在本文中，我们提出和讨论的程序技术的框架内开发的图像大都会项目，在区域尺度上的景观建模。我们称之为“IMAGIS”，象征着在一个单一的信息系统中，两种最强大的视觉媒体-图像和地图-的联盟。IMAGIS是二维平面世界和三维透视世界之间的接口。它实现了一套专门设计的程序，以转换在GIS中描述的景观形式相当综合的2D实体，在3D空间中更精细的对象。它旨在创建广泛的景观模型，从中可以使用Atelier de Modélisation de l 'Architecture des Plantes（AMAP）软件计算出逼真的图像。AMAP是一个建模研讨会，允许用户在不同的生长阶段生成和可视化大量的植物模型。AMAP从一开始就为农学家的需求而创建，农学家寻求非常准确地模拟植物在自然或设计环境中的结构和生长行为。它现在在风景园林领域已经相当成熟。IMAGIS的目标是不同的用户群体：需要为影响评估、交流和决策目的可视化区域发展计划的规划和地理信息系统组织。虽然，它可以应用于各种各样的情况下，其内置的功能，使它特别适合郊区规划。第一部分的文件设置的IMAGIS的发展的基本原理，并侧重于广泛的景观的感知和代表性的问题。第二部分简要介绍了AMAP的特点，并介绍了IMAGIS的新功能，说明IMAGIS如何将AMAP的应用范围从植物扩展到土地覆盖。最后，对Imago大都会的研究成果进行了总结，并对今后景观过程建模的研究和发展提出了建议。
In this paper, we present and discuss the procedural technology developed in the framework of the Imago Metropolis project, to model landscapes at regional scale. We call it “IMAGIS” to symbolize the alliance, in one single information system, of the two most powerful visual media for the representation of a territory: the image and the map. IMAGIS is an interface between the 2 D world of plans and the 3 D world of perspectives. It implements a set of procedures specifically designed to transform landscape forms described in a GIS quite synthetically by 2 D entities, into much more elaborate objects in a 3 D space. It is intended for creating broad landscape models, from which photorealistic images can be computed with Atelier de Modélisation de l’Architecture des Plantes (AMAP) software. AMAP is a modeling workshop allowing users to generate and visualize a large number of plant models at various growth stages. AMAP was created from the outset for the needs of agronomists who seek to simulate very accurately the architecture and growth behavior of plants, in a natural or a designed environment. It is now quite established in the realm of landscape architecture. IMAGIS is aiming at a different community of users: the planning and GIS organizations who need to visualize regional development plans for impact assessment, communication and decision-making purposes. Although, it may be applied in a wide variety of contexts, its built-in features makes it particularly suitable for suburban planning. The first part of the paper sets the rationale for the development of IMAGIS and focuses on issues of perception and representation of broad landscapes. The second part provides a short description of AMAP’s features and introduces IMAGIS’ new functions, showing how they widen the application spectrum of AMAP from the plant to the land cover. Finally, some preliminary conclusions from Imago Metropolis are presented, that set-up the agenda for future researches and developments in the field of landscape procedural modeling.
