It is strictly necessary to configure a map projection when working with a total station, and even more so when combined with determinations made with GNSS. This applies to any map projection, even those that minimize the effect of the combined scale factor on projected distances.

Our colleague Frank Núñez demonstrates a Trimble R12i GNSS system in a very common operation, showing the gain in productivity without sacrificing precision, based on two fundamental elements of Trimble technology: ProPoint and TIP.

In this second part of the experience with Rumbos Geomensura, we will show the laser scanning process carried out in the field, as well as the handling of the point cloud to go from isolated scan positions to a registered and correctly georeferenced point cloud to obtain final products that represent the existing geometry.

A DA2 receiver was tested in conjunction with a Catalyst 1 subscription for the topographic representation of a property for cadastral and demarcation purposes.

One of the requirements for proper GNSS observation is to have a clear sky to achieve good tracking of the signals sent by the satellites. This requirement seems to be an unavoidable condition for GNSS; however, Trimble has introduced significant improvements in the RTK processing engine for its new GNSS receivers.

Why not consider a roving GNSS base that can broadcast differential corrections over the internet? This is precisely what Trimble R12i achieves.
