Creating a Heatmap using QGIS
In this tutorial, you will learn how to use QGIS in order to develop a heatmap based on a given set of point data (Kernal Density Estimation). The data corresponds to the recorded traffic incidents during year 2011 in Barcelona, Spain.

Words can't fully express how great of a teacher you are! I've gotten so much better in QGIS by following your tutorials. You not only teach the subject matter, but take time to explain every detail and process involved. Thank you!!!

Thank you for your excellent training videos. I watched many other QGIS videos before finally stumbling onto yours, which are 100% the best in the internet! I have learnt so much in one afternoon!
After a week long search I found what I wanted. Can't thank you enough for this wonderful tutorial. It's fair to say now "Knowledge not shared; is wasted"
Your lessons are very general but very specific at the same time. I don't know how you do that, but you are the great teacher!
I have being trying to create heatmap for a week, and your video had finally save me from consistent failing. Thank you so much!!!!!!! --a grateful high school student

Very cool video. Thank you for being an amazing teacher!
Did like the tutorial, well done explaining the heatmap application in QGIS
Thank you so much! Ive been looking for a turotrial in heat maps and I wonder why this video was not recommended to me . thank you agian
Awesome job on this video. I was able to create a heat map of car accidents weighted by number of pedestrians involved within New England.

Thank you very much for your instruction. I have a question about how to export the heatmap output into Tiff or GeoTiff file. If you don't mind, could you explain in here or else? Thanks in advance.
Do you know how to clip the heatmap to a shapefile polygon?
hi, how to make the heatmap more clear. I used the openstreetmap as the background map, but after generating the heatmap, the background is very blurry
thank you

The concept will be the same as this tutorial. You can use the kernel Density tool in ArcGIS (Spatial Analyst Tools -> Density -> Kernel Density) Kernel Density tool is calculating the density of features in a neighborhood around those features. So as long as you have the recorded spots in the form of points, you should be able to do this. You can do a Kernal Density estimation with line features too, but for what you have mentioned, using the points is the accurate way to go about it.
