According to the grid, the lowest contour line selected on the topographic map, the contour line which can control the basic shape of the landform, and the positions of the top, saddle, foot of the mountain, inclined transformation point and river are drawn on the sand table

Mark the height of the top of the mountain, saddle, foot of the mountain, inclined transformation point and bend of the river.

Within the range of the lowest contour line, according to the marked height and contour line, first pile up the outline shape of the top, saddle, back of the mountain as the backbone, and then trim other parts. If the sand table is large, it can be piled up in pieces, first pile up the difficult parts, and then pile up the convenient parts. When stacking, it should be compared with the topographic map at any time to correctly show the ups and downs of the landform, and the sand should be compacted at any time, If there are large rivers and lakes, they should be excavated at the same time when trimming the landform. After the accumulation, they should be checked and trimmed comprehensively.

The features on the sand table, such as houses, railways, bridges, trees and independent features, are usually represented by similar models. The width of roads and country roads varies, and different colors are used to represent them. Rivers are represented by blue. Trees are represented by twigs or green. The size of the features should be adapted to the horizontal scale, and the relationship position should be correct. The features should be set according to the sequence of water system, residential area, road, forest and independent features. Finally, place name, river name, mountain name and elevation mark should be inserted on the corresponding position.
