1Map-Natural Hazards Mapping

1Map is the name of a framework customized by MGI that enables the efficient creation of Web-based maps. Its user interface components are derived from the Google Maps APIs (Application Programming Interfaces). All maps built on the framework are URL accessible. 1Map enables all the traditional navigational and interactive map-type features of Google Maps including zoom, pan and retrieve location-specific information. In addition to these, a search feature has been added and this allows users to look up, pan and zoom to point locations that are found given a search string. The administrative functionality gives “administrators” the ability to edit feature information; persons without administration access credentials will only be able to view and search the mapped information.

A number of web maps have been created using this framework, and one such example is the Natural Hazards 1Map application that showcases historical point occurrences of floods and landslides across Jamaica dating back from 1962. This flood and landslide inventory is updated periodically with spatial data at the community level, obtained from the local press (online newspaper archives).
