cleaner, faster data

"What CWEST can do for you"

Increased Data Accuracy

CWEST technology excels in both error prevention and the timely discovery and correction of the unforeseen:

CWEST eliminates four major sources of mistakes in surveys:

  • Rekeying errors—CWEST removes the whole rekeying process
  • Incorrect questions asked — CWEST automates questionnaire skipping patterns, ensuring the right questions get asked
  • Inconsistent responses—CWEST runs hundreds of consistency checks during entry to ensure that clean, consistent data are recorded. Click here to see how CWEST’s elaborate consistency checks are allowing the capture of precise consumption and poverty data in Tanzania.
  • Inaccurate positional and area data—CWEST automatically captures elaborate GIS data, ensuring accuracy. Having a UMPC communicate directly to the GPS (in-built or attached) allows for more detailed and more accurate GIS data:


  • Walking the circumference of a field to measure its area
  • Measuring altitude
  • Recording multiple GPS readings as data streams in
  • Qualifying the accuracy of each reading by logging the number of tracked satellites.

CWEST’s instant data access significantly improves the quality of data collection. Headquarters can closely monitor on-going field work, enabling instant feedback or intervention when necessary. While in traditional surveys many problems are highlighted only after a few months, CWEST allows survey managers to be on the ball from day one. As data flows in during pilot and early survey phases, the questions themselves can be improved and transmitted instantly to your teams in the field
