2. Introduction
Spatial data mining for Analysis and prediction of natural disasters
Spatial data mining is the application of data mining methods to spatial
data
Goal of Spatial data mining is to find patterns in data with respect to
Geography.
Can we use Spatial mining techniques to predict Natural disasters
around the world.
Natural disasters represent significant safety, economic, and security
threats, and the formalized goal focused communities on developing
adequate prevention, mitigation, response and recovery plans.

3. Introduction
Why Spatial Data Mining?
Spatial Data mining is to find interesting, potentially usef
ul, non‐trivial patterns in large spatial datasets. –
A huge volume of spatial data coming from an
increasing number of geographical sensors and
satellites.
“data rich but knowledge poor” problem in spatial analy
sis

6. history
John Snow was the first to discover that the cause of the
cholera in London was coming from a single pump. He did
this by talking to survivors and finding what well they drank
from, in collecting this spatial data , he was able to find a
pattern and the pump
So he became the first spatial data miner

8. Problems with Spatial Data Mining
the spatial data mining algorithms are not efficient. Faced
with massive database systems, spatial data mining
process appears uncertain, the possibility of errors
dimension model and problems to be solved are great,
not only increases the algorithm of the search space, but
also increased the blind searches possibility. And
therefore it must be removed with the use of domain
knowledge discovery tasks unrelated data, effectively
reducing the dimension of the problem, design a more
effective knowledge discovery algorithms.

9. Problems with spatial data mining
There is no accepted standardized spatial data mining query
language. One reason for the rapid development of database
technology is the continuous improvement and development
of a database query language, therefore, to continue to
improve and develop spatial data mining is necessary to
develop spatial data mining query language, digging the
foundation for efficient spatial data.
THIS IS NOT AN EXACT SCIENCE

DATA MINING TECHNIQUES:
The various data mining techniques are:
Statistics
Clustering
Visualization
Association
Classification & Prediction
Outlier analysis
Trend and evolution analysis
15. Climate data modelling
“it is very likely that hot extremes, heat waves, and heavy
precipitation events will continue to become more
frequent”. (IPPC, 2014)
17. Future directions
DISTRIBUTED/COLLECTIVE DATA MINING
UBIQUITOUS DATA MINING (UDM)
HYPERTEXT AND HYPERMEDIA DATA MINING
MULTIMEDIA DATA MINING
SPATIAL AND GEOGRAPHIC DATA MINING
TIME SERIES/SEQUENCE DATA MINING
CONSTRAINT- BASED DATA MINING
PHENOMENAL DATA MINING
18. Future trends
Geographic and spatial data mining: Geographical
databases are becoming increasingly common and more
detailed. They can be used for the extraction of implicit
knowledge, spatial relationships and other patterns that
are not explicit in them. One of the main challenges of
this field will be the design and architecture of the data
warehouses to store the information (given the very
particular nature of the data), as well as the integration of
heterogeneous data
19. Conclusion
Natural disasters are always going to be hard to predict but Spatial data
mining may help to save lives in the future. With the development of more
sophisticated techniques this could become more of an exact science
It is foreseeable that spatial data mining will not only promote space
science, the development of computer science, but also will enhance
human understanding of the world, the discovery of knowledge, in order to
better transform the world.
