"CITY GREEN PLAN" as a means to achieve sustainable development - GIS APPROACH
Through data merging
The information in the digitized form (such as soil map, climatic maps, topographic maps, vegetative maps, land use maps, land cover maps, etc.) can be merged with one another, in layer form, using the common database such as boundary map, village map or road maps. (28) Through this merging technique we can identify potential area to improve the green systems and set of plant list for that particular areas.
Through querying
To identifying the particular plant for particular location is needs data like functional (design) factors, environmental factors. Through developing an algorithms we can do a spatial query to find out appropriate plant for “a location “ in the city / individual plot. For example: selection of a tree list for a plot involves set of queries like,
- What are the possible plants list available for that region?
- What are the physical characteristics of the plants?
- What type of maintenances required by each plant?
- What type of building? Public or private?
- How much area available?
- What are the geophysical attributes of the sites?
- What are the functional requirements of the each space?
- For shading, for screening (view, sun), creating an out door room, aesthetic, edging the property, color, etc.
- What is the dsign requirement?
- Height of the plant, color of the plant, growth pattern, special qualities,
Design concepts, seasonal response, life, maintenance requirements, etc.
- What are the environmental goals?
- For flood control, to protect the soil, improve the soil condition, increase
Ground water recharging, improve the air quality, house the urban wild life.
All this queries involves many features i.e. point features, line features, polygon features
Methodology
Conculution
Since city green plays multiple rolls in the human landscape, integration of the CITY GREEN in our urban system would be the first step towards our sustainability. Finding appropriate city green system for healthy and effective city can be possible only through GIS / GPS, RS.
