Topcon offers five primary office software options designed around distinct workflows in survey processing, CAD production, modeling and construction takeoff:
- Topcon Tools is a lightweight desktop tool for GNSS and total station processing, QA/QC, adjustments, localization, visualization, and reporting. It is often used as a preprocessing step before Topcon Office or other CAD workflows.
- Topcon Office Base is the core desktop environment for import/export, data prep, basic QA/QC, reporting, and light drafting. It is the foundation product for adding Survey and or Site Prep modules.
- Topcon Office Base + Survey adds survey-grade computation, adjustments, GNSS processing, richer COGO, drafting, and professional survey delivery workflows.
- Topcon Office Base + Site Prep adds modeling and construction takeoff capabilities for surfaces and corridors, volumes, and file prep tools for GPS-guided machine control systems.
- Topcon Office Base + Survey + Site Prep is the complete office suite that unifies survey computation and adjustment, drafting, surface and corridor modeling, quantities and volumes, and machine-control data prep.
Side by side selection guide
This overview highlights how each office product aligns with different responsibilities. Many organizations start with Office Base then add Survey and or Site Prep as their needs expand. :contentReference[oaicite:0]{index=0}

How to choose the right office software
- Select Topcon Tools when you need survey processing, QA/QC, least-squares adjustment, localization, and reporting without CAD production, modeling, or takeoff
- Select Topcon Office Base when you need a core office hub for import/export, coordinate setup, cleanup, reports, and light drafting
- Select Office Base + Survey when your office delivers survey-grade computation including control, traverse, GNSS processing, adjustments, and robust COGO deliverables
- Select Office Base + Site Prep when your focus is surfaces, corridors, volumes, takeoffs, and machine control data prep
- Select Office Base + Survey + Site Prep when your team needs the complete suite for survey delivery plus modeling, takeoff, design, and machine control workflows
