 And in the Maps app, we have over the last several months started to form very close collaborations with the Google Earth Engine and WorldPop as well as Grid3. And through those collaborations, we've managed to gain access to a lot of additional third party or data that is produced through WorldPop and made available through the Google Earth Engine. And that is clearly displayed here on these middle layers, the population, population age, gender breakdown, the elevation map precipitation, and temperature map. And so we can do some really cool additional analyses here. Again, these data values, these layers are provided through WorldPop Google Earth Engine. These are not coming from the data that you have stored in your DHS2 instance. But some cool things we can do here. So let's look at the population age and gender breakdown. When I open this tab, you'll see that I'll have to select some groups. Let's say I want to see the total under five population, for example. So I'll select men 0 to 1, men 1 to 4, and do the same thing for women 0 to 1, 1 to 4. And then we have some aggregation methods. We have mean and sum. We also see that we have median, max, mean standard deviation of variance. But let's just leave mean and sum here for the time being. For the sake of the example, I'm going to go over to my period. We'll leave that 2020. That's the most recent available data from WorldPop. And my org units, we'll just leave that at district. Now we don't need to worry about style. We're going to come back to that. I'll click Add Layer. And this is going to take probably about five to 10 seconds because it's pulling the data from, again, WorldPop directly into your map here. So we'll just give it a second. All right, here it comes. And you can see that I have each district outlined. And if I click on that district, then I have the population provided by WorldPop for the under five population. So for example, I have people per hectare. The mean is 0.078. And the total sum is 75,441 for this district in Bali. OK, you can see I can see that for any district. I also have this key map here so that I can see where some of the under five population is clustered. And that's the heat map is based upon the legend here, which is people per hectare. A couple of cool things that we can do with this is that we can make boundaries or buffers for individual health facilities. So let me show you an example of that. I'm going to go back to my org units tab. I'm going to remove districts. And let's go to Facility. And now let's check out Style tab. I'm going to make sure that I apply a buffer. And that buffer is going to be 5,000 meters. 5 kilometers. And now I'm going to click Update. And again, 5 to 10 seconds as we pull the data from roll pop. This just got a little bit slower, probably because a lot of folks are playing around with it doing on their own right now. And now it's finally coming. And it's pulling in about 3,000 org units for this Sierra Leone demo database. And you can see that there is a 5 kilometer buffer applied to it. And as I zoom in, you can see the health facilities. You can see that 5 kilometer buffer. I click on the health facility. You can see that for the L.A. Community Health Center, they have a total under 5 population within a 5 kilometer radius of 2,770 children, male and female. Of course, this is coming from roll pop. This is not necessarily your national statistics, but it is in most cases a very verified and accurate population estimate. OK. Just to point out that we are really, this is again a new addition to DHIS 236. This is really though we're scratching the surface of what we're actually able to provide here. We very much like folks to use this play around with it. Tell us how they would like to see it and would they like to see it displayed differently. We could potentially start to explore things like facility catchments, boundaries based upon driving distance, and other geographic features. We can look at better clustering or risk projection mapping. There's just a whole lot here, and really through our collaboration with roll pop and grid 3 via Google Earth Engine, there's just a tremendous amount that we can do. And so I encourage you guys to use this feature, play around with it, and do communicate back to us how you'd like to see it improved or if we can make anything a little easier for you.
