Layer Identification

Layers get identified by the so called layer identifier. The layer identifier can be made out of:

layer name

top level group name

top level group name // layer name

top level group name // group layer name


So if the map document contains multiple group levels in the table of contents, only the top level group layer name is saved in the layer identifier together with the layer or group layer name. Therefore, it is possible to assign identical layer names or group layer names in two differing top level group layers. On the other hand group layers of lower level will NOT be considered in the layer identifier. This is the reason why unique layer names or group layer names are necessary in differing group layers of one top level group. See the screenshot below for details how layer and group layer nomenclature will affect the formation of layer identifiers. On the left the original table of content is displayed, on the right it is possible to see which layers would have to be renamed because of identical layer identifiers.



Layer identification in WebOffice 10.9 SP1 - Identical layer or group layer names are only possible once per top level group


The reason for identifying layers this way (instead of referring to the table of content-position dependent ArcMap layer id) is that you do not have problems when moving layers within your map document.

Whenever the layer identifier changes, WebOffice author updates the changes.



Whenever you change the ArcMap document, the related WebOffice 10.9 SP1 project should be opened with WebOffice author – otherwise WebOffice author is not able to update layer identifier changes correctly. After changes have been done, ArcMap document changes as well as WebOffice 10.9 SP1 configuration changes need to be saved.

WebOffice 10.9 SP1 only supports the use of sequential layer IDs within the appropriate service. The parameter Allow assignment of unique numeric IDs for map service publishing via the settings of the dataframe within ArcMap is not supported with WebOffice 10.9 SP1.
