Web GIS: from field to office without duplicate entry
How to connect mobile capture, PostGIS, and the office map in one production system.
Why split workflows cost money
When field and office use different tools, data lags and errors are copied manually. Web GIS keeps PostGIS as the single source of truth.
What to implement
Mobile-friendly forms, server-side validation, map layers, and user roles — one flow from capture to map review.
Production and maintenance
After launch you need hosting, security updates, and support. A SaaS model (setup + annual maintenance) covers that predictably.
