Systems and methods interacting with tabletop models are provided herein. A display system includes a tabletop model, including a horizontal display that is configured to display a two-dimensional digital map and a three-dimensional physical model that is configured to overlay the two-dimensional digital map. The display system includes a mobile device including a camera configured to generate a camera image. The mobile renders a model image of the three-dimensional digital and overlays a camera image of the tabletop model with the model image. The mobile device determines a selection of an object based on a touch position on the model image.

A system and method for generating land maps of a land area. The land maps can include two-dimensional and three-dimensional land maps. The land maps may be efficiently generated based on field data obtained by mobile machines configured to traverse the land area, with the mobile machines associated with one or more sensors. The land maps may be used to accurately and efficiently guide other mobile machines as such mobile machines traverse through or operate within the land area.

The present invention relates to a physical catchment model for a rainfall runoff experiment, characterized by being a physical catchment construction model having a structure in which a real terrain miniature is disposed at one side thereof and a developed terrain miniature is disposed at the adjacent other side thereof. According to the present invention, the rainfall runoff experiment is performed by collecting rainwater flowing out downwardly from the terrain miniatures through the application of artificial rainfall to the physical catchment model for the rainfall runoff experiment so as to easily compare and measure a change in the amount of rainwater flowing out for a predetermined time during rainfall in an undeveloped real terrain and a developed terrain, thereby enabling easy establishment of a national land use and development plan in the development planning stage for utilization of national land so that natural disasters caused by the rainfall runoff of land planned to be developed can be prevented in advance.

A map having surfaces that are depicted at different levels that are not related to topography, with boundaries between the surfaces, where the boundaries are disposed at travel ways. The travel ways form cliff faces in the map between the surfaces, with information items disposed on the cliff faces at positions corresponding to items of interest at locations along the travel ways where the information items are disposed.
