In this article we consider the creation of Heatmap and Interpolation with the help of OpenWebGIS interface. In the next article it is planned to describe its technical implementation using JavaScript, OpenLayers 2.x and canvas element (as part of HTML5 technology). Recently, in an article “Some new (June 2015) features and functions in OpenWebGIS”
it has been announced to revise the interpolation module completely.
This promise has been kept, and at the moment in OpenWebGIS you can
build a heatmap and make interpolation by the method of Inverse Distance Weighting (IDW).
