Europe / Portugal

GIMLabs in Portugal

Portuguese projects on the mainland work in PT-TM06, on ETRS89.

Coordinate systems

Every project picks its own grid: search the picker for "portugal", the grid's name or its EPSG code. Set Portugal as your company's country and GIMLabs suggests PT-TM06 (EPSG:3763) for new projects. Portugal also falls in ETRS89 / UTM zone 29N (EPSG:25829), which any project can use instead.

PT-TM06

EPSG:3763

ETRS89 / Portugal TM06, the grid for mainland Portugal. The Azores and Madeira grids aren't in GIMLabs yet; UTM covers them in the meantime.

On ETRS89, so it converts to latitude and longitude without a datum shift. EPSG area of use: Portugal - mainland - onshore.

Your data, as written

What GIMLabs does with Portuguese letters and the files a project in Portugal brings in.

01

Letters

Text with Portuguese letters such as á â ã à ç é ê í ó ô õ ú keeps them through import, the table editor, log and figure PDFs, site plans, AGS and CSV exports and downloaded file names.

02

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 Portuguese. There is no need to re-save them first.

03

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.

04

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.

05

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.

06

Country and time zone

Choosing Portugal 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.
