Geolocation Orchestration · High priority
- The Flask API must query three geolocation endpoints, merge the responses, and return a normalized location object that downstream users can trust.
- Support a single request that fans out to three external geolocation providers in parallel or controlled sequence.
- Normalize fields such as latitude, longitude, formatted address, confidence score, and provider source.
- Apply response ranking logic to choose the best result based on confidence, completeness, and latency.
- Expose error states when one or more providers time out, return invalid payloads, or disagree materially.
- Cache recent successful lookups to reduce repeated external calls and improve response times.
Hosted Postgres Data Layer · High priority
- The platform must persist user records, project/site location data, provider responses, and audit history in a hosted Postgres database.
- Store canonical location records, raw provider payloads, and transformation history separately for traceability.
- Use relational tables for projects, locations, users, jobs, cron runs, and event logs.
- Support indexing on address, parcel identifier, project ID, and updated_at for fast lookups.
- Maintain migration strategy for schema evolution as location fields expand.
- Enforce row-level access rules or tenant scoping to isolate customer data.
Daily Cron Job Automation · High priority
- A scheduled daily job must refresh location data, identify mismatches, and generate operational flags without manual intervention.
- Run a daily cron job that revalidates active records and checks for stale or missing geolocation data.
- Log each run with success/failure counts, duration, and affected records.
- Queue retries for transient provider errors and mark persistent failures for review.
- Generate alerts for large variance between providers or sudden address normalization changes.
- Support configurable schedules by customer segment or environment.
API Security and Reliability · Medium priority
- The API should be secure, observable, and resilient enough for production use in construction and prop tech workflows.
- Authenticate API requests using API keys, OAuth, or signed tokens depending on client type.
- Rate limit incoming requests to protect external endpoint usage and database resources.
- Add structured logging and tracing for each geolocation request and cron execution.
- Return clear HTTP status codes and actionable error messages for client applications.
- Provide health check endpoints for the Flask service and database connectivity.
Admin and Reporting Tools · Medium priority
- The product should include lightweight operational views for users and internal teams to understand data quality and system behavior.
- Dashboard for job status, provider latency, and endpoint failure rates.
- Report on geolocation match confidence, stale records, and unresolved addresses.
- Exportable CSV or JSON for downstream analytics and audit requirements.
- Filter by customer, project, status, date range, and provider source.
- Basic role-based permissions for admins, operators, and read-only users.
How users start using the app
- A user signs in through a secure web app or accesses the Flask API through an integration.
- They create or import a project/site record with an address, parcel ID, or location hint.
- The system immediately sends the location to the three geolocation endpoints and displays the normalized result.
- If confidence is low or providers disagree, the app prompts the user to review or correct the address.
- Within minutes, the user has an enriched location record and the daily cron job begins keeping it current.
1. Submit location data
- The user enters an address, site name, or parcel identifier through the UI or API.
- Validate required fields and show inline errors for incomplete or malformed addresses.
- Support paste-from-spreadsheet import for batch workflows.
- Return a request ID immediately for tracking.
2. Call geolocation providers
- The Flask API queries three external geolocation endpoints and captures each raw response.
- Use timeouts and retries for each provider.
- Preserve raw payloads for debugging and auditability.
- Measure provider response time and failure state.
3. Normalize and compare results
- The system converts provider responses into a standard location schema and compares them.
- Calculate confidence based on agreement, precision, and field completeness.
- Highlight mismatches such as different coordinates or city/postal code discrepancies.
- Choose a primary result and keep alternates available for review.
4. Persist and surface the result
- The app stores the canonical record in hosted Postgres and presents it to the user.
- Save the cleaned record, provider metadata, and confidence score.
- Render a summary card with map coordinates, formatted address, and source breakdown.
- Provide a clear CTA to accept, edit, or flag the result.
5. Automate ongoing refresh
- A daily cron job rechecks active records and flags changes or stale entries.
- Run on a predictable schedule with observable logs.
- Send notifications for low-confidence or changed records.
- Let admins suppress or pause refreshes for archived projects.
Advanced Features & Edge Cases
- Bulk geolocation enrichment for large project imports.
- Fallback handling when one or more geolocation endpoints are unavailable.
- User-controlled confidence thresholds to decide when manual review is required.
- Audit history showing all changes to coordinates and formatted addresses.
- Privacy controls for hiding precise location details from lower-privilege users.
- Manual override workflow for disputed or exceptional site records.
UI/UX Highlights
- Clean, map-forward layout with an obvious primary location summary and secondary provider comparison panel.
- Color-coded confidence and data quality indicators to help users spot issues quickly.
- Accessible forms with keyboard navigation, high-contrast states, and screen-reader labels.
- Fast perceived performance through loading skeletons and incremental provider result rendering.
- Mobile-responsive design for field operations and on-site verification.
Maya is a project coordinator juggling dozens of construction sites across three states. Before this product, she spent hours copying addresses into multiple mapping tools, comparing results, and chasing down project managers when a site record looked wrong. Every mismatch introduced risk: delayed permits, misrouted deliveries, and avoidable back-and-forth with operations.
With this platform, Maya enters a site address once and sees three geolocation sources reconciled into a single trustworthy record. The system flags a few edge cases automatically, while the daily cron job keeps active projects fresh without extra work from her team. Maya saves time, her managers trust the data more, and the company gains a scalable location-intelligence workflow that turns messy site information into a repeatable operational advantage.
