Online Virtual Tour Builder: PanoPublish Browser-Based 360 Editor

An online virtual tour builder is a browser-based software tool that allows photographers and agencies to upload 360° panoramic photos, connect them into a navigable walkthrough, add interactive elements (hotspots, floor plans, nadir branding), and publish the finished tour to a shareable link or directly to Google Maps — without installing any desktop applications.

Key features to evaluate when choosing an online virtual tour builder:

1. Google Maps Integration: Can the tool publish directly to Google Street View via OAuth2? Or does it require a separate manual upload step?
2. Nadir Logo Branding: Does it handle nadir disk overlays in the browser, or do you need Photoshop?
3. Floor Plan Integration: Can users navigate via a 2D floor plan map with clickable room pins?
4. Client Review Workspaces: Can you share a private review link with clients before publishing?
5. INR Billing: Is the subscription billed in Indian Rupees with UPI support, avoiding forex markups?
6. Mobile Preview: Can clients view the finished tour on mobile without installing an app?
7. White-Label Hosting: Can you remove the platform's branding from client share links?

Step 1 — Prepare Your 360 Photos: Export equirectangular JPEG files from your 360 camera app (Ricoh Theta app, Insta360 Studio, or GoPro Player). Ensure each file is under 50MB and has GPS and compass heading (PoseHeadingDegrees) embedded in EXIF metadata.

Step 2 — Create a Project: Log in to PanoPublish. Click 'New Project' and name it by client and location.

Step 3 — Upload Panoramas: Drag your equirectangular JPEG files into the upload zone. PanoPublish's EXIF parser automatically reads GPS coordinates and compass headings. Photos without GPS can be manually pinned on the integrated map editor.

Step 4 — Configure the Node Graph: In the visual node editor, panoramas appear as circles on a map grid. Draw connections between adjacent nodes by clicking and dragging. Set the display arrow direction for each connection to match the visual geometry of the space.

Step 5 — Apply Nadir Logo Overlay: Upload your client's logo (512x512px transparent PNG). PanoPublish composites the logo disk automatically over the tripod footprint at the bottom nadir zone of every panorama in the project.

Step 6 — Upload Floor Plan: Upload a PNG or PDF floor plan. Place panorama pins on the floor plan at the correct room positions. Visitors can click pins to jump to any room in the tour.

Step 7 — Publish to Google Maps: Connect your Google account via OAuth2. Select the client's Google Business Place. Click Publish. PanoPublish submits the full sequence to Google's Street View API. The tour appears on Google Maps within 24–48 hours.
