Motivation
Household GPS MapHuge benefit to teams
Opportunity emerged in training
Household GPS Map
Listing preparation and survey are two people
Head of households sometimes misidentified
Usability
More context needed in base map
Basic GPS operations and procedures need more training
Power cables and mounts not reliable
GPS Capacity at CSO
gpx2shp
Convert GPS data into ESRI Shapefile in one automated step
GPS Capacity at CSOgpsbabel + mkgmap
Create GPS base maps from spreadsheet data
