 Hi again everyone. My name is Andres. I'm part of the Android team. Today I'm going to talk to you about geospatial considerations in the Android application mainly. So as you know, we have ways to capture coordinates in the HIs2 in different concepts. One is the track entity instance. The other one is in enrollments, in events, for program stages, data elements or attributes, and in our unit which is not supported visualization in Android. The first and main thing in order to be able to capture coordinates and geospatial information is to enable the location in the device. It can be super obvious but it's important to make it clear because sometimes for privacy we have it disabled. So it's important. The way we can capture coordinates are two in the Android app. The first one is via polygons which is the representation of an area defined by several coordinates. As you can see in the screenshot you can define a coordinate via some an area, sorry, via some coordinates and it's the way we can set an area. The other one is a geographic point, a lot long. That's like a single coordinate which is the most used for track entity instance. In order to explain all the possibilities that we have, we were thinking in a new case, a pretty actual new case, let's say, which is the COVID-19 contact, the recession and follow-up. So let's do an example with all the possibilities in this program. You can see it in your home screen in the Android application, so you will see a COVID-19 contact organization follow-up program. So for this, for the track entity instance, the coordinate could be where does the person list. Okay, so we are going to capture the coordinates where the person actually resets. For the enrollment is, for example, where did the person enter it in the program? Let's say the facility or the hospital where the person was detected by COVID-19. For the program stage or the event, we create one program stage called follow-up and the coordinate could be where is the person being followed with that, because imagine that you have been enrolled in a hospital but then you are followed about in a small facility or a different place than the hospital where you enter in the program. The data element, we have called it a first contact. It's related to where was the first contact, I mean, where did you get infected, let's say, or do you think that you get infected? Well, let's summarize before. That's it. That is more or less the different coordinates we are going to capture for this use case. In order to show you how can be different use and know, let's repeat. Track entity instance, where does the person lives, the enrollment, where did the person enter in the program? The program stage is going to be the follow-up, which is where you are being followed up and the data attribute, data element, sorry, is going to be the first contact. Where did you get infected or where was the first contact you think you might have with the COVID-19 positive? So let's go one by one for the track entity instance, which as you remember is where does the person lives. In the service, you have to go to maintain a track entity type and in the track entity type person, which is the track entity type for our program. You have to select in the feature type if you want point or polygon. Remember that the point is a single coordinate, the polygon is a set of coordinates, which define an area. So let's think in a point. So you will see in the Android application, you will see a field called coordinates for person, which is of type point, okay? So you see the latitude and the longitude. You will see three points. Starting for the left, the first one is related to select your current location. So if you tap on it, you will register a latitude and longitude with your current layout. The second one is the selection in a map. So you will move to another screen when in a map focused in your current location, where you can select a point. And the third one is the next, which is to clear the field. So this is the way you can register a coordinate for a track entity instance. Next one, enrollment. For the enrollment, if you remember, is where did the person enter in the program? We have to go in the server to maintain a track program, our COVID-19 program. In the enrollment details, you will see the feature type option. And again, you have to select if you want none or if you want to have a coordinate that we are doing in this use case, you can select point or point of. So you will see in the Android application, you will see in the register data coordinates for the enrollment, okay? So below, you will have the coordinates for you are going to enter where the person was registered. Okay, for program stage or events, which is, for example, where is the person being followed up? The same. You have to go to the server to maintain us. And in the tracker program, you will go to the program stage section. And then in the stage details, you have the feature type. And again, you select point or polygon or none. So in this case, you will see it in the application inside the program stage. So if you can see here on the right, you will see the follow up program stage and a field which is asking you the latitude and the longitude, okay? And again, you have the same option, the map, the coordinates, and the clear. For data elements or attributes, in this, in our use case, is going to be an attribute. Where was the first contact? Okay, so we are going to create a track entity attribute called first contact coordinates. And the value type is coordinate, okay? So for this, in the Android application, what you are going to see is a field called first contact coordinates and the same. You will have the opportunity to enter a single coordinate or select within a map. Okay, the org unit attribute, okay, is using the org unit instead of the coordinate to locate the patient. So for here, we have to create a track entity attribute and use the value type, the organization unit, okay? And then if you add the data to the program, you will see that you can set by organization unit your location. Okay, let's see how this information that we are capturing in the Android application is being visualized in the Android application as well. As I said before, the org unit is not supported for the Android application for visualization. So for track entity instance, well, first of all, let's see how we are seeing the coordinates in the map. So if you enter into the COVID-19 contract registration program, you will see by default a list of your track entity instance. And in the bottom, you can see two options. The one on the list that is selected, which is the list, and the second one is the map icon. If you tap on the map icon, what you are going to see is the same list of track entity instance, but position it in the map, okay? The position in the map is the coordinate that we entered for the track entity instance. And then you will see at the bottom of the map a carousel where you can swipe. The map is going to be centered in the different track entity instance you are selecting. So set that for the track entity instance, okay? We have the map layer, which is the icon on the top right when we will see. Then we have the current position. We have the option to navigate to the position. And then we have the carousel, okay? When you can navigate across the TAIs and the events. Okay. The map layer, the first button, the map layer has different options. And it's the way that you configure what you are seeing in the map, okay? So the first thing you will see is the option to see the map layer, the street view or the satellite view, okay? I think you are familiar with this because there is very common in all the map applications. Then you will see the option to show the TI, which is selected by default. This is the coordinate of the TI in the map. The second option is to show the enrollment coordinates in the map. If you remember, where does the person in our use case, where does the person enter in the program? The third option is the follow-up, which is our program stage that we call follow-up. And in our use case is where is the person being followed up, sorry. The fourth option is our data entry attribute, which is the track entity attribute, sorry, which is the first contact coordinate. And the fifth is the heat map layer. Okay. So the first option, if you select the first option is the satellite or street view. And by selecting this, you will see the map as a satellite. As I said before, it's pretty common. The second one is the attributes. So let's say, let's see that we selected the first coordinate attribute, first contact coordinates. What we are going to see in the map is the coordinates where the track entity instance was infected. No, the first time they have the contact with a positive. So we will see the map. Then, for example, for events, that in our case is the follow-up, we are going to see where are these person being followed up. So as you can see here, we have selected the take coordinates and the follow-up. So we are seeing, and these are the icons that are showing that the red circle is for the, for example, here in the Super Mario track entity instance, we are going to see that here. This is the place where the person lives. Here is the place where the person is being followed up. Okay. The same for the rest of track entity instance. Well, in the next session, we are going to see the relationships between the track entity instance in a map. Okay. I am going to show you the, I'm going to stop to share the screen and I'm going to show you. Andres, there is a question on the chat. What does heat map mean? Okay. I am sorry. I'm preparing the line. Yeah. So while Andres prepares this, I will answer your question. The heat map can be used. It's not very easy to see now. Maybe when Andres presents the the phone, we can see it, but basically is to know heat maps in the sense where do you have the, sorry, I'm going to put the camera. Where do you have the biggest number of occurrences there? Meaning that, for example, imagine you're tracking disease. And with the heat map, you can see where more points have been recorded. So basically when you zoom out, it allows you to see where more cases or more coordinates have been registered. As you see, Andres is doing it. So now it's a very, yeah, if you keep going, you will see that the heat map spreads. This is much better if, depending on the exercise Andres proposes, maybe tomorrow we can see, because when you have much, many more TIs, it's more clear because at one point this will become even reddish. So when you have a lot of points in the same nearby location, it becomes like glowing. I don't know how to, it's actually a heat map. That's the word. I don't know how to rephrase another language. Yeah, clustering or grouping cases are exactly morally. Thank you very much. Exactly. A hotspot. Yeah. Yeah, for this example, as we have only three tracking disease, it's not very clarified, but just tomorrow after the exercise, we can show how it looks like. Thank you, Jaime. So, well, I'm going to show you more or less what we have been talking about in order to later go for the exercise. So let's more or less start from the beginning. Okay, we have to see in our home screen the contact registration and follow-up program. If we enter, we will see the list of our track and street distance. And on the bottom right, we have the map icon. Okay. So if we go there, we're going to see our track and street distance selected in the map. And then we have in the map layer, we have this option. So, for example, let's say that, let's see where does the track and street are being followed up. So here in the map, we can see that the location appears. Okay, let's try to, for example, add also where this person was enrolling in the program. So we are going to see that they were enrolled in, were in different places, that case. And for example, where was the first contact? Okay. So yes, it looks like the first contact was in the same place. So it's like an indicator of contact, a contact point from COVID, for example, in this case. So if we go enter off a track and street instance, we're going to see in the details that we have the coordinates for the track and street instance, the coordinates for the enrollment, then in the attributes, we are going to see the first contact coordinates, which is here. And then in the follow-up program, if we go in in the details, which is the first option in the bottom bar, we are going to see the coordinates for the follow-up program stage. And in this way, in this way, we have all the way we can visualize and capture the coordinates for the Android application. Now, if you want, we can talk about the exercises. So we're going to have a little bit more time, but the session should be 15 minutes. What you should know by the end of the session is how to add coordinates in a track and street instance, how to visualize the GPS coordinates in the app, and how to use the different map layers. Okay, I didn't add a track and street instance, but for sure you know how to do it. You know we are here to help. And then I have just shown how to visualize the coordinates and how to use the map layers. Okay, so what you have to do is to enter three cases in your country or city with different locations, to don't see one or the other. The data entry on a shared program, which is the COVID-19 contact registration and follow-up, which you should see in your home screen in the app. You need to add a picture to the image attribute. You can take a photo or take it from the gallery. It doesn't have to be a person or whatever image you want. And in that way, we are going to be able to visualize the three track and street instance in the map. Okay, then you need to sync your cases with the server. For the submission, what you need to do is to take three descriptions of the map showing the three track and street instance card in the card user. So, for example, let's go here and let's remove the coordinates for the rest only track and street instance. So for example, you can do a screenshot here for Super Mario, a screenshot here for Sonic, and then another one here for Rock and Ray. Okay, and then one screenshot where all are visible, like for example this. Well, I think if you have any doubt, I'm going to be aware about the chat and the slide. I can keep showing the slide in order to see what you have to do. I'm going to share the slide. Okay, and that's it. We are here to help you. Thank you.
