Appendix 6 Technical Overview of the Application
Overview
Developed for the project the Merseyside Historic Characterisation Application
(MHCA) is a Visual Basic application that has a GIS front end allowing for the
digitisation of underlying historic maps and bespoke data input forms for the
subsequent capture of characterising features. The front end has an innovative dual
window display, allowing maps or aerial photographs of differing ages to be displayed
simultaneously at the same zoom and location. Captured data is stored in an Access
database, enabling easy querying and analysis of the data by the client.
Components
The Merseyside Historic Characterisation Application comprises a Visual Basic front
end, incorporating a MapInfo component with a MapBasic interface and utilises a
Microsoft Access database for the data storage component. The following diagram
shows the relationships and flow of data between these components.
