     - **Objectives:**
       * To present a new vector-based CA model that overcomes the problem of cell-size sensitive by allowing an irregular space tesselation where the neighborhood definition and the transition rules are connected to the real properties of each geographic object within the study area, and that allows geometric transformations of the geometric objects as a result of the transition functions.
-      * To tes the vector-based geographic cellular automata (VecGCA) model with real data and compare the results with those obtained using a classical raster-based CA model under the same conditions.

+    - **The proposed VecGCA model:**
+      * **Conceptual Model** -> Three components that correspond to modification to the classical CA model:
+        - //Space Definition// -> Space is composed of a collection of georeferenced geographic objects of irregular shape that represents the real-world entities. Each poligon is in a specific state and can define its propper transition function and neighborhood. Each geographic object is connected to others through adjacent sides and together they compose the whole space of a study area.
+        - //Neighborhood Definition// -> The neighborhood defines which objects determine the change of shape of a central geographic object. Usually, in geographic applications, a geographic entity is influenced by adjacent or nonadjacent entities separated by a distance //d//. In VecGCA model, the neighborhood is defined as an external buffer (region of influence) around each geographic object, and all the objects (adjacent or not) that are partially or totally within the region of influence defined by //d// are the neighbors of the central object. The size of the buffer that delineates the region of influence is expressed in lenght units and is selected by the user.
