Discrepancy and corruption

of the Fiji Soil Map

Published on 30/04/2007


Structure

  • Introduction to Fiji soils

    2. Corruption on soil map:2.1. loss of 4000 polygons2.2. shift in the lookup tables 2.3.Discrepancys in the Map Unit Code

    2.4. LUC transfer problems


1. Introduction to Fiji soils

Fiji Soil Map is based on:

Soil Taxonomic Unit Description Handbook (STUD’s 1998) LESLIE, D.M. (David Murdoch), 1940- Fiji : soil taxonomic unit description handbook / D.M. Leslie, V.B. Seru. - Lincoln, Canterbury: Manaaki Whenua Press. 1998.Volume 1 & 2: ~ 950 pages


1. Introduction to Fiji soils

  • Classifies 227 soils of Fiji

  • Each Soil has an Individual Soil Map Unit Code

    main characteristics:

    Range of Slopes, Moisture Regime, Temperature Regime (Altitude > 600m), Texture, Mineralogy Class, Landform, parent Rock, Drainage, Erosion Risk……. etc.


1. Introduction to Fiji soils

Content:

  • Classification of the Soil Series of Fiji

    in different Systems

  • Flow-Diagram keys for the

    identification of Fiji Soil Series

  • Fiji Soil mapping units, land use capability

    classes and the main soil limitations

  • Land and Soil attributes significant

    for crop growth

  • Application of the fertility capability

    soil classification

  • Matching of soil attributes with

    crop requirements; soil suitability

    assessments


Basically ~14000 polygonseach polygon has a individual map unit code  “newseries”

2. Corruption on soil map


2.1. loss of 4000 polygons

Shapefile 24/02/1998

Shapefile 06/05/2008


2.2. shift in the lookup tables

Datasource: Landuse capability (shapefile) 27/11/2007


2.3. Discrepancys in the Map Unit Code

R Soils that should be absent on Viti Levu


LUC transfer problems

Example: Keiyasi soils (113)  113C+D are not present
