1. SESSION 9 PLANNING AND IMPLEMENTING A CENSUS GEOSPATIAL PROGRAMME
FOR RWANDA 2022 HPC
as presented
By Jimmy MUKASA
Director of ICT NISR
During UN Regional Workshop on the 2020 World Programme on Population and Housing Censuses: International Standards and Contemporary Technologies at Dar-es-Salaam, Republic of Tanzania from 29 May to 1 June 2017

2. EVALUATING WHAT WE HAVE FROM THE PREVIOUS CENSUS PRE-ENUMERATION EXERCISE
For the 2012 Population and Housing Census, the census mapping carried during a period of one year provided:
A full DB of administrative boundaries, form the lowest level (village)
An approximate number of HHs based on estimation by village elders
Point infrastructure and important land marks coordinates to guide enumerators
Enumeration area were then delineated according to administrative units (village) and the estimate number of household within a village.
A village could be divided into one or more EA depending on its estimated number of households

3. GETTING BETTER LAND IMAGERY
Use of High resolution images:
High resolution images are crucial to guide enumerators along their enumeration area. They will be used to:
Create dot houses to every roof that can be seen on the image.
Database of Dot houses will be used:
To determine he approximate number of dwelling units by administrative unit (village)
Creating a high resolution density maps to help in the classification of urban/rural
B. As a background for each EA map to be given to every enumerator

4. PLANNING FOR THE ACQUISITION OF IMAGERY
Nowadays, satellite images are available via subscription services on cloud hosted platforms and accessed via web or end user software. EX: Digital globe
Easy to set specs, 4 months procurement time, immediate delivery, 3 years subscription, budget per country size
Portion of Kigali city with a 50 cm resolution image from Digital Globe cloud service

5. PLANNING FOR GIS SOFTWARE AND HARDWARE
GIS software (Office)
The most challenge about GIS software is the cost. However, nowadays some are free like QGIS. For some simple tasks like digitizing houses qGIS is just enough.
Some complex task can be run with ArcGIS software and we need as much licenses for office work as we have number of GIS staff

6. PLANNING FOR GIS SOFTWARE AND HARDWARE
GIS software (field)
There are many application for mapping, some are free and others not. The most important features are:
Capacity to collect point, line and polygon
Syncing with a remote server
Custom form for collecting attribute
Collecting and storing GPS metadata (like accuracy and time)
Reading offline base maps (PDF or any other format)
Some app today have some of the features, like collector for ArcGIS with Survey123, Avenza Maps we used for EICV5 that help enumerators to read EA maps on mobile devices.

7. USE OF THE TOOLS Determination of EA
The sense of EAs is to have small geographic units which are homogenous in term of the number of household to enumerate during the census and clear boundaries.
From a set of digitized houses from Satellite images, GIS software creates algorithms which look along existing points and allocate neighboring ones to an individual group. The algorithms creates a new Group Unique ID and attaches it to each single point. The user determine how big the group must be (ex 100 houses)

9. BUDGETING, STAFFING AND LOCAL PARTNERSHIP
Previous census mapping budget = about 1.75 Million USD = 9% of total Census budget
We expect it to reduce
Five Permanent staff
Four Temporary staff
Eight Paid Interns
