Feature extraction is the process of extracting 2D features and converting them to 3D vectors for use in a GIS. Examples could include land parcel boundaries that have been hand-coloured on a paper map. We would extract the boundaries as shapes and then attribute the shape with information based on, for example, what the colour infill denotes (e.g. arable). We can extract multiple parcels from a single map and assign different attributes to each parcel type. These individual parcels are then output as a single file (for example .shp or tab) that can be overlaid on current mapping or aerial imagery.

Max are able to provide an end-to-end solution that includes scanning the maps and drawings as high-res tiffs, converting these image files to geo-referenced versions (geo-Tiff), extracting relevant features as geometry and then delivering these files through a web GIS (if required).
