Summary

• Presentation and Dissemination of Results
• Evaluate the needs list for Census Mapping

Project goals related to the Census
Selection of a Methodology
Census Data and Map Inventory
Analysis and Accuracy assessment of the Census
Mapping Procedure
Presentation and Dissemination of Results
Evaluate the needs list for Census Mapping
activities to be conducted (according to the
previous evaluation above)
Redesign and re-evaluation of these suggestions
and procedures at various stages of the census
will help avoid hours of unnecessary work and
redundant tasks the next time census mapping
activities are carried out.

Project goals related to the Census

• What is the purpose of the census in relation to
  spatial analysis?
• What is the spatial extent (total area) and grain
  size (ground resolution) currently and what is
  preferred?
• Identify the information needs for census
  mapping What type of spatial data do you need to
  achieve your goals?
• What are the sources of these data, and what are
  the appropriate types of data to enhance census
  mapping activities?

5
Selection of a Methodology

• Constructing a logical spatial analysis flow
  chart that details the project steps will make
  the success of the census more likely.
• What types of collection (enumeration process),
  processing (pre post enumeration) and analyses
  (data dissemination) is needed and what will be
  performed?
• The spatial analysis flow diagram should include
• An outline of the procedures required for the
  collection of data and integration of
  possible existing data
• A logical sequence of census mapping procedures
  to be performed
• A list of all the existing data needed data
  required for each step

6
Census Data and Map Inventory

• Conduct an inventory of the census data
  requirements and sources of relational
  information.
• Widespread availability of digital data on the
  Internet, many GIS projects does not ensure
  efficient data collection, input, and
  integration.
• Check for data are already in digital format.
• What are the requirements for census data
  conversion (scan paper maps. input data from
  statistical yearbooks etc.)

7
Analysis and Accuracy assessment of the Census
Mapping Procedure

• Make the initial census mapping methodology as
  flexible as possible.
• There is often a need to revise the procedures
  originally intended.
• Consider that once the census mapping is complete
  or executed in the field, you should evaluate the
  accuracy and validity of the results which may
  require more fieldwork.

8
Presentation and Dissemination of Results

• Evaluate the results that have to be presented
• What formats best suit the audience (poster-sized
  map in electronic or paper form, journal,
  PowerPoint presentation, etc.)
• Are any advanced analysis of the results needed?
  (Overlays, Multivariate regressions, Spatial
  interpolations)

9
Evaluate the needs list for Census Mapping
activities to be conducted

• What are the costs for Upgrades of hardware
  or/and existing software?
• Is a LAN configuration needed?
• What are the staff training needs/ Is the
  existing workforce adequate?
• What is the ease and difficulty as far as
  installation of hardware/software as well as
  maintenance?
• What infrastructure documentation, manuals,
  Help-line, and vendor support (patches etc.)?

10
Issues to be considered in system selection

• Cost
• Upgrades
• LAN configuration
• Training needs/Workforce
• Ease of installation
• Maintenance
• Documentation and manuals
• Help-line and vendor support
• Means of making patches for support
• Complex and Confusing Process Savvy GIS consumer
  should research, select, test, and question
  systems before a purchase is made.

• Redesign and re-evaluation of these suggestions
  and procedures at various stages of the census
  will help avoid hours of unnecessary work and
  redundant tasks the next time census mapping
  activities are carried out.
