Technology has its many uses in varied fields and nowhere is it more apparent than in the sphere of establishing an effective tree counting system. It is very important in agricultural management to estimate the area under cultivation or the amount of crops under growth per unit of land. The advanced technology that has been harnessed for this is remote sensing data like satellite images that allow large tracts of land to be analysed without the need for on-ground hands-on field surveys.
It all started with GISTDA developing a method that utilised high-resolution multispectral satellite images to extract data on tree counting of oil palm trees, the main agricultural produce of Thailand. It used spatial statistics and digital image processing which proved to be almost 90% accurate when compared to manual and physical counting. This method is also compatible with other forms of aerial images such as those taken from Unmanned Aerial Vehicle (UAV).
Any technology to be acknowledged as successful must have varied applications. One of them is to estimate wooded areas or green cover and take remedial measures if it gets too thin. For example, tree removal in Melbourne is often necessary to clear large zones of forested land for new construction. Through the tree counting system, it can be estimated to what extent the de-forestation can be carried out without upsetting the fragile ecosystem.
Development of a tree counting system has done a world of good for the agricultural sector and allied scenarios
