Abstract

The use of remote technology can currently help in the development of studies considering the peculiarities of each environment, such as fish farming. With the increase in demand for fish in recent years, the expansion of productive areas of fish farms has been observed, resulting in greater territorial occupation, most of the time, in a disorganized way. The present work aimed to map the fish areas in the municipality of Santa Inês, Maranhão State. To identify the areas occupied by fish farms, the Photointerpretation Method and its recognition elements were used through the following software: Spring, QGis, Google Earth Pro and Arcview. To validate the information, on-site visits were carried out in fish farms according to the points identified using the software. According to the data obtained, the municipality of Santa Inês - MA showed an evolution in the territorial occupation of fish areas, from 22.99 hectares in 2003 to 46.84 hectares in 2011, 126.95 hectares in 2015 and 141 .86 hectares in 2017, with greater expansion in territorial occupation in the period from 2011 to 2015 (171%), with 81.25% of the mapped areas concentrated within a radius of 3 km from the municipal headquarters. Fish farms in the municipality of Santa Inês corresponded to only 0.24% of the total area of the municipality. The preparation and analysis of thematic maps of the territorial occupation of fish farming can help in the management of the areas found and i

在水产养殖区测绘中使用远程地质技术
目前,远程技术的使用可以帮助开展考虑到各种环境特点的研究,例如养鱼。近年来,随着鱼类需求的增加,养鱼场的生产面积不断扩大,在大多数情况下,以无组织的方式占用了更多的领土。目前的工作旨在绘制马兰赫州Santa Inês市鱼类分布区的地图。利用Spring、QGis、谷歌Earth Pro和Arcview等软件,利用Photointerpretation Method及其识别要素对渔场占用区域进行识别。为了验证这些信息,根据使用软件确定的点,在养鱼场进行了现场访问。根据获得的数据,Santa Inês - MA市的鱼类区域的领土占用呈演变趋势,从2003年的22.99公顷到2011年的46.84公顷,到2015年的126.95公顷和2017年的141.86公顷,2011年至2015年期间的领土占用扩大幅度更大(171%),其中81.25%的地图区域集中在距离市总部3公里的半径范围内。Santa市Inês的养鱼场只占该市总面积的0.24%。编制和分析鱼类养殖的领土占用专题地图有助于对所发现和发现的地区进行管理
