ABSTRACT

This paper illustrates a land consumption map for Italy (year 2017) at a scale 1:1,300,000, and the assessment of its changes (2012–2017). We define land consumption as the replacement of a non-artificial land cover to an artificial land cover, both permanent and no-permanent. The maps are a 10 m spatial resolution raster, produced by photointerpretation of very high resolution images and semiautomatic classification of high resolution remote sensing images. An overall accuracy of 97.7% for the map of 2012 and of 99.66% for the map of 2017 was obtained. The results suggest that the method proposed is appropriate to detect land consumption, both for the urban densification and for the sprawling phenomena, from national to local level. Furthermore, because of the high spatial resolution and the classification scheme adopted, it is suitable for an effective monitoring system, compared to other existing classification systems or monitoring programs.

摘要

本文以1：1,300,000的比例绘制了意大利（2017年）的土地消耗图，并对其变化进行了评估（2012-2017年）。我们将土地消耗定义为永久性和非永久性的非人工土地覆盖物替代人工土地覆盖物。这些地图是一个10 m的空间分辨率栅格，由非常高分辨率的图像的光解译和高分辨率遥感图像的半自动分类产生。2012年地图的总体准确性为97.7％，2017年地图的总体准确性为99.66％。结果表明，所提出的方法适用于检测从国家到地方的城市致密化和蔓延现象的土地消耗。此外，由于具有较高的空间分辨率和采用的分类方案，
