Design, Construction, and Evaluation of an Intelligent Frost Forecasting and Warning System

Every year, frost causes the loss of many agricultural products. There is numerous equipment to protect plants against frost. Late turning on these equipment causes inefficiency in raising the air temperature, and early turning them on will increases energy consumption and costs. Therefore, accurately forecasting frost is crucial for turning on the equipment on time. In this research, an intelligent radiation frost forecasting and warning system (IFFS) based on the Internet of Things (IoT) technology was designed and constructed. This system comprises a wireless sensor, computing, and intelligent forecasting based on deep learning methods and warning announcements to the farmer by a message. Intelligent forecasting based on forecasting dew point temperature for the next three hours according to the in-situ measurement of temperature and relative humidity of the air. The meteorological data of the studied regain from 2011-2021 were used to train the network. The IFFS Performance was evaluated. Based on the obtained results, the system accuracy in measuring temperature and relative humidity of the air was 99% and 98%, respectively. The F-score of the IFFS obtained 96%, and the system accuracy in the warning announcement obtained 100%. Finally, applying the IFFS for better protection of plants is recommended

New Generation Platforms for Exploration of Crowdsourced Geo-Data

This chapter addresses two recent topics in the field of geo-information, the former more technological and the latter more scientific. On one side, there is an emerging trend of visualizing data and their changes in space and time through multidimensional geospatial clients and/or virtual globes. In the most advanced cases, these are not simply plain viewers but also allow analysis of the data by acting as “multidimensional intelligent geo-viewers”. On the other side, citizen science is providing a great momentum to the possibility of lay people taking part in scientific development. It is a new, citizen-centred paradigm which, in most cases, takes advantage of the individual and collective augmented capability of sensing the surrounding world through the sensors that we wear. The “citizen sensors” will consciously contribute to this development, either through volunteered geographic information or by being themselves an unconscious part of the data analytics, which makes use of geo-crowdsourced data to extract information in order to create a higher level understanding of natural and manmade phenomena. This chapter seeks to outline the Web technological solutions for visualizing and analyzing such data, through a summary of the current state of the art and the original applications developed by the authors
