A Geographic Communication Tool

Projection of GIS data on top of 3D Solid Terrain Models (3D maps) using video technology

3D maps offer an immediate perception of an area, with a clear understanding of relief, slope, aspect and visibilitygison3dmap highlights GIS data on the 3D map surface using video projectors gison3dmap syncronizes image and video presentations with GIS data projection

CCCGeomática uses 3D maps produced by Solid Terrain Modeling Inc.

What is required to put a gison3dmap system to work?

GISDatabase

Video Projector

1º – We need:• A 3D map• A GIS database• One (or more) video projectors

2º – A client which sends a drawing request to gison3dmap

3º – gison3dmap renders and projects the GIS data on the 3D map surface

gison3dmap clientsClients send projection requests to the gison3dmap controlerClients are developed using the gison3dmap API

• GIS clients, VisualSIG and ArcGIS 10, are used to explore the system ad-hoc

• GIS clients are used to capture gison3dmap projection commands for later use with the other clients

• The Powerpoint client shows slides on a multimedia display and sends projection commands, either automatically or user controlled

• gison3dmap projection commands are captured into commands text files using the GIS clients

gison3dmap clients

• Multimedia clients are used for public interaction• Projections are generally made using command text

files previously captured with a GIS client• Multimedia clients use the gison3dmap API to issue

command requests to the system• gison3dmap API requests can be integrated into any

Dot Net and OCX compatible application

• mmon3dmap is an optional multimedia client developed by CCCGeomática, which requires no programming skills

• With mmon3dmap, thematic contents organized into folders and files, are automatically seen as a menu structure

• INI files are used to define application behaviors for each folder and file

gison3dmap Architecture

There is no limit to the number of projectors that can be used with gison3dmap

Clients submit drawing requests to the system

Controller dispatches and synchronizes client requests

Calibrator is used to configure and calibrate the system

Displays control the graphic outputs used by the system for 3D map projection (P) or multimedia (M)

Controller and Display Windows

The Controller window echoes configuration, licensing and client requests

The Display window has a tab for each Display output and echoes display configuration and drawing errors

CalibrationMap Windows are used to define how the 3D map surface will be divided among video projectors

Calibration points are used to match projector coordinates (targets) with terrain coordinates (calibration points), and obtain a 3D projection solution (pose)

The number of video projectors needed will depend on 3D map size, projector resolution and aspect ratio, and required projected pixel size
