Multiplication, both in number and variety of databases in recent decades is a potential bottleneck in the process of decision making. Therefore, data warehouses and OLAP (Online Analytical Processing) were born respectively to archive and analyse these data at different levels of aggregation. SOLAP (Spatial OLAP) is a technology that combines OLAP and GIS techniques for spatial data. This presentation will discuss the various tools (particularly open source tools) and approaches in this new domain of geomatics. [less ▲]

Nowadays, mean 3D data aquisition techniques are photogrammetry and laserscanning. Their advantage is the huge amount of points that can be measured in a very short time on the field. Nevertheless, the post-processing associated to these techniques allowing to build a real 3D model from the clouds of points is very long. Therefore, we developed a geocodification ("field to finish") for the 3D data acquisition at a low and/or middle level of details. Despite each point is measured one by one with a total station, the user can gain a lot of time because of the almost-absence of post processing. This paper shows some of the developed techniques and tries to demonstrate the possible complementarity between geocodification, laserscanning and photogrammtry. [less ▲]
