Remote sensing techniques applied to the coconut palm - an overview

Most of the information was obtained from Dr Gaëlle Viennois, from Join Research Unit AMAP, Cirad.

Some Qgis Toolbox allows to conduct remote sensing analysis, but they are not often used in CIRAD. At Cirad, researchers are mainly using commercial (and quite expensive) dedicated software, that works well on recent laptops with sufficient RAM (8 gigabytes), and quite large harddisk: each satellite image generally need 2-3 gigabytes. The software are:

ENVI Excellis - About 4000 USD once (windows 32 ou 64) mobile computer. one image 2-3 gigas.
E-cognition (trimble) - Payant classification d'objet

Multispectral images are needed to identify and count coconut palms. To get the satellite images:

Spot isis: one image costs about 100 USD: medium quality, multispectral image with resolution 6m ; panchromatic image with resolution 2m.

E-geos image: good quality, multispectral image with resolution 2m ; panchromatic 50 cm. Need to buy a minimum of 100 km2; when the image is already available, it cost 20-25 USD per km2; when the image needs to be acquired, the price is approximative doubled.

Dedicated Training is organized at "Maison de la Téledétection" Montpellier France.

Training on Qgis software

The QGIS software.

QGIS is a user friendly Open Source Geographic Information System (GIS) licensed under the GNU General Public License. QGIS is an official project of the Open Source Geospatial Foundation (OSGeo). It runs on Linux, Unix, Mac OSX, Windows and Android and supports numerous vector, raster, and database formats and functionalities.

Organization of data management

Create a directory: C;\GIS
then create subdirectories:

  • C:\GIS\Vietnam
  • C:\GIS\Vietnam\raster
  • C:\GIS\Vietnam\vector
  • C:\GIS\Vietnam\clim coverage
  • C:\GIS\Vietnam\maxent
  • C:\GIS\Vietnam\KMZ KML
All Qgis ans DIVA-GIS projects should preferably be stored in C:\GIS\Vietnam

The CDM software (Coconut Data Management) from Cirad



CDM (Coconut Data Management) is a software intended to manage experimental data observed on collections or experimental fields of coconut over a long period following a regular schedule. It is based on the STANTECH manual which describes the organization of field planting, data gathering, and data analysis, along with the characters to be observed. Data management is made for every palm planted in the fields. Version 3 is able to manage the database containing these palms with their identification characters, along with data concerning immature vegetative observations, leaf morphology, stem measurements, flowering dates, inflorescence morphology, fruit and bunch return, fruit component analyses, and state of the palms. As the location of every palm in the field is recorded in the database, it is possible to draw maps of the fields with geographical representation of characters. Observations are dated with year and month and it is possible to record one value per character and per month. It is possible to execute powerful queries on the database, to export data into external files, and to make statistical analysis of widely used designs.
