1 Best practices in the use of GIS & census mapping

2 Overview Ensuring Commitment for a long-term digital census mapping program Conducting a comprehensive needs assessment Tailor-made methodology of integration A Permanent unit for Cartography/GIS within the NSO Partnership and cooperation Capacity Building for sustaining the census mapping program

3 Ensuring Commitment for a long-term digital census mapping program Defined long-term funding plan including cost recovery and data pricing strategies Inclusion of accurate estimates for maintenance and associated costs Frequent milestones and delivery of output products to encourage adherence to pre-set time frames Use of clear protocols, for example with GPS for the collection and processing of data Adherence to geographic standards

4 Conducting a comprehensive needs assessment Completion of a user needs assessment and a priori definition of output products, with a clear implementation schedule 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.)?

5 Conducting a comprehensive needs assessment (cont.) Initial 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

6 Conducting a comprehensive needs assessment (cont.) Conduct an inventory of the census data requirements and sources of relational information. Widespread availability of digital data on the Internet, many GIS projects do not ensure efficient data collection, input, and integration. Check for data that are already in digital format. Examine the requirements for census data conversion (scan paper maps. input data from statistical yearbooks etc.)

7 Tailor-made methodology of integration Use of data integration methodologies; Well-established quality control /quality assurance procedures 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? Tailor-made methodology of the spatial analysis methodology 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

8 A Permanent unit for Cartography/GIS within the NSO The decision to invest in geospatial technology is needbased and problem-driven Cannot be technology-driven or as an independent add-on Technology is treated as an integral part of the overall management strategy Detailed strategic, operational and managerial planning based on a realistic assessment of costs and effort involved, with clear goals and objectives defined for geospatial operations

9 Partnership and cooperation; Solid development of cooperative agreements with other interested parties Fostering of spatial data infrastructure arrangements to expand partnerships and cooperation Facilitation of data sharing through detailed documentation and metadata across user networks

10 Capacity Building for sustaining the census mapping program A champion or key person(s) to promote geospatial development within the organization, and high-level management support In terms of human resources, ability to provide training and support for relevant employees and management Staffing needs met, including the ability to retain skilled staff and hire contractors where appropriate Well-defined written contracts with vendors, consultants, partners and clients within and outside the government
