Title
Irrigated land area grid 2002
Date
Date
Abstract
The shapefile provides counts and densities of hectares of actually irrigated land within a hexagonal grid from data derived from the Agricultural Production Survey census final results for 2002.
Purpose
The purpose is to provide a spatial approximation of livestock numbers at a smaller geographic scale than region and territorial authority.
The shapefile provides counts and densities of irrigated land area within a hexagonal grid.
Data is derived from the Agricultural Production Survey census final results for 2002. It provides information on the hectares and density of irrigated land within a hexagonal grid. It was created by joining meshblock level data to the meshblock shapefile for the relevant year, and then aggregating and apportioning data into a vector hexagonal grid clipped to the coastline.
The attributes within the shapefile are as follows: - grid_id: the identification number of the polygon - year: the year that the data relates to ending 30 June - irrigha: the estimated hectares of irrigated land within the polygon - areakm2: the area in square kilometres within the polygon - irrigdens: the estimated irrigated land area density within the polygon (i.e. hectares irrigated per km2)
