Ready, Set, Collect!

In the previous post we looked at creating data, publishing feature services on ArcGIS Online for Organisations and setting up two web maps with different access levels.
Now that we have two web maps – one for the general public and the one that allows authorised users to edit features, we can switch to the last phase of the workflow and use the Collector for ArcGIS application to edit the features.
If you don’t have the Collector for ArcGIS app installed on your smartphone, you can download it from the appropriate application store. The URLs are available here: http://www.esri.com/software/arcgis/arcgisonline/apps/collector
Once you’ve installed the app, run it and sign in to ArcGIS Online.
The maps that you’ve published will appear in the MyMaps list.
Hit More> next to the map that you want to open and press Open in the menu that will appear.
The default functionality of the Collector for ArcGIS app allows you to digitize points, lines and polygons using the GPS data captured by the smartphone. If you press the “location button” the application will display your current location
To capture a new feature you can use the Collect button.
Then choose a template to collect the new feature. Note that all the layers that are editable will appear as editing templates.
I will collect a new checkpoint (just like I was doing on our field trip in WA)
The system will allow me to fill out the attributes.
As I have enabled attachments, I can use my smartphone’s camera to take a picture.
I can select a photo from the library or I can take a new one
Hit Done when ready and hit Submit to send the information back to ArcGIS Online
Note the icon in the top-right corner which shows the accuracy
You can set the required accuracy in the Settings dialog.
This allows you to control the accuracy of your in field data collection.
Once you’ve hit the Submit Button, the users of the public map will see the new point with attributes and attachments showing in the web application.
As you can see this point is located in Brisbane, as I’m obviously writing this blog in Brisbane.
The points that the users collect in the field can later be exported to a shapefile or a CSV file.
Alternatively you can reference this feature service in a map document in ArcMap or another web mapping application either in AGOL or running from your ArcGIS for Server.
Frankly speaking, it took a lot more time to write this blog than to roll-out the entire solution in ArcMap and ArcGIS Online for Organisations. AGOL and Collector for ArcGIS app provide you with an easy and relatively inexpensive way to create a solution which incorporates centralized data storage and the field data collection techniques, summed up with a fast and easy way to disseminate this information to the public. This can be extremely useful in many applications, such as Emergency Response, environmental management and many others. Or you can just have fun with web and mobile GIS and let the World know whereabouts while you’re travelling.
Collecting your GIS data in the field just became simpler!
