Motivations

Some of the design requirements of Environmental Management Systems:

  The complex relationships that happen in this environment,

  The underlying technology that is used,

  The organization of the work, and

  The requirements for the accomplishment of the tasks.

We need to have innovative quality information systems to guarantee the success of the everyday activities

Ontology  It is used in applications that need to

manage the information semantic.

= Ontology Paso 1. UML class diagram

Paso 2. Model-transformation +

 We have created an Ontology to model Environmental information linked to hierarchical ecological classification

Future work

•  To integrate this ontology with another one for the satellite images classification and extend it by using EML and GML.

•  To connect the SOLERES presentation logic with the data logic.
