comment Generating a vector contour map of fictional terrain
This is almost bordering gaming/CG animation environments and fractal mathematics. The software does exist, just not sure it's related to GIS. It might be possible to do the whole thing in GIS but you might still need to provide extensive manual input - define continents and mountain ridges, etc. The possibly using some interpolation techniques or TIN triangulation generate some type of a terrain. Digital elevation rasters (from which contours are derived) are complex representations of the real world, usually acquired by using various remote sensing techniques.

comment Problem in multiple dataframe visibility in arcgis 10
Can you verify you are using version 10.2.1?

comment Why does a raster with resolution 5x5m not create a grid with these dimensions?
Based on the images shown above the distance between the points is not 5m but more like 50m. Also, as mentioned, please provide the exact steps and parameters of the interpolation process.

comment Problem in multiple dataframe visibility in arcgis 10
Can you confirm that the backround colour of the dataframe in question is set to NONE! Not white or any other colour? What version of ArcGIS do you have. As I mentioned, there is no loss of transparency in the newest version (10.2.1). I suggested AI as a workaround - you can open in Illustrator, locate the background fill, delete it and resave as PDF without loosing quiality. Alternatively, you can export only the inset maps to EMF. This will enable you to add id to arcmap as image and it honors transparency.

comment Compacting ESRI file geodatabases…good practice?
I think @spg answered your question. Can you please check it as answered. As was already pointed out, exploring and analyzing the subtleties of a file geodatabase read/write/commit speeds might be difficult to objectively quantify.FGDB is a personal geodatabase suitable for desktop computing environments. If subtle performance increase is of utmost importance you may want to explore a true enterprise Spatial RDBMS for your backend.

comment Create Ms-Access type queries in ArcMap
Please limit your question to only 1 question and post examples; SQL query you run in Access that you would like to replicate in ArcMap. Personal (MS Access back-end) geodatabase has more querying options than File Geodatabase and you can also use all Acceess database SQL features programatically altough and or use OLE DB connection.

comment How to georeference Tiffs after manipulation in Photoshop?
Yes - go to properties of the edited tiff in ArcCatalog and assign the same Spatial Reference in the properties. However even without this process the tiff should appear in the correct location but displays a warning that Spatial Reference is missing.
