| description | This paper is focused on applying digital map generalization into the updating of geo-spatial database from large scale in the
collaborative updating environment for SDI, an updating production line system for national topographical database at 1:50k of
China is introduced. Based on the requirements analysis and review, we analyze the key factors for implementing updating
geospatial data from large scale including technical and non-technical factors, followed by the general strategy of digital map
generalization in practical production environment. In fact the most important factor is recognized that it is very difficult to establish
generalization rules for production systems. We emphasized on this factor in our work and established a set of rules or constrains for
scale topographical database updating 1:50k scaled data from 1:10k scaled data in a full digital environment mainly based on map
specifications. Finally, the production line system structure is designed and the practical implementation is given. |
