GPU accelerated visual analytics

Recent months I had lot of fun working   on WebGL component called “mGL” for visualizing and filtering large amount of data in the browser. It has been used  for Incident Analyzer and Area Analyzer Smart M.Apps. Here are  2 videos of the testing app of the mGL that shows its potential.  Most interesting is the filtering part that takes place in the fragment shader. mGL itself has API that can connect to crossfilter to control filtering  or has adapter to be used with dc.js.

First video shows 400k parcels in Cincinaty  and second   400k road network in North Caroline. Both  with fast cross-filtering on several attributes. You can switch between dimensions represented by charts by clicking on their label. Map (road network) will reflects chart’s color and immediately response to changing filters on either chart or on map.second video shows 400k parcels in Cincinaty with the same behavior.




Smart M.App

  Recent months I have been authoring  “Green Space Analyzer” web app that shows modern  approach to visualize and  query   multi temporal geospatial data.  User see information in a form he can interact with and discover new patterns, phenomena or information just by very fast ‘feed-back’ of the UI response on the user input.  When user selects for example certain area, all graphs instantly animates transition to reflect selection made, this helps to  better  understand  dynamics of the change. Animation can be seen everywhere – from labels on bar chart, through colors change of the choropleth up to title summary. it creates subtle feeling of control or knowing what has changed and how it has changed. At HxGN 15 conference in   hexagon geospatial keynote, CEO Mladen Stojic showcased it as part of the  vision  called Smart M.App, worth to look at (at 52:40 starts Smart M.App demo):

Skylight UI for SONAR X1 – inspiration for geospatial desktops

This might be of your interest to see  how music production software solved the UI for many controls and options the user might want to control at the same (real!) time.   SONAR X1 actually haven’t brought any new functionality in this new version, just completely redesigned UI and build on top of this marketing campaign. Another fact I like is that they haven’t use all these fancy styles on windows that makes things look ‘nice’ like powerpoint but are not well readable or effective for eyes. To me it is kind of mixture of VisualStudio 2010 UI plus Office Ribbon bar plus good color scheme and additional tweaks to make it really usable.
