Term Details

The Coverage Processor for points performs three different activities:

• WCS Query Parser. The syntax is checked and parsed into structured object.
• SQL Query Compiler.
  • Fields:
    • Select required fields
    • join in location table
    • join in tables for fields
  • Filters:
    • Bounding Box: Add SQL filter by location lat and lon.
    • Time: Add SQL filter by datetime.
    • location: if requested, add SQL filter by location
• Formatter. The table data is returned in desired format. Currently the only supported is CSV, Comma Separated Values.

SQL processors can be either configured to supported DB schema types, or custom written for esoteric databases.

By writing a custom processor, anything can be used as a data source.
