HEALTH INFORMATION SYSTEMS Denominator mapping

Disease mapping Risk assessment Crisis simulation

PRECISION PEST MANAGEMENT Spatial sampling strategies Spatial distribution & abundance models From area-wide to landscape Wind dispersal

VECMAP A one-stop-shop for vector mapping

The system VECMAP is a seamless system that: • Integrates the entire process of producing risk maps

from sampling to spatial modeling into a single package • Can be used by a wide range of practitioners • Includes supporting services designed to:

o Provide training o Ensure continuity o Facilitate exchanges o Manage data

Components

• Spread Aedes albopictus in Europe • Mosquito distribution and abundance in the Benelux • Mosquito diversity in Belgium • Midge distribution and abundance in Spain • Potential spread of a selected invasive species in

Benelux and Europe • Distribution and abundance of potential RVF vectors in

Southern Europe • Gap-analysis of vector distribution maps in Europe • Control of Ae. japonicus in Natoye, Belgium • Risk maps for pharmaceutical industry

Research partnership

Avia-GIS initiated EPIDEMOIST “Improving epidemiological modelling using satellite derived soil moisture proxies” in collaboration with UGent to improve presence/absence modelling of disease vectors through: 1. The integration of soil moisture proxies other than the

currently used NDVI proxy, and 2. The use of machine learning models instead of the

popular and frequently used statistical models.

Results

• Two proxies derived from MODIS visible near infrared and thermal infrared data: o Soil dryness index derived from daily surface temperatures with

topographic normalization o Apparent thermal inertia

• One proxies derived from the Advanced Synthetic Aperture Radar Wide Swath (Envisat): o ASAR WS soil moisture index
