Data Conversion

Different File Formats

Data interoperability is increasingly a problem in today’s organisations.  A profusion of data from public sources, organisational mergers, and new data standards mean many businesses are faced with multiple file formats, across numerous projections, which makes it difficult to use and effectively integrate data into corporate planning.    

On the other hand, correct data, in the right format, eliminates barriers to data sharing and enables the GIS professionals in your organisation to focus on analysis rather finding and converting data.
