10. Data delivery and feedback

11. Some problems with paper... Collection + Centralisation + Capture + Transfer = A rather long time Inconsistency ≠ inconcistensie 36N0663880, 153548 = Where exactly?

12. Advantages of electronic data collection -Speed of delivery (fast turnover) -Potential for improved accuracy and consistency -Incorporation of GPS, media

13. Disadvantages of electronic data collection -Management and administration of forms -Need for some technical know-how and infrastructure -Tablets break, get borrowed, rained upon etc.

14. Managing forms....
