IMSMA<sup>NG</sup> {{IMSMANG}} includes an embedded GIS component, the [[Map Pane]], based on ESRI’s ArcGIS 9ArcEngine 10.x 1 that allows users to visualize visualise mine action information on an integrated map without moving to another application. While IMSMA<sup>NG</sup> implements {{IMSMANG}} includes many standard GIS features, information managers can augment the provided capabilities with should consider to use an external GIS applications such as ArcGIS Desktopin order to perform GIS analysis of the data in {{IMSMANG}}. The map used in {{IMSMANG}} Map Pane (the background map) should be customised so it fits the needs of the Mine Action Programme. Since these the customisations can of the background map will have an impact on the performance and usability of the system{{IMSMANG}}, it is important to consider test the implementation before sending the necessary new background map and GIS customisations for IMSMA<sup>NG</sup> prior to beginning widespread use of the systemend-users.

Recognizing that each user or group of users may require a mxd]]}}{{IMSMANG}} comes with several symbology options for displaying the Mine action data in the Map pane. For example, Land can be displayed in the Map pane with different set of mapssymbols for priority, status and type. These symbols are stored in the '''[[IMSMA<sup>NG</sup> .mxd]]''' file and can be customised by information managers as desired. Additionally, {{IMSMANG}} allows users information managers to visualise data create new sub-themes for each item. Using the Sub-Themes Manager, information managers can display the different attributes of any item that are collected using single-select option lists on maps individually tailored for their needsData Entry Form templates. For example, users information managers can display the different symbols for the “Slope” values of Land including “0-5%,” “5-10%,” “10-15%” and “15-20%.” The example is shown in a regional mine action programme office may need only maps of their region to display data while MRE coordinators may need only vector map layers to visualise MRE datathe figure below.
Using ESRI’s ArcGIS Desktop products, programmes can create custom [[Image:AdminGuide_ExampleDisplayDifferentSymbols.MXD files (or ArcMap-formatted maps) png|center|500px|''Example of Displaying Different Symbols for each client, allowing users to visualize common data on different maps.

To make system-wide map changes for client-server installationsFor example, updated users in a regional Mine Action Programme office may need only maps must be imported on each client installation}}of their region to display data while education coordinators may need only vector map layers to visualise education activity data.
Using an external GIS application, information managers can create custom .MXD files for each user, allowing users to visualise data on different background maps in the Map Pane. Customisations of .MXD files can include adding and modifying raster and vector layers, label display, scale management and many other layer properties.
Following the guidelines below, information managers can build easy-to-use, sustainable maps for visualising data in {{IMSMANG}}:
