Geospatial data in library collections [PDF]

Proceedings of the 5th International Conference on PErvasive Technologies Related to Assistive Environments, 2012
While several surveys and studies focus on developing GIS services in libraries, however, there is no recent research concerning the data that academic libraries organize and offer to their users. This study tries to cover this gap, as we examine the types and forms of digital geospatial data held by academic libraries worldwide, after an investigation

Neural networks for geospatial data. [PDF]

J Am Stat Assoc
Analysis of geospatial data has traditionally been model-based, with a mean model, customarily specified as a linear regression on the covariates, and a covariance model, encoding the spatial dependence. We relax the strong assumption of linearity and propose embedding neural networks directly within the traditional geostatistical models to accommodate

Geospatial data ontology: the semantic foundation of geospatial data integration and sharing [PDF]

Big Earth Data, 2019
Effective integration and wide sharing of geospatial data is an important and basic premise to facilitate the research and applications of geographic information science. However, the semantic heterogeneity of geospatial data is a major problem that significantly hinders geospatial data integration and sharing.

Measurement of rock glacier surface change over different timescales using terrestrial laser scanning point clouds [PDF]

Earth Surface Dynamics, 2021
Topographic change at a given location usually results from multiple processes operating over different timescales. However, interpretations of surface change are often based upon single values of movement, measured over a specified time period or in a ...

Fine Classification of UAV Urban Nighttime Light Images Based on Object-Oriented Approach

Sensors, 2023
Fine classification of urban nighttime lighting is a key prerequisite step for small-scale nighttime urban research. In order to fill the gap of high-resolution urban nighttime light image classification and recognition research, this paper is based on a

Geospatial Data And Scholia [PDF]

, 2018
Scholia is a website that displays information about scientific works represented in Wikidata. It extracts the information via queries to the extended SPARQL endpoint Wikidata Query Service (WDQS). Scholia handles geospatial data that may be rendered on maps with the default map output format available in WDQS. We describe the use of geospatial data in

THE UPDATING OF GEOSPATIAL BASE DATA [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Abstract. Topopographic mapping issues concern the area coverage at different scales and their age. The age of the map is determined by the system of updating. The United Nations (UNGGIM) have attempted to track the global map coverage at various scale ranges, which has greatly improved in recent decades. However the poor state of updating of base maps
