1.2 Million Houses In Lagos

At least, there are 1,194,525 houses in Lagos State, South West Nigeria housing the over 17 million population, the Lagos State Geographic Information System, GIS has revealed.

The GIS/Digital Mapping of project was commissioned by Governor Babatunde Fashola yesterday as the first in Nigeria and third in Africa behind South Africa and Kenya.

Through the GIS, the entire landmass of Lagos State, all industries and factories, roads, individual houses, among others have been captured while it makes it easy to transact businesses without necessarily leaving one’s house.

A GIS integrates hardware, software and data for capturing, managing, analysing and displaying all forum of geographically referenced information.  It allows for viewing, understanding, questioning, interpreting and visualising data in many ways that review relationships, pattern and trends in the form of maps, globes, reports and charts.

Speaking on GIS and its implication for Lagos State, Mr. Zul Jiwani, Orion Technologies, Canada disclosed that approximately 1.2 million houses had been captured in Lagos State using the GIS and Digital Mapping system.

According to Fashola, the project took about three years to fly over every inch of the 3,755 square kilometers of the state, to photograph every inch of land and building “which we have now successfully captured.

“The photographs are accurate to a point of 11 millimeters.  At the same time, we took data and bathymetric charts of the depth of every inch of water in the state in order to aid navigation and advise on dredging and strengthen our capacity for flood control.

“What we have today enables us to see from our offices, every building in Lagos and every piece of land without going to personally visit the site.  It allows us to determine the exact size of every piece of land; its precise boundaries and its topography from a desk in our offices.

“With GIS, we can know the number of street poles, water pipes, length of streets, nearest bus stops to your house, nearest school, nearest market, nearest hospital, among others.  We can therefore now produce and print plans and documents in quicker time, while citizens can obtain maps of landed property online and pay by electronic means without visiting Alausa,”  Fashola added.

According to him, “the Lagos Navigation System that helps commuters find streets and locations around our state from their computers or in their vehicles is now delivered with this project.

“We are also able to plan better the location of utilities of power, water supply, waste management facilities and so much more.  It will be a most useful asset in locating people and events, using GPRS and connecting with the GSM for detection of crime, responding to emergencies and so much.  With this GIS facility, the possibilities are simply endless.”

Commissioner for Science and Technology, Dr. Kadri Hamzat said the state government commenced the comprehensive Digital Surveying and Mapping of the whole state which resulted in the establishment of Enterprise GIS to provide various developmental activities in both the rural areas and other major towns in Lagos State, saying that the GIS was implemented using seven modules.

He stated that GIS is used for enormous amount of infrastructure and geographical planning, stressing that with GIS “you can map change to anticipate future needs.  Specifically, a Police Commissioner of the Inspector General of Police might use GIS to study how crime pattern change from month to month and at different locations to determine the development of officers.

“When rain falls, with GIS, it is possible to determine how it affects rivers and marsh lands.  This is possible using location reference system such as the longitude and latitude and perhaps elevation,” he explained.

  1. While applauding this great effort of Fashola’s administration in implementing a GIS solution at a State level, I am however not convinced that there is an effective business plan on ground to run the project as a professional and profitable business entity without the need to come back to the govt for more operational fund in the next 7years!

    There is very little information on how the general public can have access to the data. How much will it cost, how is it priced anyway? The project is already showing classic symptons of failure judging by previous failed GIS projects e.g. PIE. If the govt does not come up with the business case for it, i can predict that the project will undergo a natural death in the next 10years or another adminstration will need to invest over N3billion again to start a fresh project.

    To start with, does the project have even an interactive website like that of Google map where people can zoom in/out, do a search & find, pan, and generally play with the data?. I am not talking about pasting some nasty or dirty jpeg screen shots of street map in Arcview!!!!

    By the way, who is responsible for managing the project as a profitable business entity? Entrusting this N3billion babe to the Lagos State survey will be a great disaster!!. It will simply go the way of previous failed projects and we’ll be back to square one.

    I have no doubt that the project will meet international standards judging by the calibre of experts involved, I just wish the state govt will also invite the world-class reputable business consulting companies like KPMG, Accenture, etc to advice the government on how to market the project and turn it to a huge commercial success. This perhaps explains why mapping agencies like Ordnance Survey of UK had existed for the last 220years.

  2. Thanks Tony for enlighten us. We cared less for those who do not like the face of BRF. We love his work in Lagos.

  3. thank u.. Tony, this piece of enlighment has gone a long way in educating some of us who know little or nothing about GIS… Well done Sir

  4. Sorry guys u need to search for more info b4 u dispute the LAGIS project. LAGIS and AGIS projects do serve same purpose but the comprehensive modules, methodology and technology used by LAGIS is far more advanced than AGIS and the first in Nigeria.
    1. Orthophotos, LiDAR and DEM data are collected as end products whilst AGIS uses Satellite Imageries and old aerial images difficult to generate 3D/elevations cos their are no liDAR info., . The point resolution,data analysis and detailing cannot bet compared. Orthophotos are taken with Aircrafts cameras flown over the city. Please read more even in Wikipedia
    2. GIS is a tool for mapping, LAGIS used these info to generate maps, survey plans and introduced Enterprise GIS for use by any body to make ur map in the confort of ur room, office or so.. This will facilitate alot.
    The Enterprise GIS is rich in data not compared to the AGIS. Onpoint software was used, a leading company in custom software deisgn. Even the United States Dept of Defence use them.
    3. LiDAR info can help to generate 3D City model, we live in a 3D world. we the Surveyors understand what d benefits are. the Architects,builders, engrs in general understand that.
    4. A bathymetric survey of all water bodies was done to aid navigation and control flooding using d 3D city model and Lidar info. not in AGIS proj.
    5. The different methodologies gives different accuracies. The AGIS proj accuracy cannot be compared to LAGIS. LAGIS data is more accurate, and detailing is more accurate and it has a rich database system which can be applied to all facets of life. If u r not convinced giv mi an example of what u want to do and i will tell you how LAGIS will help and the limitations in AGIS.
    6. Because of the richer database of LAGIS it is important for the govt to do so for all states. Good for Nigerians.
    7. As i’m aware the LAGIS proj involved Men of honor in our survey profession, likes of Prof Fajemirokun, Prof Ayeni and Prof Iwilo, we grew up in this profession respecting them cos of their contributions to our field.
    We understand this project and it is one of the fastest growing and best surveying methodology used in the world today. Not the AGIS method.

  6. Habba,first in Nigeria and third in Africa?Mr Fashola? Kilode! Abuja I am aware has been using GIS since El Rufai was the minister of FCT. A lot of lies by politicians!

  7. haba, when will the lagos state govt. stop telling lies. lagosians open your eyes and stop being deceived by the sweetmouthed BRF. He is a lawyer and he is trained to be sweetmouthed

  8. @ TUNDE THOMPSON, YOU SHOULD HAVE REALISED BY NOW THAT TELLING LIES IS THE TRADEMARK OF POLITICIANS, ESPECIALLY IN NIGERIA. THANKS FOR THE ENLIGHTENMENT

  9. Whilst a good system, please note that Lagos GIS is not the first in Nigeria nor the third in Africa. Abuja GIS is already in existence and serves the same purpose…

    • Thanks for the clarification. How does one access the Abuja GIS website to download data? I am interested in getting the land records so I can view teh various plots of lands in the FCT.
