What is Intrasis?
Intrasis is a GIS designed to handle and structure geographical data, attribute data and document data. It is a tool for any company or organization with the need to enter such information from several users working within the same project. The metadata is especially designed for archaeological documentation and field data. The software is flexible and user friendly.

By using Intrasis all data related to one project or site becomes easy accessible and possible to combine. This increases the possibilities of interdisciplinary research when data from for example osteology or paleo-ecology can be combined with the archaeological information.

The system is designed and owned by The Archaeologists at the National Historical Museums and the software licenses can be purchased from us.

Since April 2000 Intrasis has been used at all archaeological excavations made by us and is today used by almost all major archaeological institutions in Sweden. It is also used in e.g. Denmark, Norway, Iceland and Great Britain. Intrasis 3 has been in use at Contract Archaeology Service since April 2013.


Patch for
Intrasis 3.1.1
We have now released a patch for Intrasis 3.1.1. It fixes some known bugs and we also add some minor features: Graph View will be limited to 10 000 objects and a message will show if this occurs. Information will also be given about objects causing a relation loop. Layouts can now be exported with the limitation "Clip output to graphic extent". You will notice an increased performance and stability of saved projects and GIS View(s). In the Import Wizard problems with failure due to missing coordinate system information for background layers is solved. Reprojection of survey data with manual input of coordinate system (ISD, GSI and XYZ) is fixed. The patch is available for download here.
