The Bahamas Experience

Preparation for Census 2010

Field Procedure

The Bahamas Experience

To update Enumeration District Maps on the island of New Providence and Grand Bahama (orthoimagery available) To update ED boundaries on other densely populated Family Islands (no imagery available) To Update Road/Street shapefiles

Objectives:

Preparation for Census 2010 Field Exercise

New Providence & Family Islands (Abaco, Eleuthera, Exuma & Bimini)

Teams of 3 – 4 persons consisting of :

1. A driver 2. A mapper 3. A counter 4. Assist with counting and splitting of ED’s while in the

field Verify Building counts of each ED area (100 household) Verify Street names Check ED areas of new development between 2007 - 2010 that may need to be subdivided

This exercise was conducted during the period of 2008-2009

Utilized Technology >Grand Bahama Project<

Pre Census 2010 GIS Unit conducted a field GPS mapping exercise:- Field Workers were placed in teams of two (2) per ED’s GPS handhelds were used to get a location and description of all buildings All new roads, footpaths were digitized Data was transferred from GPS units using Trimble GPS Pathfinder Office Data was exported as ESRI shapefiles format and imported to ArcMap Road /Street files were updated where necessary Delineation of new Ed areas for Census 2010

The success of matching census data (using Record of Visit) with Building Points layer

GRAND BAHAMA SUPERVISORY DISTRICTS 2010

Utilized Technology <New Providence Project>

Post Census:- Field mapping The GIS unit began the GPS mapping exercise on New Providence island in 2012. Presently: Team of 3-4 persons using GPS handhelds to capture building locations Road /Street files are being updated in field/office

Completion date Summer 2014

New Providence Island

<New Providence Project> Supervisory District

Mt. Moriah

Strengths and Limitations Strengths • Mapping skills improved • Faster method of updating shapefiles • Able to produce quality maps • Production of user friendly visual results • Income generating Limitations • Standardization •No permanent Supervisory District Boundary Cuts •Proper Address System •Equipment malfunctions • Shortage of field workers • Expense (travel to other islands) • Transportation shortage (Grand Bahama Project) • Imagery Outdated • Expert Assistant

Long Term Progress Post-Enumeration

Create Permanent Boundaries Lines •Completion of GPS mapping project Build a Census database (join census data to maps) Invest in technology (Google earth Pro etc), Expert Assistant

Post-Enumeration Data Analysis

• Analysis of the results with Desktop GIS • Development of maps for dissemination to the public
