-Click on any cell of your choice and you will see a similar screen to the graphic on your right. The square selected will have a cyan frame around it and a window on the bottom part of the screen with the words This cell is available. This is the current attribute associated to that square.
-Click on the edit button on the bottom left corner (Android) or upper right corner (iOS). Depending on your device it will be a pen or a square with an arrow, as indicated in the graphics below: Â
Go back to the map and take a look at the square you just updated. It should have turned red and if you click on the details box at the bottom of your screen, the new window should display your full name as recorded information.Â
It may happen than some squares may be edited at the same time and only the last edit will remain. Do not worry if this happens with your square. The idea is that you get to practice conditions similar to a real-wold scenario. Try again a different square and make sure to click update to send your edits to the cloud.
Creating new features in a Collector Web Map: Trees
The Trees dataset has been designed in a way that all collaborators can create, update, and delete new features. To create your first tree, zoom into your square that you have selected.
Click the + sign in the middle top (iOS) or bottom (Android) section of your screen. This will allow you to create a new feature. Since the only layer in our map that has that permission is the Tree layer, this is the only one available for editing in your screen.
If you are indoors, a new screen warning you of Poor Location Accuracy appears. Click Settings and move the required accuracy to 100m and click OK.
- Select whether the tree is Deciduous or Evergreen. Once selected, another screen will appear with other attributes.
- ForÂ
Type, leave your initial selection (Deciduous or Evergreen) unless you made a mistake, in which case update it, click Done or press Enter.
- For Species, type the name of the species you think it is (does not need to be accurate - you are the experts!). Click Done or press Enter.
- Enter the Diameter for your tree at chest height in cm and enter it.
- Select a Condition describing the overall health of the tree: Good or Poor. Click Done or press Enter.
-Enter any relevant Notes. For example, if the tree is in poor condition, describe what is wrong.
- Under Mapped by, type your Full Name.
Click the photo (iOS) or the attachment (Android) icon (depending on the device) at the top/bottom of the screen to take a photo of your tree. A new  window appears:
- If you have an iphone, press the camera icon at the top of your screen, click Add under attachments and select Take Photo or Video.
- If you have an Android device, click the Clip+ at the bottom of your screen. Select Camera in the Add attachment from window.
Click Use Photo or the Checkmark at the bottom right of your screen. This will attach the photo toÂ
the tree location and attributes. Click Done (for iphones).
- If you are using an Android tablet, a new window appears asking you to validate the location. Click Go to map. The program will take y
- If you are using an iphone, click the map icon at the top center on your screen. ou back to the map where you can drag the location of the tree to the exact place you want it.
When you are done, click Submit (on iphones) or Done (on Android, may also be a checkmark). This will send updates and post the attachments to the collective map.Â
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.
When you click on your added new tree, notice the pop-up window has the attachment, but the photo is not visible. You can change this later on the map view in ArcGIS.com, selecting Configure pop-up and making sure linked attributes are visible.
Viewing the Results in ArcGIS Online
Now that you all have mapped out the trees in the field, let's take a quick look at the resulting map in ArcGIS Online. You will first log in to the site and then visit the Group page for this exercise, where you can access the web map directly.
-Open a browser and navigate to www.arcgis.com.
-In the upper right, click on Sign In.
-Click the button to Sign in with ENTERPRISE ACCOUNT.
-Type clemson in the box and click Continue.
-Click to sign in USING YOUR CLEMSON UNIVERSITY ACCOUNT.
-Sign in with your Clemson username and password.
-On the main page that opens, click on Groups on the top. In the list of groups, click on FOR 4340-6340. On the next page, you should see several items that are shared with the group.
-Under the Field Data Collection with Collector map, click on the Open button beneath the thumbnail and select Open in map viewer.
The web map now opens in the browser. Take a minute to familiarize yourself with the layout. If you know ArcMap already, the interface will be a bit different but should be easy to learn to use!
-Try turning off the Fishnet layer to see the trees better.
-Click on a tree to see the pop-up. This is configured to show the attributes associated with each point. You can also open the attachments (photos) for the trees by clicking on the link in the popup.
Notice the default symbology, which uses the TREE_TYPE field to symbolize the trees as either evergreen or deciduous. Let's do a brief exploration of symbology in ArcGIS Online to visualize the tree diameter.
-In the Content pane, hover the cursor over the Trees layer and click on Change Style (the geometric shapes).
-Notice the default (Type of tree) is selected, and is drawing using Types (Unique Symbols).
-Click the box under Choose an attribute to show and change to Diameter (cm).
-Click the Options button on Counts and Amounts (size).Â
-In the customization panel, click on the Symbol. Change the fill to a green color and click OK.
Notice that there are lots of options for classifying, how many classes, transparency, symbol sizes, visible range, etc., just as in ArcMap.
-Click OK and Done to accept the changes. View the result in the map.
Saving a copy of the Web Map for data collection on the field
You will save a copy of the web map that you could use as a starting point for collecting data in the field.
-At the top of the window, click Save and Save as.Â
-Enter a unique title for the map.
-Add a few tags for your map.
-Update the summary to describe what it contains and/or is used for. This helps you manage your maps.
-Change the Save in Folder to the folder with your username (the default). This will store a private copy of the map, i.e. it will not be visible to the rest of the group.
