The invention provides a geospatial data processing method, a device and a system. The method comprises the steps of connecting a client with a visual modeling service of a server under the conditionthat the client receives a starting instruction; establishing a model in response to a dragging instruction for any operator in the plurality of operators and in response to a connection instruction for the dragged operator; responding to a configuration instruction for the cluster information of the model, and configuring the cluster information of the model; generating a model file of the modelin response to an operation instruction for the model, and analyzing the model file by the server under the condition that the server receives the model file sent by the client to obtain operators included in the model indicated by the model file, an input-output relationship between the operators and cluster information; and controlling a distributed cluster indicated by an address in the clusterinformation, and executing a calculation task of each operator included in the model. The client provides a mode of establishing a model by dragging and connecting an operator, and codes do not needto be written manually, so that the production efficiency of geospatial data mining is improved.
