Multipoint routing geoprocess

A new geoprocess has been added to perform multipoint routing, meaning that Pathfinder will automatically find the most optimal combination of paths to join a number of unsorted locations. Both existing connections and excluded connections can be specified.

This geoprocess can be used, for instance, in grid expansion studies and connecting multiple wind turbines with feeder lines.



As with other geoprocesses, this one may not be activated in your company automatically. Check with Gilytics if you want to use it.

Pipeline optimization geoprocess

Gilytics has developed a specific geoprocess for pipeline optimization.


This geoprocess can be used to optimize the pipeline infrastructure with a cost perspective and display the resulting pump and pressure reduction stations in Pathfinder.


This geoprocess requires expert knowledge. For more information about using it, check with Gilytics.

Specify dimensions in optimal site geoprocess

The optimal siting geoprocess, used to find optimal locations for substations, power plants, etc., now allows the specification of the width and height of a precise rectangular area:



Don’t forget to activate the checkbox to apply these parameters.

Forbidden value in Explore algorithm

Unlike other routing algorithms, the Explore algorithm doesn’t apply the forbidden (FB value) constraint strictly. Because of the way the algorithm works, assigning to FB areas an “infinite” resistance (as the other algorithms do), would create problems in the optimization.

For this reason, the Explore algorithm internally assigns a high (but finite) resistance value to the FB areas. As a result, solutions calculated using Explore might still cross these areas, and this may be fine (for instance, crossing a river when it’s not too wide).

Now, in the Explore configuration within each scenario, users have control on which resistance value is used by Explore in FB areas and, therefore, they can control how strictly these areas are avoided. The larger this resistance value is compared to the overall resistance map, the more strict the FB constraint will be.
