DigiRoad
GDF –basedDelivery in two forms
1. With linear referencing (dynamic segmentation)2. With directly attached attributes

PerformanceWhen geometric matching included
1.5 ms / Feature with a small dataset (0.1 MB) 3.1 ms / Feature with a big dataset (1.5 MB)
Without geometric operationsNearly constant 1.0 ms / Feature
