Introduction

  • Geospatial technology such as GIS, GPS and RS is being used for planning and monitoring of oil palm plantation

  • Land evaluation is a process of assessing land characteristics and determining its suitability and viability for development

  • Land development involves planning, land clearing, planting, and developing infrastuructures, road and drainage networks


Introduction

  • The GIS is a computer-based system to manipulate georeferenced data:

    • Entering, storing, manipulating, analysing and displaying spatial data

    • Decision support of oil palm natural resource development and management

  • GPS is a satellite-based radio-navigation system:

    • Collecting field data

    • Mapping of oil palm area

  • RS is the method of acquiring information without physical contact:

    • Methods include aerial photography, radar, and satellite imaging


Objectives

  • To determine the effectiveness of geospatial technologies (GPS, GIS and RS) in evaluating and developing a land for new oil palm planting.

  • To map the land and determining the extent of suitable and unsuitable areas for oil palm cultivation.

  • To determine the developmental requirements of the land in terms of blocking, road networks, terracing and number of planting points.

Study Area

  • Subdistrict of Tembeling, Pahang atgeographic location

  • (Upper left: 102° 23' 34.512"E, 4°18' 6.175"N, and Lower right: 102° 25' 16.84”E, 4° 16' 47.763" N).

Proposed MPOB Station, Jerantut


Material & Methods

  • Topographic Information

    • Kuala Tembeling map (sheet no 4061 of L7030 series)

    • Site survey map of proposed Jerantut station

  • IFSAR data pre-processing

    • Onboard aircraft data processing from an inertial measurement unit (IMU)

      • to create an interferogram (phase radar difference) to produce DSM (Digital Surface Model) – carried out by image provider

    • Data conversion

      • BIL data format was converted into GeoTIFF using Global Mapper 13

    • Co-registration / geometric correction

      • WGS 1984 was reprojected into RSO projection


Material & Methods

  • Contour and 3D analysis

    • Contour lines

      • Generated from Digital Terrain Model (DTM) using Global Mapper 13

      • Cropping/Subset to the proposed area

    • 3D analysis

      • Creating elevation, slope and terrace lines

      • Main road alignment, field road, drain, planting point

* TNB trail was not included

** Two types road was considered; main road and agriculture road

*** Included perimeter drain, perimeter road and electric fence

Results & Discussion: Road & Drainage

  • The main roads were considered as the block boundaries for the plantation in this study.

  • The roads were created in straight line for every 20 planting lines on flat land.

  • For hilly area, the road alignment cut across the terraces from the lower ground up to the hill top at 8 - 100 climbing slope.

  • Sufficient drain networks are important for low lying areas to avoid flooding. General recommendation for drain intensity is one drain for every four to eight oil palm planting lines depending on elevation and water table levels of the area.


Results & Discussion: Detailed Road Analysis

  • Density of road: 165.06 m/ha

Results & Discussion: Terrace Design

  • Double Terrace (7 - 15 °)

    - width: 3.5 to 4.5 m

    - The top terrace is the planting row while the bottom terrace is for the movement of vehicle

    - erosion control & monitor the flow of water

  • Single Terrace (16 - 24 °)

    - width: 3.5 to 4.5 m

    - known as mechanical terracing (expensive)

    - good for water conservation, prevent fertiliser wash, protect roads, easier accessibility, improve crop recovery & etc

Conclusions

  • The advancement of IFSAR data associated with GPS and GIS technology is useful for land evaluation and development for oil palm cultivation

  • The technologies can predetermine the blocking, number planting points, roads, drains, terraces, conservation areas etc. based on land topography

  • The information is useful for preparing the budget and contracts for a new oil palm plantation

  • The database developed can be used for future management and monitoring of the plantation
