Spatial querying of mineral resources using PostGIS

2019 2nd International Conference on Advancements in Computational Sciences (ICACS), 2019
Mineral 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

Management methods of spatial data based on PostGIS

open access: closed2010 Second Pacific-Asia Conference on Circuits, Communications and System, 2010
GIS 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 ...

Pg-Trajectory: A PostgreSQL/PostGIS Based Data Model for Spatiotemporal Trajectories

2016 IEEE International Conferences on Big Data and Cloud Computing (BDCloud), Social Computing and Networking (SocialCom), Sustainable Computing and Communications (SustainCom) (BDCloud-SocialCom-SustainCom), 2016
Due to the tremendous advances in GPS and location-based web services, highly available spatiotemporal trajectory data poses an important challenge - knowledge discovery from trajectories. Knowledge discovery tasks on trajectory big data such as classification, clustering and outlier detection require a dedicated data model, which can support various ...

A Storage Method for Large Scale Moving Objects Based on PostGIS

International Conference on Information Technology and Intelligent Transportation Systems, 2016
Storing and managing the large scale moving objects data is one of the research hotspots and difficulties in data mining, trajectory analyzing, location-based services and many other applications. To solve these problems, firstly we design the trajectory point representing model, the trajectory representing model, the moving object data storage model ...

A Comparative Analysis of Spatial Indexing Schemes in PostGreSQL/PostGIS Using Java-API

open access: closedInternational Journal of Emerging Research in Management and Technology, 2018
There are several indexing techniques used in retrieval of spatial data. In this paper a comparative analysis is performed on three spatial indexing techniques- GiST (Generalized Search Tree), SP_GiST (Space partition Generalized Search Tree) and R-tree (
