Points of InterestLessons

Require & Cost(Time, People, Geography)

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
