1. A Spatially Referenced Point of a Dwelling Frame
Geography Division: Statistics South Africa 1

2. USES OF THE DWELLING FRAME
Sampling of dwelling units (DUs) per EA
FWU were created using the count of DUs
NB: Sampled DUs, Segment Boundaries and FWU are then loaded onto GoSurvey
Notes
Dwelling frame update in preparation for KwaZulu-Natal Citizen Satisfaction Survey 2015 and Community Survey 2016:
The frame consists of geo-coded points that have x;y coordinates.
This was mainly a desktop, office-based activity using Digital Globe very high-resolution imagery as backdrop.
A Silverlight geo-spatial interface was used for capture and QA, and the data stored in a centralised geo-database. ArcGIS technology was also utilised.
2. Usage in field operations and logistics:
A sample that was drawn for fieldworkers to visit dwellings of interest already had geo-coded points.
Fieldworker units were then created using ArcGIS application to enable work units created to be assigned to a fieldworker and a supervisor and used during field operations.
Topography and distance calculations were done using ArcGIS technology to guide field operations and logistics.
Sampled points, fieldworker units, imagery and a basemap of supplementary vector features were loaded onto mobile Lenovo/ Samsung devices.
GoSurvey field navigation tool based on ArcGIS technology was developed and deployed on mobile devices to enable fieldworkers to navigate to sampled points to conduct enumeration on CAPI. GoSurvey accessed the spatial database stored on the Cloud and Digital Globe online Imagery Services.
A monitoring platform was used to monitor progress on the sampled points visited and the status of the data collection activity.
3. Post-enumeration QA and Dissemination:
The same work flow and interfaces used during field operations will be used to evaluate and test methods and underlying data used for enumeration.
The of the of the underlying frame dwelling frame will also be assessed and the magnitude of its impact on the enumeration quantified.
Spatially-enabled statistical products will be packaged for dissemination using the digital analytics platform.

4. GoSurvey works offline by default
IMPORTANT FACTS
GoSurvey works offline by default
Work assignments are automatically sorted per distance (straight line) from your current position to a sampled point
Displays map overview of the entire FWU once logged in
Automated and real-time updates of field progress (outstanding/visited dwellings)
Keeps records of every navigational event (e.g points captured accuracy level)
Option to tick on/off supplementary layers or datasets you want visible on the FWU map

5. LOGGING INTO GOSURVEY
NB: Ensure that you always use your Field Worker Unit (FWU) Number to log into Go-Survey.
NB: One fieldworker=one FWU & one device

6. AUTOMATED DOWNLOADING PROCESS
NB: Ensure that all layers are extracted.
Once-off connecting and downloading FWU datasets from the Server.

7. VIEWING ASSIGNMENT LIST
Tap on the assignment and it will direct you to the map display mode with all sampled points and highlights the selected point.
Record the selected map reference number
Select navigate icon.
NB: The first assignment is the one closest to your current position in a straight line.

10. Attempting to access CAPI when you are above 50 metres far from the sampled MRN
Confirmation will be required

12. OPENING INTERVIEWER APP
Upon finding a sampled point, you must open the CAPI Interviewer on GO-SURVEY. Select “ok” and then select “unsuccessful”.
If you are more than 30 metres to a point you will get a pop-up message notifying you as such.
Note: the GO-SURVEY is independent from CAPI and you will have to switch between these applications from here.
