Mimic Geographic Information System

Abstract

With the development of the Internet, the geographic information system gets a chance to develop rapidly. Aiming at the security problems of existing geographic information systems, a Mimic Geographic Information System, i.e. M-GIS, based on mimic defense is proposed to improve the security of geographic information systems. The system consists of heterogeneous redundancy geographic information execution bodies pool, request distributor, scheduler and arbiter. Firstly, the scheduler dynamically selects the geographic information execution bodies set for processing, and then makes a mimic decision on the processing results. The experimental results show that the mimic system is more security than traditional system.

An Improved TransMVSNet Algorithm for Three-Dimensional Reconstruction in the Unmanned Aerial Vehicle Remote Sensing Domain

“…Moreover, the application of 3D reconstruction technology in the field of UAV remote sensing [24] has been expanding, providing richer information and data for topographic surveying [25], urban planning [26], environmental monitoring [27], and other fields. By carrying photographic equipment for aerial photography using unmanned aircraft and processing and analyzing aerial images with 3D reconstruction algorithms, high-precision and high-resolution 3D maps [28] and models can be constructed, providing data support for other geographic information systems [29] and geoscientific research [30]. Compared with traditional multi-view stereo (MVS) vision datasets, the scenes in UAV remote sensing images are more complex, the image resolution is larger, and the impact of weather and other factors may lead to lower texture clarity in the image.…”
