{{note|Any changes made to {{IMSMANG}} maps apply only to the client on which the changes were made. To make system-wide map changes for client-server installations, updated maps must be imported on each client installation.}}
==Map Themes and Symbology==__NOEDITSECTION__
{{IMSMANG}}comes with several symbology options for displaying mine action data on the map. For example, Lands can be displayed on the map with different symbols for priority, status and type. These symbols are stored in the .MXD file and can be customised by information managers as desired. Additionally, {{IMSMANG}} allows information managers to create subthemes for each item. Using the Subtheme managerSub-Themes Manager, information managers can display the different attributes of any item that are collected using single-select option lists on Data Entry Form templates. For example, information managers can display the different symbols for the “Slope” values of Lands including “0-5%,” “5-10%,” “10-15%” and “15-20%.” The example is shown in the figure below.

* Any problems caused by incorrectly configured map customisations can be corrected by replacing the imsma.mxd file from the original installation and reimporting the map.
* All map changes, including symbology customisations and .MXD changes, affect only the client on which they are applied. To propagate these changes to other clients on the server, the customised files must be copied to each client installation and the map reimported.
* If changes do not appear to be taking affect as expected in the newly updated map, delete and rebuild the client sandbox to ensure the GIS has the most up-to-date data.}}
==Projection and Coordinate Systems==__NOEDITSECTION__
All geospatial data in {{IMSMANG}} is stored in LLWGS84 WGS1984 decimal degree format, but {{IMSMANG}} can display data in virtually any coordinate system. {{IMSMANG}} comes with all the coordinate systems available to ArcGIS Desktop products like LLWGS84 WGS1984 and MGRS, yet information managers can add other systems their programmes use including UTM and national 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.

|[[Add a Coordinate System|Add a Coordinate System]]
{{note|
* Coordinate systems added via the Coordinate System manager are available to all users connecting to the {{IMSMANG}} server. If customised .PRJ files are used, information managers must copy these files to each client to ensure the accurate display of coordinates in the new system.
* Limiting the available coordinate systems within {{IMSMANG}}, for example, one or two UTM zones and a national system, simplifies coordinate data entry and visualisation.

{{note| To add, change, or remove coordinate systems, you must have the Reference System Manager permission.}}
The coordinate systems displayed in IMSMA are managed using the Coordinate System Manager window. The available coordinate systems are from ESRI. IMSMA does not support custom coordinate systems at this time.
