This paper proposes a comprehensive and practical approach to implement a land administration act in Sri Lanka followed by setting up a Land Administration Commission (LAC), which is a separate entity to maintain a Land Administration Database Management System in support of the land information collected and maintained by stakeholders who deal with matters related to land and its decision-making under e-governance concept. Also, It describes the operations of the four core functions: land tenure, land valuation, land use, and land development in land administration under a single sustainable national land policy, underpinned by spatial information under the e-Governance mechanism. Further, the paper identifies the stakeholders and their main responsibilities in each of the four core functions with the current issues in sharing information across stakeholders. Finally, the paper describes setting up a Land administration entity thereby empowering the LAC and introduces spatial information layers at different resolution levels in a centralized land administration spatial database to keep track of all land transactions carried out by each stakeholder. This approach will enable the top-level decision-making authority (the central level) to manage all land-related activities under one platform to contribute towards the sustainable land development of the country. It is proposed to implement this approach as a pilot activity in the district of Colombo and expand it in the entire country gradually with its output. 展开更多

This paper is the third of a series that introduces some of the main dataset resources presently shared through the GEOSS Platform. The GEOSS Platform is a brokering infrastructure that brokers more than 190 autonomous information systems and data catalogs;it was created to provide the technological tool to implement the Global Earth Observation System of Systems (GEOSS). This manuscript focuses on the analysis of Eurac Research datasets and illustrates the data publishing process to enroll the Eurac Research Data Provider to the GEOSS Platform through the administrative and technical registrations. The study provides an analysis of the GEOSS user searches for Eurac Research data in order to understand the main use of datasets of an important Data Provider. 展开更多

This paper is the second of a series that describes some of the main dataset resources presently shared through the GEOSS Platform. The GEOSS Platform was created as the technological tool to implement interoperability among the Global Earth Observation System of Systems (GEOSS);it is a brokering infrastructure that presently brokers more than 190 autonomous data catalogs and information systems. This paper is focused on the analysis of the NextGEOSS datasets describing the data publishing process from NextGEOSS to the GEOSS platform. In particular, both the administrative registration and the technical registration were taken into consideration. One of the most important data shared by the GEOSS Platform are the NextGEOSS datasets: the present study provides some insights in terms of GEOSS user searches for NextGEOSS data. 展开更多

Big Earth Data-Cube infrastructures are becoming more and more popular to provide Analysis Ready Data,especially for managing satellite time series.These infrastructures build on the concept of multidimensional data model(data hypercube)and are complex systems engaging different disciplines and expertise.For this reason,their interoperability capacity has become a challenge in the Global Change and Earth System science domains.To address this challenge,there is a pressing need in the community to reach a widely agreed definition of Data-Cube infrastructures and their key features.In this respect,a discussion has started recently about the definition of the possible facets characterizing a Data-Cube in the Earth Observation domain.This manuscript contributes to such debate by introducing a view-based model of Earth Data-Cube systems to design its infrastructural architecture and content schemas,with the final goal of enabling and facilitating interoperability.It introduces six modeling views,each of them is described according to:its main concerns,principal stakeholders,and possible patterns to be used.The manuscript considers the Business Intelligence experience with Data Warehouse and multidimensional“cubes”along with the more recent and analogous development in the Earth Observation domain,and puts forward a set of interoperability recommendations based on the modeling views. 展开更多

With the growth in the vehicle industry,autonomous driving has become a hot topic worldwide and has attracted increasing attention from both industrial and academic sectors.Maps,as pivotal geospatial information carriers,play a vital role in route planning and navigation service.Compared with conventional maps,high-definition(HD)maps possesses higher precision,richer information,and various services and are regarded as critical infrastructure for autonomous driving.However,heterogeneous HD map data standards and models have different characteristics and advantages,and thus they rarely meet all autonomous driving requirements for different driving objectives.This research presents an interoperable map data model,the Open HD Map Service Model(OHDMSM),to provide a reference for HD map development.The designed OHDMSM,which contains three data layers and a set of corresponding interfaces,demonstrates high interoperability for HD map data fusion and application.As a proof of concept,an HD map data system is implemented with all functions following the designed data model and interfaces of OHDMSM.The design and development of OHDMSM data structures,interfaces and systems will benefit data requesting,updating,and interoperation for HD map data worldwide,which can be helpful for developing autonomous driving and intelligent transportation in the Digital Earth. 展开更多

Spectral data of different rocks and minerals usually show different waveforms and absorption characteristics in visible and infrared wavelengths,which allow identification of mineral species and composition.However,massive spectra of rock/mineral on earth surface were scattered across a variety of spectral libraries world-wide,exhibiting inconsistent data structures and measurement conditions.To advance the data interoperability and the data usability,we collected data and information from six shared libraries with different format and measured field specimen in laboratory to establish an integrated rock spectral library(RockSL).Both the data quality of spectral curves and the integrity of descrip-tive metadata are considered in the integrated RockSL to be pub-lished in GitHub open-source repository.RockSL contains not only the big spectral dataset of rocks and minerals for data service(i.e.data sharing and retrieval)and geological discrimination,but also the characteristics dataset of key parameters/metadata(e.g.particle size,mineral composition and full-band signature,etc.)for explora-tion of data mining and knowledge discovery.We hope that more researchers will join to improve the availability and practical value of RockSL for remote sensing community.This article introduces the database structure and data processing workflow,and demon-strates a matching service and several examples of characteristic datasets of RockSL. 展开更多
