3D Modeling of Buildings: Outstanding Sites

Management and Use of Surveys

6.1. Introduction

The creation of a 3D model of an outstanding site as described in the previous chapters is only useful if the requirements which initially motivated it can be comfortably satisfied by the users at any point. This means that the data must be available in the correct format, in the right place and at the right time. Indeed, the current surveying methods for outstanding buildings produce varied data (in nature and format), which obviously have large volumes (large quantity of images, point clouds with several million points). This becomes even more significant since as the performance of acquisition equipment and software improves, the price of digital storage gets even lower. Following the initial excitement caused by new surveying techniques (lasergrammetry and more recently “fully automatic” photogrammetry), or the possibility of participative digitization, key questions need to be answered regarding the conservation and broadcasting of these data.

6.2. Managing data conservation

The surveying methods discussed in this text can be used to produce high-quality data, by combining cutting-edge technology with procedures developed by experts experienced in the production of highly accurate metric data. It is reasonable to make the price of these data cost-effective by making it available to be shared and evolved upon. To do so, we must ensure that it is:

– consistent: data must have been purged of any intermediary versions. Moreover, ...
