Embodiment 1

[0094] A in this example 1 Group and B 1 The set of data is randomly distributed over 100m 2 Two sets of data within the range, the coordinate system is CGCS2000, each point is given a random number from 0 to 1, and the data volume of the two sets of data is N A1 =9,N B1 =6( figure 2 ). Set the detection methods of the two groups of data to be different, and if A 1 Group data detection method promulgated later than B 1 group data.

Abstract

The invention relates to a multi-source soil environment data detection and space fusion processing method. The method comprises the following steps: acquiring multi-source soil environment data by using a field sensor and a chemical reagent method; carrying out grouping according to attribute categories of the data; carrying out fusion processing on any two groups of data of the same attribute category; on the basis of judging whether the two groups of data detection methods are the same or not, adjusting the data according to a characteristic value difference value of the data; judging whether the positions of the two groups of adjusted data are overlapped in space or not, and comparing and adjusting the data again according to a data confidence interval or an interpolation result; combining the final adjusted data to generate fused data; and visually performing displaying by adopting an image processing method. According to the method, the data fusion problem that multi-source survey detection results and spatial point locations are not completely overlapped can be solved, a data basis is provided for space-time dual-scale mining of data, and long-time discrete multi-source soilenvironment data can be spatially fused and displayed.

Description

technical field [0001] The invention relates to a spatial fusion method of multi-source data, in particular to a detection and spatial fusion processing method of multi-source soil environment data. Background technique [0002] In 2015, the State Council issued the "Action Outline for Promoting the Development of Big Data", which elevated the development of big data to a national strategy, and data power is the focus of development in the next ten years. In the environmental field, in addition to relying on the high-frequency reception of sensors and real-time data generated by the Internet, big data is also an important source of data at different scales, fixed-point monitoring, and long-term surveys. [0003] Regarding the data nature of soil environmental data, compared with water, air and other media, soil environmental data has the characteristics of slow update. It is difficult to directly integrate different batches of survey data, which leads to poor data contrast,...
