Actual state of contaminated sites collection based on remote sense methods in launched NIKM 2 project
Suchánek, Zdeněk ; Řeřicha, Jaroslav
In the first year of implementation of the National Inventory of Contaminated Sites (NIKM 2) project (2018-2021), the task of interpretation of the indications of contaminated sites by Remote Sensing is addressed. The methodology was developed in NIKM 1 project (2009-2012). A total of 12 CENIA´s specialists systematically pass through the territory of the Czech Republic and record the indications (signs) of contaminated sites by interpreting raster data (orthophotomaps, topographic maps, digital relief model - DMR5 etc.). The first step was to complete the knowledge base of expressions of interest objects and to refine their typology (14 types of indicia) in the form of an interpretation key (manual). The task is solved in the QGIS sw tool (freeware). For the team, a single interactive map composition has been created including the possibility of adding additional cartographic works according to current and individual needs. Workflow monitoring allows iterations of methodological knowledge to manage next work phases and statistics of interpretation results. On the basis of already performed interpretation works on an area of about 6000 km2 in 19 municipalities with extended competence, the types and numbers of indications with the knowledge from NIKM stage 1 are compared and data for the continuation of works are obtained. On the basis of the initial experience, an interpretation methodology was slightly modified. The finer differentiation of some types of interest objects and the inclusion of new map data are intended to create a better and more informative basis for field surveys. Compared to the results of the interpretation of the indices in the test areas of the first stage of NIKM, the number of indications in the majority of previously only sporadically detected types of indications increased unequivocally.

Specification of the methodology for the review of clues of contaminated sites obtained with the use of remote sensing
Suchánek, Zdeněk ; Řeřicha, Jaroslav ; Krhovský, Jan
In the initial phase of the 2nd stage of the National Inventory of Contaminated Sites (NIKM), we are focusing on the collection of clues of contaminated sites using Remote Sensing methods. Looking over the first batch (about 38,7 % of the territory is evaluated) of data recorded in the ORPs ("small districts“), we set the details of the methodology for the 2nd degree of interpretation of the clues, i.e. for the review of the data from the 1st degree of interpretation. Four reviewers (review interpreters) are involved in the review of the clues interpreted by twelve 1st degree evaluators. A simulation of three kinds of approaches to the interpretation was done in one “average” ORP. A considerable part of the clues from the 1st stage of interpretation was eliminated via unification in the case of multiplied clues, or deleted in the case of misinterpretation and/or of their little importance or insignificant interpreted volume. In some cases, retyping was applied. Final selection of clues is considered to be the result of the standardized approach of the reviewers. Comments from the discussion forms a set of recommendations for the review process.
