Standards: Triangulated Irregular Network Text File Format Specification Released

I’m pleased to announce the release of the second open technology standard at the SurveyOS Project today. The standard being released is Version 1 of the Triangulated Irregular Network Text File Format Specification. The format defines a simple delimited text file format that allows for the storage and transfer of TIN surface data. The goal of the standard is to increase the portability of TIN surface data frequently created by land surveyors and other geospatial professionals.

The release of this specification includes a fully sample of the new file format for the TIN Storage File type and a diagram.

Julian Padilla and I are working on a Google Summer of Code Project to create an open source Java library for TIN creation and analysis. We hope to add support for the file format as part of the library.

I’d also like to support this format in OpenJUMP.

Please contact me at or if you are interested in working on the specification or supporting it in your software.

You can download a zip file of the Triangulated Irregular Network Text File Format Specification, which includes the specification, a sample file, and a diagram, from SourceForge.
