In this activity you will be going out in the field to collect geographic data using Collector for ArcGIS application. You will be using LabQuest device to read Light intensity value for specific location and then recording the value in the Collector app. LabQuest is the most powerful, connected, and versatile data-collection device available for STEM education. It is standalone interface used to collect sensor data. Collector is a free app that allows you to collect or update your geospatial data with any iOS or Android device directly into your ArcGIS Online account. It allows you to log your current location, and put the data you capture to work so you can make more informed and timely decisions. It allows you to use maps anywhere to ground-truth your data, make observations, and respond to events. You'll be able to improve the efficiency of your field workforce and the accuracy of your GIS.  Advantages - Option for offline data collection - Multiple editors- User roles: update only, create, delete, and sync. - Geospatial design: domains, types, and subtypes - Participatory mapping with just a browser. - Collection of points, lines, and polygons. Tracking mode. App Requirements  - Free trial or organizational account of ArcGIS Online - Free download from App store (iOS) or Play Store (Androids): Collector for ArcGIS. Accessing your ArcGIS Online account in your device On your mobile device, open the Collector for ArcGIS application and log in to www.arcgis.com, click Continue. Sign in with the username and password that was provided to you at the beginning of this session. 1. Choose your location 2. Reading Light Intensity Data using LabQuest - Plug the light sensor into the LabQuest on the left side - Turn on the LabQuest (power button is in the top left corner) - Go outside to your specific location - Point the light sensor towards the sun (cord on the other end) - Record the illumination value displayed on the LabQuest Once, you have got the light intensity value, follow step next steps to record the value on the collector  application. 3. Recording data on your collector app You will see a map that has been shared with you. Tap once the Data Collection Exercise to open it. Do not click Download. This web map contains a dataset named as Light Data. Light Intensity Data The Light Data dataset has been designed in a way that all collaborators can create, update, and delete new features. To add your first point, zoom into the area . - Click the + sign in the middle top section of your screen.  - Choose Light Data as this will allow you to create a new feature. If you are indoors, a new screen warning you of Poor Location Accuracy appears. Click Settings and move the              required accuracy to 20 m and Click OK. . - For What is the light absorption in units of lux?, Enter a value (the value should be in between 0 and 25000). Click Done or press Enter A new window appears asking you to validate the location. Click Go to map. The program will take you back to the map where you can drag the location of the point to the exact place you want it. When you are done, click  Done on your tablets. This will send updates and post the attachments to the collective map. Updates can take a little bit of time to post, depending on your wireless connection. Make sure your edits are saved after each data point collected. To ensure that your latest update gets posted, close Collector and open it again. Navigate to your map and look for your edit. |
