2. Introduction
Second InDOG Doctoral Conference, 14th October – 17th October 2013, Olomouc
 Theory
 About phenology
 Spatial aspect of phenology
 PhD Thesis
 Concept of phenological mapping
 Field observation and data assessment
 Maps of phenological characteristics
 Spatial phenological regions

3.  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.

5. Phenological mapping
 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
Second InDOG Doctoral Conference, 14th October – 17th October 2013, Olomouc

6. Aims of Phd work
 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

7. Part 1 - Concept of phenological mapping
 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

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

9. Part 2 – Case study on experimental area
 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

13. Part 3 - Cartographic vizualization of phenological
data
 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

17. Part 4 - Phenological spatial regions of Czech Republic
 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
