Three-dimensional land-use planning model

A three-dimensional land-use display model and support comprising:

• a plurality of rectangular modules having various three-dimensional surfaces representative of a contoured land surface;
• a framework for supporting said modules, said framework including means for removably and individually connecting said modules in assembled relation with aligned and contiguous corners and edges,
• said framework comprising a plurality of modular structural units each providing a horizontal planar surface to support one of said modules incorporated into said display model, said module connecting means including means for connecting each of said units to contiguous units whereby said framework is incrementally expandible;
• each of said modules including a horizontal planar undersurface, and said structural units including coextensive planar surfaces for supporting said module horizontal surfaces in a common plane;
• the vertical edges of each of said modules being planar and coextensive with said supporting structural unit so that contiguous positioning of said modules and associated support structural units provides a continuous similated contoured land surface without interstitial gaps, and individual modules are attached and removed without dislocation of adjacent modules;
• each of said modular structural units comprising an open rectangular frame supporting the associated one of said rectangular modules at the outer edges thereof;
• whereby a continuous land-use display model is formed by the assembled modules.
