{{IMSMANG}} is designed to support a variety of users from information managers to operations users. Recognising that each user or group of users may require a different set of maps, {{IMSMANG}} allows users to visualise data on maps individually tailored for their needs. For example, users in a regional Mine Action Programme office may need only maps of their region to display data while education coordinators may need only vector map layers to visualise education activity data.

All geospatial data in {{IMSMANG}} is stored in WGS1984 decimal degree format, but {{IMSMANG}} can display data in virtually any coordinate system. {{IMSMANG}} comes with all the coordinate systems available to ESRI's products like WGS1984 and MGRS, yet information managers can add other custom coordinate systems. Using the Coordinate System manager, information managers can add coordinate system and projection (or .PRJ) files to {{IMSMANG}} and establish a set of relevant systems that can be used for coordinate data entry and visualisation.
In addition to customised coordinate systems and projections, {{IMSMANG}} supports the use of localised number formats for coordinate entry, for example 73.233 or 73,233. {{IMSMANG}} validates all numeric coordinate data based on the computer's locale/regional settings so users running in a locale that uses a comma as a decimal separator can enter 72,333 while users running in a locale where a period is the decimal separator can enter 72.233.
