Europe / Ireland

GIMLabs in Ireland

Irish projects work in Irish Transverse Mercator, or in the older Irish Grid many records still use. Both cover Northern Ireland too.

Coordinate systems

Every project picks its own grid: search the picker for "ireland", the grid's name or its EPSG code. Set Ireland as your company's country and GIMLabs suggests ITM (EPSG:2157) for new projects. Ireland also falls in ETRS89 / UTM zone 29N (EPSG:25829), which any project can use instead.

ITM

EPSG:2157

Irish Transverse Mercator (ITM) on ETRS89, the current grid for the island of Ireland.

On ETRS89, so it converts to latitude and longitude without a datum shift. EPSG area of use: Ireland - onshore. United Kingdom (UK) - Northern Ireland (Ulster) - onshore.

Irish Grid (TM75)

EPSG:29903

Irish Grid (TM75), the older grid that many maps and historic records still use. The two grids give different numbers for the same point, so check which one a file uses.

Converts with EPSG's published datum shift (TM75 to WGS 84 (2)), good to about a metre: plenty for the map, not a survey-grade conversion. EPSG area of use: Ireland - onshore. United Kingdom (UK) - Northern Ireland (Ulster) - onshore.

Your data, as written

What GIMLabs does with Irish letters and the files a project in Ireland brings in.

Letters

Text with Irish letters such as á é í ó ú keeps them through import, the table editor, log and figure PDFs, site plans, AGS and CSV exports and downloaded file names.

CSV files

CSVs saved as UTF-8 or UTF-16 import as written, and so do files Excel saves in Windows-1252, the code page Windows uses for Irish. There is no need to re-save them first.

Excel workbooks

Drop an .xlsx on the import dialog and each visible, non-empty sheet imports as its own table. Workbooks store text as Unicode, so letters always come through.

AGS

AGS4 files import and export. AGS4 Rule 1 only allows plain ASCII, so letters beyond Western European ones import with a warning, and the "ASCII only (strict AGS4)" export option writes a file a strict checker accepts.

European geology

On Pro, the Manage map adds EuroGeoSurveys' EGDI 1:1 million surface geology for the whole of Europe, as two layers: lithology and age. Click a unit for its lithology, age and the survey that mapped it. The data is CC BY 4.0, and GIMLabs credits it wherever the layer is shown.

Country and time zone

Choosing Ireland in Product OS fills in the company's time zone, which dates and times in Manage, Insight and Connect are shown in.

Still UK-first

GIMLabs started in the UK, and a few things still show it. See what works across Europe.

Description checks follow BS 5930

The automatic soil and rock description checks follow BS 5930, the UK standard. They don't check against EN ISO 14688 or 14689 yet, so read their suggestions with that in mind.

AGS is a UK format

GIMLabs reads and writes AGS4, the UK data transfer format, and also imports CSV and Excel and exports CSV, so you don't need AGS to bring data in or take it out.

Other datums are good to about a metre

Grids on ETRS89 convert without a datum shift. Grids on other national datums, such as Amersfoort, MGI or S-JTSK, use EPSG's published shift, good to about a metre: plenty for the map, not a survey-grade conversion.

Some map layers are UK only

BGS geology, coal mining and historic Ordnance Survey layers cover Great Britain, and the Environment Agency's cover England, so they are left out for projects outside Great Britain.

The app is in English

Screens, emails and help are in English. Your data can be in any European language written in the Latin alphabet.

Other countries

National grids GIMLabs has elsewhere in Europe. Not listed? Every European project can use ETRS89 / UTM, or ask us about your national grid.
