A study about analysis method of "Yama-ate" in the Castle Town and Colonist City in Hokkaido

“山之门”是城堡小镇的一个主要美学特征，指的是从小镇的主要街道上可以看到冠状山顶的景观现象；然而，设计意图的城镇布局方法至今尚未得到验证。本研究以城堡镇和殖民城为例，运用GIS和GPS机制分析实际情况，对景观构成进行高精度测量，具有数学值，公正客观。然后，通过掌握街道和街道面对的山的特征，对设计进行假设研究。也就是说，如何设计主要街道作为城堡城镇的框架，如何控制洪水以修复河流和护城河，如何规划钥匙形或弯曲的道路；以及城堡大门和神社或寺庙是如何建造的，以适应轴心国。所有这些问题，在设计方法和背后的意图方面，都是要表现出来的。

"Yama-ate" is a major aesthetic feature of Castle Towns, referring to the landscaping phenomenon that the crowned mountaintop can be seen from the town's main street; yet, the methods to lay out towns with design intention is hitherto unverified.This research starts to target several cases of Castle Town and Colonist City, analyzing the actual conditions by executing GIS and GPS mechanism, which contribute high-precision measurement of the landscaping composition, with mathematic values, unbiased and objective.Then, by grasping the characters of the street and the mountain to which the street faces, it sets up a hypothetical study on the design. Namely, how was the main street designed to be the castle town's framework, the flooding control done to renovate rivers and moats, the Key-shaped or bended road planned; and how were the Castle Gate and Shrine or Temples built to fit the Axis. All these questions, in terms of design methods and the intention behind, are to be made manifest.
