Loaded projects show the recorded points on the map view.  you can scroll and zoom the map to explore the recorded data.

The project is waiting for you to add data.

Position yourself in the location where you would like to a add new point and press the green point arrow.   A new pin will be added to the map at your current location.

The data is added to the project and automatically saved.

Position yourself at the next location and press the green arrow to record a second point.

Repeat the process untill you have added all the points you need.  

If you would also like a photograph of the location you can press the green camera button.  This will open the camera and let you compose and take a photograph.  As you click the shutter, GPSnaps will also record the location and add a 'photo' pin to the map.   The data is recorded and saved as before, The photograph will be saved to a project folder and a link to the photo is recorded with the data.

To record points automatically as you pace out a survey,  set the timer to the desired interval, and press the start timer button that will appear.   Points will be recorded as before but at regular intervals.   Click the camera button at any time to pause the timer and take a photo,  the timer will resume once the photo is taken. click the red timer button to stop the interval recording.

Click the green Edit & Export button to view a list of the data points in the current project. 

Each line in the table is a single data point and shows the linked photo if one is present.  The points can be swiped to the left to delete them.  but be aware that once deleted they cannot be recovered.

The data can also be exported at this time.  The data will be collated into a CSV ( comma seperated values) file and can be sent to the iCloud or as an email attachment to any email address you choose.

Photographs will have been saved in Albums, with the name of the project, into your photo library,  and can be accessed in the normal way.

One possible way to utilise the data may be to upload the CSV into a GIS system such as QGIS and  to plot it as layered information over the relevant mapping.  It is also possible to use the links in the data to connect the photographs and view them interactively within the GIS layers.
