Ecolo-GIS provided spatial analysis of temperature distribution in the Judean foothill region (Shfela in Israel) to Teperberg Winery. Maximum and minimum temperature grids of 100 x 100 meter resolution were calculated based on data received from meteorological stations in the area. Temperature grids were calculated using spatial regression in ARCGIS. Adj. R2 reached 0.92. Using these maps the winery agronomist could plan and improve irrigation in the vineyards.
