Regional agricultural production statistics for 160 years using the geographic information system and the spatial analytical technique
| Resumo: | In this study, we created a continuous quantitative series that discriminate Portuguese annual production values at the district level, for about 160 years using a GIS-based spatial analytical technique. For the first time, it was obtained a series of annual production for eleven products: wheat, maize, rye, barley, oats, rice, wine, olive oil, potatoes, beans and grain. In spite of the limitations, the clarity and expressiveness of the spatial representation were observed, which allowed understanding the general characteristics of the distribution of the production and the relative densities, facilitating the reading of the data that gather information of the agricultural production for about 160 years (between 1850-2009). |
