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!!!

[@geodeltalabs]

Great to hear! ^_^

[@klemensjeitler3678]

your tutorials are the best qgis tutorials! Which each of them I can learn so much. And they are very comprehensible and easy to follow. Thank you so much!

[@geodeltalabs]

You are welcome :)

[@olufemioni7263]

You made QGIS so simple. Your descriptions are clear and easy to follow. I am new to GIS, and I am already feeling like I can do a lot by practicing with your tutorials. Thanks!!!

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"

[@rajkumarkrishnan7817]

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!

[@l.a2463]

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!

Did like the tutorial, well done explaining the heatmap application in QGIS

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.

[@geodeltalabs]

Great! glad to hear that :)

Very well explained..can you please also explain creating heat map through the heat map plugin.. and also how to analyse it

[@user-tp4hi6ly8q]

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.

[@mikelitoris4028]

Do you know how to clip the heatmap to a shapefile polygon?

[@user-iz6nk2ii4l]

Thank you so much.

[@geodeltalabs]

No worries!

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

[@aniketkadam8224]

Sir, I have an accident database .. so how to find accident hotspot in arc gis... sir please tell me the process?

[@geodeltalabs]

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.

SOS: Hello Sir. Thank you very much for the wonderful tutorial. I wrote my code correctly, yet my OK to validate the code wont be activated. It remaind inactive. I checked the code for errors and found non. Please see below: CASE WHEN "Descrip_vic" = 'Ferit lleu' THEN 1 WHEN "Descrip_vic" = 'Ferit greu' THEN 50 WHEN "Descrip_vic" = 'Mort' THEN 100 ELSE 0 END
