Quickly prepared terrain sand table and preparation device thereof

Abstract

The invention provides a quickly prepared terrain sand table and a preparation device thereof. A plurality of columnar stacking units are cut and prepared, an axial section of each stacking unit is spliced to correspond with a horizontal cross-sectional shape of the terrain sand table, and the radial height of each stacking unit and the elevation data of each stacking unit in a corresponding areain the terrain sand table conform to the scale relationship of the terrain sand table. According to the invention, foam plastic instead of sand is used as a raw material for stacking, based on generalgeographic data information, the grid segmentation of the stacking area is performed, the elevation data of each cell is extracted, the raw material for stacking is cut into lengths in one-to-one correspondence with a local elevation, the stacking time of the sand table can be effectively shortened, the stacking accuracy of each point in the sand table is improved, the local topographical morphology is accurately presented, and a good basis is provided for a user to analyze and judge.

Description

technical field [0001] The invention relates to a terrain sand table. Background technique [0002] At present, sand table stacking is mostly manual work, using sand as the main raw material, which takes a long time, consumes a lot of manpower, is slow, and has low precision. There is a certain difference from the actual terrain, which objectively affects the accuracy of the user's judgment based on terrain analysis. Therefore, making sand tables by hand no longer meets the timeliness requirements of the information society. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a terrain sand table that can be quickly prepared, using materials such as foam plastics instead of sand as raw materials for composting, and based on general geographic data information, the composting area is divided into grids, Extract the elevation data of each cell, cut the piled raw materials into lengths corresponding to th...
