ipaast-czo case study: The Rinconada Estate.

Description

The interest in testing different survey methods within the framework of the IPAAST project was motivated by three objectives:

  • identifying evidence of rural life in the hinterland of the Roman colony of Augusta Emerita, with special attention to forms of resilience and diversification of agrarian activities beyond the areas of highest productivity of the alluvial plain of the Guadiana River.
  • assessing the composition and depth of soils in the area in order to evaluate the representativeness of surface finds and perform a regression analysis to assess the potential distribution of arable lands in the area from Roman times to the present.

combining geophysical methods commonly used in precision agriculture and archaeology in order to evaluate their interoperability and the complementary information they can provide.

 

Attention was focused on a sector of the estate where two elements were coincident 1) preliminary evidence suggested the estate’s highest concentration of archaeological finds. 2) land plots within the estate used for grazing where LIFE Adapt experiments were undertaken. This area encompassed approximately. 6.5 ha.

 

2 geophysical methods for the exploration were used:

  • Magnetic survey: a 2 sensors gradiometer system was used (Grad602 Bartington). Data sets:
    • RC_MAG
      • 01 Vector limits of survey area.
      • 02 Vector point file of vertices of survey area.
      • 03 Grid composite.
      • 04 Raster interpolation of magnetic data.
  • Electromagnetic induction with a EM38Mk2 by Geonics. Data sets:
    • RC_EMI01.
      • 01 Vector limits of survey area
      • 02 Vector file of point data (raw data)
      • 03 Raster interpolation of quad-phase (conductivity) 0,5m
      • 04 Raster interpolation of quad-phase (conductivity) 1m
      • 05 Raster interpolation of in-phase (magnetic susceptibility) 0,5m
      • 06 Raster interpolation of in-phase (magnetic susceptibility) 1m
    • RC_EMI02.
      • 01 Vector limits of survey area
      • 02 Vector file of point data
      • 03 Raster interpolation of quad-phase (conductivity) 0,5m
      • 04 Raster interpolation of quad-phase (conductivity) 1m
      • 05 Raster interpolation of in-phase (magnetic susceptibility) 0,5m
      • 06 Raster interpolation of in-phase (magnetic susceptibility) 1m
