[mapserver-users] how to add a time stamp on raster data

[Lime, Steve D (DNR)]

Probably, you'd do it through an annotation layer. What version are you using? What interface (CGI, WMS, WCS)? Basically the idea would be to funnel the time parameter into a TEXT expression in the annotation layer. Layer would look like (assuming a variable called 'time' is passed) this I think:

LAYER
  NAME 'timestamp'
  TYPE ANNOTATION
  STATUS DEFAULT
  TRANSFORM LL # lower-left corner of the
  FEATURE
    POINTS 10 10 END
  END
  VALIDATION
    'time' 'some expression that matches time values'
  END
  CLASS
    LABEL
      ...
    END
    TEXT '%time%'
  END
END

This would plop the passed time in the lower left corner of the output, or at least I think it should.

Hi all,

We have a set of time-series data. Is it popossible to add a time stamp, i.e. the value of time parameter in the request, on raster data? Thanks.
