  GeoDjango is a Django module that turns it into a web-GIS app. It is powerful as it uses geospatial engines such as GDAL, GEOS and PostGIS.  In this post, we'll be creating heat map using leaflet plugin https://github.com/Leaflet/Leaflet.heat . From our views.py , we need to create a function that can return JSON object with this format: [[ 50.5 , 30.5 , 0.2 ] , // lat, lng, intensity [ 50.6 , 30.4 , 0.5 ] , ] Below is an example: Basically, the proposed_roads query uses the Centroid function of GeoDjango, also intensity is obtain by getting the sum (change this depending on your specification or needs) based on the subquery.

Old Me: But...it works! Upon testing all its functionalities, lots of bugs I've found. Although it's not that major but still, a bug is a bug. Let's talk about history...I've been working this web application  in which I need to add multiple layers (flood events) for each river basin. So, my old me did this: if (!myflag1 && "Agaton 2014" == a) { mainit_tubay_bldg_agaton = new OpenLayers.Layer.Vector("Mainit-Tubay Agaton 2014 Affected Buildings", { strategies: [new OpenLayers.Strategy.Fixed()], eventListeners: { loadend: function(a) { map.zoomToExtent(mainit_tubay_bldg_agaton.getDataExtent()); $("#load_tabl...
