All prioritized requirements met
Modernizing infrastructure planning at a national scale.
The Local Government Engineering Department (LGED) is Bangladesh's largest government engineering agency, overseeing rural roads, bridges, markets, and socioeconomic infrastructure across the entire country. Despite maintaining one of the most extensive GIS databases in the region - with a road network dataset exceeding 10 GB - LGED lacked an interactive, web-based platform for its engineers and planners to work with that data dynamically.
StreamsTech's partner firm, Jantrik Technologies Ltd., was awarded a competitive government contract to design and deliver a comprehensive GIS-based web application for LGED's ICT Unit. The engagement spanned requirement analysis, full-stack web development, spatial data engineering, and quality assurance - all completed within a tight 3.5-month timeline and delivered on budget.
The resulting application became the foundation of LGED's web-based GIS infrastructure - enabling every engineer in the country to access dynamic, customizable road maps and project planning tools directly from their browser, without needing any 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.
