Comparison

Looking for a OnePlan alternative?

Site-planning software does what it says: it plans. Accurate drawings, tidy layouts, a polished deliverable — and a plan that freezes the moment gates open.

MasterGrid was built for what happens next. The geo-referenced map isn’t the deliverable — it’s the live database your event runs on: power loads, incidents, equipment custody, staff posts, and carbon, from load-in through load-out. If you’re sizing up OnePlan, here’s where the line sits.

OnePlan is GIS site-planning software — drawings and digital twins for the planning phase. MasterGrid is the operating system for the event itself: live power, NIMS/ICS incident command, equipment custody, and carbon accounting on the same geo-referenced map.

Where OnePlan stops

  • Scope is the planning phase: drawings, digital twins, and stakeholder presentations.
  • The plan is the deliverable — show-day operations live in other systems, or in radios and spreadsheets.
  • Power, incidents, equipment, and carbon aren’t objects the platform operates on.

Where MasterGrid takes over

  • The same map that planned the site runs the show — power, incidents, equipment, staff, and vendors in one live system.
  • Power is engineering, not a shape on a map: distribution design, live load monitoring, generators, fuel.
  • Incident command is NIMS/ICS-aligned with an evidence chain and automated reports for insurers and authorities.
  • Fuel and carbon reports come from measured operational data — no post-event archaeology.

Common questions

What is the main difference between OnePlan and MasterGrid?

OnePlan is GIS site-planning software — it produces accurate drawings and digital twins for the planning phase. MasterGrid is an event operations platform: you geo-reference your CAD once, and the same map then runs live operations — power loads, NIMS/ICS incidents, equipment custody, staff posts, and carbon accounting — through the show.

Can MasterGrid import the CAD plans I already have?

Yes. MasterGrid georeferences DWG, DXF and PDF site plans from any CAD — AutoCAD and Vectorworks export DWG — plus drone scans and Nearmap imagery, onto a live operational map with layer and opacity control.

Does MasterGrid replace OnePlan?

For operations teams, generally yes — MasterGrid covers geo-referenced site planning and then keeps going into live operations. If you specifically need 3D digital-twin deliverables for the planning phase, you can run a planning tool alongside MasterGrid.

How do I get MasterGrid?

Request a demo at mastergrid.io. We walk you through the platform on your own site plan and set up the license that fits.
