Spatio-temporal data model on updating of forest resource spatial data
Geographic Information System (GIS) technology can achieve the spatial data and attribute data storage, management, and data updates, but lack of time data. It is often difficult to achieve historical inquiries. Taking the forest subcompartments as an example , this paper analyzed the spatial shape changes of data updating outside the natural growth of trees, and described temporal and spatial information of forest resources subcompartment data updated based on graph theory, At last it built the spatio-temporal updated data model to historically inquire and analyze information.
