Métodos de evaluación de la calidad posicional en Hispanoamérica: análisis de la situación

Abstract

Positional accuracy constitutes a primordial aspect of geographic information quality in any geomatics application and a key element to get interoperability. The aim of this publication is identify the methods of positional accuracy assessment that are using in Hispano-American countries and within them, some that worked in the project: “Diagnosis of current situation of methodologies and procedures applied in geographic information quality evaluation”, funded by the Pan American Institute for Geography and History. The standards that are been applied are linked with American standards such as: EMAS, NMAS, NSSDA, PSADG. The most of these standards assume normality, but there are new trends such that opened by UNE 48002:2016, this Spanish standard opens a new framework. Finally, results of a survey about national maturity levels related with positional accuracy assessment conclude that positional-accuracy-assessment methods being applied in analyzed countries are in an initial level, with the exception of Spain and Brazil
