Getting machines to communicate
As farms get larger, producers are working to maximize the labor they have available, which often means having multiple machines at work in the same field. The challenge is that when two machines are running, coordinating their autoguidance and preventing overlap can be difficult…
Drones closer to legal use
In mid-February, the Federal Aviation Administration issued proposed rules for the use of unmanned aircraft systems, opening up the proposal for a 60-day comment period that expires in April. The rules are for UAS weighing fewer than 55 pounds.
Intercomparison of UAV, Aircraft and Satellite Remote Sensing Platforms for Precision Viticulture
Precision Viticulture is experiencing substantial growth thanks to the availability of improved and cost-effective instruments and methodologies for data acquisition and analysis, such as Unmanned Aerial Vehicles (UAV), that demonstrated to compete with traditional acquisition platforms, such as satellite and aircraft, due to low operational costs, high operational flexibility and high spatial resolution of imagery. In order to optimize the use of these technologies for precision viticulture, their technical, scientific and economic performances need to be assessed. The aim of this work is to compare NDVI surveys performed with UAV, aircraft and satellite, to assess the capability of each platform to represent the intra-vineyard vegetation spatial variability. NDVI images of two Italian vineyards were acquired simultaneously from different multi-spectral sensors on board the three platforms, and a spatial statistical framework was used to assess their degree of similarity. Moreover, the pros and cons of each technique were also assessed performing a cost analysis as a function of the scale of application. Results indicate that the different platforms provide comparable results in vineyards characterized by coarse vegetation gradients and large vegetation clusters. On the contrary, in more heterogeneous vineyards, low-resolution images fail in representing part of the intra-vineyard variability. The cost analysis showed that the adoption of UAV platform is advantageous for small areas and that a break-even point exists above five hectares; above such threshold, airborne and then satellite have lower imagery cost.
American Agri-Women Webinar
Rural policy can be a complicated topic that some think can only fully be understood by insiders. Not true, says American Agri-Women. The group is launching its new U.S. Government Affairs webinar ...

A good one… that all you IT guys will have to LOVE…
This is Alan next door. I’m sorry buddy, but I have a confession to make to you. I’ve been riddled with guilt these past few months and have been trying to pluck up the courage to tell you to your face, but I am at least now telling you in text as I can’t live with myself a moment longer without you knowing. The truth is, I have been sharing your wife, day and night when you're not around. In fact, probably more than you, particularly in the mornings after you've left for work. I haven’t been getting it at home recently, but that's no excuse I know. The temptation was just too much....I can no longer live with the guilt and I hope you will accept my sincerest apologies and forgive me. I promise that it won't happen again. Regards, Alan.
> The actions
Bob, feeling anguished and betrayed, immediately went into his bedroom, grabbed his gun, and without a word, shot his wife twice, killing her instantly. He returned to the lounge where he poured himself a stiff drink and sat down on the sofa. He took out his phone to respond to the neighbour's text and saw he had another message:

Hi Bob, This is Alan next door again. Sorry about the slight typo on my last text, I expect you worked it out anyway, but as I’m sure you noticed, my predictive text changed ‘WiFi’ To ‘Wife’. Technology hey?!? Hope you saw the funny side of that. Regards, Alan.
