摘要翻译：
成本表面是一个定量的手段，分配社会，环境和工程成本，影响移动跨景观。成本曲面是路线优化和最小成本路径(LCP)计算的一个重要方面，广泛应用于计算机科学、景观生态学和能源基础设施建模等学科。线性特征是传统沿成本面路由计算的一个关键弱点，因为它们不能识别从小区移动到相邻小区是跨越线性屏障（增加成本）还是跟随走廊（减少成本）。遵循和避免线性特征可以极大地改变预测路线。在本文中，我们介绍了一种方法来解决这个“邻接”问题，使用一个搜索核来识别这些关键的障碍和走廊。我们将此方法构建到一个新的基于Java的开源软件包CostMAP（成本表面多层聚合程序）中，该软件使用搜索内核计算成本表面和成本网络。CostMAP不仅包括新的邻接能力，而且是一个多功能的多平台软件包，允许用户输入多个GIS数据层，并为开发加权成本网络设置权重和规则。我们将CostMAP的性能与传统的成本面方法进行了比较，并使用移动生态框架和碳捕获和存储(CCS)管道路由中的示例，显示了在遵循走廊和避开屏障两方面的显著性能收益。我们还证明了新软件可以直接计算全国范围内的成本表面。

英文摘要：
  Cost Surfaces are a quantitative means of assigning social, environmental, and engineering costs that impact movement across landscapes. Cost surfaces are a crucial aspect of route optimization and least cost path (LCP) calculations and are used in a wide range of disciplines including computer science, landscape ecology, and energy infrastructure modeling. Linear features present a key weakness to traditional routing calculations along costs surfaces because they cannot identify whether moving from a cell to its adjacent neighbors constitutes crossing a linear barrier (increased cost) or following a corridor (reduced cost). Following and avoiding linear features can drastically change predicted routes. In this paper, we introduce an approach to address this "adjacency" issue using a search kernel that identifies these critical barriers and corridors. We have built this approach into a new Java-based open-source software package called CostMAP (cost surface multi-layer aggregation program), which calculates cost surfaces and cost networks using the search kernel. CostMAP not only includes the new adjacency capability, it is also a versatile multi-platform package that allows users to input multiple GIS data layers and to set weights and rules for developing a weighted-cost network. We compare CostMAP performance with traditional cost surface approaches and show significant performance gains, both following corridors and avoiding barriers, using examples in a movement ecology framework and pipeline routing for carbon capture, and storage (CCS). We also demonstrate that the new software can straightforwardly calculate cost surfaces on a national scale.
