Hi Pierre, Apologies for the late response. The link was updated. If your TIN is small, you can use MDAL to read it. An example of such data (ESRI ADF TIN) can be found here: https://github.com/lutraconsulting/MDAL/blob/master/mdal/frmts/mdal_esri_tin.cpp With MDAL/QGIS, you can also display

Hi Pierre, Very interesting! We are trying to create a generic TIN reader/writer for open source applications: https://github.com/lutraconsulting/MDAL/ MDAL already supports a number of TIN/mesh formats and it is integrated with QGIS. It would be good to join efforts. Kind regards, Saber On
