NOMAD Pilot 2 - IOM Haiti
Transcript of NOMAD Pilot 2 - IOM Haiti
Phase 1 Identified important objectives for pilot Phase 2. Objectives Nov 2011 MEDES - Toulouse, France IOM Haiti IOM Haiti NOMAD Pilot 2 Phase 2 March 2012 1. Pre-deployment Configure a portable server and Imogene forms prior to deployment. 2. Mobile GPS Capture GPS points using mobile devices 3. Data Transfer Transfer data from the field using the EDGE Network 4. Polygon Forms Record the GPS boundary of a DTM camp using Imogene 5. Synchronization Send data captured via Imogene to existing IOM reporting Mar 2012 Configured portable Imogene server in controlled environment prior to deployment
Including Imogene spatial extension with GIS apps

GeoServer Web Mapping Application IOM - Port-au-Prince, Haiti 2. Objective Mar 2012 © IOM 2010 Pre-deployment in stable environement Configured Android GPS configuration to point to regional NTP servers
Mobile device GPS points (± 5m) compared to Garmin handheld GPS points (± 3m) Capture GPS coordinates using mobile device Network Time Protocol Stratum 1 Stratum 2 Stratum 3 north-america.pool.ntp.org Regional NTP servers points to the satellites that are within the region, resulting in a position fix within a shorter time frame FasterFix *Requires SuperUser permissions The NTP is a protocol and software implementation for synchronizing the clocks of computer systems over data networks In GPS, NTP is used to assist location by calculating an time offset from the GPS signal with the local time at the given location IOM - Port-au-Prince, Haiti 3. Objective Digicel WEB Access Point Name (APN) implemented with success Data transfer using EDGE mobile network Mar 2012 http://www.pool.ntp.org/en/ Enhanced Data Rates for GSM Evolution (EDGE)
Improvement for 2.5G GSM/GPRS
Supports mobile internet connections EDGE Network WAP Wireless Application Protocol
WAP gateways not based on HTTP (WP-HTTP, WML Script, etc.) Unsuccessful Transfer! WEB Standard HTTP requests Success! Name: digicel_ha

PostGIS functions implemented to process GPS points into polygon Record GPS boundary of a camp IOM - Port-au-Prince, Haiti 5. Objective Implemented Talend to create transfer of data from Imogene to IOM SQL Server Synchronize Imogene with existing reporting Results The follwoing phones captured GPS without configuration Blackberry Samsung Galaxy Note The following phones failed to capture GPS reliably with configuration LG P690 Motorola Motodefy iPhone 3G HTC Desire Name: digicel_ha

Using the ST_Collect function in PostGIS, the series of points are aggregated into a single geometry s1 s1 p9 p10 p2 p1 p4 p3 p5 p7 p6 p8 s1 DTM Polygon Using the ST_ConcaveHull function in PostGIS, the aggregated geometry of the GPS points is converted into a concave polygon PostGIS 2.0 Available for download, PostGIS 2.0 implements a new function, ST_ConvexHull Mar 2012 Talend is a powerful open source middleware solution providing cross platform data integration and management Talend PostgreSQL SQL Server 2005 Talend successfully created a link to transfer data captured using Imogene to existing IOM database and reporting infrastructure Talend ODBC Reporting NOMAD is a consortium supported by the French space agency (CNES) that includes iMMAP, CartONG, WFP, MEDES, Auvea, ACAPS, IOM and MobileActive.org.
The NOMAD consortium provide expert advice on the implementation of integrated digital data collection & communication systems for rapid humanitarian assessment & monitoring. Since the inception of the consortium, two pilots have taken place as a test bed based on active operations; WFP Ethiopia and IOM Haiti. This Prezi explores the technical details of the second pilot, IOM Haiti Outcomes Outcomes Samsung is the most suitable Android device for the capture of GPS points The EDGE network is sufficient to transmit data that includes images and videos from the field Imogene is capable of capturing point and polygon features derived from a series of location coordinates Imogene models using location can implement very simple forms, with associated data derived at the database from the captured location (i.e. administrative regions) Transmission of Imogene captured PostgreSQL data into existing organisation server infrastructure has been confirmed Imogene can suit the needs of IOM Haiti and is production ready software Further investigation and confirmation is required to determine the reliable capture of GPS position using mobile devices If you are interested to learn more about how your organizations existing data capture requirements and infrastructure could be enhanced with digital data collection systems, feel free to contact Christophe Bois at iMMAP (firstname.lastname@example.org) and Sandra Sudhoff at CartONG (email@example.com)
NOMAD visit http://humanitarian-nomad.org/ Go Digital A special thankyou to CNES, Medes, CartONG and IOM Haiti for the support that now can be used to benefit humanitarian operations everywhere around the world - and of course the participating partners in the NOMAD consortium Project supported by the French space agency Thankyou This prezi was prepared by iMMAP for the NOMAD workshop 2012
