Urban parks not only form good urban landscapes as green and open spaces by themselves, but also contribute to the formation of good landscapes in the surrounding area by integrating with adjacent rivers, roads, and other facilities, as well as redevelopment projects. In light of this, we have collected examples of cooperation between urban parks, surrounding areas, and adjacent facilities to form favorable landscapes, and organized them into a collection of case studies that will be useful for future cooperation. In addition, using the case studies as a reference, a draft guideline was prepared for those in charge of maintenance and management of urban parks in municipalities, which outlines points to be noted for coordination at each stage and methods of coordination according to the characteristics of adjacent facilities, etc.

The Road side Trees in JapanⅥ

Date of Issue:2009.1
Author:Landscape and Ecology Division.

This document presents a survey of the road greening rate, number of road greening trees, tree species, etc., with the aim of understanding the current status of road greening in Japan. The road greening rate was calculated using the basic table by general traffic volume surveyed in the National Road Condition Survey (Road Traffic Census: as of April 1, 2005) conducted by the Road Bureau of the Ministry of Land, Infrastructure, Transport and Tourism. The survey covered general national roads, major regional roads, and general regional roads. The number of roadside vegetation trees, etc. was surveyed on roads that were in service as of March 31, 2007. The roads covered by the survey are those managed by the Ministry of Land, Infrastructure, Transport and Tourism, prefectures, municipalities, local road corporations, and expressway companies (East Nippon Expressway Company, Central Nippon Expressway Company, West Nippon Expressway Company, Metropolitan Expressway Company, Hanshin Expressway Company, Honshu-Shikoku Bridge Expressway Company).

Research on a method for analyzing the transition of green spaces using medium-resolution satellite images

Date of Issue:2008.3
Author:Landscape and Ecology Division.

Focusing on medium-resolution satellite data, which is available on a nationwide scale, this research was conducted to develop and organize technical methods to efficiently and effectively grasp the transition of green spaces, while confirming the accuracy and workload. In particular, the research was conducted with the aim of developing techniques to improve the accuracy to a level where the transition of individual forested areas, which have increased due to greening in urban areas, can be reliably determined. As a result, it became possible to determine the increase and decrease of green spaces with an error of less than 30% on a nationwide basis through the use of precise geometric correction and the removal of shadows.
