Subject: | [mget-help] scaling equation and cell size |
Date: | Fri, 30 Jul 2010 17:23:55 -0400 |
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!
