嵌入式GIS空间数据的内存管理研究

在嵌入式GIS中,嵌入式设备具有存储空间小、内存小、存取速度慢等缺点。为了适应嵌入式GIS的硬件环境,节省系统运行所需要的硬件资源,需要对空间数据的内存使用情况进行管理。提出了利用空间表和堆内存池的方法对系统的内存进行管理,使用这两种方法可以有效地组织和管理内存空间,优化系统结构,对嵌入式GIS的开发具有参考意义。

Management of the Embedded GIS's Memory Usage on Spatial Data

In the Embedded GIS,the equipments have some characteristics such as the storage space is small,the memory is small and the access speed is slowly and etc.For adapting the hardware environment of embedded GIS,saving the hardware resources which the system needs,we should manage the memory usage of the spatial data.This text put forward to make use of the method of space list and heap memory pond to manage the memory usage of system,using these two kinds of methods can effectively organize and manage the memory space,and that will have reference meaning to the development of embedded GIS.
