Geomapping Analyst

Job Summary

We are seeking a Geomapping Analyst to assist in mapping, spatial data management, and

routing support across Lagos Mainland and Island. The role involves working with

OpenStreetMap, Overpass Turbo, GraphHopper, and other mapping platforms to support

accurate zone creation, data visualization, and route planning under guidance from senior

mapping staff.

This is an entry to mid-level role, ideal for candidates looking to build experience in GIS,

geospatial data, and mapping systems.

Key Responsibilities

● Design, develop, and maintain custom map layers and zoning systems covering both

Lagos Mainland (e.g., Yaba, Surulere, Ikeja, Maryland, Gbagada, Ogudu) and Lagos

Island (e.g., Ajah, Badore, Sangotedo, Awoyaya, Lekki, Victoria Island, Ikoyi, Epe).

● Extract, process, and clean spatial datasets from OpenStreetMap, Overpass Turbo, and

other mapping sources, converting them into GeoJSON, KML, GPX, or shapefile

formats.

● Process, clean, and integrate CSV data containing all property submission logs with

coordinates, ensuring accurate mapping of properties and estates.

● Independently create and maintain maps, zones, and routing systems to support

operational planning.

● Create, update, and optimize driving and routing maps using GraphHopper or similar

routing engines.

● Visualize zones, estates, and street networks in GIS or mapping platforms to enhance

operational clarity.

● Validate map data against real-world conditions and property submissions to ensure

accuracy and reliability.

● Develop and maintain scripts or tools (Python, JavaScript, SQL) for map automation,

data validation, and route optimization.● Identify gaps or inconsistencies in map data and resolve them through updates,

corrections, or field verification.

● Continuously monitor and improve map coverage, accuracy, usability, and routing

efficiency to support operational performance.

● Support data integration and visualization within company dashboards and GIS

platforms.

● Document mapping workflows, zoning logic, route optimization decisions, and dataset

transformations for internal reference and future onboarding.

Required Skills and Qualifications

● Hands-on experience with OpenStreetMap (OSM) and Overpass Turbo for extracting

and processing spatial data.

● Experience with GraphHopper, OSRM, or similar routing engines capable of creating

optimized driving and cycling routes.

● Strong coding/scripting skills (Python, JavaScript, or SQL) for processing CSV data

containing property submission logs with coordinates and automating map tasks.

● Proficiency with GIS tools such as QGIS, Mapbox, Leaflet, or MapLibre for visualizing

zones, estates, and street networks.

● Ability to manage and maintain spatial datasets in GeoJSON, KML, GPX, or shapefile

formats.

● Strong analytical and problem-solving skills, including route optimization for cycling and

driving efficiency.

● Attention to detail and spatial awareness to ensure accurate maps and coordinates.

● Ability to work independently and take full ownership of mapping, routing, and data

management tasks.

● Knowledge of Lagos geography, estates, street networks, and practical cycling/transport

routes for operational planning.

Preferred Qualifications

● Bachelor's degree in Geography, GIS, Urban Planning, Computer Science, Data

Science, or a related field.

● Experience with property submission mapping or real estate operations is desirable but

not mandatory.

● Proven experience in route optimization for cycling and driving, especially using

GraphHopper, OSRM, or similar platforms.

● Familiarity with dashboard integration or visualization tools for spatial data (e.g., Power

BI, , Tableau).

● Prior experience with spatial data automation, API integration, or GIS scripting.

● Knowledge of Lagos Mainland and Island geography, including estates, street networks,

and urban layouts.

● Understanding of logistics, delivery, or rider operations to optimize operational routes

effectively.

● Strong documentation skills for mapping workflows, zoning logic, and route decision

processes.
