Traditionally, it has been very diffi cult for an enterprise to consolidate its disparate map data into a single, seamless database, and integrate this signifi cant asset into the decision making process. For the past 30 years, organizations around the world have been capturing spatial data digitally in a wide variety of data formats. With thousands of data formats, sharing mapping data is a co...

Spatial databases form the foundation for a Spatial Data Infrastructure (SDI). For this, a spatial database should be methodically developed to accommodate its role in SDI. It is desirable to have an approach to spatial database development that considers maintenance from the early stage of database design and in a flexible way. Moreover, there is a lack of a mechanism to capture topological re...

Following a brief discussion on various aspects of data quality, possible methods are examined for the detection of errors in a spatial database. Using examples, we introduce the consistency checking method based on spatial relationships among neighboring objects and attribute relationships among map layers from different sources. Using logical relationships among spatial neighborhoods and amon...

This paper presents an overview of indexes for spatial and multimedia databases, whose indexes are often of the same kind as spatial ones. Records in spatial databases are characterized by their locations in an n-dimensional space where n is 1 or greater. A spatial database query involves finding all objects at a certain location, or finding all locations or areas occupied by a certain set of o...

Executive summary Spatial data is an inherent part of Exploration and Production (E&P) petroleum enterprises. Spatially enabling business information provides the ability to display and query spatial and non-spatial data in a Geographic Information System (GIS) using map based user interfaces. The Public Petroleum Data Model (PPDM) Association has developed a methodology to enhance an existing ...

BACKGROUND The availability of big data in healthcare and the intensive development of data reuse and georeferencing have opened up perspectives for health spatial analysis. However, fine-scale spatial studies of ecological and medical databases are limited by the change of support problem and thus a lack of spatial unit interoperability. The use of spatial disaggregation methods to solve this ...

palmprint recognition is a new biometrics system based on physiological characteristics of the palmprint, which includes rich, stable, and unique features such as lines, points, and texture. texture is one of the most important features extracted from low resolution images. in this paper, a new local descriptor, local composition derivative pattern (lcdp) is proposed to extract smartly stronger...

Today geographical databases must provide a dynamic and flexible data model. The notion of spatial view allows different, independent external interpretations of a database schema. A spatial view is an extension of the classical view concept as found in relational databases. A spatial view is a set of atoms. Each atom is defined with a set of database relations, a set of conventional spatial an...

Infrastructures like transportation, power, and pipeline networks which are characterized by a spatial embedding are known as spatial networks. Spatial networks are ubiquitous in our everyday life and used in transport, navigation, and city planning as well as in Geographical Information Systems (GIS) and other geo-spatial applications. The largely increasing amount of generated data about spat...
