Montserrat’s Geospatial Maps Outdated, Says Audit Report

GIS map which outlines the rivers and ghauts on island.

A Post-Implementation Benefits Study Report on the Geographical Information Systems Centre’s Montserrat Land Info – Online Mapping Portal, was presented to the Legislative Assembly December 17th, 2019, said a release from the Office of the Auditor General.

The report found that the GIS department which sits under the Ministry of Agriculture had been unsuccessful in its numerous attempts to acquire a drone to allow for the updating of the island’s maps which are outdated.

The purpose of this review include whether the MLI Online Mapping Portal: (i) met the original project objectives (ii) adhered to the requirements of the system development methodology, (iii) establish any plans for future enhancements.
This audit was conducted in accordance with the International Standards for Supreme Audit Institutions (ISSAI) 100, 5300, and ISAE 3000 and other internationally accepted IT related standards and guidelines.

Key Findings & Recommendations
The main findings and key recommendations of this Post-Implementation Benefits study were as follows:

  • GIS technology has been utilised in various ways and in several sectors, on island, such as: Crime; Telephone/Network services; Disaster Management; Land Information; Surveying; Tax Management; Statistical Information; Volcanoes; Coastal Management; provide support in Geothermal Energy project;
  • We found that the aerial photography dataset of the geo-spatial database is very outdated, as the last aerial photography of Montserrat was taken in 2010. The Geographical Information Systems Centre’s (GISC) numerous proposals for financial aid to procure a drone to collect the latest geo-spatial data of Montserrat have been unsuccessful. We strongly recommend that MATLHE purchase a drone for the capture of aerial photography of Montserrat’s current terrain, in order to update the very outdated imagery dataset.
  • The Lands & Survey Dept. (LSD) has not been continuously updating the GIS data with cadastre map/sheets, as they do not have any work protocols that mandates the updating of the database.
    Efforts are already being made by the department to resolve the issue.
