d) using said binary decompressor;

2) at least one image accessor capable of using an optimized data access mechanism, the optimized data access mechanism using:

a) a hash index mechanism configured to locate data pieces using a hash function of coordinates of said data pieces; and

b) a cut mechanism configured to:

i) generate cut data pieces by cutting data pieces according to a requested area; and

ii) reassemble said cut data pieces to get a response data;

3) at least one map configuration mechanism capable of making dynamic request;

4) at least one data storage access mechanism capable of using binary indices for storage and retrieval of data;

5) at least one data source manager capable of managing at least one of said data storage access mechanism; and

6) at least one server-side spatial manager capable of processing said at least one dataset.
