Data science has been a game-changing technology for industries ranging from marketing to healthcare. Among the various categories of data science, spatial data science has been steadily gaining global importance.

In this article, we will explore spatial data science, its definition, workings, importance, and tools while also briefly discussing the career prospects of a spatial data scientist. Further, we will discuss the importance of selecting high-quality data science training to help you progress in this field.

What Does Spatial Data Science Mean?

Spatial data science refers to the subset of data science that deals with data related to distance, location, and spatial interactions. It goes beyond ‘how’ things happen and delves into ‘where’ and ‘why’ they occur. It provides information about the effect of the location on a particular parameter.

For example, data science will use the data of a crop produced over time to predict crop production for the next year. Spatial data science will add the crop’s locational data and the location’s weather to make a much more accurate prediction.

How is Spatial Data Science Useful?

Businesses attempting to expand their global reach need information about the target areas and demographics. They must customize their brand and products to appeal to the target audience, and spatial data science is tremendously useful in this process.

For instance, data science takes the sales figures and analyses the pattern to predict future sales. Spatial data science takes the sales figures, assesses them based on the location and demographics, and predicts the variation for each location, providing a more accurate prediction.

Further, spatial data science is also useful when businesses deal with products that analyze locational information, such as soil conditions, weather and rainfall, groundwater levels, etc. In short, spatial data analysis can analyze anything that changes with location.

Spatial Analysis vs. Spatial Data Science

Usually, analysis and data science go hand in hand. However, there are key distinctions between spatial analysis and spatial data science. Let’s examine some of them.

Spatial analysis assesses data for patterns, trends, clusters, and hotspots. Spatial data science uses analysis to predict multiple parameters.
The spatial analysis uses site selection and location allocation to optimize the locations used in the study. Spatial data science extrapolates this data to find a pattern to identify other similar locations.
Spatial analysis utilizes exploratory techniques to find the interactions between multiple variables. Spatial data science uses machine learning techniques to feed the results and extract more information about the interactions apart from the known variables.

How Does Spatial Data Science Work?

While the use of spatial data science may vary according to industry requirements, the same steps can be applied in every case. Here are the major steps involved in its operation.

Step 1: Collect the data

Gathering reliable data from reliable sources is essential for sound analysis and prediction. The data are typically obtained from surveys, GPS devices, government databases, remote-sensing equipment, crowd-sourcing, and historical and current documents.

Step 2: Clean and process the data

The data may be available in multiple formats and contain errors, duplications, or omissions. Hence, it must be preprocessed and cleaned to convert it into a usable format. Geographic coordinates are assigned to the data points using georeferencing and geocoding.

Step 3: Store the data

Appropriate storage of the data is critical to prevent loss or tampering. Storage, such as geographic information systems (GIS), must be compatible with the data format and have superb capabilities to manage, organize, and retrieve the data.

Step 4: Analyze the data

Determine the parameters that will give you the information you need from the data. Treat the data to spatial analysis. Choose the appropriate technique for the analysis. The typical methods include interpolation, queries, machine learning, regression, and network analysis. The choice of the method is crucial as it impacts the accuracy and reliability of the results.

Step 5: Use visualization tools

Visualization is the core of spatial data science. Use efficient tools to display your results in graphs, heat maps, distribution maps, and charts. The color scheme and format must be comprehensible. Add interactive elements to include more than one type of information on the same map.

Step 6: Use the results

Ascertain the credibility of the results and use them to make critical decisions. The parameters must set a standard for the project at hand so that any future data can be analyzed and compared to these parameters. The results also give tangible form to the massive amount of data and make it simple for the decision-makers and other stakeholders to understand the scenario.

Step 7: Devise models for predictions

Assess the data for typical trends and patterns and devise models for them. The models should extrapolate the information and give estimations for the future. They must be able to predict the trends and provide approximate parameters.

Step 8: Evaluate and redo

Certain data may be available, or circumstances may change that contradict the models. Hence, it is always a good idea to be flexible and reassess the data for modification. New technologies can be used to reprocess the data and arrive at a new, more accurate model.

Step 9: Report your findings

Visualization allows you to view the data lucidly. However, communicating the main points is equally crucial, as not everybody can understand the maps or charts. Hence, report the key findings and inferences of your analysis in detail. Concentrate on describing the significance of the model so that the rest of the parties can immediately grasp its applicability. Point out the need, inferences, and actionable items.

Applications and Use Cases of Spatial Data

Most decision-makers in today’s competitive business landscape adopt a data-driven approach to finalize projects. Numerical evidence adds to the feasibility and credibility of a project. Hence, spatial data science has found application in multiple instances, such as:

Environmental conservation and natural resource management
Monitoring of deforestation, ecosystems, and wildlife habitats
Planning transportation systems and city infrastructure
Planning roads, routes, highways, and railways
Manage supply chain logistics vis-a-vis route, destination, and time
Analysis of climate changes, weather forecasts, soil conditions, and water
Manage health resources, medical accessibility, analysis of disease occurrences, and predictions of medical requirements
Analyze historical natural disasters, their impact, and their level of preparedness to predict and plan for the future
Track agricultural variation and productivity and manage irrigation, fertilizer usage, crop planning, and reaping times

Let us go through some use cases that better explain the applications.

Planning for a Metro Train Route

The metro train has become an essential feature in most metropolitan cities. However, as most cities have grown without a plan, selecting the route and managing the permissions and construction require detailed information about the areas.

Spatial data science collects data about the population and location of streetlights, traffic signals, flyovers, shops, and houses. It analyses the data and provides the most convenient route for the metro based on the maximum requirement, easy construction with minimal traffic disruption, accessibility, and sufficient space for the infrastructure.

Site Selection for Government Health Centers

Government health centers typically target the underprivileged population who do not have affordable access to healthcare. Spatial data science helps in noting such areas, mapping the most common diseases and outbreaks, the demographics, and the presence of essential utilities. It then provides the best areas that can cater to multiple areas nearby and have the necessary testing and treatment facilities. The size and capabilities of the health centers can also be decided based on the health concerns of particular areas, such as a diabetes testing laboratory for areas with more obesity and glucose issues.

A well-structured data science program equips you with a solid knowledge of spatial data science and opens your mind to innovative applications.
