Sensor web enhancement（ SWE） of open geospatial consortium defines heterogeneous sensor uniform description standard

but the process of underlying heterogeneous data access to SWE is not clearly defined

which will lead to manual operation for accessing to each type of heterogeneous data. To solve the problem

a sensor information model called HSIM is designed. HSIM not only describes sensor properties and observation ability

but also summarize sensor data structure and data transmission protocol; a method for adaptive accessing of heterogeneous sensor data is proposed

and the method achieves automatic parsing through dynamically generate adapter and access SWE automatically. Access meteorological heterogeneous data adapter access system proves that the proposed method can achieve automatic parsing and accessing of heterogeneous sensing data with less manual intervention

and the method provides an effective way for dynamic integration of heterogeneous data.
