Question: How do you take a heatmap generated using a GIS software (arcgis, qgis...) and convert it into a uniform grid array of points which can be used to regenerate the heatmap (although with lesser accuracy)?
Initial to final product:
Millions of Datapoints in MySQL ->
(... some processing, maybe GIS software) -> (Final)
Hundreds of Datapoints in a grid array ->
Render density map in browser
How do I get from
Millions of Datapoints in MySQL to
Hundreds of Datapoints in a grid array?
Purpose: Transferring millions of points from database to browser where the heatmap is created will cause heavy database load and network traffic and strain the browser. So instead of transferring millions of points to the browser, it is more optimal to simplify the millions of points to 100s of points in a grid arrangement which will be easier for the browser to handle.
