GIS Web Services Guide

You can access the API ArcGIS REST web services by clicking on the links on data.gov.ie.

(Screenshot of data.gov.ie Archaeology survey website page indicating the ArcGIS REST Services Directory links)

Clicking on the link will take you to the ArcGIS REST Services Directory, where you can copy the Url or API to insert the live service in your ArcMap, ArcPro or QGIS project.

(Screenshot of the ArcGIS REST Services Directory indicating SMR url)

The url highlighted in the screenshot above can be added to a GIS project, this will add all the map server layers to the project

Further to note if you have successfully added the REST services to your project but they are not visible in your map pane, check the contents pane to see if the visibility tick is grey’ed out (see screenshot below) indicating that a visibility range has been set

(Screenshot of contents pane illustrating greyed out tick)

You can either zoom in to see the data or you can change the “Out beyond (minimum scale)” to none in the layer properties dialogue box (see screenshot below)
