Spatial data mining follows the same functions as data mining, with the end objective to find patterns in Given such additional constraints, many generalized data mining techniques and algorithms may be specially tailored for mining in spatial data. In spatial data mining, analysts use geographical or spatial information to produce business intelligence or other results. This requires specific techniques and resources to get the geographical data into relevant and useful formats. Techopedia explains Spatial Data Mining. Therefore, new techniques are required for effective and efficient data mining.

Data Mining is a process of finding potentially useful patterns from huge data sets. It is a multi-disciplinary skill that uses machine learning , statistics, and AI to extract information to evaluate future events probability. The insights derived from Data Mining are used for marketing, fraud detection, scientific discovery, etc. Data Mining is all about discovering hidden, unsuspected, and previously unknown yet valid relationships amongst the data. First, you need to understand business and client objectives. You need to define what your client wants which many times even they do not know themselves Take stock of the current data mining scenario. Factor in resources, assumption, constraints, and other significant factors into your assessment.

Businesses these days are collecting data at a very striking rate. The sources of this enormous data stream are varied. It could come from credit card transactions, publicly available customer data, data from banks and financial institutions, as well as the data that users have to provide just to use and download an application on their laptops, mobile phones, tablets, and desktops. It is not easy to store such massive amounts of data. So, many relational database servers are being continuously built for this purpose.

A spatial database is a database that is optimized for storing and querying data that represents objects defined in a geometric space. Most spatial databases allow the representation of simple geometric objects such as points, lines and polygons. Some spatial databases handle more complex structures such as 3D objects, topological coverages, linear networks, and TINs. While typical databases have developed to manage various numeric and character types of data , such databases require additional functionality to process spatial data types efficiently, and developers have often added geometry or feature data types. The Open Geospatial Consortium OGC developed the Simple Features specification first released in [1] and sets standards for adding spatial functionality to database systems. A geodatabase also geographical database and geospatial database is a database of geographic data , such as countries , administrative divisions , cities , and related information. Such databases can be useful for websites that wish to identify the locations of their visitors for customization purposes.

Daily data for temperature, wind velocity, etc. Concept hierarchies for all attributes.

We are in an age often referred to as the information age. In this information age, because we believe that information leads to power and success, and thanks to sophisticated technologies such as computers, satellites, etc. Initially, with the advent of computers and means for mass digital storage, we started collecting and storing all sorts of data, counting on the power of computers to help sort through this amalgam of information. Unfortunately, these massive collections of data stored on disparate structures very rapidly became overwhelming.
