The benefits of GIS in large-scale urban development in Saudi Arabia
Large developments bring together planners, designers, contractors, utility companies and future operators, each with their own data. A geographic information system (GIS) puts that data on one map in one coordinate system, so decisions are made on the same picture.
IllustrationThe short answer
GIS gives a large development one shared, location-based source of truth: survey, drone, utility, design and asset data in a single coordinate system. It speeds up planning and approvals, prevents utility clashes, tracks progress across the site and carries a usable asset record into operation after handover.
Main benefits
- One source of truth: every party works from the same layers in the same coordinate system.
- Better planning: site selection, land use, access, environmental constraints and phasing analysed on one map.
- Fewer utility clashes: existing and planned utilities from surveys and GPR shown together before excavation.
- Progress tracking: drone surveys and site data compared over time across a large area.
- Faster coordination and approvals: maps and reports generated from current data rather than redrawn.
- A record for operation: assets handed over with location and attributes, ready for maintenance.
Where the data comes from
A project GIS is only as good as its inputs: control-based topographic and as-built surveys, drone orthophotos and elevation models, utility surveys with GPR and electromagnetic locators, and design and BIM models placed in real-world coordinates (Geo-BIM). Agreeing the coordinate system, the data standards and who updates which layer at the start of the project avoids most problems later.
How YAZ Development helps
YAZ Development provides GIS and geospatial mapping, drone surveying, GPR utility surveys and Geo-BIM integration in Saudi Arabia, so survey data arrives ready to use in a project GIS. YAZ carried out surveying and underground utility detection, including drone topographic surveys, in the early stages of NEOM.

Common questions
What is the difference between GIS and BIM?
BIM describes individual buildings and structures in detail; GIS describes many features across a large area in their geographic context. Geo-BIM places BIM models in real-world coordinates so the two work together.
Does a project need a GIS from the start?
It is most useful from the start, when site data is collected and coordinated, but it can be added later from existing surveys and drawings.
Which coordinate system should a Saudi project GIS use?
The one set by the project and the client, normally tied to the national reference frame KSA-GRF17; using a single system for all layers matters more than which one is chosen.

- How to set up survey control on large construction projects in Riyadh Establish a primary network of stable monuments, observed with static GNSS and tied to the Saudi national reference frame (KSA-GRF17), adjust it by least squares, then densify it with total station traverses and precise levelling close to the work areas.
- Construction surveying and setting-out for infrastructure projects in Saudi Arabia Construction surveying transfers the design onto the ground and checks the result: it covers control checks, setting-out of alignments and structures, levels, as-built surveys and survey records for quality control.
- How accurate is 3D laser scanning for construction, and how to choose a provider Modern terrestrial scanners measure single points to a few millimetres at short range, but project accuracy depends on registration, ties to survey control, range and surface.
- How structural monitoring keeps excavations safe on Saudi infrastructure projects Before digging starts, a baseline is measured on the retaining walls, the ground and nearby buildings.
- Scan to BIM vs a traditional measured survey: which one does your project need? A traditional measured survey records selected points and dimensions and suits simple spaces and small scopes.
- GPR utility detection before excavation: how it works and what to expect A utility survey starts with existing records, then sweeps the area with electromagnetic locators for metallic services and scans it with GPR in a grid to find metallic and non-metallic pipes, ducts and voids.
