Distance computation takes a long time #145

Closed jtpesone closed 1 month ago

jtpesone commented 2 months ago

Description Distance computation (in wizard and processing algorithms) takes much longer than in ArcGIS (3 sec vs 1 min)

Repro steps Follow the steps for issue #144 for computing the distance.

Expected behavior Computation time should be closer to ArcGIS's

Desktop:

It would be better to benchmark the performance ofDistance computation using the processing algorithm directly. Could you run Distance computation using Structures line data from the IOCG test dataset with a base raster of roughly the same extent, such as the EM ratio data from the IOCG test dataset, and benchmark the performance EIS vs ArcGIS version?

Closing this as optimizing the algorithm is done in EIS Toolkit and issue for that exists.
