Survey Solutions

Marketing research companies, governments, and organisations all require information from surveys to support their decision-making processes. Such surveys require meaningful design and statistical weighting to ensure accurate execution and representative information for quality and unbiased results. An up-to-date database of the population demographic estimates, dwelling unit classification, and household counts is, therefore, key to successful research and survey projects.

GEOTERRAIMAGE has developed innovative and modern technological methodologies and algorithms to maintain this database (GTI Sampling Frame), which can be used as a foundation to design and prepare sample surveys.

Marketing research companies, governments, and organisations all require information from surveys to support their decision-making processes. Such surveys require careful design and statistical weighting to ensure accurate execution and representative information gathering. An up to date database of the population and dwelling units is therefore key to successful research, studies, and surveys.

GEOTERRAIMAGE has developed innovative and modern technological methodologies and algorithms to maintain this database, which can be used as a foundation to design and prepare sample surveys. This allows demographic estimates, and analysis of neighbourhood lifestyle and socio-economic indices, urban expansion, landscape changes, and urban characteristics, down to enumeration areas to assist in comprehensive planning and design of sample surveys.

Sampling Frame

The GTI Sampling Frame is key to successful research, studies, and surveys. It allows for the design, weighting, and analysis of surveys of all sizes (small localised to large national).

The GTI Sampling Frame provides a comprehensive set of key variables including the number of households, nighttime population, estimated daytime working population, demographics, Neighbourhood Lifestyle Index®© (NLI®©), and geographic type e.g. metro, urban, rural (farms and traditional).

The sampling frame also fills the voids of new urban expansion (New Developments and densification – e.g. vacant to golf estate) by keeping track of these changes and updating the population demographics associated with such change. These updates are released annually.

The GTI Sampling Frame can be used on any boundary (Enumeration Area, Sub Place/suburb, Municipal, etc., or any custom boundaries).

Demographics

To account for the dynamics of urban growth and the heterogeneous nature of society the researchers require current, comparable, and consistent demographic information. GEOTERRAIMAGE provides insights into the current demographic distribution per enumeration area (EA) in terms Age, Race, and Gender, as well as the dominant in each of these categories.

We provide fundamental demographic insights to support a better research project and conclusion while improving the quality of your survey for more accurate results.

Neighborhood Lifestyle Index®© (NLI®©)

Understanding your consumers is key to ensuring your products and services meet their needs. Through the Neighborhood Lifestyle Index®© (NLI®©) we provide various industries with the tools to not only identify, analyse and understand their target market or potential consumer base, but also to compare and analyse neighbourhoods, their competitors, or their existing sites.

GEOTERRAIMAGE Neighbourhood Lifestyle Index™© (NLI®©) is an income-based indicator that segments areas according to various lifestyle characteristics, providing researchers with the latest market segmentation at an enumeration area (EA) level.

The Neighbourhood Lifestyle Index™© (NLI®©) can be used as a profile/analysis tool for survey planning and design, as well as to analyse results for the different income groups (low to high-income classes).

Urban Dynamics- Building Census

By continuously identifying, mapping, and classifying individual building structures (Land Use) in South Africa, we provide the market research industry with a national inventory of almost every building, at a micro-level.

Our database consisting of 84+ unique building structure classification classes (with more than 18 residential classes) is continuously updated, providing key input for the annual updating of the GTI Sampling Frame. GEOTERRAIMAGE provides the cutting-edge factor, as sectors can keep track of urban, regional, and rural development, stagnation, and declines.

The availability of the building structure information in the sampling frame makes it possible to sample specific dwelling types (e.g informal structures) or non-residential types (e.g. commercial structures).

Advanced Population Dynamics

The GEOTERRAIMAGE day-time population information is designed to provide insight into the working and residual population in an area during the day, whereas the national census information (night-time population) is essentially a night-time survey, indicating where people reside.

This dataset indicates the influx and outflow of the working population indicating where people are during the day. This, together with the remainder component is useful information for survey planning and interviewing time scheduling.

Survey Sampler

GEOTERRAIMAGE provides users access to relevant, consistent, and comparable information through Survey Sampler™©, the innovative solution to manage their sampling process anytime, anywhere.

Survey Sampler, the revolutionary tool which is based on the GEOTERRAIMAGE building structure dataset, can be used to draw the dwelling and/or non-residential building structures for the interviewing process. The unique building structure points ensure precise sample locations for the specified dwelling and/or non-residential building structure types, by providing the latitude and longitude coordinates of each sampling unit, as well as a Land Use classification. Clear fieldwork maps, showing the area with the selected sampling points, are also produced.

Computer-assisted telephonic interview (CATI)

A database consisting of more than 16 million contact telephone numbers from the credit bureau is linked to the GTI sampling frame on an EA level. Using this combined database information, the best possible representative and the unbiased sample could be obtained, by designing the sample on the population totals of the GTI Sampling Frame, after which the respondents are randomly selected from the linked telephone database.

It is also possible to design a mixed CAPI (Computer-assisted personal interview) – CATI survey, for example, lower /middle-income CAPI and higher-income CATI.

Survey solutions for Africa

Africa is often troubled by the accessibility, relevancy, and recency of available data and data sources which emphasises the variety of challenges experienced by the market research industry. For a holistic view and across-the-board market advantages, the survey community requires reliant, comparable, quantifiable information to continue investing in research, investing in brands, and investing in Africa.

GEOTERRAIMAGE provides agile solutions to integrate, relevant information and knowledge for most African countries which allow for consistent, repeatable, and reliable data generation and solutions such as sampling.
