Drone Mapping Tips & Tricks

How many GCPs do I need for drone mapping?

When it comes to geospatial data analysis and mapping, accuracy is crucial. One important tool that helps achieve high accuracy is ground control points (GCPs). In this blog post, I want to share my experience processing one of our recent datasets using different numbers of GCPs ranging from 1 to 5. Join me as we

How Artificial Intelligence helps make drone image processing smarter

  By combining AI with drone image processing, we can pinpoint the exact geographical location on earth in an efficient and consistent manner. If you search “AI”, there are more than four trillion results in Google. If you search for “AI” in news, there is a piece released almost every hour about this topic. Artificial

Moo alert! We want to create an outstanding pasture for out standing cows!

Cattle are definitely one of the rock stars in human history. They have been contributing to our society as draught animals, providing resources such as meat, milk, leather, fertiliser, by-products and as trusting companions and possessions. Why did the cow get an award? For being out-standing in the field.   (Photo by Wolfgang Hasselmann on Unsplash)

GPU vs CPU: Which One Do You Need If You Want to Learn Deep Learning

Let us explain the difference between CPU vs GPU in the process of deep learning. Recently, I had an interesting experience while training a deep learning model. To make a long story short, I’ll tell you the result first: CPU based computing took 42 minutes to train over 2000 images for one epoch, while GPU based computing only took
