Spatial querying of mineral resources using PostGIS
2019 2nd International Conference on Advancements in Computational Sciences (ICACS), 2019Mineral resources are precious resources with limited reserves. For a reasonable development of national economy, intelligent usage and management of these resources is very important. GIS has been employing specialized softwares and database technology to facilitate the storage and management of spatial data related to mineral resources. Spatial query

The Comparison of Processing Efficiency of Spatial Data for PostGIS and MongoDB Databases
Communications in Computer and Information Science, 2019This paper presents the issue of geographic data storage in NoSQL databases. The authors present the performance investigation of the non-relational database MongoDB with its built-in spatial functions in relation to the PostgreSQL database with a PostGIS spatial extension.

Extending PostGIS by imprecise point objects
IEEE 8th International Symposium on Intelligent Systems and Informatics, 2010In this paper we propose extension of PostGIS Spatial Database Management system by imprecise point object type. Position imprecision is modelled as fuzzy point in R2 linear fuzzy space. The linear fuzzy space is defined over R2 where the membership function is convex, upper semi continuous, symmetric w.r.t core, linearly decreasing w.r.t core distance,

Management methods of spatial data based on PostGIS
2010 Second Pacific-Asia Conference on Circuits, Communications and System, 2010GIS is primarily associated with spatial data. In the most GIS, the spatial data as a file, together with the attribute data, is stored in relational database. So it is difficult to keep data security data management and data consistency. PostgreSQL and PostGIS can store spatial data and attribute data in one database; this makes it easy to manage and ...

A PostGIS-based pedestrian way finding module using OpenStreetMap data [PDF]
2013 21st International Conference on Geoinformatics, 2013 Open source GIS (OSG) is a fast developing field. When OSG is combined with Web2.0 and Service Orientated Architectures (SOA) technologies and more applications of Public Participation GIS, it has many advantages over commercial GIS software. Despite this, OSG still needs more improvement in terms of stability and functional integrity.
