                                                       SIAPRenderer

A renderer for a the Simple Image Access Protocol.

These have errors in the content of an info element, and they support metadata queries.

For registration, services using this renderer must set the following metadata items:

• sia.type -- one of Cutout, Mosaic, Atlas, Pointed, see SIAP spec

You should set the following metadata items:

• testQuery.pos.ra, testQuery.pos.dec -- RA and Dec for a query that

  yields at least one image

• testQuery.size.ra, testQuery.size.dec -- RoI extent for a query that

  yields at least one image.

You can set the following metadata items (there are defaults on them that basically communicate there are no reasonable limits on them):

• sia.maxQueryRegionSize.(long|lat)
• sia.maxImageExtent.(long|lat)
• sia.maxFileSize
• sia.maxRecord (default dalHardLimit global meta)
