photogrammetry is the science of obtaining ground information in the from 2 dimensional drone/ aerial imagery to generate 3-dimensional elevation models and orthos. GIS professionals and surveyors use drone photogrammetry and accurate googleapis data to generate outputs to create a digital twin of their client's worksite. Traditional survey of these worksite would take weeks to complete with fragmented data outputs. Drone surveys along with photogrammetry has completely transformed the way surveys are performed to gain valuable insights from the worksite.
Why Drone survey is benificial for Worksite Surveys ?
The future of surveying is through the use of Drones/UAVs. Drone surveys can completely transforme the way valuable insights are collected from a worksite. its much more safer, faster and economical. Drones essentially acts as a tool to collect raw images even from the inaccesible areas to ensure safety of the surveyor, these raw images can then be processed using photogrammetric software to create a digital twin of any worksite. this will empower any worksite manager to view their workite in 2D as well as 3D.
EASE AND SPEED
You will be amazed to know that drone requires only 1-2 days for surveying depending upon shape and size of the plot, whereas, it would have required almost 1-2 weeks' time if it would have been manually surveyed.
HIGH ACCURACY
As Technology has advanced over the past few years, so too have the UAV services. Using GCP points and a
coordinate system, the data acquisition is much more
accurate than the traditional manual surveying operations. the highly
accurate data is photogrammetrically processed for the preparation of Orthos,
DEMs, etc.
IMPROVED SAFETY
As per government data from 2017, one mine worker was dying every six days in this industry. Drones have the capabilities to reduce this number to zero. No comparison can be made while dealing with the safety assured by drones in the field of surveying. Drone pilots need not be present physically while surveying inaccessible terrains. It has potentially increased safety and diminished life risks, which was not so during the age of traditional surveying.
COST SAVING
For each survey operation in the traditional survey method, huge funds are required periodically. The heavy costs incurred creates a tough atmosphere for a firm to operate. The application of photogrammetry in modern-day surveys and the epoch-making emergence of advanced drone technology have enabled a firm to cut down huge costs incurred while plot surveying.
DATA MANAGEMENT
If you are worried about the hustle and bustle involved while managing data, you can breathe a sigh of relief. The traditional survey deals with fragmented data which at times becomes extremely difficult to process and generate error-free outcomes. With drone technology, the scenario has completely changed now. Drone surveys enable the user to acquire well-knit overlapping continuous data which is very user-friendly to work with.
TRACK PROGRESS OVER TIME
Harnessing the power of photogrammetry will help you to create a digital history for your worksite. Not only will it help you over the course of time in managing the resource inflow and outflow, but also in preparing statistical workflow models to compare booms and recessions.
