Choropleth Maps Of Nigeria by 7thCANON: 12:41am On May 04, 2016
Hello webmasters, Geographic Information Systems (GIS) enthusiasts, and data visualization experts, kindly check out Nigeria's first website that integrates data visualization with geospatial information via dashboards and choropleth maps. Here is a GIF file showing basic functionalities of the website.



Our target is to have at least 500 indicators fed into the map before the end of the year. Nigerians are free to send cross sectional data on any socio-economic indicator covering all the states in Nigeria to us so we can update the database. The website is presently hosted here: http://www.spidersolutionsnigeria.com/NGRChoroplethMaps/index.php .

Interesting, can you explain better.

Choropleth map
A choropleth map is a thematic map in which areas are shaded or patterned in proportion to the measurement of the statistical variable being displayed on the map, such as population density or per-capita income. The choropleth map provides an easy way to visualize how a measurement varies across a geographic area or it shows the level of variability within a region.

Dashboard
a dashboard is an easy to read, often single page, real-time user interface, showing a graphical presentation of the current status (snapshot) and historical trends of an organization’s key performance indicators to enable instantaneous and informed decisions to be made at a glance.



1. This is the control to hide/show the base map. We are using openstreetmaps as our basemap. If this control is changed, our platform will look like this



2. This is the control (dropdown menu) that enables users to select the socio-economic indicator to the mapped in the choropleth map. Depending in the indicator selected, the summary by geopolitical zones will be plotted as a piechart or barchart in {3} while the top and bottom five states will {9} and {10} respectively.


3. This shows the summary of the selected indicator by geopolitical zones. This may be a barchart or piechart depending on the indicator selected.
4. This is the zoom control for the active choropleth map
5. This is the title of the active choropleth map
6. This is the information box for the active choropleth map. As users hover their mouse on the states, the name of the state and the value of the active socio-economic indicator will show here. In addition, on the name of state and the value also show as a popup above the state where the mouse is over.
7. This controls the opacity of the choropleth map. The present value of the opacity is shown in {8}. If the slider is moved left to change the opacity to 0.5, the map will look like this


8. This shows the current opacity of the map
9. This shows a list of the top-five states based on the selected indicator
10. This shows a list of the bottom five states based on the selected indicator
11. This is the legend for the choropleth map
12. This shows the source of data used for the choropleth map.

Ok, thanks for the info.

What applications would you suggest it be used for, seems more like an official resource supposed to be utilized by govt organizations.

It for general data visualization of different cross-sectional data by states and to appreciate the geospatial differences across the states vis-a-vis any selected indicator

Hi,
What technology did you used? Am currently conducting a research on a web based Mapping and web GIS.

Impressive.

How do you gather and verify the data?

The platform is developed using mainly web-based languages i.e. html/php, css, and javascript. The charts are developed with the support of javascript-based chart libraries while the choropleth is developed with the support of javascript-based mapping libraries. One will need to be very conversant with GIS softwares (ArcGIS or QGIS), javascript/jQuery, and frameworks for developing interactive dashboards to be able to pull it through.

The data used are sourced mainly from the website of National Bureau of Statistics. The source of the data for each selected indicator is shown at the bottom of the map (see Panel #12 in the first image).
Re: Choropleth Maps Of Nigeria by tpiah01: 1:07am On May 09, 2016
oh, ok.

I was thinking it might be similar to the marketing apps used for data analysis and research.

When is the time frame estimated for release?

Ok thanks. I noticed QGIS - qgis2web plugin, played some part in you webmap?

Ii have had this in mind for a long time....
The important question is .what is the.source of your data

There is no specific time frame. We will be updating the list of indicators regularly as different indicators become available (indeed we are presently working on updating it as I am typing this). Our target is to have at least 50 indicators before the end of May.

Yes, the qgis2web plugin was very helpful in generating the geoJSON data used.
