Introduction

Second InDOG Doctoral Conference, 14th October – 17th October 2013, Olomouc

Phenology is part of the bioclimatology.

Phenology is the study of periodic cycle of plants life events and how these are influenced by seasonal and interannual variations of climate.

Phenological phase of plants - Phenological phases (phenophase) is well recognizable and annually recurring state of the development of plants.

We can observe several phenophases in the growing season on each plant.

Phenology

Example – Phenophases of English Oak (Quercus robur)

Phenological mapping can express spatial aspect of data from observation

Phenological observations directly depend on climatic conditons - phenological maps can be compared with climate maps

Based on phenological map, we can also predict future phenologic development of landscape

Several methods of phenological mapping, depend on: amount of observed phenological data spatial arrangement of input data scale of mapping

Phenological mapping

Second InDOG Doctoral Conference, 14th October – 17th October 2013, Olomouc

Focused on comprehensive approach to phenological mapping of landscape

Processing and modelling phenological data and creation of geostatistical and spatial outputs

Vizualization of data by using of cartographical methods and maps

Part 1 - Concept of phenological mapping with support of GIT Part 2 - Case study - Field observation and spatial analysis of

phenological characteristics of experimental area Part 3 - Cartographic expression of phenological stages Part 4 - Creation of phenological regions of Czech Republic

Aims of Phd work

Second InDOG Doctoral Conference, 14th October – 17th October 2013, Olomouc

Gain basic knowledges from phenology Assessment of actual method of phenological research Creation of concept of phenological mapping with using of GIT

Outputs Proposal of an overall concept of phenological mapping using

methods of GIT Description on complete process - from data collection to the

evaluation of the possibility of spatial visualization

Part 1 - Concept of phenological mapping

Second InDOG Doctoral Conference, 14th October – 17th October 2013, Olomouc

Second InDOG Doctoral Conference, 14th October – 17th October 2013, Olomouc

The field collection of phenological data on experimental area for the case study

Statistical and spatial data processing and evaluation Spatial visualization of the obtained results

Outputs Statistically and spatially processed phenological characteristics

of the experimental area based on field observation Phenophases during one year – long-term Local phenological development – short term

Including comparison of the observed findings and spatial visualization in the form of maps

Part 2 – Case study on experimental area

Second InDOG Doctoral Conference, 14th October – 17th October 2013, Olomouc

Part 2 – Results of case study

Second InDOG Doctoral Conference, 14th October – 17th October 2013, Olomouc

Part 2 – Results

Second InDOG Doctoral Conference, 14th October – 17th October 2013, Olomouc

The proposal of methods for cartographic visualization, signs and composition of maps

Compilation of thematic phenological maps – Atlas of phenological conditions of Czechia

Testing of user perception of maps using the eye-tracking

Outputs Proposal of the possibilities for cartographic expression of phenological

stages Proposal of cartographic signs and visualization in the maps Maps were also tested at user perception by the eye-tracking method and

device

Part 3 - Cartographic vizualization of phenological data

Second InDOG Doctoral Conference, 14th October – 17th October 2013, Olomouc

Preparing of data for phenological regions of Czech Republic Performing of phenological region and cartographic visualization of results Interpretation of the results – spatio-temporal phenological development

Outputs The results are a phenological spatial regions of the Czech Republic with

using of geostatistical methods Verification of the achieved results Cartographic processing and visualization in the form of synthetic maps

Part 4 - Phenological spatial regions of Czech Republic
