Agricultural maps produced from earth observation data are useful at several stages in the agricultural value chain and allow farmers to make rational and comprehensive decisions when planning, planting and growing new crops. Towards this direction, a platform for the online, real-time analysis of big earth observation data for precision agriculture applications has been designed and implemented....
Multidimensional array data, such as remote-sensing imagery and timeseries, climate model simulations, telescope observations, and medical images, contribute massively to virtually all science and engineering domains, and hence play a key role in 'Big Data' challenges. Pure array storage management and analytics is relatively well understood today. However, arrays in practice never come alone, but...
This contribution introduces the forthcoming extension of the ISO SQL standard for multi-dimensional arrays, SQL/MDA. We present concepts, the language, and highlight how it can be implemented in a scalable manner. Examples used stem from Earth Observation and related domains.
Without an approach accepted by the communities at large, domain disagreements will continue to thwart current global efforts to harmonize information models. The research presented here reviewed current standardization activities. A number of observations and possible solutions are proposed to address the topic of standardizing long term access to multi-discipline Earth System archives by considering...
The use of large multidimensional, complex datasets to study the roots and the consequences of real-world phenomena is systematically gaining importance in the recent years. These datasets and their requisite metadata can be managed by query able databases, and the increasing processing capabilities of distributed computing and Array DBMS are opening new scenarios for Web-based access and analysis...
Meteorological data contribute significantly to “Big Data”, handling multi-dimensional raster data cubes up to 5-D and with single cubes up to multi-Petabyte sizes. Due to the lack of support for raster data, traditionally file-based implementations have been used for serving such data to the community, rather than databases. Array databases overcome this by providing storage and query support. In...
