Wilderness 3a: The Bulgaria analysis

I visited Bulgaria in December 2014. Based on discussions with BBF while contributing to their GIS training I decided to do a national wilderness analysis for Bulgaria. The Bulgaria analysis was done using OpenStreetMap data.

The above map is based on publicly available vector data from the OpenStreetMap-project covering Bulgaria. A wilderness analysis based on insufficient data will only represent a map of more or less mapped areas. In this case the basis for the analysis is decent. There will still be many errors.

The analysis has not in any way been sanctioned by Bulgarian authorities. But then again, why should it be? A map like this could be made by anyone having access to encroachment data and the tools to do the analysis.

The criteria used to map the wilderness areas based on OpenStreetMap in Bulgaria is as follows:

  • Roads: primary, secondary, tertiary, unclassified, motorway, trunk
  • Land use: industrial, reservoir, military, farmland, residential, orchard, commercial, quarry, farmland and salt_pond
  • Railways
  • Waterways: canal

The choice of data representing encroachments is highly subjective. A Bulgarian might have a completely different view of what qualifies as encroachment. And based on this one might establish a constructive dialogue on land use issues.
