Urban Forest Inventory and Analysis Database User Guide

Abstract

This document is a volume within the Urban Forest Inventory and Analysis Database User Guides series, written to assist individuals who access these data. The database description shows the tables and attributes (columns) contained within the database. We labeled each attribute in a database table with its column name, unabbreviated descriptive name, and a detailed description of the attribute. Attributes that we coded include a list of the codes and their meanings. Users familiar with the Forest Inventory and Analysis Database, which we use for the Nationwide Forest Inventory, will find familiar elements in this database. However, we updated this structure to enhance flexibility. We added the sample organization database table group for greater organization.
