Once the Map Viewer site is complete it is intended to update it every 24 hours. Until that time notification of completed revisions will be posted to subscribers on our mailing list and to the metedata section. If you would like to be notified of changes to the posted NHA, SAC or SPA data please contact NPWS_GIS@environ.ie. The old heritagedata mailing list will remain in operation so there is no need to reapply to join the new list.
Please refer to the main site for general NPWS contacts as the NPWS_GIS@environ.ie will only respond to GIS specific queries.
