PlanSnapper vs EagleView: Two Different Tools for Two Different Problems
PlanSnapper and EagleView both appear in conversations about measuring property square footage — but they solve completely different problems. PlanSnapper measures interior GLA from a floor plan document. EagleView measures exterior footprint dimensions from aerial imagery. Understanding the difference matters before you choose one.
The core difference
EagleView captures aerial imagery of properties and derives exterior measurements from it — roof dimensions, footprint area, pitch. It is used heavily in insurance underwriting, roofing estimation, and exterior property assessment. Some appraisers use EagleView reports to confirm exterior dimensions when a property is not accessible.
PlanSnapper works from existing floor plan documents. You upload a floor plan PDF or image, trace the perimeter of above-grade living areas, set one known wall length to calibrate the scale, and get ANSI Z765-compliant GLA. It does not capture anything from satellite or aerial sources — it reads what is already on the page.
PlanSnapper vs EagleView: at a glance
| PlanSnapper | EagleView | |
|---|---|---|
| What it measures | Interior GLA from floor plan documents | Exterior footprint and roof from aerial imagery |
| Input source | Floor plan PDF or image you upload | Aerial/satellite imagery (they capture it) |
| Output | ANSI Z765-compliant GLA with area breakdown | Exterior dimensions, roof slope, footprint area |
| Measures interior GLA | Yes — trace any living area | No — exterior perimeter only |
| Works without site visit | Yes — if you have the floor plan | Yes — aerial data is already captured |
| Primary users | Appraisers, agents, investors with floor plans | Insurers, roofers, appraisers, contractors |
| Pricing model | $9/day or $29/mo subscription | Per-report pricing (varies by product) |
| ANSI compliance | Yes — built for ANSI Z765 | Not applicable (exterior perimeter, not GLA) |
When appraisers use EagleView
EagleView is useful for confirming exterior footprint dimensions — especially when a property is difficult to physically measure or when the appraiser wants to cross-check sketch measurements against an independent aerial source. It is also useful for confirming the presence or absence of additions that may not be reflected in public records.
However, EagleView's data is exterior. It does not distinguish between above-grade and below-grade living space, finished and unfinished areas, or garage versus habitable area. For ANSI-compliant GLA, appraisers still need to work from a floor plan or field measurements.
When appraisers use PlanSnapper
PlanSnapper is designed for the situation where you already have the floor plan — from the MLS, from a prior appraisal, from the builder, or from a scan app — and you need an ANSI-compliant GLA calculation from it. You trace the above-grade living areas, exclude attached garages and below-grade areas, calibrate with one known dimension, and get a calculation you can defend.
It is especially useful for desk reviews, retrospective appraisals, and any situation where you have a floor plan but are not physically at the property.
Can they be used together?
Yes — and for thorough desktop research they complement each other. EagleView can confirm the exterior footprint and identify any additions or structural changes not reflected in the existing floor plan. PlanSnapper can then calculate interior GLA from the floor plan, with EagleView's data used to validate the scale calibration or flag discrepancies.
Bottom line: They do not compete. If you need exterior dimensions from aerial imagery, EagleView does that. If you need ANSI-compliant GLA from a floor plan document, PlanSnapper does that. Most appraisers who use both are doing so because the two tools serve different parts of the workflow.
Have the floor plan? Get the GLA.
Upload any floor plan PDF or image, trace the perimeter, set one known wall length — and get ANSI Z765-compliant GLA in minutes.
