Description
Technical Field
The embodiment of the invention relates to the technical field of information processing, in particular to a palm area identification method and a palm area identification product based on multi-source information analysis.
Background
Brown generally refers to a site with known or potential contamination due to human activities, and its reuse needs to be based on site risk assessment and remediation based on the intended use. Brown land and its regeneration are global issues that require global serious treatment due to its enormous number and widespread distribution throughout the world.
In the related art, scholars at home and abroad have conducted several studies on the brown land recognition method, and the conventional brown land recognition technology can be divided into 3 main types. The method is high in efficiency (automatic identification), but the identification result is greatly influenced by image data, open source data cannot be obtained, and the method has no universality and popularization value. And secondly, a brown zone artificial identification method based on non-open source information is low in efficiency, and key information has no public obtaining way and has no universality and popularization value. And thirdly, a brown land manual identification method based on open source information, and although the identification technical process can be copied and has a certain popularization value, the identified brown land type is limited. In addition, the above 3-type recognition method has a single approach to determining the site abandonment state, and is mostly investigated in the field, which increases the investment of time and labor cost.
In addition, because the types of the brown lands are more and the remote sensing image characteristics with uniform identification degree are not available, the remote sensing technology is used for automatically identifying a large number of types of brown lands in a large range in the field of landscape and garden discipline at present, and the method is difficult to realize. Compared with the identification of urban land cover by using high-resolution remote sensing images, the research of carrying out fine identification on urban land use distribution by using remote sensing supervision and sub-supervision classification technology is less.
Different from the land cover, the land utilization refers to the use mode of people in the aspect of social and economic functions, and is difficult to directly extract from the remote sensing image data. Regarding the brown land, because the types are various and have high heterogeneity, the method does not have uniform spectral features, geometric features and textural features with identification degree, and when the remote sensing images with the resolution of 30m in the Landsat series are used for identifying the brown land, the method is easily confused with bare land, sand, roads and other construction lands, and the effect is not good. Therefore, the method for identifying the vegetation, the water body, the urban buildings, the roads and other ground features by utilizing supervised and unsupervised classification based on the Landsat series free remote sensing images is not suitable for brown land identification.
Therefore, a new brown land identification method is needed.
