In this study, a novel method was proposed for automated extraction of BUA at the global scale, by fusing a series of building features.
ZY-3 satellite is the first high-precision Stereo-mapping satellite for civilian purposes in China, which was launched in 9 Jun 2012. Ziyuan 1-02C was the third satellite in the CBERS-2 series, but was developed as a Chinese only project with no Brazilian participation. The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative
With multiple high-resolution satellite constellations now available (e.g., ZiYuan-3 (ZY3), SPOT-5/6/7, Cartosat-1/2, and WorldView-2/3), identifying the global BUA explicitly from the complex landscapes becomes possible.
A total group of 124 features and 24 landslides were used as inputs to determine the landslide boundaries and evaluate the landslide classification accuracy.
CEODE Director-General GUO Huadong extended warm congratulations to the related staff and technicians. DOAJ is an online directory that indexes and provides access to … The second satellite is managed by the Satellite Surveying and Mapping Application Center (SASMAC). The ZY3 stereo mapping satellite constellation is composed of two satellites, i.e., ZY3-01 and ZY3-02, which were launched on 9th January 2012, and 30 May 2016, respectively (Tang et al., 2013, Tang et al., 2015). ZY-3 stereo pairs are applied to produce 1:50,000-scale maps, and 2D imagery applies to update 1:25,000-scale maps.
Moreover, two multi-angular built-up indices (MABIs), i.e., Ratio Multi-angular Built-up Index (RMABI) and Normalized Difference Multi-angular Built-up Index (NDMABI), were proposed to represent the vertical properties of buildings based on multi-view images, which can further complement the planar features.
The satellite is China's first operational civilian remote-sensing satellite, specifically designed for the Chinese Ministry of Land and Resources (MLR). The results show that the fusion of MBI and Harris corner can achieve satisfactory accuracy, i.e., 91.12%, 88.85%, 82.82% and 0.85, for the average overall accuracy (OA), user's accuracy (UA), producer's accuracy (PA), and F1-score, respectively, for all the test cities.
A novel method for automatic built-up area extraction with ZiYuan-3 multi-view images. Miyun Stationâs successful completion of a link test between the satellite and ground, receiving high bitrate spot beam signals, verified the technical status of the ground receiving system and laid a solid foundation for receiving the ZY3 satelliteâs real-time image data. In this study, a novel method was proposed for automated extraction of BUA at the global scale, by fusing a series of building features.
It carries three high-resolution panchromatic cameras and an infrared multispectral scanner (IRMSS).
Since its launch on January 9, 2012, it has been in operation for one and a half years. ZY-3 takes 5 days to revisit the same site.

In our study, an object-oriented landslide mapping (OOLM) framework was proposed for reliable and accurate LM from ‘ZY-3’ high spatial resolution (HSR) satellite images. On 11 January, CEODEâs Miyun Ground Station successfully received the first track of satellite imaging data from the ZY3 satellite and implemented real-time recording and large capacity optical data transmission.

A dual-polarized, high-bitrate technology was applied for the first time in a remote sensing satellite ground system to receive the satellite data, which indicated that China's land observation satellite data reception technology had entered a new level of development.
Average overall accuracy and F1-score of all the test areas were higher than 90% and 0.85, respectively.

Automatic extraction of built-up area from ZY3 multi-view satellite imagery: Analysis of 45 global cities. The ZY3 satellite fills the gaps in China's civilian mapping satellites and serves as a milestone in enhancing China’s independent access to high-resolution geospatial information and resolving the strategic shortage of fundamental geographic information resources. Multi-angular built-up indices (MABIs) were proposed to represent the vertical characteristics of buildings.

Finally, the landslide inventory maps were obtained. It has served steadily on orbit for more than three years. Based on its efficiency and accuracy, the proposed approach can be employed for rapid response to natural hazards in the Three Gorges area. Accurate delineation of global built-up area (BUA) is fundamental to a better understanding of human development and the impacts on global environmental change. Landslide mapping (LM) has recently become an important research topic in remote sensing and geohazards. Copyright © 2019 SpaceWill Info.
