Vulnerable Soils: Sodicity Hazard
Soil sodicity hazard was digitally mapped as part of the DPIPWE Water for Profit Program to enhance identification of Enterprise Suitability by effectively incorporating a sustainability measure of vulnerable soils. The mapping shows areas where a sodicity hazard might exist if sufficient management is not applied, which could lead to soil resource degradation. Assigned classes are; Nil, Low, Moderate and High as classified ratings of a sodicity hazard index. The index was generated by combining Digital Soil Mapping (DSM) inputs of the soil properties of Exchangeable Sodium Percentage (ESP) for standard depths, with ratings developed by the DPIPWE Land Degradation and Salinity Risk assessments. The mapping covers the entire state of Tasmania at 30m resolution.

Geospatial and Data Services Manager - Acid Sulfate Soil Risk Map, Albany-Torbay (DWER-054)
공공데이터포털
Map of the risk of Acid Sulfate Soil (ASS) materials being disturbed by land development activities based on the likelihood of ASS materials occurring within soil profiles. This map was developed to assist planners in assessing whether development applications require additional conditions for sites where there is a risk of disturbing ASS. For further information phone the Contaminated Sites hotline 1300 762 982. This dataset was formerly known as Acid Sulphate Soil Risk Map, Albany-Torbay (DER-004). This dataset is no longer actively maintained by DWER.
Soil Erosion Risk
공공데이터포털
This map displays an assessment of soil erosion risk for the agricultural area of Alberta. Loss of protective residue cover through cultivation will increase the potential risk of soil erosion. The vulnerability of the soil to erosion combined with the intensity of cultivation determines the degree to which the soil may be at risk. The classes shown on the map were ranked from 0 (lowest risk) to 1 (highest risk). This resource was created in 2002 using ArcGIS.
Agriculture Resource Management and Assessment - Soil landscape land quality - Water Repellence Risk (DPIRD-014)
공공데이터포털
Water Repellence risk mapping derived from land quality attribution associated with soil-landscape mapping at the subsystem/phase level. See Resource Management Technical Report 298, Section 2.20, Department of Agriculture, 2005.
Water Erosion Risk
공공데이터포털
This map displays the risk of soil degradation by water in the agricultural region of Alberta. Water erosion is a concern because it reduces soil quality by removing soil particles and nutrients, and reduces water quality if these particles are carried into nearby water bodies. The map uses five classes to describe the water erosion risk on bare, unprotected mineral soil: negligible, low, moderate, high and severe.This resource was created using ArcGIS, originally published as a print map in 1993 .
