Knowledge discovery from the geographical dataset is critical for understanding weather behavior and global warming impact. However Geographical data is complex and growing exponentially. A major effort goes into the accusation of geographical (raw) data, which contains possible errors, is un-validated, unformatted, un-coded with missing and wrong values. Resultantly Geographical database development costs up to 70% [1] (or more) of time and effort. In this paper, we present novel algorithms to convert raw geographical data into error-free, clean, validated and formatted Databases. Further resultant geographical database is visualized for further understanding of dataset, which shall works as impetus for data engineers and scientists [3][4][5][10-15].
