The fact that GML is an XML encoding allows it to be queried. In order to query a GML document we have designed a query language over GML/XML enriched with spatial operators. This query language has an underlying data model and algebra that supplies the semantics of the query language. In this paper, we propose an approach for integrating Geospatial data on the Web, stored in GML documents, usi...

Design of visual representation in geographical sciences is in most cases done within the confines of conventions or accepted practices that ensure that the visual designs adhere to, and remain within the realms of the usual and the expected. This is evident in conventional practices in cartography where map design is overwhelmingly constrained by the need for functional maps that target specif...

It is common for modern geospatial libraries to contain multiple datasets that cover the same area but differ only in some specific quality attributes (e.g., resolution and precision). This is affecting the concept of content-based geospatial queries, as simple coverage-based query mechanisms (e.g., declaring a specific area of interest) as well as theme-based query mechanisms (e.g., requesting...

Geospatial reasoning has grown larger scope in the semantic web. Increasinglymore information is geolocated,moremobile devices produce geocoded records, and more web mashups are created to convey geospatial information. Semantics can support the integration of geospatial information, track the provenance and quality of the data shown to an end user, and improve visualizations and querying of ge...

a study of substantial anthropogenic related pollution in the coastal samut prakarn province (thailand) was carried out focusing on the bang pu nature reserve (remnant mangrove wetland) using a remote sensing (geospatial) technique. statistical regression models were developed between biochemical parameters of sample point and related reflectance data obtained from satellite imagery (landsat...

The End-of-Life (EOL) stage of the first commercial wind farms is fast approaching and uncertainty remains in how to deal with their non-biodegradable Fibre Reinforced Polymer (FRP) composite turbine blades. Repurposing options could potentially delay large volumes material entering unsustainable waste streams such as landfill or incineration contribute circular economy. To plan management meth...

Finding relevant geospatial information is increasingly critical because of the growing volume of geospatial data available within the emerging "Big Data" era. Users are expecting that the availability of massive datasets will create more opportunities to uncover hidden information and answer more complex queries. This is especially the case with routing and navigation services where the abilit...
