Depicted hardware (field-map technology) is used mainly for forest inventories, monitoring and mapping.
A full example of a WSGI network server is outside the scope of this article. Below is a sketch of how one would call a WSGI application and retrieve its HTTP status line, response headers, and response body, as Python objects. [10] Details of how to construct the environ dict have been omitted.
