radar processing radar has the ability to acquire data 24 hours a day, 7 days a week, and its unique advantages in many fields such as marine, snow, vegetation, geology, and military applications, which has attracted universal attention from all countries. It is the era of radar remote sensing. If you notice how many spaceborne remote sensing systems are currently operating, how many are SAR systems and how many are in the plan, you will know that this conclusion is appropriate. The PCI company has firmly grasped this development trend and has always maintained an absolute world leading position in the field of radar data processing. To obtain SAR images, it takes a very complicated imaging process. It took Canada's MDA company twenty years to complete the SAR imaging software and hardware system. Nowadays, with the SARP provided by PCI, all the functions that a huge system that only a ground station can equip can be realized. Purchasing raw signal data can save a lot of money, and users can flexibly control the imaging process according to their application purposes, that is, the enhanced suppression and expression of control information, which avoids the flow of products from ground stations that are not suitable for special application purposes Case.
- PCI's APP provides fine imaging processing algorithms for marine applications, point target detection (military applications), and special configuration situations (such as long-distance imaging at large viewing angles). This product is advanced because many experts in the field of radar remote sensing applications I just realized that in order to continue the application, we must start from the beginning (imaging). PCI can already provide a complete product. In terms of conventional SAR image processing, the software provided by PCI is characterized by providing a complete solution to the problem of geometric correction of SAR images, and also provides rich filtering, texture analysis, radiation correction and calibration, and change detection. And image quality evaluation tools. Another software package provided by PCI can be used to extract DEM from stereo image pairs of Radarsat. This is the only practical software in this field. It is more difficult to extract DEM from radar stereo images than to extract DEM from optical stereo images. The reason is that the radar image has complex features, and the matching of points with the same name requires complex mathematical methods.
