Golf course renovation projects fail — or overrun — for many of the same reasons. Architects and superintendents describe the same project differently. Contractors dig in the wrong area. The club committee approves a plan they didn't fully visualize until the earthwork started. Existing infrastructure — irrigation pipes, drainage lines — gets cut because nobody knew it was there.
GIS-based renovation mapping addresses all of this. By building a spatial map of both the existing conditions and the proposed changes, you create a single reference document that keeps every stakeholder aligned throughout the project.
What Renovation Mapping Involves
Renovation mapping has two phases:
1. Existing conditions documentation — accurate mapping of the current course features that will be affected by the project
2. Proposed change overlays — drawing the intended new features on a separate layer, positioned relative to the existing conditions
The combination of these two views — existing and proposed — is what makes renovation mapping so powerful. You can toggle between them, show them simultaneously with different colors, and share them with different audiences depending on what they need to see.
Phase 1: Document Existing Conditions
Before designing changes, map exactly what's there. For a renovation project, this typically includes:
Affected Features
Draw precise polygons and lines for all features within the renovation scope:
- Fairway boundaries
- Green complexes (including collar and approach)
- Bunker outlines and internal drainage
- Cart path segments
- Tee complexes
Underground Infrastructure
This is the most critical layer for any renovation. Map:
- Irrigation main lines and laterals within the work zone
- Irrigation head locations
- Drainage pipe routes
- Electrical conduits (pump station feed, lighting)
- Any utility easements
Knowing where pipes run before an excavator arrives can be the difference between a smooth project and a three-week delay while a broken main line is repaired.
Topography
Enable the elevation layer in Atlas and import LiDAR data if available. Understand the natural drainage direction across the renovation area — this should inform how new features are positioned.
Reference Photos and Notes
Use Atlas's annotation tools to drop point features with photo attachments at locations of concern: areas with known drainage issues, weakened cart path edges, or subsurface anomalies found in previous work.
Phase 2: Map Proposed Changes
Create a parallel set of layers for the proposed project:
Proposed - New Green Complex(polygon)Proposed - New Bunkers(polygon)Proposed - Removed Bunkers(polygon, styled in red)Proposed - Cart Path Changes(line)Proposed - New Tee Positions(polygon)
Style proposed layers distinctly from existing layers. Common conventions:
- New features: bright, solid-colored outlines
- Features being removed: dashed red outlines
- Modified features: amber or orange outlines
This makes it visually immediate which elements are changing.
Overlaying Proposed Changes on Existing Conditions
The most useful view is when you display both existing and proposed layers simultaneously. In Atlas, both are visible and you can control opacity to allow each to show through.
For committee presentations:
- Turn off irrelevant layers for a clean view
- Zoom to specific holes to show detail
- Cycle between "existing only" and "existing + proposed" views to illustrate change magnitude
This replaces the traditional approach of showing two separate PDF drawings — a before and after that the committee must mentally compare. A GIS map lets them see both together, spatially accurate, at any zoom level.
Communication: Who Sees What
Club Committee or Board
Share a view-only link showing proposed changes overlaid on the course satellite imagery. Add written notes about project rationale to each proposed feature. For members without GIS background, this visual context transforms abstract plans into something they can immediately understand.
Architect
Give the architect edit access to the proposed layers so they can adjust polygon shapes as the design develops. Version control in Atlas means you can return to any previous version if a change needs to be reconsidered.
Contractors
Create a contractor-specific view showing:
- Proposed change polygons (what to build)
- Existing infrastructure layers (what to avoid)
- Access routes to the work zone
- Staging area locations
Share a view-only link or PDF export. This is the most critical use of renovation mapping — giving contractors spatial context to avoid buried infrastructure.
Irrigation and Drainage Engineers
Share the underground infrastructure layer with renovation zone overlay. This gives engineers the spatial information they need to plan irrigation redesign within the renovation scope without a site visit for every design decision.
Tracking Progress During Construction
Once construction begins, use Atlas to track actual work against the plan:
- Create a
Construction - Completedlayer - As each feature is completed, draw or update the corresponding polygon to reflect the as-built condition
- Compare against proposed layers to identify any deviations from plan
This tracking map becomes the as-built record at the end of the project — ready to fold back into the permanent course GIS map.
Post-Renovation: Updating the Permanent Course Map
When the project is complete:
- Archive the original (pre-renovation) layers with a dated archive label
- Replace them with the new as-built polygons from your construction tracking layer
- Update irrigation and drainage layers to reflect any relocated infrastructure
- Add any new soil profiles, drainage specifications, or seed mix information as attributes on the new feature polygons
Your permanent course map now reflects current conditions, with a historical record of what was there before — a searchable record that will serve every future superintendent, architect, or contractor who works on that course.
The Most Common Renovation Mapping Mistakes
Skipping infrastructure documentation. The most expensive renovation mapping mistake is failing to map irrigation and drainage before excavation starts. Take two days to walk the work zone with a GPS, mark every head and drain inlet, and sketch pipe routes before anyone digs.
Using one layer for everything. Lumping existing and proposed features into the same layer makes it impossible to toggle views and creates confusion during the project.
Not sharing with all stakeholders. A renovation map kept only between the superintendent and architect doesn't solve the coordination problems that cause most project delays.
Renovation mapping is a small investment in time that pays back many times over in smoother project delivery and better stakeholder relationships. Atlas makes it achievable without specialist GIS software or contractor support.
