| Ghana had an estimated per caput fishconsumption of 20 kg in 1993. The country'smain local sources of fish are marine catchesand, to some extent, inland fisheries from theVolta lake and rivers. Pond production formsan insignificant proportion of the national fishsupply, contributing only about 5 t.yearl.Catches from marine and inland capturefisheries have stagnated or declined in recentyears. Consequently, given high populationgrowth, fish availability will decline. |

| Google Earth is a virtual globe, map and geographical information software. It maps the Earth by the superimposition of images obtained from satellite imagery, aerial photography and GIS 3D globe. GoogleEarth® has become recently the ultimate source of spatial data and information for private and public decision-support systems. GoogleEarth is a strong tool for precision agriculture. It could be used for farm planning, field mapping, soil sampling, crop scouting, crop health monitoring, variable rate applications, and yield mapping. Also, Google Earth presents a base layer of an aerial photographic image that is geo-located. Different layers of information could be used with this base layer such as soil maps, mineral... |

| ABSTRACT: The remotely piloted aircraft (RPA) have great applicability in agriculture. Although it is a technology that has been developed for many years, in the field of agriculture it passed unnoticed for a long time. The high cost of acquisition is still a limiting factor for small and medium-sized farmers. In this way, this study had as objective to develop a low cost RPA for agriculture application. In the present study, the development and the assembly of an RPA prototype of a quadcopter type is presented, consisting of four engines and of vertical propulsion, capable of moving without human intervention, that is, autonomous flight, applied to |
