At Dr Vincent Clark & Associates we map with a passion and are able to bring various spatial data and complex survey information together into a high-quality cartographic visualisation. Our people are competent in working with a number of GIS and design formats and fulfil all heritage mapping requirements with sub-meter accuracy by employing differential GPS technology and other proven survey methods out in the field. Whether it be site recording and top plan illustration or geo-referencing and integrating old maps, terrain modelling and 3D topographic mapping, we aim to develop the most informative maps for inclusion in Cultural Heritage Management Plans and to assist in ongoing project analysis. All mapping and spatial data that we create is projected to the Geocentric Datum of Australia 1994 (GDA94) and Map Grid of Australia, zones 54 and 55 (MGA54, MGA55). The superseded Australian Geodetic Datum 1966 (AGD66) is also used for certain heritage requirements. Where possible, elevation data we collect is adjusted to the Australian Height Datum (AHD).

Vector data formats we can and typically use:

  • Shapefile (.shp)
  • Drawing Interchange Format (.dxf)
  • AutoCAD (.dwg)
  • Microstation (.dgn)
  • Google Keyhole Markup Language (.kml, .kmz)
  • Digital Elevation Model (.dem)
  • Elevation Grid (.xyz, .csv)

Raster formats we can use:

  • Enhanced Compressed Wavelet (.ecw)
  • GeoTIFF (.tif, .tiff)
  • Georeferenced JPEG (.jpg, .jgw)
