Re: Spatial modeler for atmospheric correction and indices

I think I made a mistake in that Pleiades model - you need to invert the Gain values (1/Gains) rather than multiplying by 0.01. Should be an easy change to the model.

Re: Spatial modeler for atmospheric correction and indices

Greetings Ian:


I made the correction suggested by you, the data I enter is the input, output image and the other data that are in the dialog window. In the following image is the change, I have run the model and it works.


The "Table Input Gains * 0.1" function shows the old values, this function must be deleted.

I am attached the model and the xml file.


I appreciate all your kind collaboration to know if it should be so.


Cordially,
George

Re: Spatial modeler for atmospheric correction and indices

Greetings Ian:


I make another correction applying the equation c1 = (1 / Gain) * 0.1, I enter the data manually, the viewing angle option I find three values that are highlighted in the attached file, they really are those ?, because the value of your model is very small, around 0.87.

 

The function "Table Entry Earnings * 0.1" was removed.

 

I really appreciate your valuable collaboration to be able to have this model working well and make it a great contribution to those of us who work with Hexagon's products.

 

Many thanks.

Hi neo,

 

I don't think you need to multiply by 0.1 - just invert the gains.

 

For Sensor Zenith Angle I've been using "Geometric_Data > Use_Area > Located_Geometric_Values[0] > Acquisition_Angles > VIEWING_ANGLE"

 

Like this:  <VIEWING_ANGLE unit="deg">14.31497227629177</VIEWING_ANGLE>

 

Cheers
