I am preparing enviromental layers for use in MAXENT and have the CORINE land cover vector data which is in ETRS89 - LAEA, but my presence locations for the species are in Irish National grid coordinates. Can anyone tell me if/how it is possible to convert the two into the same coordinate system?

Hi jmacp,
Which software are you using to handle the data and can you provide more information about your desired output projection?
Thanks.

Hi - I'm using ArcGIS 10. The output projection needs to be the same for the presence locations (points, currently in Irish National Grid and British National Grid) and the environmental layers which I downloaded as shape files from EEA and are currently in ETRS89-LEA. I've tried using GridInQuest to convert but I can't get it to work! Any suggestions gratefully received.

Hi,
ERSI tools (like arcmap) are using a proprietary dialect for some projection systems. We normally provide OGC (open geospatial consortium) projections files with the datasets we publish. We can't customize our datasets to be totally compliant with processing environments which are not compatible with open standards. For ESRI users we do however provide a separate ERSI friendly prj file. In this case, download this last file, delete the prj file coming with the dataset (OGC standard), rename it to match the dataset name. Arcmap will then stop complaining.
Hope this helps.

Hi, thank you - I've done that but I still can't convert my point locations to match the shape file layers! Would it be possible to convert the shapefile layers into OSGB?

Ok, that leaves us a bit lost... we are pretty sure about our dataset. Perhaps we need to see a subsample of the dataset you are working on. May we ask you to contact our expert Mauro Michielon directly for further advise (Mauro.Michielon@eea.europa.eu).
