 Today we'll be looking at the analysis function. Let me start by having a look in the catalogue and picking some data to work with. I'm going to choose the Water Productivity Project, and it is a continental data set, and I'm going to choose a monthly precipitation, and this is a grid cell of approximately 5 km. So let's zoom in a little bit. Let's focus down here on this area over here. So we can see that I can click on a particular point, and as usual it's looked up that exact pixel, and I've got 8 mm of rain for June 2021. So the analysis function allows us to perform some raster statistics or some analysis across multiple layers, so we're looking at a monthly data set. There's one specific chart here that's been defined for this layer called Deviation from Averages. So let's start with that one. So in terms of an area interest, I'm going to use the pixel I clicked on. So off we go, and now you'll see loading on the left hand side as it's busy calculating the values for that pixel. So what does it give me? It's given me a chart, and in this case we've got 1, 2, 3 lines. The red line is the long-term average precipitation. The green line is the 2020 precipitation, and the blue line is the 2021, and you'll see that this is monthly. So as with all the charts, we're able to sort of zoom in and see a little bit more detail if we want, and we can also reset that soon. Okay, so in this most simple case we're looking at the single pixel value, and we're investigating that. So let's try something else. Let's try now doing the same thing, but this time I'm going to create a new area. So I can create a new area by, let's zoom in a little bit, by clicking on the map and defining an area. And I'm going to say done. In fact, now you'll see I have my new area over here, area 1, and again I can pop that off to do some calculations, and now it will give me the same chart. However, the data is based on all of the pixels that lie within that area. So we can now switch between the two. I can see area 1, or I can see the point, the single location that we had earlier. So that same thing works even if I draw a polygon myself on the map. So let me try one more. I'm going to say done, I'll give that one a name. Let's call it Carl's area. Okay, so now if I click on that and I do some analysis, we should do the same thing, derivations for averages, and you see Carl's area. So now I'm able to pop that off and do some analysis. So now you'll see I have the lat-long location, the on-the-fly drawn area, and the previously drawn area. So the next thing we'll do is to look at a different way of doing it. So rather than drawing on the map, let's pretend I'm in my GIS to all of them. I have some shapes of myself somewhere. Oops, I don't remember too much. And we can also draw a shape ourselves here. So let's just draw one. Okay, and then I'm going to click on it and get a bit of title, my place, let's call it. And let's give it a red outline. And then I'm going to make it threats more or less. Okay, and let's do one more just for the sake of it. And again, let's just change that one. Make it blue or near enough blue. And again, we'll make it almost transparent. I'll give it a title. Okay, so what I'm going to do now is I'm going to save this as a GeoJSON format. So this is map 42. Now we're going to go back to the Hand in Hand Geospatial Platform. And we're going to add that GeoJSON. So if I open the explore over here and I go to my data, I can add some local data. I'm going to browse the file system and choose that GeoJSON file. And now we should see that, in fact, we see it on the map. So we have my place and another place. Okay, so now let's use one of these for doing some analysis. So we've got a precipitation layer. We say that it's got analysis. I choose a deviation from averages. And I'm going to choose another place. So I pop that off. And then you'll see that it's now busy doing the necessary calculations. And now we have the map for another place. So we can switch from area one from average and another place.
