Oil and Gas are the main products distributed by a pipeline network. The pipeline and the right-of-way are presented in almost all the Brazilian states, crossing regions with a lot of morphologic and geologic special sites, hydrologic special conditions, biological diversity, cities and land use.<\/p>\n
To guarantee the integrity of diverse involved environments, preventing and minimizing potential impacts to the environment, human safety, ESTEIO was contracted to develop a pioneer Environmental Survey in 5.085 km of pipeline right-of-ways.<\/p>\n
Data Collection<\/p>\n
ESTEIO collected a plenty of information as basic data, environment cadaster information coming from field collection to be integrated in a GIS – Geographic Information System.<\/p>\n
Basic Data<\/p>\n
The basic data consisted of existing maps GIS integration as thematic maps of geology, conservation units, geopolitical borders – States and municipal districts – and rivers, lakes and another hydrological information along the pipeline right-of-way.<\/p>\n
Field Cadaster<\/p>\n
The field cadaster was developed along the pipeline right-of-way in special sites previously classified as environmental interest and identified in aerial photos at 1:8.000 scale. These places were described in a specific form and it was taken several terrestrial photos too.<\/p>\n
The field forms and terrestrial photos were integrated in A GIS database and the regions were located in the aerial photos for a future positioning maps of Environmental Interest Point.<\/p>\n
Cartography<\/p>\n
Cartographic was used as support and other aerial survey products. Orthophotos (1:1.000) were used for detail mapping. Photo mosaics and 1:30.000 aerial photos were used for regional mappings and to update of hydrological features and road accesses.
\nAnother information were collected at city hall and other public agencies of the cities whose the pipeline right-of-ways are crossing, as following:<\/p>\n
