Using Mobile data collection IDP Needs Assessment Survey in Serbia Using Mobile data collection Introduction Practical implementation

Mobile data collection sytem Data collection component Prediction algorithms Prediction algorithms Reporting GIS Data Collection Data Collection Data Central users Information System Epidefender Introduction

Mobile data collection sytem “Mobile data entry” vs “Paper forms” Time savings - eliminate the need for secondary data entry step Speed of transmission, Increased accuracy of data – no errors of omission Richer data (pictures, GPS) Built in business logic Limits: Initial training, Provision of phones Possible provision of airtime, Management of data capturers Resolution of system problems Stolen or lost handheld computers/devices Introduction

Mobile data collection sytem Typical Functionalities  Typed form fields (Text, Date, integer, numeric …)  Field validation  Field conditional visibility  Data filtering  Internationalized user interfaces Introduction

Mobile data collection sytem 5/9 First generation of mobile data collection sytem Conversion of paper form into electronic form ->DATA COLLECTION and DATA ENTRY in a single phase Data are stored as XML (example : “Open Data Kit”) Limits of the 1 st Generation: No possibility to search No possibility to update No visualisation of what has been collected More a “data filling” system than a “data entry” system Introduction

Mobile data collection sytem Portable information System The “2 nd generation” mobile data collection application: Data are stored in a local database (Example Epidefender)  Offline/Online mode  Bidirectionnal data synchronization  Manual or automatic data synchronization  Remote installation and update  Create/Read/Update/Delete/Search forms  User privileges management  Alert sending  Photo/Video/Sound acquisition  Geographical coordinates acquisition  Barcode acquisition/search  Form/Wizard mode Introduction

Mobile data collection sytem 7/9 Next step 1: Forms configuration The desing of the form may have to be adapted Skip logic, data validation process, Prefilled fields, Infobox Practical implementation

Mobile data collection sytem 8/9 Next step 2: Infrastructure set up Looking at prices and availibility, choosing the data transfer system : Use of 3G plus a server on the web Use of Wifi plus a local server on a LAN Looking at requirement, choosing the type of system : Simple data collection (1 st Generation) Portable information system (2 nd Generation) Practical implementation

Mobile data collection sytem 9/9 Next step 3: training & equipment Confirm the number of surveyors Train/Test the knowledge of surveyor for Mobile OS Procure enough devices Plan for external battery Practical implementation
