THE ITOS/OCHA COD service update process

The process is

ABSOLUTELY FREE!

There is no financial cost for CO /RO

Getting baseline date ready to be used

CODS: 2 Tiers of Optional Services

1. Evaluate, document and create potential COD Candidates

Based on OCHA guidelines

CODs already registered on hrresponse.info or submitted directly to ITOS for evaluation

CODs are provided as live services

Multiple language support

Accepted candidate deployed as live services

Funding provided by

Virginia

Questions:

• Why this is recurrent in many emergencies?Is it really unavoidable?

• Why are we not maintaining up to date databases (or at least be aware of the limitations of the ones available)

• Is it worth investing on it during preparedness phase, even if we do not see the impact at first sight?

COD: The Common Operational Datasets (CODs) are critical datasets that are used to support the work of humanitarian actors across multiple sectors. They are considered a de facto standard for the humanitarian community and should represent the best-available datasets for each theme.

Separate Pcode

labelling service...

Base Map Services

Display and query for ESRI or OGC clients

ESRI Map, WMS, KML Image Overlay

Problems and detected bottlenecks:

• Cleaning datasets is a time consuming element that the current workload at RO/CO does not allow to do regularly

• Seems to be litle interest between partners to have COD ready to use: each partner usees its own available datasets....

• Governments and administrations do not want to share up to date datasets as information is considered strategic...

While those assumptions are correct, does not mean that the task will not have to be carried out .

In an emergency the task wil have to be accomplished in record time...

What does OCHA FIS propose to solve that issue?

Map services based on

Name labels, capitals, and geometry

Pcode Service

Pcode labels for all clients; feature extraction for OGC clients

ESRI Map, WMS, WFS, KML Network Link

ESRI Feature Service

The partner:

Institute of Government's Office of Information Technology Outreach Services , Better Known as ITOS

http://goo.gl/XsdfJR

Feature extraction for ESRI clients

Role:

• Provide technical service to review, evaluate and analyze the COD layers related to Administrative boundaries and Settlements.

• Inform the CO/RO of key findings to improve data quality.

• When possible, and under the supervision of the CO/RO, perform layer cleaning tasks

• Transform final layer into 12 different formats for user access (shape, GDB, Json...)

• Create online map services for data access

Solutions:

• OCHA has partnered with ITOS (University of Georgia) to work exclusively in the COD service update. The objective is to improve the quality and interoperability of these crucial CODs.

• ITOS will help improve the quality of the COD by reviewing the structure, quality and robustness of those datasets.

• ITOS will provide the technical desktop office work to refine the layers and help coming out with a final, clean, interoperable, sharable and up to date dataset. In other words, ITOS will do most of the time consuming job for you!

• ITOS will work side by side with your CO an established and OCHA approved process. CO/RO input, spatial intelligence and ground truth are key to the success of the project. The CO will be the custodian and owner of the final resulting COD layers developed by this collective effort

Common Issues

In Admin and Populated Places candidates that can be resolved

Same Name and PCode for Adjacent Admin Units

PCODES not fully constructed, or out of date

PCODES Not Consistent

COD Identification and layer selection

Under guidance from IMO,

ITOS evaluates CODs

Candidate delivered as file geodatabase

Creates report about issues found and fixed

Stakeholders and partners decide which datasets are CODs

Writes 19115 metadata

Creates additional table of admin levels

Mali

Jordan

Creates packages in 12 formats - suitable for HDX

Places fall outside

admin boundary

Inconsistent Spellings Among Data Layers

Topology Errors

Red and orange marks show gap and overlap errors

Multiple Points Representing One Populated Place

3 records with the same geometry.

They have unique p-codes and slightly different spellings but represent the same place. It needs to be one record with alternate spellings located in the Alternate Name fields

Inconsistent Geometries Among Data Layers

Topololgy: slivers,

gaps, nesting

STATUS Map

Services: Colombia, Mali, Burkina Faso, Iraq, Jordan, Syria

A recurrent problem:

Situation: Breaking news!

There has been a 7.8 earthquake in the country of Robertalia. Seems districts of Ara, Bera and Cira have been hard hit. Thousands gather on the streets , and some buildings have collapsed, general hospital at Ara has been destroyed...

So UN is starting to plan an emergency relief operation...

Conversations liker this follow in many agencies HQ and CO...

Managers office: Ok team...lets get there fast...give me all the COD and basic data about Robertalia...Do we know where those Ara, Bera and Cira districts are? Which cities are located there? How many people are living there? where is the nearest airport?

IM Team leader: here you are, Dataset we got are from 1999, when last earthquake occurred. But we have not updated it...you know it is hard to work with Robertalia statistical office and ourt IMO have been working in other tasks...

Managers office: I don't care. We must solve the situation. I want updated data..why we did not work on having clean datasets . Coordinate an IMWG and try to get the best data you can!

...meanwhile n the new, in hudnders of skypegroups., chats, irq..

IMO 1: I have found a dataset i downloaded from Google but have no clue of the source or the year it represents. DH, SBTF and HOT are working on reviewing all they can find on Robertalia with he volunter communities...They will come out with something soon...

IMO 2: A friend of mine shared with me this map of the country he was holding from the time he was here with an NGO, but it is from 2002 and administrative division have undergone revision....

IMO 3: UNHCR claims this admin dataset is the most up to date one, but is different from the one that OCHA is providing...partners are doubting which one is the one to use...Metadata is missing

IMO 4: whatever... I will use what I can find and report on my stuff and map all I need. We will later see how we solve that issue of layers in the IMWG (what a boring meeting we had last week...)my boss wants the maps out by next sitrep.

Does it sound familiar?
