Subject: [mget-help] scaling equation and cell size

Dear Jason and MGET users:

I am importing into ArcGIS monthly average data of chlorophyll
(Seawifs mapped monthly 9km resolution). Here is the header of one of
the files:


Variable Name = l3m_data
         Index = 0
         Type= 32-bit floating point
         Ref. = 2
         Rank = 2
         Number of attributes = 5
         Dim0: Name=fakeDim0
                 Size = 2160
                 Scale Type = number-type not set
                 Number of attributes = 0
         Dim1: Name=fakeDim1
                 Size = 4320
                 Scale Type = number-type not set
                 Number of attributes = 0
         Attr0: Name = Fill
                 Type = 32-bit floating point
                 Count= 1
                 Value = -32767.000000
         Attr1: Name = Scaling
                 Type = 8-bit signed char
                 Count= 7
                 Value = linear\000
         Attr2: Name = Scaling Equation
                 Type = 8-bit signed char
                 Count= 47
                 Value = (Slope*l3m_data) + Intercept = Parameter
                         value\000
         Attr3: Name = Slope
                 Type = 32-bit floating point
                 Count= 1
                 Value = 1.000000
         Attr4: Name = Intercept
                 Type = 32-bit floating point
                 Count= 1
                 Value = 0.000000

I am using a cell size of 8.33333333333333E-02 and nothing for the
scaling equation since the slope is equal one and the intercept is 0.
My results range from -32767 to 81.79. What I am doing wrong?

Thanks!
