摘要： Provided is an apparatus and method for downsizing surface elevation data. The method includes receiving surface elevation data consisting of a plurality of cells, sequentially searching all the cells in a predetermined direction, comparing data of a cell having a predetermined reference elevation value or more with data of nearby cells, setting the cell as a boundary region when there is a nearby cell having different elevation data than the cell, grouping cells having the same data centered on the cell set as the boundary region, and performing triangulation on the basis of the grouping results. Since pieces of the same elevation data among pieces of high-resolution surface elevation data used in an outdoor environment are grouped as one, it is possible to carry out efficient analysis and improve analysis speed.
