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
Second InDOG Doctoral Conference, 14th October – 17th October 2013, Olomouc
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
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
Second InDOG Doctoral Conference, 14th October – 17th October 2013, Olomouc
11. Part 2 – Results of case study
Second InDOG Doctoral Conference, 14th October – 17th October 2013, Olomouc
12. Part 2 – Results
Second InDOG Doctoral Conference, 14th October – 17th October 2013, Olomouc
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
Second InDOG Doctoral Conference, 14th October – 17th October 2013, Olomouc
14. Phenological map
Second InDOG Doctoral Conference, 14th October – 17th October 2013, Olomouc
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
Second InDOG Doctoral Conference, 14th October – 17th October 2013, Olomouc
