The invention relates to the technical field of risk monitoring, in particular to a
brucellosis risk monitoring and early warning method based on
remote sensing and GIS (
Geographic Information System), which comprises the following steps of: acquiring multi-stage
remote sensing images to construct an ecological grid set, hanging cases, positioning and generating a
disease source boundary map layer, identifying a high
vegetation and temperature intersection area to form a risk structure, and carrying out early warning on the risk structure. And extracting the display area and superposing the GIS map to output early warning information. According to the method, the multi-stage
remote sensing image covering the key epidemic area is obtained, region segmentation and
geocoding registration are executed, by means of
coupling detection of the normalized
vegetation index and the
land surface temperature, the spatial intersection region with the
pathogen propagation suitable ecological condition can be identified, the
risk index is calculated according to the graph
block structure distribution, and the
risk level label is given; according to the method, accurate positioning and hierarchical evaluation of a high-risk
ecological environment and historical case space overlapping region are realized, the space prediction precision and the intuition of risk prompt are improved, and the capability of responding to the
brucellosis potential
outbreak trend in advance is effectively enhanced.
