Here’s what our customers say about GeoStream…

“At RCI, we provide support to a range of clients including Chartered Building Surveyors and Chartered Fire Engineers and we use Geostream daily. “It’s one of many research tools we utilise when carrying out building surveys.

“Geostream gives us access to high-quality data at an instant and the hi-resolution aerial and oblique photography are used to assist us from day one of our projects as part of our familiarisation information on buildings at the start of PAS9980 process. 

“RCI cover the entirety of the UK and utilise Geostream in combination with our in-house survey records, which spans years and include survey data that has been provided to us by a number of our clients such as Brooker Diamon Chartered Fire Engineers” 

“Together this gives us an extraordinary and unique data set which greatly benefits our clients.”
