3 Day Course for Mapping, Surveying and Photogrammetry

Introduction

Conducting topographic surveying with UAVs entails more than merely launching the drone to capture images and processing them in any photogrammetry application. The success of topographic mapping and surveying hinges not only on deploying the appropriate UAV and sensing technologies but also on possessing a knowledgeable understanding of how to effectively leverage them. Failure to do so can lead to the generation of substandard and inaccurate geospatial datasets, irrespective of the photogrammetry software utilized.

What you will gain

Perhaps the largest growing sector within the drone industry is drone surveying and mapping and it’s one where you have the potential to specialise and charge higher rates for your expertise. This course is designed for individual commercial drone operators to corporate drone-operating entities who are seeking to up-skill and expand their current service offerings by including mapping, surveying and photogrammetry applications with drones to a high degree of confidence and to high service standards that are demanded by clients.

Prior Knowledge

No prior knowledge of mapping, surveying or photogrammetry is required, attendees can be absolute beginners to experienced surveying professionals that would be utilising drones in their workflows and this broad audience spectrum will still be able to understand the information that will be conveyed and delivered by a highly-knowledgeable and experienced tutor.

The course is not restricted to specific types of drone platforms, planning software or photogrammetry processing applications, this comprehensive training course can be delivered in its 3-day format at our Sheffield venue.
