【摘要】 针对地形图制图数据生产严重滞后于基础地理信息数据库建设的局面,设计了一套基于数据库的中小比例尺地形图制图系统,高效地从基础地理数据库成果衍生出符合国家标准的地形图制图数据。利用此软件系统可在现有测绘行业模式下快速获得现势性良好的纸质地形图。更多还原

【Abstract】 Cartographic data production is seriously lagging behind the construction of fundamental geographic information database. A cartographic software system of small and medium scale topographic data production based on the geographic database was designed,and executed the national topographic map standard. The up-to-date paper map can be quickly produced using this software system.更多还原
