Abstract
The Spatial Data Infrastructure (SDI) are a set of policies, standards and procedures under which organizations and technologies interact to encourage more efficient use, management and production of geospatial data (FGDC, 1997). Access takes place by means of a website known as a geoportal, which serves as the main point of access to updated and reliable geospatial information arising or not from the official institutions that produce them. Nonetheless, the IDE geoportal structures do not match the needs of different user profiles likely to access them when seeking Geospatial Information (GI), which results in their limited use. The article submitted proposes to assess the National Spatial Data Infrastructure (INDE, in portuguese) in accordance with usability parameters, with grounds on the GeoTest Project (National Land Survey of Sweden, University of Gavle, 2012) with adaptations to the Brazilian case jointly with a subjective assessment test, the System Usability Scale (SUS). The method is based on ISO 9241-11 and divides the usability assessment into three distinct sub-parts: effectiveness, efficiency and satisfaction. The usability test provides geoportal developers with data to validate functions and a layout to improve user assistance. Hence, it is intended to assess improvements for the progress of applications in order to assist participating organizations as well as geoinformation users, by means of the percentages obtained in the tests performed.
