地形图多种多样,对于县地形图如何管理呢?我们在实践中摸索出“四个一”的管理方法,即采取一单(发图单)、一卡(地形图存取数统计卡)、一簿(卖出地形图登记簿)、一分开(地形图单幅分开存放)的办法进行管理。我们感到,这样做条理清楚,存取方便,容易统计,省时省事。现将具体方法介绍如下: 发图单即发图单位(如省测绘局)开出的地形图清单。它详细地记载了每次调拨或购买地形图的情况,我们将其按时间顺序归在一起,以代替“领回地形图登记簿”,这样,既节省重新登记的时间,又便于保管、
Topographic maps varied, how to manage the topographic map for the county? In practice, we explored the “four one” management approach, that is, to take a single (send a single), a card (topographic access statistics card) , A book (sold topographic register), a separate (topographic map separately stored) approach to management. We feel that this is done in a clear and organized manner, easy to access, easy to count, and time-saving. The specific methods are introduced as follows: send a chart that is issued units (such as the Provincial Mapping Bureau) out of the topographic map. It records in detail the circumstances under which each topographic map is allocated or purchased and we put it together in chronological order in place of the “Topographic Register Retrieval Form” so as to save time for re-registration and to facilitate safekeeping,
