| - | The **Source** port of [[:Calc Cost Map]] functor will receive the Map ''railroad.tif'' and the **Friction** port will receive the map output by the third Calculate Map //[[:Calculate Map]]//. Turn on **Diagonals Cost More**. This will penalize the movement across diagonal cells. Set **Maximum Number of Passes** to “2”.

| - | Save the model to a new file ''my_pathway.egoml'', and run it (the model does not run on Dinamica 4, because it is been used two 'different' projections to calculate cost map). This is going to take only a little while. Dinamica EGO has superior performance in relation to most commercial GIS packages; you may want to try this model on other software just for performance comparison. Open on the Map viewer ''railway.tif'', using "PseudoColor" as **Current Color Palette**. What do you see?\\ | + | Save the model to a new file ''my_pathway.egoml'', and run it.
