 * This software is a multi-platform and portable application based on

 * possible to calculate indicators «RhoMéO» to monitor quality,
 * fonctionalities and urban and agricultural pressures of wetlands.
 * Indicators are calculated using naturalist data entered and/or imported,
 * and geographic data downloaded from a geographic server.
