Everything you need to know before you start in drone surveying
Created byGuilherme Braghirolli
Last updated 5/2020
English

What you'll learn

  • Fully comprehend the workflow of drone surveying
  • Understand all the necessary theoretical structure of drone surveying
  • Identify the best weather to fly for each result necessary
  • Determine the size of the GSD required for the different drone surveying applications
  • Understand how to overcome one of the main limitation in drone surveying, that is the flight time
  • Understand the importance of the overlap and know what numbers to use in any situation
  • Comprehend the use of GCPs (Ground Control Points) and how they can bring reliability to the result

Description

The main goal of the Drone Surveying Course is to be a fast course, with all the main theoretical information, presented in a simple way. I will be showing what you need to know to start executing this kind of service, and also to better understand if you already work with it.

All the topics approached on the course are considered the main structural topics to know if you want to be able to generate reliable and high quality results.

This couse does not aim to be a full in-depth course on the matter. The information presented covers the beginner level expectations.

You can use the Q&A sections to ask more specific questions. I usually respond in one day, and there I can indicate you to some specific article or give extra explanations.

Who this course is for:

  • General Public
  • Graduated of any field with focus in surveying, cartography, geoprocessing and remote sensing
  • Surveyour Technicians/ Land Surveyours
  • Drone/UAV Pilots
