Based on a set of search parameters the script will create a query on www.scihub.copernicus.eu and return the results either as shapefile, sqlite, or write to a PostGreSQL database.

Functions:

gdfInv2Pg:

writes the search result into a PostGreSQL/PostGIS Database

gdfInv2Sqlite: (tba)

writes the search result into a SqLite/SpatiaLite Database
