Piloting and Documentation of Innovative Employment of GPS units in MICS4 Surveys in ESA Region Countries Mikel Maron GroundTruth Initiative OpenStreetMap
2
Let's figure out the cool stuff we can do with GPS in the survey
3
Current use of GPS in MICS Collect single point in center of cluster
4
OpenStreetMap Global Collaborative Mapping “kinda like Wikipedia for Maps”
6

7
Before After In OSM
9
Uses Immediate recovery Ongoing reconstruction

Kibera 1 million people(?), 2.5 km2 was a blank spot on the map

The Map!

DURING Base Map Cluster Location
21
DURING Track Collection
22
DURING Point Collection
23
Collection Forms
24
What cool stuff did we do with GPS in the survey
25
Tracks 8 GPS 1 trkpt per second 2+ months > 10 million trkpt
26
One GPS, Mbabane
27
Revealing Tracks
28
New Minor Roads
29
Repetition == Accuracy
30
Track Animation Week 1
31
Points of Interest No substantial collection Demanding Survey Supervisors Busy Optional Activity
32
Points of Interest Lessons Find right people (Measurers?) Require & Cost (Time, People, Geography) Motivation
33
Household GPS Map Huge benefit to teams Opportunity emerged in training
34
Household GPS Map Listing preparation and survey are two people Head of households sometimes misidentified
35
Usability More context needed in base map Basic GPS operations and procedures need more training Power cables and mounts not reliable
36
GPS Capacity at CSO gpx2shp Convert GPS data into ESRI Shapefile in one automated step
37
GPS Capacity at CSO gpsbabel + mkgmap Create GPS base maps from spreadsheet data
38
What cool stuff do we do next with GPS in the survey
39
Final Collection Tracks, Waypoints, Forms following conclusion of survey
40
Editing Tracks Into Base Map 15-20 million Trackpoints Every road in The country
41
MICS Spatial Analysis Correlation of Proximity of services to indicators Nearby schools : enrollment Nearby hospitals : health
42
Track Analysis & Applications Distances per vehicle, date, time of day Speed variability Distribution of movement
43
Data Sharing? CSO / Ministries Service Level Data Sets
44
Data Collection? Focused POI collection in reusable way Neighborhood Care Centres
45
