合成地图以前曾被用于古地理重建和作为矿产勘探的辅助手段。然而，由于它们可以将风险和可行性评估中使用的不同标准联合收割机组合到一个单一的地图中，并从所有参数中获得相等或加权的输入，因此可以优化决策。该方法特别适用于滑坡灾害的评价和敏感性评估，因为它可以联合收割机通常与山区地形相关的不利因素。合成地图还具有使不同地区的预测和预防标准化的潜力。该方法与一个假设的例子和巴塔哥尼亚的一个真实的案例研究一起描述，其结果与使用随机方法对同一地区的敏感性分析进行了比较
Composite maps have previously been applied to paleogeographic reconstructions and as an aid to mineral exploration. However, because they can combine different criteria that are used in risk and feasibility assessment into a single map with equal or weighted input from all the parameters, decisionmaking can be optimized. The methodology is particularly suitable for the evaluation of landslide hazard and susceptibility assessment, as it can combine the unfavourable factors typically associated with mountainous terrains. Composite maps also have the potential to standardize prediction and prevention criteria for different areas. The methodology is described together with an hypothetical example and a real case study in Patagonia, the results of which are compared with a susceptibility analysis of the same area using stochastic methods
