Modify an IMSMA Map

Note that these procedures are done outside of IMSMANG.

All modifications to the IMSMA^NG background maps must be performed in an external GIS application such as ArcMap 10.1.

1. Copy all layers to a folder ouside the C:\IMSMAng folder.
2. Change the .MXD file as needed. Example of edits:
   • Set minimum and maximum display levels for each layer
   • Add, modify, and remove raster and vector layers
   • Change the map coordinate system
   • Create pyramids for raster layers
   • Change colours and styles
   • Add, modify, or remove labels from vector layers
   • Group and ungroup layers

   Although an external GIS application allows you to make other changes to the map, the changes listed above are the ones that can be viewed with IMSMA^NG.

3. Save the .MXD file with a new name. Remember to use relative path to data sources in the map document (mxd).
4. Import the new .MXD file.
5. Test the new .MXD with IMSMA^NG and evaluate performance.
6. Share the new .MXD file and all layer files.
