Technology used to generalization
process BDOT10k to BDOO
Technology:
• FME Desktop,
• FME Server,
• MRF2DCleaner.

Conclusions
One coherent model for BDOT10k, BDOO – DLM, and one for
DCM (all LoD’s) helps in data management.
BDOO quality and degree of automation of generalization
precess depends largely on the quality of the BDOT10k database.
 Errors in directional network of watercourses influence the
effect of generalization process.
 We have to change the DLM generalisation process BDOT10k to
BDOO to fully automatic.
 We plan to build fully automatic DCM generalisation processes
for LoD’s 10k, 25k, 50k, 100k, 250k, 500k, 1000k.
