Hi,

I need to calculate the least-cost path from a destination point to a source. In ArcGIS I use COST PATH based on the least-cost distance raster (by Cost Distance tool in ArcGIS).

is there a way to do something similar in FME? is the Network cost calculator transformer appropiate?

Best regards,

Felipe Verdú

Look at the NetworkCostCalculator but perhaps also the ShortestPathFinder.

@david_r I need a cost surface as input and I don't think the NetworkCostCalculator can use it. how can I set the cost on that transformer? or other transformer? :)

I've never used those ArcGIS tools, so I've no idea what a cost surface is.

 

Generally speaking the FME transformers don't really translate 1:1 to some ArcGIS counterpart. The ArcGIS toolboxes are fairly solution-based, whereas the FME transformers are more task-based and also much more fine-grained. This means that you'll often need several/many FME transformers to get the same functionality as an ArcGIS toolbox, and I suspect that would be the case here.

 

Anyone solved this? Just to explain further, this would, for example add a "cost" to the distance between a point and its closest neighbour based on one or more surfaces (for example elevation). And it may or may not be via a vector network.

Hi @braggken​ I didn't continue to solve it via FME but as you said this is quite relevant.

Do you have any ideas?
