Crowdsourcing is a practice of obtaining (geospatial) information from a large number of people, either paid or unpaid. Crowdsourcing is being recently used al-so in the precision agriculture domain where one of the biggest crowdsourcing de-vices are used, i.e. tractors equipped with a navigation system receiver. Obtained geospatial data from fleet monitoring in such a case comprise a tractor track to-gether with several attribute data.This paper aims at geovisualization of economi-cal attributes data on one hand, e.g. fuel consumption or time of operations, as well as ecological ones, e.g. amount of fertilizer and/or pesticide inserted into the ground in a certain place. Interactive cartographic visualization techniques were developed according to the end user needs for the economic data. Demonstration of progressive cartographic animations is provided. On the contrary, ecological data are typically visualized as interpolated surfaces. The presented FOODIE platform, one of the main outcomes of the equally-abbreviated European pro-ject, is one centralized place for all the above mentioned geovisualizations. As such, it exploits feedback from thousands of users that is depicted in the conclu-sions.
