The secret to creating accurate drone maps? Planning. Take the time to plan your drone flight and create more accurate maps. Advances in technology mean it’s now possible to create highly accurate drone maps. For operators looking to improve the accuracy of their maps even further, there are a number of steps that can take your maps to an advanced level suitable for commercial purposes across industries such as agriculture, construction, mining and more.
There are several ways to improve the accuracy of your drone maps:
– Consider the Weather
– Use of high-resolution camera
– Fly at a lower altitude
– Capture ground control points
– Operate a drone with GPS system
Consider the Weather
Weather conditions greatly affect image quality, which in turn affects a map’s overall accuracy. Strive to fly while the sun is highest in the sky and avoid weather patterns such as high winds and cloud cover.
Use of high-resolution camera
One of the simplest things you can do to improve accuracy is to increase the resolution of your individual images, which can be achieved by using a high-quality camera with a powerful sensor. An image with more pixels contains more information, which means there is a greater probability of matching common points.
Fly at a lower altitude
Flying at a lower altitude serves two purposes. It captures more details in the landscape and therefore more data points to work with. Low altitude flights also result in a greater number of overall images, again increasing the probability of matching more common points on a map.
Capture ground control points
Using GCPs essentially entails creating a series of ground markers in your area of interest prior to your flight and then manually recording the GPS coordinates for those markers. Enterprise and business users now have the ability to process ground control points directly in Dronitech.
Operate a drone with GPS system
To improve global accuracy, operators can use a drone that has an RTK GPS system, such as the senseFly eBee RTK drone. This system uses a portable base station to transmit accurate GPS data directly to the drone, allowing you to know the precise coordinates of where a drone image was captured.
Every drone mapping project is unique. Some require a high level of local accuracy, while others require a high level of global accuracy.
