Recording, organising and interpreting geospatial data
What is GIS?
Geographic Information Science or Geographic Information Systems (GIS) are used in archaeology to visualise, link and manipulate geospatial data. Recording is done with either survey equipment or by pencils and permatrace with non-geospatial data recorded in site registers and context sheets.
How is GIS done?
L – P use QGIS, an Open Source package, for which we have developed a suite of plugins for digitising the drawn record and linking to our ARK system. If you have an existing site archive or are in the process of creating one, we can help to extract information from data. Data contained in GIS files can be used to produce attractive and useful illustrations for reports or to create interactive maps for websites accompanying reports. GIS can also be used to help write reports, by providing software to query the data and identify patterns.
When do you need GIS?
Any archaeological project will produce geospatial data. L – P can help out at any stage of the project. We can design a GIS database to enable you to organise your data, generate the spatial data in the field with surveying or by digitising existing records or legacy datasets.
