Marco Morais April 6, February 9, GIS Data. Data mining is the automated process of discovering patterns in data. The purpose is to find correlation among different datasets that are unexpected. Supermarket chains are a prime example of entities that use data mining techniques in an effort to increase sales by trying to find correlations in consumer buying practices.
In a hypothetical situation, a data miner might find a pattern that people who purchase high-end cat food also are strong purchasers of floor wax. As a result of this analysis, the supermarket might then place the pet food products in the same aisle as the household cleaners in an attempt to induce higher sales. On-Line Transaction Processing OLTP is the tradional model for enterprise data processing. In OLTP, the emphasis is on transactions involving the input, update, and retrieval of data.
On-Line Analytical Processing OLAP applications query the database to collate, summarize, and analyze its contents. Data mining augments the OLAP process by applying artificial intelligence and machine learning techniques to find previously unknown or undiscovered relationships in the data. This is different from analytical techniques in which the goal is to prove or disprove an existing hypothesis.
Spatial data mining is the application of data mining techniques to spatial data. Spatial data mining follows along the same functions in data mining, with the end objective to find patterns in geography.

Spatiotemporal data, dynamic data, and location-aware computing present important opportunities for research in the geospatial database and data mining arenas. Current database techniques use very simple representations of geographic objects and relationships e.
Data structures, queries, indexes, and algorithms need to be expanded to handle other geographic objects e. One of the most serious challenges is integrating time into database representations. Another is integrating geospatial data sets from multiple sources often with varied formats, semantics, precision, coordinate systems, and so forth. Data mining is an iterative process that attempts to extract from data useful information, patterns, and trends that were previously unknown.
Although data mining is a relatively new area of research, its roots lie in several more established disciplines, including database management, machine learning, statistics, high-performance computing, and information retrieval. The main impetus behind the growth of data mining was the need to synthesize huge amounts of data into knowledge. Despite the importance and proliferation of geospatial data, most research in data mining has focused on transactional or documentary data.
This chapter explores the current state of research and key future challenges in geospatial databases, algorithms, and geospatial data mining. Advances in these areas could have a great effect on how geospatial data are accessed and mined to facilitate knowledge discovery. This section outlines key developments in database management systems and data mining technologies as they relate to geospatial data.

There are many industries that require detailed knowledge of geography, geology or spatial measurements, but few businesses have quite the same intimate relationship with the surrounding landscape — above and below the surface — as mining. Burrowing under the earth or scraping over its surface in search of resources is an intrinsically spatial activity, and as such, the effective collection and presentation of geospatial data is an indispensable part of the operation.
Central to these efforts are geographic information systems GIS , which are designed to collate, analyse and display massive volumes of geographic data, replacing paper surveys and giving mining companies a clearer and more thorough bank of information to press ahead with operations. GIS technology, and digital data in general, has become increasingly central to the industry over the years, as it reduces risks by tracking geographic variables that might otherwise have been missed.
GIS is now commonly used in almost all aspects of mining, from initial exploration to geological analysis, production, sustainability and regulatory compliance. Its flagship ArcGIS system is used in numerous sectors, including mining. Alex Miller: Esri Canada provides enterprise GIS solutions and services that mining companies use to better manage every stage of their operations — from discovery to production to mine closure and reclamation.
Our ArcGIS platform integrates with other systems to bring diverse datasets together. These range from basic geological maps, satellite and geophysical imagery to operational data. Users can effectively and accurately explore and calculate economic potential, manage risk, conduct environmental assessments and analyse other concerns affecting mining and exploration. These include ArcGIS Spatial Analyst, which improves analysis by allowing users to quickly and effectively explore data as raster surfaces with tools such as interpolation and site suitability.
It also enables users to integrate cell-based raster data with traditional vector data sources. We also offer ArcGIS Geostatistical Analyst, which allows geologists to create sophisticated surfaces from data measurements occurring over an area where collecting information for every location would be impossible. It enables users to predict and model spatial phenomena based on statistics and incorporating powerful data exploration tools.

Data mining includes the utilization of refined data analysis tools to find previously unknown, valid patterns and relationships in huge data sets. These tools can incorporate statistical models, machine learning techniques, and mathematical algorithms, such as neural networks or decision trees. Thus, data mining incorporates analysis and prediction.
Depending on various methods and technologies from the intersection of machine learning, database management, and statistics, professionals in data mining have devoted their careers to better understanding how to process and make conclusions from the huge amount of data, but what are the methods they use to make it happen? In recent data mining projects, various major data mining techniques have been developed and used, including association, classification, clustering, prediction, sequential patterns, and regression.
This technique is used to obtain important and relevant information about data and metadata. This data mining technique helps to classify data in different classes. Clustering is a division of information into groups of connected objects. Describing the data by a few clusters mainly loses certain confine details, but accomplishes improvement. It models data by its clusters.

PDF Version View Text Only Version. AbstractSpatial data mining is the process in which we extract interesting i. Extracting the useful and interesting patterns from the spatial datasets is more difficult due to the complexity of the spatial data types and spatial relationships. There has been a tremendous increase in the amount of spatial data and its application to different fields like in remote sensing, medical sciences, computer cartography, geographic information systems etc.
Many techniques have been designed for the spatial data mining like decision tree and classification. Clustering is the most widely used technique for the spatial data mining. Index Terms with respect to, database management system, density based spatial clustering of applications with noise, varied density based spatial clustering of applications with noise, partitioning around medoids.
Mining is defined as the process to extract useful and implicitly stated information. Mining can be performed on different types of databases like relational databases which consist of a collection of interrelated data in the form of tables and a set of software programs to manage and access the data , transactional databases which consists of the files where each record represents a transaction and a transaction includes a unique transaction id and a set of items , temporal databases that store the relational data involving time related attributes like timestamps , sequence databases that store the sequence of the ordered events with or without the time related attributes , spatial databases that contain space related information like geographic databases, very large-scale integration VLSI or computer-aided design databases , time series databases that store sequences of events obtained over repeated intervals of time like weekly, monthly, hourly etc.
Data mining includes the techniques and methods from various fields like machine learning, database systems, statistics etc. A major challenge in spatial data mining is the efficiency of the algorithms present for the spatial data mining due to the presence of large amount of data related to space. Spatial data mining methods are applied in order to extract useful and interesting information from large spatial databases.
Spatial data mining can also be used to. Our focus in this paper is on spatial databases and spatial data mining in order to understand the various spatial data mining methods available, their applicability in different situations and their strengths and weaknesses.
