Update of the Kutina city pedological map for spatial planning at a scale of 1: 25000

Project name: Update of the Kutina city pedological map for spatial planning at a scale of 1: 25000

Client:  City of Kutina
Period:  10/2019 – 12/2019
Funding: State budget
Location: Croatia

The aim of this project was to update the pedological and land suitability map of the city of Kutina for purposes of updating the city’s existing spatial plan. Namely, in 2003, a pedological map and a land suitability map of the city of Kutina at a scale of 1: 25,000 were made for the purpose of developing the spatial plan of that time.

Considering the numerous changes in the area, in the way of land use, the evident climate change, and what has been happening over the past 16 years, it is necessary to update the existing land suitability map.

As part of the update of the land suitability map, the updated methodology for land valuation has been applied in accordance with the new Ordinance on criteria for determining particularly valuable and valuable arable agricultural land (OG 23/2019).

The following activities were carried out within the project:

  • Land use map of the City of Kutina at a scale of 1: 25,000 was created by interpreting Sentinel 2 satellite images. These images have a pixel size of 10 m x 10 m for channels in the visible and near-infrared spectrum. For the interpretation, images from the vegetation period of 2018 and 2019 and the artificial intelligence method “Random forest” in the R-studio program were used.
  • Determination of climate, relief and soil characteristics based on existing data and research conducted in the city over the last 16 years. Spatially statistical analysis of the collected data was performed
  • Development of a pedological map at a scale of 1: 25,000
  • Description and interpretation of the features of systematic soil units (types and subtypes) and cartographic soil units. A total of 8 types of terrestrial soils and 6 types of hydromorphic soils have been identified. The 35 lower systematic units of soils, subtypes and forms were also identified. The identified systematic units are classified into 38 cartographic units.
  • Functionality assessment of the detailed drainage system on land with hydro meliorated soils by underground pipe drainage. It is estimated that the functionality of the detailed underground drainage system by pipe drainage is poor.
  • Mapping occasionally or frequently flooded areas. It was made using radar Sentinel-1 imagery in the C microwave band of the electromagnetic spectrum, of the European Space Agency (ESA). The images of the wider area of the city of Kutina from the fall of 2016 to the spring of 2019 were analyzed and interpreted in the Q-GIS ver. 3.4 and the SAGA program. The frequency and duration of flooding were determined in the observed period.
  • Land suitability was analyzed and mapped.
