A method for classifying a spatial data carried out by a data computing environment. The method includes: receiving a spatial data from a data source; generating a first feature from the spatial data; dividing the first feature into a first sub-feature and a second sub-feature; analysing the first sub-feature to derive a first sub-feature data; analysing the second sub-feature to derive a second sub-feature data; using the first sub-feature data and the second sub-feature data as a first input data for analysing the first feature; and analysing at least one of the first sub-feature data, the second sub-feature data, and the first feature to classify the spatial data into a plurality of object classes.
