==Map Background==
IMSMA<sup>NG</sup> is designed to support a variety of users from information managers to operations users. Recognizing that each user or group of users may require a different set of maps, IMSMA<sup>NG</sup> 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 MRE education coordinators may need only vector map layers to visualise MRE education activity data.
Using ESRI’s ArcGIS Desktop products, programmes can create custom .MXD files (or ArcMap-formatted maps) for each client, allowing users to visualize common data on different maps. Customisations of.MXD files can include adding and modifying raster and vector layers, label display, scale management and many other GIS functions.

| align="left" | Use only the layers you need || align="left" | When creating or customising maps, include only the layers necessary for map visualisation. Extra layers take up space and present users with unnecessary, confusing options. Consider tailoring specific maps for each user group, for example, building one map for MRE education activity users and a separate map for operations staff.

| align="left" | Limit raster layers || align="left" | Raster images take up a large amount of space compared to vector layers, causing slower system performance. Limiting the use of raster layers to one or two background images or turning them off by default can improve performance of the map display and IMSMA<sup>NG</sup> overall.
