Digital terrain models are quickly and easily created with card_1. Numerous construction and evaluation methods assist you when checking your volumetric calculations. Cross-sections are easily and efficiently designed with the card_1 cross-section designer, based on either Elling or bounding line method calculations.

The results of volumetric calculations are provided as printouts in compliance with REB as well as complete check-data records. Standard interfaces to import and export data guarantee easy data exchange.
