Features ShippedAll prioritized requirements metModernizing infrastructure planning at a national scale.
The Local Government Engineering Department is Bangladesh's largest government engineering agency. Despite maintaining a 10+ GB GIS database, LGED lacked an interactive web platform for dynamic planning-its maps were static, siloed, and disconnected from the central attribute database.
StreamsTech's partner, Jantrik Technologies Ltd., delivered a comprehensive GIS web application for LGED's ICT Unit in just 3.5 months, on budget and to specification. It became LGED's first interactive web GIS platform, enabling engineers nationwide to access dynamic maps and planning tools directly from their browsers without desktop GIS software.
Project Fact Sheet
What LGED needed to overcome
Before this project, LGED's GIS capabilities were largely siloed in static, pre-rendered maps and disconnected desktop tools. Field engineers and planners had no way to interact with the data dynamically.
Static, Uncustomizable Maps
Existing maps were pre-rendered in fixed portrait/landscape layouts. Engineers could not add or remove layers, change symbology, or generate project-specific views without manual effort.
No Database–Map Linkage
The road network GIS shapefiles were entirely disconnected from LGED's central Microsoft Access attribute database. Fetching road details required cross-referencing separate systems manually.
Duplicate Road Risks in Planning
Without a spatial cross-check mechanism, new project proposals frequently contained roads already assigned to other projects or under maintenance - leading to budget waste and duplication.
No Remote Access for Field Engineers
Upazila-level engineers had no self-service tool. Generating a custom district map required sending requests to LGED headquarters, causing delays in local planning and monitoring activities.
Incorrect Coordinate System
All existing GIS shapefiles used Lambert Conformal Conic (LCC) projection, which was incompatible with web mapping standards. A full reprojection to WGS 1984 was required before deployment.
Large Data Volume & Performance
The road network database alone exceeded 10 GB. Delivering interactive, responsive map rendering at this scale on the web required a carefully architected server stack and map engine strategy.
A full-featured GIS platform - built end to end.
Every requirement from LGED's ICT Unit and GIS team was implemented, tested, and deployed - from dynamic layer management to population analysis tools.
Dynamic Custom Map Generation
Toggle 40+ GIS layers and customize symbology, labels, and zoom levels for any project context.
Live DB–Shapefile Linkage
Road shapefiles joined with the GIS database at query time, surfacing attributes directly on the map.
Multi-Criteria Road Search
Locate roads by AADT, IRI, CVD, construction year, or last maintenance year across the national network.
Duplicate Road Detection
Cross-checks databases, highlights duplicates on the map, and generates a detailed checklist report.
Road Served Population
Buffer roads to estimate population served using settlement GIS layers and union-level density data.
School Unserved Area Mapping
Map settlements outside a service radius and quantify unserved areas for educational planning.
Road Density Map
Countrywide paved road percentage at upazila level in configurable density ranges for equity analysis.
Multi-Level Inventory Reports
Exportable at road, upazila, district, and project levels - lengths, counts, socioeconomic summaries.
Road Cross-Section View
Click any road to render a schematic cross-section from database attributes, exportable to image.
Role-Based Admin Control
Control layer visibility, aliasing, zoom rules, and database sync with tiered access levels.
Road Photo Integration
Site photographs surface in the attribute panel on road selection for visual condition assessment.
Project-Based Map View
Filter the map to project roads within district or upazila boundaries with linked inventory reports.
The GIS Map Viewer, used daily by LGED engineers.
Toggle 40+ layers - transportation, boundaries, points of interest, base maps - across the full national road network. Click any road to inspect attributes, exports, cross-sections, and photographs.
- Interactive layer panel with role-based visibility
- Sub-second attribute queries on a 10 GB network
- Satellite, light, and dark base-map switching
Architecture built for scale and longevity
Raw GIS shapefiles are transformed into a central PostgreSQL / PostGIS database via scheduled tasks. An intermediate GeoServer engine handles tile and feature serving. The frontend leverages AngularJS with OpenLayers and LeafletJS; the backend is an ASP.NET MVC RESTful API with Redis-backed session authentication and load balancing across dedicated servers.
