Export FeatureClass to Hadoop, Run MapReduce, Visualize in 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 (translate)

My New Blog About Software Quality Assurance

Nowadays the hot topic is the software quality assurance within the teams in software developing companies.  And I fired up a new blog for this kind of subjects. Being an Adobe user is the possibility of considering about software issues. And this is why i post here this new blog's link. Feel free to ask any questions about this subject. It will be taken into account in new posts via my new blog.Basically the main subject is quality of software development projects. There are many tools around web and there is no specific way of doing best. I share my experiences (translate)

Latest Updates to ReDiLab - Reaction Diffusion in Stage3D and AGAL

This week sees a few new updates to ReDiLab - my Stage3D / AGAL based reaction diffusion laboratory.First off, my lovely friends at Finkk designed the funky logo above which lives in the 'about' dialog. There are two changes to the application itself:Coupled Gray Scott ReloadedI used last week's reengineered implementation of the Gray Scott model to create a new coupled Gray Scott model. This one shares shares the 'v' component in the uv2 reaction rate part of the formula. The model exhibits some really interesting phenomena: I've added two presets for a creation and destruction variation that look really nice.Gray Scott (translate)

Grails Tip: Getting JSON directly from Grails MongoDB-GORM Low Level API

One of the nice things about MongoDB is that documents are returned in JSON format. If you use the Mongo-GORM plugin, however, the driver conveniently converts the returned results into a Grails domain class instance. You then have to serialize this domain class to get a JSON result back. In this post, I will show […] (translate)

BigData: Launch CDH on EC2 from ArcMap in under 5 minutes

well....after you get all the necessary software, certificates and... setup everything correctly :-) The idea here is that I would like an ArcGIS user to just push a button from within ArcMap and have a Cloudera based Hadoop cluster started on Amazon EC2. From there on, a user can edit features in ArcMap that can be exported into that cluster to be used as an input to a MapReduce job. The output of the MapReduce job is imported back into ArcMap for further analysis. This combination of SmallData (GeoDatabase) and BigData (Hadoop) is a great fusion in a geo-data scientist arsenal.

Choosing DropWizard to deliver content within your Grails projects

In our current project, we’re using DropWizard alongside Grails. It has become a fairly significant and useful tool for building simple content delivery layers. In this post, I will try to share some of the rationale for choosing DropWizard to serve content and how it fits within a Groovy / Grails ecosystem. Our Current Project […] (translate)
