Changes

{{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 {{IMSMANG implements }} 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 IMSMANG prior to beginning widespread use of the systemend-users.

For example, Land can be displayed in the Map pane with different symbols for priority, status and type. These symbols are stored in the '''[[IMSMA.mxd]]''' file and can be customised by information managers to operations usersas desired. Recognizing that each user or group of users may require a different set of mapsAdditionally, {{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.

Guideline Explanation{{note|Use only * Back up any customised map files including any font files (.ttf), style files (.style) and .mxd files, particularly the IMSMA.mxd file. {{IMSMANG}} does not automatically back up customised files.* Any problems caused by incorrect customisations can be corrected by replacing the updated IMSMA.mxd file with the IMSMA.mxd from the layers you need When creating or customising maps, include only original installation and reimporting the layers necessary for map visualisation. Extra layers take up space * All map changes, including symbology customisations and present users with unnecessarymxd changes, confusing optionsaffect only the computer on which they are applied. Consider tailoring specific maps for To share these changes to other computers, the customised files must be copied to each user groupcomputer and the map reimported.* If changes do not appear to be taking affect as expected in the newly updated map, for example, building one map for MRE users delete and a separate map for operations staffrebuild the sandbox.}}

Recognising that each user or group of users may require a different set of maps, causing slower system performance{{IMSMANG}} allows users to visualise data on maps individually tailored for their needs. Limiting the use For example, users in a regional Mine Action Programme office may need only maps of raster their region to display data while education coordinators may need only vector map layers to one or two background images or turning them off by default can improve performance of the map display and IMSMANG overallvisualise education activity data.

Tile maps Breaking up a map into multiple imagesUsing an external GIS application, or tiling theminformation managers can create custom .MXD files for each user, allows allowing users to turn individual sections visualise data on different background maps in the Map Pane. Customisations of .MXD files can include adding and off as neededmodifying raster and vector layers, which results in improved performancelabel display, scale management and many other layer properties.

Back up Following the .MXD files Keep backups of map(s) guidelines below, information managers can build easy-to-use, sustainable maps for visualising data in their state prior to importing them into {{IMSMANG. This makes later map customisation easier and speeds up the process of importing the maps again.}}:

==Map Themes and Symbology==IMSMANG comes with several symbology options for displaying mine action data on the map. For example, hazards can be displayed on the map with different symbols The coordinate systems available for priority, status and type. These symbols are stored use 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 manager, information managers can display the different attributes of any item that IMSMA are collected managed using single-select option lists on field report templates. For example, information managers can display the different symbols for the “Slope” values of hazards including “High,” “Medium,” “Low” and “FlatCoordinate System Manager window.” The example is shown in available coordinate systems from installation are the figure belowstandard ESRI's projections.  Figure 23Copy custom coordinate system projection files to appropriate folder in ''C:\IMSMAng\server\gis\coordinate systems''.

Changing In the symbology used '''Customisation''' menu &rarr; '''Coordinate System Manager''' to display data in IMSMANG is a multistep process (as shown in the figure below) that should only be undertaken by advanced users with an understanding of GIS.

Coordinate systems and formats are used for four different functions in {{noteIMSMANG}}:# limit which coordinate systems/formats are allowed for [[Enter Geospatial Data in the Data Entry Form |* Back up any customised map files including any font files (.TTF), style files (.STYLE) and .MXD files, particularly data entry]] in the imsma.mxd file.

==Projection and Coordinate Systems==All geospatial data in IMSMANG is stored in LLWGS84 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 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. {{HowTo's|[[HowToCategory:Add a Coordinate System|Add a Coordinate SystemCRI]]|[[HowTo:Change the Display Name of a Coordinate System|Change the Display Name of a Coordinate System]]|[[HowTo:Remove a Coordinate System|Remove a Coordinate System]]}}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 client’s locale 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.{{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}}
