The D2 PSDK is an upgraded version of the S2 PSDK, with the capability of 1:500 cadastral free image control. Compared with S2 PSDK, it has higher compatibility, not only can be adapted to M200/M300 series drones but also can be mounted on other mainstream rotor drones. In terms of software, we have configured aerial photo removal software for the D2 PSDK camera, which can effectively eliminate invalid and redundant aerial photos and improve the efficiency of the office. D2 PSDK is also a product that you can buy at a low price, with very high cost performance. It is a good tool to ensure efficiency and effect for the "integration of premises and land" project.
