Solutions Mew ls eet he TT Brunswick It is often desirable to carry out GIS analysis using an area which exceeds the size of an individual ETB File window When this situation occurs adjacent files may be joined to create a new file with a larger spatial extent Depending upon the GIS software employed it may be possible to merely build a data base index which associates the adjoining files and maintains connectivity among them This is sometimes referred to as tiling In CARIS this association is referred to as a continuous data base It may be necessary to merge all data from individual files into one new file with an expanded coverage area When individual files are merged to create a new file GIS software performance may degrade due to the increased file size and the number of features within it Unnecessary features may be removed from the file to reduce storage requirements The file resolution may be made more coarse Note that this may cause problems with topological relationships This solution should only be used by experienced GIS users and only under certain conditions Service New Brunswick UGE19980 Services Nouveau Brunswick Version 0 8 March 6 2001 Users Guide to the Digital Topographic Data Base DIDB98 of New Brunswick 96 Data Filtering Definition Data filtering is the systematic removal of unnecessary topographic features through the use of a search criteria based upon topographic feature attrib
