Purpose: To fine map the presence of plaques to optimize the merger.
Merge Conditions: spatially adjacent, the same properties
Uses: cartographic generalization, data processing, auto-depth study sample extraction.
Tool Name: DissolveAndEliminateMinValuesByAttribute
Precautions:
1 Try not to choose the system field. Because of the need to generate temporary data in memory, the system fields may be disposed of, the user can not control.
2. The pattern can be gradually enlarged to be merged condition. For example, an area of small to large, divided two or three times an iterative process.
3. This tool can be customized, optimized directions: not only processes the same properties, but also (to sort distance matrix) according merge with adjacent polygons. It may also incorporate non-adjacent polygons. And set priorities.
