The present application belongs to the technical field of hydrological
data processing, and particularly relates to a
water level data collating method and
system and a computer readable storage medium, which comprises the following steps: S1, collecting original
water level data of different sources, and performing data preprocessing on the original
water level data to obtain standard water
level data; S2, judging whether there is an anomaly based on the standard water
level data; if yes, proceeding to step S3; if no, proceeding to step S4; S3, performing interpolation repair, and then proceeding to step S4; S4, performing
data reduction through
dynamic feature point screening threshold control and a feature point
screening algorithm, retaining key feature points in the water
level data, and obtaining reduced water level data; S5, performing line setting and flow pushing based on the reduced water level data, and obtaining collating results; wherein the collating results comprise water level collating data and flow collating data. Through the whole-process
processing of data preprocessing, anomaly identification, interpolation repair,
data reduction and line setting and flow pushing, efficient and accurate
collation of water level data is realized.
