Spatial Discovery
Interactive online viewer of historical maps
The project was about developing a web application for publishing a large collection of high-resolution historical maps. It was about ten thousand of images in that collection.
The main idea was to show the historical maps on top of the base map provided by Google. It was required to provide tools for elementary spatial analysis and research such as layer management, transparency control, swiping, spyglass, cutline removal and similar.
The main customer of the application was the National Library Board of Singapore.
The user requirement study started in spring 2015. The final acceptance and commissioning were completed late autumn the same year.
Currently, the application is in production and used intensively.
This project is connected with two other projects I participated in: istream and ImaGeoRef.
Below is the list of what I was doing in the propject:
- User requirement study. I was talking to the NLB team, analysing and documenting all the requirements. I prepared a few prototypes during that stage.
- Leading the programming team and core development;
- Development of the database for the Microsoft SQL Server DBMS.
- Development of the backend part of the solution:
- Development of the public frontend with Backbone.js, Marionette.js and OpenLayers.
- Development of the administrative console application with Sencha ExtJS 6;
- Deployment of the solution on the servers running CentOS 6.
Below are a few illustrations to give you a visual impression of the web application.
