Abstract
A data collection method for a geographic database that represents geographic features in a region, and a system and program for performing the method. The data collection method includes obtaining a first copy of data from the geographic database without locking the data in the geographic database and performing an updating process using the first copy. A second copy of data from the geographic database is obtained. A determination is made whether application of the updating process to the second copy of data conflicts with any changes made to the geographic database since the first copy of data was obtained. If application of the updating process does not conflict with any changes made to the geographic database, the updating process is applied to the second copy of data from the geographic database. Then, the updated second copy of data is restored back in the geographic database.
