Este artigo apresenta o emprego de tecnologias OpenSource no desenvolvimento de um sistema de informações para
rastreamento de embarcações da frota pesqueira. Concebido para ser operado via Internet, com acesso seguro, o sistema
tem por foco central a redução de custos recorrentes associados a programas de prateleira, e na visualização de cartas
temáticas via web.
This article presents how OpenSource technology was used to develop a fishing vessels tracking system. The system
operates through Internet with secure access, and has its focus on box software cost reduction as well as in thematic
maps visualization via web.
Palavras-Chave: webgis, mapserver, tracking system.
Since 1999 the offshore fishery industry in Brazil has
invested expressive amounts of resources in searching for
alternative deep-water commercial stocks, such as monkfish and red crab. However, the industry fleet has no tradition or either is prepared to fish in deep-waters. To cope
with this problem, the Federal Government create a control program permitting rented vessels from Spain, United
Kingdom, Portugal, Germany, Russia, Japan and South
Korea to operate along the Brazilian coast. In order to
carry out this operation, all vessels must have onboard a
tracking equipment, an independent observer and to operate beyond 200 meters depth.
This paper presents how the tracking equipment works
in compliance with RASTRO, an Internet based tracking
system that was planned, developed and implanted to monitor fishing grounds (CABRAL, SPERB and TRIPODI,
2002). The result is a successful balance between the
commercial need of the fishing industry and the responsibility of the government in controlling fishing resources.
Currently, several companies have certified equipment
to provide tracking positions in compliance with RASTRO. The system collects vessels´ GPS data and displays
maps and reports on demand showing vessels engaged in
fishing activity. System access is granted to the government for auditing purposes, and to monitors of the fishing
industry who control daily operations.
Brazil is a continental country. Using the Internet was a
natural choice to reach all potential users of RASTRO.
The system was developed using the latest WebGIS and
OpenSource technologies, combining Linux, Apache,
PHP, MapServer, Oracle and Oracle Spatial (Figure 1).
Figure 1. System Architecture.
The system is structured in two modules: data retrieval and
web map navigation. Data retrieval is totally automated. All
certified tracking equipments are in communication with
inland servers that supply formatted vessel position information to the data retrieval module. This module processes data
and stores position information in GIS enabled database –
Oracle Spatial Database Objects (SDO).
Web map navigation is an interactive graphical user interface that displays layers of last positions (Figure 2) and
trace data (Figure 3) on a base map. Interface functions
are available according to the user profile and his or her
permissions. Observers can access last 24 hours of past
positions whereas government auditors have access to full
position data and to PDF report generation functions.

in Brazil. The first draft of the standard is expected to be
ready by the end of 2003. The substitution of Oracle as database for an OpenSource equivalent is also in the “future
works” agenda.

Considering the multitude of commercial tracking systems available in the worldwide market, RASTRO presents itself more as a tracking center, providing position
data in several levels for users, and building a strong appeal for integration of numerous tracking systems as it is
currently functioning today.
The idea of integration now leads the research group to
standardize tracking data capture or delivery, including
not only position information, but also further measurements like temperature, salinity, depth, and others. Undergoing work is focused in setting a long lasting standard
to aid the development of fishing vessel-tracking industry
