1. INTRODUCTION
Walkability
Walkability is a measure of how friendly an area is to walking.
Walkability will answer following questions.
• How many facilities can we go by walking?
• How easy to reach them?
• What kinds of facilities are available in my place?
• More …..
Eco-friendly Walk Score
Eco-friendly Walk Score measures the degree of greenness(green space density) by specified circular distance based on
Normalized Different Vegetation Index (NDVI).
NDVI was calculated from Advanced Land Observation
Satellite ALOSAVNIR-2sensor).
Who can use• Local residents• Nature/Green lovers• Real estate agencies• Potential home buyers• City planners• Any spatial information users in Tsukuba City
