This guide is going to demonstrate how we can use 2D GIS to visualise primary fieldwork data as proportional orientated symbols, then how we can configure the popup data and configure the time or temporal data associated with those symbols. So, we're using a ready-made map with some ready-made layers and when you first open it in ArcGIS Online after you've signed in so that you can save it later, one of the things you might need to do to start off with is to switch off this button here, the time slider. We'll use that later on. And also, click the cross to close the layers. This is because the map opens by default with these open. So, if you just shut those down, then we've got a clear start to what we're going to do. So, we can see some points with orange dots and they are the sites that we use for students to collect their field work data. We've also got the river course, which is shown. It's not complete, it's just showing the upper course of the River Ashbrooke. So, we open the river layers and we can see we've got River Ashbrooke data. If I click the little eye symbol here for visibility, you will see it disappearing and reappearing, and we're gonna click Show properties for that layer and the panel will open on the right. Now, the layer contains quite a lot of data collected under different attribute titles. So, we want to take one at a time. So, we're just going to see how we can map one of them. So, we go to Edit layer style and we're asked to choose attributes, and what we want is to choose one of the fields which selects one of the attributes. So, if we click field and scroll down till we see velocity in metres per second, and we click that and add it, and you'll see that the map will change. So, I'm just gonna tie it up the screen by shutting the Layers panel so that we can see this a bit more clearly. And what's happened is the data for velocity has been plotted and it's already showing it automatically as proportional symbols. So, let's see if we can find a symbol that's a bit more appropriate for this data. We go to the panel again on the right and we choose pick a style, and we go to the Counts and Amounts panel. There are others. Just choose the Counts and Amounts panel for style options, and then you'll see Symbol style with a pen. Click the pen just once and it will open another subpanel, if you like. If you click Basic point and then Basic shapes, it will open some more choices for us for different symbols. Scroll down to where it says Arrows, and there's a whole selection of arrows we can choose from. They've all got names over them if you float over them. But the one that I want you to select for now is this one called Arrow Cutout 2. So if we click that, the symbols should change to that. If that happens, and hopefully it has, we click Done. But before we move on, we want to change the colour. So we're going to change the Fill colour, and if we click that just once, what we can do is select a different colour. Now, you can choose the colours by just going through the panel here until you find one you like, but I'm going to suggest a hex code for one colour that seems to work quite well. And it's this one here, 004FF with the hashtag in front of it. You can see it's changed 'em to quite a bright blue. So, we're going to click done when we've done that, then we're gonna close this subpanel, Symbol style, and scroll to something called Size range, and what we can do is then change the Size range. But before we do that, just switch off this tick for Adjust size automatically, I'm going to change the lower size to 25px and the upper one to 75px. So, the symbol size is a little bit more appropriate now, we haven't got such sort of dominance by the largest one and disappearance by the smallest one. We have a range. And we're going to do one other little thing here, which is to scroll right down to the bottom of the panel on the right to something called Rotation by attribute. So, if we click that dropdown menu just there, and we're invited in this button to Rotate the symbols based on attribute values. Now, one of the values in the data is the bearing. The student recorded the bearing using a compass of where they were in the flow of the river, so we can show the direction of the flow. So if we click this once, we'll see that doesn't happen until we change the field for that, that rotation field to bearing. So, we click Bearing and let's see what happens to the symbols. You can see that they've all changed to show the direction of flow at that point in the river. That's a much better visualisation of the data about velocity. Then, what we're going to do is go to the Layers panel and our River Ashbrooke data is now showing velocity, so we're going to click the three dots for options and rename it as Velocity. We could give it a longer name but we're just gonna do that for now, and then we click OK. And if we click Legend, we can see the panel opens there and we've got a much clearer idea of what's going on. So we then save our work, and a good idea would be to slightly change the title. Up to you. I'm going to Save as for the first time, and we're gonna call it Fieldwork, could be P1 or P2 or your initials. So, I'm going to put 1 after that to save that in a different title. Our next step is to configure the popups for these symbols, so we go to the Layers panel and we make sure we go to the newly named Velocity layer, click the three dots for options, then Show properties. We see them on the right-hand side. This time we're going to click popups, which is the symbol over here. And when the panel opens, it offers us a fields list and it has a progress panel over here on the middle of the map. And by default, all the attributes are shown in this panel here. We don't really want all of them, so we click the three dots here to delete them and they will disappear, and we're left with the title, but we can change that to anything we want to. So, we can just change this title by typing something different. We're going to type River Ashbrooke but notice I've put at the end something in curly brackets, which is the site number. And that curly brackets means it's telling the GIS to pick up one of the attributes from the spreadsheet. And in this case, it's picking up the site number. So you can see for every site number, we have that showing. And in a similar way, we can add text by clicking, Add content, and then Text, and we can type a formula of words such as this. So we're picking up the Velocity attribute, but we put words on either side of it to make it make sense. So, you'll see that appearing in the popup now and we can add other things too, such as image of your chart. So if we click add content once again and click image, go to Enter a URL, and this time we're gonna pick up something directly from the data and it's going to be the image URL. So, there's a URL for an image of a photograph about that site. So if we click that, you can see that should appear in each popup. So when we've done that, we can click Done, and we can just check that each of the symbols is showing something different. We can see the different symbols there. Each of them now has a photograph. Then, we click Save and open and Save to save our work. One last thing we can do here is to use that time data we talked about earlier, so if we just shut the Layers panel and the Properties panel and we click the time slider, this little clock symbol on the right, it provides a time slider in the bottom of the screen. So, we can use that to toggle the time slider on and off. Notice it's that just a short period of time is shown here, so we need to go to the time slider options by clicking the cog on the right to change that. So, what we choose is the option in the dropdown, which enables us to show data progressively. Then, we go to time intervals and we can change the time interval. We don't have to, but we can change it to 1/4 of an hour and click the cog to close that and use either the play or fast-forward or backward buttons to display the sequence of the observations at each sample site.
