Hi I have a question which I am have difficulty putting in words but I'll try anyway...
Can anyone suggest how large data vendors organise their raster and vector data with the view of having the flexibility to update, reorganise, manage and search/query. How can this process be automated using the various OS GIS components (e.g. PostGIS, Mapserver, etc). Are data sets divide into categories. How does one deal with temporal variability over the same extents? Is their an ideal way of organising the data on disk? How should the various mapserver components like Mapfiles be organised internally and on disk? Understandably it could get very ugly as data increases. >From my limited experience I am thinking of some categories like: RASTER: * Orthophotos * DEMs * Multispectral * Panchromatic * Hyperspectral ... VECTOR: * Air Infrastructure * Rail Infrastructure * Road Infrastructure * Water Infrastructure * Geology * Contour * Admin ... this could go on forever... Then having some way of mapping their spatial locations and locations on disk along with metadata info into PostGIS tables. I'd like to get some feedback from anyone who has had similar experience thanks in advance shoaib
