Part 1 of our article on 'BIM from a Distance' has just been published in the Surveyors Journal. This was a SCSI/ESA funded study using high resolution passive and active satellites to monitor construction in Dublin port. Part 1 introduces the problem, proposed methodology etc - Part 2 will cover the results.
This was a very interesting study to be part of - basically proving to me that high resolution satellites can measure the dimensions of structures achieving relative accuracies of +/- 0.5m. This means that the process is not entirely dissimilar from traditional methods band even more importantly is repeatable and exportable for any site worldwide. We presented these results in CIG2018 in Maynooth and again in Survey Ireland 2018 in Dunboyne.
