GIS Skills Essential for AEC Professionals & Digital Twin Projects

Geographic Information Systems (GIS) have revolutionized the way we analyze, plan, and manage territory. From urban planning to environmental protection, from public health to logistics, GIS is now a key technology for interpreting the world around us in a dynamic and intelligent way.

In the AEC (Architecture, Engineering, Construction) sector, GIS is no longer just a support tool, but a true strategic competence. Integrating geospatial data into design processes allows for the creation of intelligent digital models, improving operational efficiency and building Digital Twins capable of accurately representing the built environment.

If you are involved in design, engineering, or land management, knowing and mastering GIS skills is now essential. In this guide, you will discover which skills are truly indispensable today for working with GIS in a professional and integrated manner.

What are GIS skills and why are they fundamental today?

GIS skills (Geographic Information System) represent a true pillar for those working with territorial data, especially in technical and strategic sectors such as engineering, architecture, urban planning, and logistics. Knowing how to use a GIS no longer just means creating maps: it means analyzing, integrating, and interpreting geospatial data in an advanced way to support complex decisions, plan infrastructure, manage territory, and design sustainable scenarios. This is why these skills are increasingly in demand in the AEC field and beyond.

Among the practical applications in the AEC sectors of GIS skills, we find:

• integration between BIM models and territorial data for the creation of Digital Twin;
• design of georeferenced infrastructures and analysis of the surrounding environment;
• construction site management with support for safety and spatial logistics;
• monitoring of works over time with updated geospatial data;
• analysis of land use, environmental impact, and energy consumption;
• simulation of future scenarios for city management;
• urban mobility planning and traffic flow optimization;
• management of urban green spaces and public utility networks.

It is therefore evident that today GIS is much more than a mapping tool: it has become a central platform in digital projects, capable of connecting and harmonizing data from heterogeneous sources.

Those who master GIS skills today are able to tackle future challenges in a multidisciplinary way, leveraging data, space, and time as strategic assets. Let’s then see together which GIS skills technicians and designers must master.

Basic GIS skills for technicians and designers

With the continuous evolution of GIS and its growing centrality in decision-making processes at a global level, professionals equipped with the right GIS skills are increasingly in demand.

Among the main basic GIS skills are:

1. creation and sharing of cartography, with layers, models, locations, places;
2. working with maps and layers, managing content and metadata;
3. proficiency in GIS software, ArcGIS and QGIS offering, for example, intuitive map design features and extensive data manipulation capabilities;
4. computer programming, with Python or JavaScript for example, as this bridges the gap between traditional spatial analysis and the dynamic world of web GIS;
5. GIS modeling, creating digital representations of real-world objects or features, capturing their essential attributes and relationships;
6. development of analyses, with map overlays, unions, spatial statistical tools;
7. creation of graphic representations, starting from raw geospatial data. This is possible when a technician is able to filter complex datasets and transform them into clear and layered graphs, easily understandable by both GIS professionals and laypeople;
8. integration with other technologies such as BIM or web services, to ensure interoperability and a multidisciplinary vision in territorial and infrastructural projects.

Integration of BIM and GIS for Digital Twin: A New Frontier

The BIM-GIS integration certainly represents the future: the use of specific BIM GIS software allows the integration of GIS maps with 3D models, openBIM models, structured meshes, and point clouds, enabling the simultaneous management of a large amount of information from different disciplinary fields within a single scene.

Creating a digital twin of a city’s infrastructure with BIM software means enriching the geometric model of the work with the GIS data related to the territory where the infrastructure is located (weather information, seismic data, etc.).

This means that by having all the information available in GIS maps, BIM informational models can enhance environmental resources, energy savings, safety, and much more. Smarter planning, design, construction, management, and maintenance of infrastructure assets require the simplification of the flow of information between construction data and operational data, and this is made possible by BIM-GIS integration.

3D Technologies and Advanced Data Formats in GIS

GIS data is available in multiple forms and formats, which are generally used to store and transfer geospatial data and can be used as sources for layers in mapping projects.

GIS formats mainly differ into vector formats, which represent various data as geometric objects, raster formats, which instead represent data as an image, tabular formats, which collect data in tables, and specialized formats.

Among the main vector formats are:

1. Geodatabase (.gdb), the main format from Esri “Environmental System Research Institute”, for storing and managing GIS data. It is a format that efficiently manages large datasets, supports complex data models, relationships, and topologies, managing all various attributes in an advanced manner, but it is primarily designed for Esri products, making it difficult to share with non-Esri users;
2. Shapefile (.shp), developed by Esri, remains one of the most used formats due to its simplicity and compatibility. It indeed has a simple structure and is widely supported across all platforms, but it is limited in size (2 GB) and is always associated with multiple files (.shp, .shx, .dbf, etc.);
3. GeoJSON (.geojson, .json), an open standard format based on JavaScript Object Notation (JSON), particularly widespread for web mapping applications. It is well supported across all programming environments, but it is not ideal for working with large datasets;
4. KML/KMZ (.kml, .kmz), the “Keyhole Markup Language” and its compressed version KMZ were developed by Google Earth and are now widely supported across all platforms. Very suitable for 3D representations, but not ideal for analytical work.

Among the raster formats we remember:

• GeoTIFF (.tif, .tiff), the standard for raster data in GIS; it is nothing more than a TIFF that has embedded geographic information;
• ERDAS IMAGINE (.img), specialized for remote sensing data;
• JPEG 2000 (.jp2), very suitable for aerial and satellite images because despite the image compression, it ensures good quality;
• MrSID (.sid), ensures high compression rates while maintaining image quality.

Among the tabular formats instead:

• Comma-Separated Values (.csv), simple text files with values separated by commas, easy to create and modify in spreadsheet applications;
• Microsoft Excel (.xlsx, .xls), a widely used and supported business format;
• Database tables (SQL Server, Oracle, PostgreSQL), which allow enterprise-level data management and multi-user access.

Finally, specialized formats should also be mentioned such as:

• LiDAR Data (.las, .laz), point cloud data that provides information on 3D elevation;
• CAD Formats (.dwg, .dxf), which ensure direct interoperability with engineering projects;
• BIM, providing detailed 3D information about structures;
• ArcGIS Online/Portal Services, always updated services with shared resources;
• WMS/WMTS (Web Map Services), standards for map images.

IFC Models: Understanding the Basic Classes of the Industry and Their Role in GIS

Esri’s GIS products allow importing and interacting with IFC (Industry Foundation Classes) data, enabling users to provide geospatial analysis and visualizations in their construction and infrastructure projects.

This integration between GIS and openBIM offers significant advantages in planning, design, construction, and project management processes: by using IFC, an open and standardized BIM format, and importing it into ArcGIS for example, it is possible to use 3D data in cooperation, enhancing interdisciplinary collaboration and optimizing geospatial and urban planning work.

It is easy to understand how planners can enrich 3D urban models with BIM data, taking urban development to the highest level and beyond! All various infrastructure projects will improve: real geographic analysis allows for more informed decisions aimed at optimal management of the built environment even on a global level.

Point Clouds: Processing and Visualizing 3D Point Data

Point clouds are nothing more than a collection of spatial points represented as X, Y, and Z coordinates. The data can be used to define a usable 3D surface for various purposes, including mapping elements such as terrain, buildings, roads, and other features.

The integration of GIS maps with 3D models, openBIM models, structured meshes, and point clouds allows for simultaneous management of a large amount of information from different disciplinary fields within a single scene. This integration thus enables the creation of true smart cities, Geospatial Digital Twins, consisting of BIM models, IFC, point clouds, associated with GIS.

If you want to learn how to process and visualize 3D data with GIS platforms, I recommend reading the article “Integrating Point Clouds in GIS: A New Frontier for Spatial Analysis”.

Textured meshes: integrating detailed surface textures into GIS projects

3D textured meshes allow for the creation of photorealistic visualizations of territories and cities, and therefore of buildings and 3D spaces, providing an immersive experience and enabling stakeholders to better understand and visualize the environment, simplifying communication and collaboration on various projects.

3D textured meshes are used by designers to:

• create realistic and immersive visualizations of urban areas with buildings, roads, and other urban elements in the form of textured 3D meshes;
• perform inspections, measurements, and manage resources;
• manage emergencies and natural disasters by integrating geospatial data with real-time data. In a textured 3D mesh, it is possible to visualize affected areas, plan entry and exit, assess damage, and simulate emergency response scenarios;
• create digital twins based on meshes. The 3D mesh provides the shape, structure, and appearance of the object, allowing for realistic visualization and interaction within the digital twin environment.

The power of geospatial digital twins

A geospatial digital twin is a digital representation that faithfully mirrors a real environment, updated in real-time.
For the creation of a geospatial digital twin, GIS skills are essential because they provide, on one hand, the location data necessary to map a digital replica in the corresponding physical space, and on the other hand, real-time data that allow for simulating the changing conditions of the physical world.

In fact, geospatial digital twins are a powerful tool in urban and regional planning because:

• they accurately represent complex systems through reliable maps and spatial analyses based on geographic information systems (GIS) technology;
• they reflect changes over time, showing historical, current, and future states;
• they are scalable and adapt to changing needs and various built and natural systems;
• they enable more informed decision-making.

For example, in detailed urban planning, a geospatial digital twin can demonstrate how new buildings will affect traffic flow, street lighting, or water supply networks. Utilizing this technology allows for simulating different scenarios before undertaking concrete interventions, enabling more informed and sustainable decisions.

OpenBIM^® Standards: ensuring data interoperability and consistency

To ensure data interoperability and consistency and to prevent changes to an openBIM model from having a direct impact on GIS, it is extremely important to use platforms for managing geospatial digital twins.

These platforms indeed allow:

• the real-time updating of geometric and informative data on the GIS map, optimizing project management and making collaboration between engineers, architects, and surveyors more efficient. This way, one works with synchronized, always real information;
• interoperability, through the use of open and non-proprietary formats that can be opened and shared across multiple software platforms, optimizing collaboration.

Improving GIS skills with specialized software

As previously mentioned, to improve GIS skills, it is important to use specific software capable of quickly and efficiently visualizing geographic context data, enhancing site understanding and analysis.
