智能地质体综合技术在地质图缩编中的应用

地质图缩编过程中存在地质体合并效率低、处理环节繁杂、成果质量难以保证等问题。提出了一套新的地质体智能化综合方法，依托地图综合方法、人工智能算法、地质专家知识等，采用同属性合并、空间聚合、自定义融合、地质体消除、地质体夸大等方法进行智能化处理。MapGIS版智绘地质软件中实现了地质体智能综合处理模块，采用自动或人机交互式并行工作模式，通过"一键式"操作可快速完成地质体综合任务。经实际数据测试，验证了地质图缩编中地质体智能综合方法的正确性，可节省80%以上的工作量，极大提高了编图人员的工作效率，对未来开启地质图件智能化编制具有重要意义。

An intelligent generalization method of geological body for MapGIS geological map downsizing

Some complex problems have to be faced during medium-small scale map making from large scale geological map, such as low efficiency to merge massive geological polygons, complicated processing procedures, and being difficult in assuring data quality.This paper proposes a novel intelligent generalization method for geological body based on cartographic and artificial intelligence.Dissolving, spatial aggregation, customized fusion, elimination and exaggeration are employed to perform intelligent processing integrating map generalization and intelligent algorithms.iMapower(MapGIS version)implements the above generalization methods in corresponding modules, which can run automatically or in the form of human-computer interaction.It is very easy to complete most of complete geological body mapping tasks just clicking one time.Using real data to verify the proposed method is effective and can be corrected during mapping from large-scale map to small-scale map, and it can save at least 85 percent of geologic body generalization workload.It can greatly improve the work efficiency and assure the data quality.Furthermore, this way can play an important role in pursuing intelligent compilation of geological map.
