Change in relief (Monitor Landscape)

The Relieve indicator is intended to analyse changes in the ground level of agricultural land and natural terrain in the Dutch cultural landscape over the years. With the relief indicator, it is possible to monitor the nature and distribution of relief interventions on agricultural land and on natural land. The smallest changes in height have not been taken into account for data-technical reasons. In addition, the smallest measurable changes for the monitoring of relief are not relevant, because after regular agricultural activities such as ploughs, the altitude measurements show a higher ground level. Larger changes such as the depletion of nature, or the chilling of agricultural land are visible in the analysis. The changes are shown per 500 x 500 meter grid cell. The indicator is part of the Monitor Landscape. The monitor shows the changes in our landscape on the basis of six indicators. These are: buildings, land use, openness, rising greenery, historical line elements and relief. The National Agency for Cultural Heritage, Het Kadaster, LandschapNL and Wageningen University & Research developed the Landscape Monitor on behalf of the ministries of BZK (Home Affairs), OCW (Education, Culture and Science) and LNV (Agriculture, Nature and Food Quality).本地形起伏（Relief）指标旨在解析多年来荷兰文化景观内农用地与自然地形的地表高程变化。借助该指标，可监测农用地与自然用地的地形改造措施的类型与分布情况。出于数据技术层面的考量，极小的高程变化未被纳入统计范围。此外，用于地形监测的可测极小变化并无实际参考价值：诸如耕地翻耕这类常规农业活动结束后，高程测量结果会显示地表高程升高，此类微小变化并非真实的地形起伏变动。而诸如自然用地退化、农用地压实这类较大变化，均可在分析中被观测到。所有变化均以500×500米的网格单元为单位进行展示。 该指标是景观监测系统（Monitor Landscape）的组成部分。该系统基于六大指标展示景观变化，分别为：建筑、土地利用、开阔度、植被增量、历史线状要素以及地形起伏。 本景观监测系统由国家文化遗产局、荷兰地籍局（Het Kadaster）、荷兰景观基金会（LandschapNL）以及瓦赫宁根大学及研究中心（Wageningen University & Research），受荷兰内政与王国关系部（BZK）、教育文化与科学部（OCW）以及农业自然与食品质量部（LNV）委托联合开发。
