Gaia3D has developed meteorological data mobile web service using PostgresSQL and GeoServer for weather forecaster in Korea Meteorological Administration(KMA).This system displays weather charts, weather prediction information, weather images, observation data on mobile web for rapid decision of weather forecasters when they are out of office or in remote environment. . . .
Inteligeo is a system that stores a lot of information used by the Brazilian Federal Police Forensics to fight crime, initially in the environmental arena with a later expansion to other types of crime. During the construction of the database a lot of problems appeared for which PostGIS was the . . .
Planet Labs is collecting images from dozens of satellites in order to build timely global cloud free mosaics at around 5 meter resolution. I will review
the software components we use to accomplish this, as well as discussing challenges and solutions in this process. With luck I will be . . .
Last June, GitHub announced support for GeoJSON rendering — just commit and you have a versioned, open-source map. Six months later, visual GeoJSON diffing followed suit. Since then, GitHub hosts hundreds of thousands of GeoJSON files, has served millions of maps, and has diffed tens of thousands of changes, both . . .
As the amount of scientific data continues to grow, researchers need new tools to help them visualize complex data. Immersive data-visualisations are helpful, yet fail to provide tactile feedback and sensory feedback on spatial orientation, as provided from tangible objects.
The production of a tangible representation of a scientific data . . .
We’ve rewritten OpenLayers from the ground up with the goal of offering a powerful, high-performance library leveraging the latest in web technologies. This talk will present the latest advances of the library, focusing on aspects that make OpenLayers 3 stand out. OpenLayers 3, for example, uses technologies, techniques and algorithms . . .
This presentation will demonstrate ways to take most advantage of spatial indexes, SQL constructs, and PostGIS specific functions. For these exercises we’ll be using PostGIS 2.1+ and PostgreSQL 9.3+ . We’ll demonstrate common cases people often do inefficiently.
This presentation demonstrates the following
1) Various SQL constructs including ANTI join, LEFT, . . .
This talk is about GeoCouch, a spatial extension for Couchbase and Apache CouchDB. I will give a quick introduction into Couchbase and Apache CouchDB and why they might be the ideal databases for solving your problem.
With GeoCouch it is not only possible to query your spatial data, but also your . . .
Lucene, and the NoSQL stores that leverage it, support storage and searching of polygonal records. However the spatial index implementation traditionally has returned false matches to spatial queries.
We have contributed a new spatial indexing strategy to Lucene Spatial that returns fully accurate results (i.e. exact matches only).
Better still, this . . .
Rendering maps from vector data is the next wave in custom cartography, and nowhere is this more important than on mobile devices. Modern mobile devices have high-powered GPUs for hardware-accelerated rendering and a multitude of sensors for environmental input, but also need to be keenly aware of network bandwidth constraints . . .
