Our data capture experience ranges from the relatively simple digitising of point applications such as street lighting networks and tree preservation orders, to the development of complex and structured databases using stringent validation rules and inference techniques. Data can be captured from a variety of sources including film and linen plans as well as paper records and microfiche.
Data Audit and Clean-up / Consultancy
Prior to embarking on a data capture project it is often necessary to undertake a data audit or data clean-up exercise. This typically involves ascertaining:
We are happy to undertake these activities on behalf of a client as part of our consultancy service. We can also lend the benefit of our experience to advise on the best method of data capture for a given project.
Should a client have a small amount of data capture they wish to undertake themselves, we can provide tailored training to help ensure the best use of data and time is made.
There are many kinds of data that can be usefully incorporated into a GIS.
Sometimes digital data is available from other
sources and this can be converted into a format suitable for inclusion in the
system. Textual data can be input into
proprietary databases, such as Access, which can be linked to a GIS, and an
organisations’ own existing maps can
be scanned and georeferenced instead of using OS vector background mapping.
Various techniques to ensure data integrity are central to all our work. We run a number of specially designed programs to eliminate inconsistencies such as:
These programs are particularly important as some systems do not accept inconsistencies.
Data produced by CDR Group can be delivered in the various forms of plotted maps (mono or colour; with or without background mapping), record cards, spreadsheet analysis or on magnetic media. Digital data is provided in all popular GIS formats.
