Quantitative assessment methods are attaining special attention in geodiversity research. Procedures to map geodiversity indices have been proposed by several authors though there is no consensus on how to best apply and replicate them in diverse areas. A contribution to the quantitative mapping of geodiversity using GIS tools of quantification and classification is presented. These procedures were applied in the municipality of Miguel Pereira, Rio de Janeiro, Brazil. A quantification stage is supported by the multiparts technique, in which the geodiversity elements are considered without pondering their repetition, and by the singleparts technique, where the repetitions are counted. Geodiversity is then mapped and classified according to the MOV (maximum obtained value) that considers the highest score obtained by the sum of the geodiversity sub-indices and to the MPV (maximum possible value) defined by the sum of the maximum scores in each of the geodiversity sub-indices. The maps produced according to the singleparts tools reflect a higher difference between the minimum and maximum scores of geodiversity, and using the MPV more areas are classified with low geodiversity. Fieldwork surveys support the idea that combining the multiparts technique for geodiversity quantification with the MOV to its classification is more appropriate to characterize the geodiversity of the area. Nevertheless, using different methodological approaches may generate significantly different results, what must be taken into account when considering geodiversity as a support tool in land management.

基于GIS方法论的地球多样性指标量化与分类的探讨。

定量评估方法在地球多样性研究中正受到特别关注。几位作者已经提出了绘制地球多样性指数的程序，尽管在如何最好地在不同地区应用和复制它们尚无共识。提出了使用定量和分类的GIS工具对地球多样性进行定量绘图的贡献。这些程序已在巴西里约热内卢的Miguel Pereira市使用。量化阶段由多部分技术（其中不考虑重复性地考虑地理多样性元素）和单部分技术（对重复性进行计数）支持，在此基础上，考虑了地球多样性元素。然后根据考虑到由地球多样性子指数的总和获得的最高分的MOV（最大获得值）和由每个分部的最大分之和定义的MPV（最大可能值）对地球多样性进行映射和分类。地球多样性子索引。根据单部分工具制作的地图反映了最低的和最高的地球多样性得分之间存在较大差异，使用MPV可以将更多区域分类为低地球多样性。野外调查支持这样一种想法，即将用于地理多样性定量分析的多部分技术与MOV结合起来进行分类更适合于表征该地区的地理多样性。不过，使用不同的方法论方法可能会产生明显不同的结果，
