Using OSTN15 with QGIS

As you may be aware, the United Kingdom has a new transformation model that is OSTN15. But why? What does it mean to the geospatial community? Without being too nerdy, tectonic plate movement means that the “model” surface (the geoid) is slowly moving away from being the best fit for the coordinate system. It has...

InSAR

How can you monitor broad-area land deformation with high precision? Why, from space, of course. Is it possible for satellites to accurately monitor the motion of landscapes with millimeter levels of precision? What about over wide areas while being frequently updated? If you scoffed in response to either of these questions, you might be surprised....
