map-D: GPU-based Geospatial Database Analysis

The company launched last year but we never mentioned map-D before. map-D claims to offer the fastest database thanks to directly leveraging graphic cards (GPU).

From their website: “Map-D can query, analyze and visualize billions of data points in milliseconds. From gigabyte to terabyte, we marry SQL with the world’s fastest data processing pipeline. Complex machine learning, GIS and 3D animation on live streaming data are all simple with Map-D. […] Map-D is a vertically-integrated end-to-end solution for data querying, visualization and analysis. It uses the immense computational power of next generation-parallel hardware like graphics processing units (GPUs) and Intel Many-Core processors (such as the Phi card) to form the the backbone of a data processing and visualization engine, marryings the data processing and querying features of a traditional RDBMS with advanced analytic and visualization features.”

Anyone wants to provide feedback on map-D or GPU-based geospatial databases?

GeoServer 2.6.0 Released

One of the popular geospatial data server just got an update, GeoServer 2.6.0 has been released. Here’s an exhaustive list of talks on GeoServer at FOSS4G 2014.

The new features, according to the announcement:

  • WFS Cascade: WFS Cascade has been updated to use a brand new GeoTools wfs client implementation.
  • Curve support for GML and WMS: GeoServer curve support has been added for interaction with Oracle Spatial. To configure look for Linearization tolerance when configuring your layer. As outlined in the FOSS4G presentation we are seeking interested parties to implement or fund curve support for PostGIS and SQL Server.
  • Advanced Projection Handling: Considerable care has been taken in the handling of raster data across the dateline and in polar projections.
  • Coverage Views: recombine bands from different sources into a multi-band coverage (use “configure new coverage view” when creating a new layer).
  • Vector footprints support in image mosaics: you can now cut out of your images the “bad” parts using vector footprints, setup as sidecar wkb/wkt files, or as a global footprints shapefile
  • Pluggable Styles: this change allows greater integration with the CSS Extension (and opens the door for even more style languages in the future)
  • Wind Barbs and WKT Graphics: for greater creative control.
  • Printing: new implementation from our friends at MapFish (based on MapFish 2.x).
  • Scripting community module: a great new editor for editing scripts directly from the web application
  • New raster formats: NetCDF and GRIB support, for anyone dealing with multidimensional data. NetCDF is also supported as a WCS output format, and it allows to extract data hypercubes out of your WCS server. Finally, it is also possible to build multidimensional mosaics of NetCDF and GRIB files, and add to the using the harvest REST API.
  • Language and Internationalisation: Turkish support has been added and French, Korean, Polish, Romanian are all caught up with the latest developments.


China’s GlobeLand30 LULC Dataset Released

Announced last week is a newly available and free global land use land cover dataset at 30m spatial resolution. Here’s the official announcement: On the occasion of the upcoming UN climate change summit, Chinese government donates the GlobeLand30 datasets to the United Nations.

From the announcement: “For the past four years, China NASG has developed and prepared GlobeLand30, the world’s first global land cover datasets at a 30m resolution, for the years 2000 and 2010. The datasets are organized by ten major land cover classes and provide essential high resolution land cover and change information for climate change studies, environment monitoring, resource management, sustainable development, and many other societal benefit areas.”

You can head to the OpenLandService website to download the GLC30 – GlobeLand30 LULC dataset.
