Editing a Mixture Model
This page presents how to Create and Modify a Mixture Model.
Mixture Model
Creating a Mixture Model:
- At the window "Create Mixture Model", type on the Name: field, a name for the model, replacing the text "modelo" that is already there. The data will be saved in a file with an extension *.mix;
- We will have two lists, the first bands are chosen on the model, these bands are stored in "SpectralBands" which is in the /etc directory, under which is installed SPRING. This file contains the names of bands,
the code of the band and spectral range (in microns) to which it belongs, and the second are the images that will be implemented in the model. See that there is a relationship between the first band selected with the first image, or choose the first band and it relates to the first image that will be applied in the model. The relationship is shown in the list of bands in the model. To remove the relationship, and just click over the image selected again.
- now, inform the model components: click on Create... and you will see the windows "Create/Edit
Mixture Components" and "Graphic". You should have in mind which components will be defined (for instance, water, shadow, forest etc.) and the acquisition of reflectance values (from the image,typing on the keyboard or Library);
- after editing the mixture components, click on Save
to store the crated model. A file named <model_name>.mix will be created containing all information provided above. Now, you are ready to apply the model.
