This is an example of drone mapping previously created for St. Hilare winery By ADS. Zoomed out You have your basic online aerial mapping product, they have layers for information, and are usually taken by a satellite or high altitude plane with at least 1 GPS reference point.
In recent years the ability to get low altitude high definition Aerial Photography Drone shots has evolved into a highly accurate and affordable tool for mapping on a small scale.
How this works, first we have to figure out the resolution needed to acquire the data our customers need. This map was created for a real estate listing so it is the highest resolution possible. For agricultural purposes an NDVI (Normalized Difference Vegetation Index) camera would be used, It is a near Infrared and shows plant health because the chlorophyll is reflective in this spectrum. ADS has trained in this camera use and will be employing the use of one very soon.
This shows the flight path on a Map ADS created. High resolution needs means lower altitude and a tighter grid which equates to more photos.
Every shot is taken at a 90 degree downward angle and have data such as GPS location, and telemetry data such as altitude. That makes every photo a data set for different purposes, telemetry data provides the information to create this elevation layer.
And all that GPS data, why would you need all that information so close together? Here's why, the map stitching program also has an area calculator. Measure anything you want within the boundaries of the area mapped by the drone.
Now look at the difference in resolution and detail on both sides of the street. The map created by ADS is on the left. Granted the drone has to do a LOT more work than the high altitude/low earth orbit platforms that shot the original map but the difference is astounding.
That's crazy right? An ADS mapping product viewed on a big screen is impressive. Additionally, the day after I map an area I can have the product in the customers hands. Meaning that the Intel they have will match the conditions on the ground. Allowing them to play offense instead of defense. This product has many uses from crop management to construction planning, and so much more!
