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
Second InDOG Doctoral Conference, 14th October – 17th October 2013, Olomouc
Example – Phenophases of English Oak (Quercus robur)
Phenological phases

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
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

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

Second InDOG Doctoral Conference, 14th October – 17th October 2013, Olomouc
Final map of spatial phenologic regions
Second InDOG Doctoral Conference, 14th October – 17th October 2013, Olomouc
Proposal of concept of GIT support in the phenological research
Practical testing of methods of phenological data collection and spatial processing
Bring spatial approach to phenology Cooperation of experts from geoinformatic and
bioclimatology Giving of basis for the follow research and studies
