Considering their long trajectory in establishing the National Cartographic System, encompassing several topographic mapping projects through the last century, most of all based in photogrammetric coverages, this same territory is considered to be out of date in terms of cartographic products since the 80's decade. This out of date can be translated in numbers that can factually indicate the chaotic situation that planners and managers in general are experiencing nowadays in Brazil. In this manner, although the Brazilian territory is completely covered, since 1922, at 1:1.000.000 scale (46 charts), the most up-to-date products for this scale are from 1998, when they were updated based on remote sensing images. In the other hand, greater scales like 1:100.000, 1:50.000 and 1:25.000, which cover respectively 75%, 14 % and 1% of the Brazilian territory, are from periods comprehended between 1908 and 1985, most of them with more than 30 years old and never updated. The lack of geographic information at such important scales submits regional and local development as much as environmental management and monitoring to plans and actions based on unreliable and untrue spatial information. Initiatives from the federal government in order to solve some of the environmental management and monitoring problems, especially in the Amazon Region, have culminated on projects based exclusively on remote sensing techniques, like RADAM (Radar in Amazon) and SIVAM (Amazon Vigilance System). Another initiative relies, since 2006, on the cooperation agreement between IBGE and the Alaska Satellite Facility (ASF), aiming the distribution of remote sensing images to Federal Government agencies, research institutions and other non commercial users in Brazil. These images intend to help the acceleration of the territory mapping process and its updating, allowing more efficient governmental actions planning. In a country where cartographic development is running far away behind the social and economic ones, initiatives like these must be critically analyzed and discussed. That is the topic of this article.
