Abstract :Remote sensing is a method of monitoring the natural heterogeneity of vegetation. Although satellite based remote sensing has been a popular method for monitoring the earth`s surface, it has several drawbacks, such as the orbital period, unattended capture, and investment cost. On the other hand, an unmanned air vehicle insert ignore into journalissuearticles values(UAV); is more flexible in terms of deployment, monitoring a small area, and being easy to obtain at a low cost. From this point of view, the goal of this research was to develop a low cost and easy to implement technical solution for mapping spatial heterogeneity and research its relationship with plant conditions. The intention was to develop a cycling process starting with a UAV-based image-capturing tool for an easy and reasonable production of a normalized difference vegetation index insert ignore into journalissuearticles values(NDVI); and the resulting prescription maps, especially of vineyards. The main parts of this image acquisition system were the UAV and modified digital cameras purchased from the store. Two different fixed-winged UAVs were built for this study based on commercial airplane models and used open source autopilot. Two small digital cameras insert ignore into journalissuearticles values(Nikon and Canon); were tested for capturing the images. These were modified to capture electromagnetic energy ranging from 380 nm to 1100 nm. Camera calibration tests were conducted and a UAV-based image acquisition system was successfully developed. In the next step, future field tests will be conducted to assess the practical usage of running the cycling process.
