Embodiment Construction

[0039] In order to express the present invention more clearly, the present invention is further described.

[0040] The following is an example of the fusion of wastewater production data in a river basin in Hefei City, combined with the attached drawings to further explain, refer to figure 1 , the fusion method includes the following steps:

[0041] Step 1. Divide all the acquired environmental data into several groups according to different temporal and spatial resolutions

[0042] The data related to water quantity in the basin can be divided into water supply data of waterworks, with the unit of minute as the scale unit; data of water consumption of each user, with the unit of month as the scale unit.

[0043] Step 2. Organize the environmental data in each group

[0044] The water supply data of the waterworks is in minutes. The data is complete and does not need to be sorted. It only needs to be added and converted into data in days in step 3.

[0045] The collation p...

Abstract

The invention discloses a multi-scale environmental data fusion method. The multi-scale environmental data fusion method comprises the following steps of: firstly, dividing all acquired environmentaldata into several groups according to different spatial and temporal resolutions with each group of data of the same scale range and the same scale unit; secondly, organizing the environmental data within each group, which including environmental data unification, missing environmental data interpolation and correlation of different types of environmental data; thirdly, transforming scale ranges of different sets of data into required scale ranges, and transforming scale units of different sets of data into required scale units; fourthly, conducting fusions of all groups of data and constructing the environmental data with the same temporal and spatial resolution. The multi-scale environmental data fusion method has the advantages that the environmental data can be divided according to different spatial and temporal resolutions, the environmental data of different spatial and temporal resolutions can be respectively organized, and data fusion is finally conducted; scale ranges and scale units therein can be chosen according to actual needs; the the multi-scale environmental data fusion method is wildly applicable.

Description

technical field [0001] The invention relates to the field of environmental data processing, in particular to a multi-scale environmental data fusion method. Background technique [0002] There are three dimensions in environmental research, namely logical dimension, time dimension and spatial dimension. Although there is continuity in the three dimensions of environmental elements, in specific environmental research, it is usually examined from a specific scale in the three dimensions of specific environmental elements. Dimensional rules. A large amount of environmental data of different scales will be involved in this process. How to integrate these environmental data according to certain rules is an important guarantee to ensure the reliability of environmental research results. [0003] The existing multi-scale fusion patents in the field of environmental research are mostly aimed at the fusion of later images, but lack the analysis and processing of the basic environmen...
