EnviroAtlas - Portland, OR - Greenspace Proximity Gradient
Dataset Identification:
Resource Abstract:
In any given 1-square meter point in this EnviroAtlas dataset, the value shown gives the percentage of square meters of greenspace
within 1/4 square kilometer centered over the given point. EnviroAtlas defines green space for this city as the combination
of trees and forest, grass and herbaceous, agriculture, and both woody and emergent wetlands. This dataset was produced by
the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (http://enviroatlas.epa.gov/EnviroAtlas)
allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services
for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas)
or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in
its associated EnviroAtlas Fact Sheet (http://enviroatlas.epa.gov/EnviroAtlas/DataFactSheets).

purpose:
The purpose of this data is to show the density of greenspace throughout the EnviroAtlas community boundary and the gradients
of change in the amount of greenspace. The overall goal of EnviroAtlas is to employ and develop the best available science
to map indicators of ecosystem services production, demand, and drivers for the nation.
