Regular visits to park green space offer remarkable benefits for the physical and mental health of urban residents. Achieving a comprehensive understanding utilization across entire city is prerequisite improving overall rate spaces. Traditional social survey methods are limited by their sample size time-consuming nature, while based on geographic location big data gaining momentum. This study focuses Xuchang, medium-sized in China, systematically analyzes current state influencing factors...
Coastline extraction is a fundamental work for coastal resource management, environmental protection and sustainable development. Due to the free access long-term record, Landsat series images have potential be used coastline extraction. However, dynamic features of different types coastlines (e.g., rocky, sandy, artificial), caused by sea level fluctuation from tidal, storm reclamation, make it difficult accurately extracted with coarse spatial resolution, e.g., 30 m, images. To this...
Mapping land surface water bodies from satellite images is superior to conventional in situ measurements. With the mission of long-term and high-frequency quality monitoring, launch Ocean Land Colour Instrument (OLCI) onboard Sentinel-3A Sentinel-3B provides best possible approach for near real-time body mapping. Sentinel-3 OLCI contains 21 bands ranging visible near-infrared, but spatial resolution limited 300 m, which may include lots mixed pixels around boundaries. Sub-pixel mapping (SPM)...
Park green space is an important ecological factor of the urban built-up environment, and it plays increasingly role in improving human welfare quality life. Accessibility analysis park issue social equity environmental justice that has received widespread attention. The accessibility a city’s must be evaluated under correct scale resolution before can applied to planning. To measure impact different research scales on accessibility, Weidu District Xuchang City, Henan Province, China, was...
Landsat series images are the main data resources used for coastline monitoring. However, 30 m spatial resolution of multispectral (MS) image is always dominated by mixed pixels around coast areas. Given that latest Landsat-8 Operational Lands Imager (OLI) imagery has a 15 panchromatic (PAN) band, it instinctive to improve extracting accuracy directly using pansharpening approach. The sharpened MS image, however, may still not be sufficient in real applications, due meter-level...
Equitable and high-quality medical services are more urgent in underdeveloped cities for the higher population ageing demanding social justice. However, there is little attention paid to multi-level services, particularly regarding time indicators under latest policies cities. The improved efforts were hampered partly by single scenario of location optimization, ignoring integrated optimization both road infrastructure institution location. Toward healthy China 2030 rural revitalization...
According to the characteristics of road traffic accident data, designed a proper linear referencing system and dynamic segmentation data model. Then take Xu Chang as an example, introduce process building database in detail. This can well satisfy needs quring information summing up laws accidents analyzing reasons. Finally, summarize superiority model over traditional moel.
The veracity of land evaluation is tightly related to the reasonable weights factors. A new method proposed for determining factors by combining subjective and objective based on rough sets mining theory in this paper. Objective weight obtained theory. On basis experience knowledge practical applications, decision-makers can choose appropriate experiential factor adjust proportion between order get more effective weights.
According to the characteristics of bus system data, designed a proper linear referencing and dynamic segmentation data model. Then take as an example, introduce process building database in detail. This can satisfy needs public transportation information inquiry well. Finally, summarize superiority model over traditional moel, while also point out unavoidable defect.
