Немного кода на Java
и — опля, можно прямо из ArcMap
выполнить задачу пространственного
анализа на кластере Hadoop,
показав результаты обратно в ArcMap.
In the previous
post we launched a CDH cluster on EC2 in under 5 minutes. In
this post, we will use that cluster to perform geo spatial analytics
in the form of MapReduce
and visualize the result in ArcMap.
See, ArcMap is one of the desktop tools that a GeoData Scientist will
use when working and visualizing spatial data. The use case in
my mind is something like the following: Point data is streamed
through, for example GeoEventProcessor into
Amazon S3. The user has a set polygons in ArcGIS that needs to be
spatially joined with that big data point content. The result of the
big data join is linked back to the polygon set for symbol
classification and visualization.
