We are Geospatial Data Processing Service Providers


As a GIS data analysis service provider, Feiyan Remote Sensing​ has carried out aerial photography tasks in Quanjiao and Langxi counties of Anhui Province, and formed DEM and DSM through data processing.

In this project, the aircraft carrying VQ-780II and VQ-1560i aerial photography for flew 4 sorties.The obtained LiDAR point cloud data covered about 2618km²in Quanjiao and Langxi counties, and the laser point cloud data was better than 1pts/m². Eventually, the results are based on 2m×2m grid digital elevation model (DEM) and digital Surface model (DSM).


The preprocessed point clouds were classified automatically and manually, and the surface water area line with elevation information was taken as the feature line. After data processing, digital surface model(1:10000) and digital elevation model (1;10000) meet the basic mapping requirements.

Spider Truck: Revolutionizing Off-Road Mobility and Versatility

图片
  Introduction: Spider Truck, also known as a Spider Vehicle or Spider Car, is a remarkable innovation in off-road transportation. This cutting-edge vehicle combines the capabilities of a truck and a spider-like mechanism, providing unmatched mobility and versatility in rugged terrains. In this article, we explore the features, applications, and advantages of the Spider Truck. Design and Features: The Spider Truck derives its name from its unique design, inspired by the agility and adaptability of spiders. It features multiple legs or limbs attached to a central body, each equipped with wheels or tracks for independent movement. The legs are often hydraulically controlled, allowing  the Spider Truck  to navigate challenging landscapes with ease. Off-Road Mobility: The Spider Truck's primary advantage lies in its exceptional off-road mobility. The independent movement of its legs enables it to traverse diverse terrains, including steep slopes, rocky surfaces, muddy grounds, and dens

Elbow in the pipeline system , elbow is to change the direction of the pipe fittings. According to the angle, there are 45 ° and 90 ° 180 ° three most commonly used, in addition, according to engineering needs also include 60 ° and other non-normal angle elbow. Elbow materials are cast iron, stainless steel, alloy steel, malleable iron, carbon steel, non-ferrous metals and plastics. Connected to the pipe in the following ways: direct welding (the most common way) flange connection, hot fusion connection, electrofusion connection, threaded connection and socket connection. According to the production process can be divided into: welding elbow, stamping elbow, pushing elbow, casting elbow, etc.. 1. Divided by material. Carbon steel: ASTM/ASME A234 WPB, WPC Alloy: ASTM/ASME A234 WP 1-WP 12-WP 11-WP 22-WP 5-WP 91-WP911, 15Mo3 15CrMoV, 35CrMoV Stainless steel: ASTM/ASME A403 WP 304–304L-304H-304LN-304N ASTM/ASME A403 WP 316–316L-316H-316LN-316N-316Ti ASTM/ASME A403 WP 321–321H ASTM/ASME A
