The challenge
HCG's network data came from many places: as-built drawings, GPR and DGPS field surveys, laying contractors and door-to-door consumer surveys. Nothing brought it together on one map, and the requirements for the new system were strict.
- Serve six geographical areas from one system, with each GA selectable from the dashboard.
- Built on open source, with no licence or user-number restrictions, and the full source code handed over.
- Secure, controlled access in line with MeitY guidelines.
- Field teams who work on low bandwidth or with no signal at all.
- Hosted on HCG's own server, not a vendor cloud.
The solution
MapGeoid built an industry-standard CGD data model, migrated HCG's existing network data into it, and delivered a web GIS for the office with a companion Android app for the field. Both work on the same live database, so a change made in the field shows up on the office map as soon as it is approved.
The platform follows OGC and ISO open standards and reads and writes the formats a gas utility already uses, including SHP, KML, DWG, DXF, DGN, TIFF, ECW and Excel.
What we delivered
Each module was built to the requirements in HCG's project document.
Pipeline network GIS
Every asset layer (pipeline, valve, valve chamber, CGS, DRS, TLP, junction, service regulator) on Google, Bing, OpenStreetMap or satellite base maps. Steel, MDPE and service lines are colour-coded, with filters by district, GA and charge area.
Network analysis
Select any MDPE valve to see the exact area it feeds. Draw a circle anywhere to count the customers, valves, DRS, pipeline length and line damage inside it.
Dashboard
GA-wise progress, pipeline surveyed, O&M activity, inspections, line damage and patrolling, in weekly, monthly or quarterly charts. Charts export to PNG, JPEG, PDF or SVG, and the data to Excel or CSV.
Construction management
Planned and executed networks are shown on the same map in different colours. Laying contractors upload route surveys (SHP or KML), and HCG approves or rejects them, with a two-level check by the TPI and then the client.
Incident management
Field teams log incidents, cathodic protection readings, patrolling observations and line damage, with their location. Every incident is kept as history, so it can be filtered by year and type on the map.
Consumer search
Find any consumer by phone number, meter number, name or CRN, and see them on the map. Admins can correct a consumer's location, and as-built sketches and commissioning reports can be attached to an asset.
Android field app
Works offline and syncs when the signal returns, even on 3G. Field officers capture points, lines and polygons with admin-defined forms, update meter numbers, and connect DGPS receivers for accurate positions.
Security and user management
Each employee and stakeholder has their own login, with role-based access by officer level. Only admins can create or change users. Field data reaches the map only after an administrator approves it.
How we delivered it
Week 1
CGD data model designed, and existing network data migrated into it.
Weeks 2–10
Web GIS, dashboard and Android app built, then integrated module by module.
Go-live · March 2026
Deployed on HCG's server after user acceptance testing. Officials, field users and admins trained, and source code handed over.
Ongoing
Under an annual maintenance contract, with new features added as HCG asks for them.
The outcome
- One live map of the network across all six GAs, shared by the office and the field.
- Contractor and field data now passes through approval before it reaches the map.
- HCG owns the system outright. It runs on their server, with no licence fees and no user caps.
- Live in about ten weeks, and now under AMC.
