VMStools是一个开源软件包，使用免费软件环境R构建。专门为处理、分析和可视化商业渔业的上岸量（航海日志）和船只位置数据（VMS）而开发。分析从航海日志（EFLALO）和VMS（TACSAT）的标准化数据格式开始，使用户能够使用通用算法进行各种分析。嵌入的功能处理错误数据点的检测和删除，通过使用聚类技术进行多层识别，将日志和渔船监测系统数据连接在一起，以区分捕捞活动和其他活动，提供捕捞努力量和上岸量的高分辨率地图，内插船只轨迹，计算不同时空尺度下数据收集框架所列的捕捞影响指标。最后，数据可以转换为其他现有格式，例如填充区域数据库，如FishFrame。本文介绍了这些功能的工作流程示例，而在线材料允许一个良好的开端来执行这些分析。该软件采用了最先进的渔船监测系统和航海日志分析方法，使获取空间规划所需的泛欧甚至全世界捕鱼分布和影响指标的过程标准化。(c)2011爱思唯尔有限公司版权所有。
VMStools is a package of open-source software, build using the freeware environment R. specifically developed for the processing, analysis and visualisation of landings (logbooks) and vessel location data (VMS) from commercial fisheries. Analyses start with standardized data formats for logbook (EFLALO) and VMS (TACSAT), enabling users to conduct a variety of analyses using generic algorithms. Embedded functionality handles erroneous data point detection and removal, m tier identification through the use of clustering techniques, linking logbook and VMS data together in order to distinguish fishing from other activities, provide high-resolution maps of both fishing effort and -landings, interpolate vessel tracks, calculate indicators of fishing impact as listed under the Data Collection Framework at different spatio-temporal scales. Finally data can be transformed into other existing formats, for example to populate regional databases like FishFrame. This paper describes workflow examples of these features while online material allows a head start to perform these analyses. This software incorporates state-of-the art VMS and logbook analysing methods standardizing the process towards obtaining pan-European, or even worldwide indicators of fishing distribution and impact as required for spatial planning.
