Geographic information systems (GIS) are incredibly broad and complex, with numerous applications for a wide range of industries. Most GIS functions depend on robust spatial data. This data represents the position of objects in space and how they relate to each other and their surroundings (as well as certain non-geographical data). Spatial data in GIS projects also helps with planning and analysis.

Doing so effectively further requires keen use of spatial data visualisation techniques. Like many graphical AEC and land-planning purposes, large format printing is an indispensable means of presenting spatial data and making GIS plans more engaging.

What Is Spatial Data in GIS?

Spatial data, broadly, refers to any information that directly relates to a geometrical space or, most commonly, geographical areas. There are many types of spatial data in GIS, ranging from simple geographic coordinates to elaborate, photo-realistic modelling and aerial photography.

While mapping is one of the main applications, spatial data can also relate to functions as broad as:

• Analysing geographical patterns
• Correlating geographical data with historical, weather, and other contextual data
• Remote sensing objects for spatial analysis (as with the "Internet of Things")
• Transportation and logistics

Advances in spatial data mining and visualisation software have dramatically expanded sources for GIS data. Modern spatial data structures in GIS must often consolidate an extremely broad range of geospatial, temporal, graphical, and other information. These data points come from maps, drones, satellites, signalling devices, weather stations, and much more,

All these functions share an ongoing need to consolidate and present such data in the clearest, most vivid, and most precise way. The breadth involved also underlines the importance of accommodating the widest possible range of spatial data in GIS large format printing.

Understanding Different Spatial Data Types and Structures in GIS

What Is Spatial Data Visualisation, and Why Is it Important?

Spatial data visualisation is any graphical depiction of spatial data in GIS applications. Options include maps, travel and logistics, and any correlating data (to cite just several examples out of an almost infinite amount). Some spatial data visualisation methods are application-specific, such as real-time traffic reporting. But others are more generic and accommodate a wider range of spatial data types.

How Large Format Printing Contributes to Spatial Data Visualisation

The vast majority of work that goes into interpreting spatial data structures in GIS must eventually be distilled into an accurate graphical representation. As sophisticated as digital GIS visualisations have become, numerous spatial data applications depend on large format prints.

Large format printing makes it much easier to exchange and reference GIS data, free of technological barriers or clunky screen navigation. Because spatial data types in GIS vary widely, it's important that your large format printer effectively displays:

• Geospatial coordinates and other raster data points with pinpoint precision
• Circular arcs and vector lines with the absolute least possible amount of "pixelation"
• Ultra-high-resolution satellite and aerial photography
• Maximum accuracy between RGB and CMYK colour formats to translate screen graphics to hard-copy visualisations

Is Large Format Printing the Best Way to Visualise Spatial Data in GIS?

Large format printing is one of two main formats for visualising spatial data. The other is, most broadly, digital displays. This, in turn, includes many other methods like fixed images, auto-updating records, and interactive graphical models.

No one visualisation method is "the best" except within the context of each particular purpose. It's far better to determine which type of spatial data visualisation is most suitable for a given application.

That said, large format printing is generally preferred when the spatial data is finalised and the technicians and/or stakeholders require a tangible and consistent point of reference. Physical prints also create a more professional image. Sensitive data is much easier to secure with physical copies than digital files (especially on networks).

Three Keystone Benefits of Using Large Format Printing for Spatial Data

Large format printing is one of the most effective ways to improve data visualisation, communication, and decision-making among GIS professionals and their industry partners. Higher-quality prints not only improve accuracy and planning but directly translate to higher KPIs and accelerated growth.
