Abstract

Captivate Spatial Modelling Research Group use a variety of remote sensing technologies across multiple frequencies of the electro-magnetic spectrum to build digital models of the Maritime Greenwich World Heritage Site. Enormous amounts of data are gathered in the form of point clouds, vast beautiful nebulae of spatial information. In order to make the quantity of data manageable, or in fact viewable, the point cloud is put through a process called decimation (Decimate means ‘To reduce markedly in amount’, ‘To inflict great destruction or damage upon:’ Decimate comes from the Latin decimare, to punish every tenth person... Decimate originally referred to the killing of every tenth person, a punishment used in the Roman army for mutinous legions. Today this meaning is commonly extended to include the killing of any large proportion of a population. AHD5). The level of decimation is determined by setting parameters to algorithms such as one known as Spatial Outlier Removal. The ensuing reduced, or punished data set can then be translated into a variety of forms and formats for viewing. That is the data view from here, from our point of view. From another point of view, say of citizen engagement or of co- creation, the punished data may be where meaning or cultural value resides. Increasingly as we work with experts in the social sciences, the issue is not the technologies of data collection, which are amazing, but the data journey - who is receiving and how do they receive?
