Overview

• What is GIS
• Simply put, a GIS combines layers of
  information about a place to give you a better
  understanding of that place.

3
Statement Of Work

• To create a suitable sized GIS system that
  manage 2D 3D data of the campus.

4
Key Words

• File System All the data of the GIS system is
  stored in a hierarchical file system.

Key Word

• Level Of Detail All the data for a certain
  building is classified by its level of detail.

7

• LOD0 -gt The basic information of a building
  including the ID, name, description, location,
  shape and etc. Normally they are stored in a
  single .txt file.
• LOD1 -gt The part of the map for a certain
  building in the GIS system and its begin and end
  point, which show the location of the part in the
  whole map.
• LOD2 -gt The images of the building.
• LOD3 -gt The simple 3D model of a building. It
  could be a simple box or a cylinder.
• LOD4 -gt The top view shape 3D model of a building
  with simple brick texture. Such 3D model can show
  the basic shape of a certain building.
• User-define LOD -gt

  file system.
• Add or change the 2D map of the GIS system.
• Exist from the GIS system.
• Adjust the new imported 2D map.
• Add new building.
• Delete an existed building.
• Add new level of detail for an existed building.

  building.
• Change basic figure or description for an existed
  building.
• Import file for certain level of detail of a
  building.
• Change the information of a file in the certain
  level of detail.

10
Detailed Implemented Functions (Continue)

• Delete an existed file in the certain level of
  detail.
• Make a 3D simple shape model for level 3 of
  detail of a building.
• Make top view shape 3D model for level 4 of
  detail of a building.
• View the figure or description information file.
• View the picture of a certain building.
• View the single 3D model of a building.
• View the GIS as a whole 3D model.

Structure Of Work

• There are three packages
• dataFormat The format of the basic information
  of a building.
• fileOperation The input output operation on the
  file system.
• gui The graphic user interface components.
