Hello The Village boundary puzzle will always remain a puzzle. Recently I have worked on a Creating as good a Village Map as I could do for a Block in Uttarakhand consisting of only 125 Villages.
I had an earlier map that I had traced form the Patwari/Cesuns ,ap 20 years ago. But the areas of that map were in the range of 25% to eeven 200 % of the aera as per revenue department. The I took a map from Justin (on our group) for that area. It had many missing villages. After several days of retracing on Google Earth I created a better map. But it was time consuming just for 125 Villages. There are several issues 1. No one actually has correct georeferecned accurate enough boundaries. 2. Whatever is available is just the correct (to an extent) juxtaposition of villages. 3. Sometimes the Uninhabited villages are missing as in 2001 census Data. 4. It sis not necessary that the Habitation of a particular villages is within the Revenue boundary of that village. 5. Sometimes the habitations merge between two villages to form an apparently single village. Better and more accurate village maps can only be created IMO by having at least ONE POINT inside a Khasara or a survey number 100% accurately mapped and them merging them to get a Revenue village map. For large units of Survey numbers we will need More than one points. I am pessimistic about we ever achieving that accuracy in India. Because I have seen that even in a Specific Project based PAID Survey assignment for Engineering applications some surveyors FUDGE the data. There could be Good quality work in some pockets but when you mix Good Quality and Bad quality then the end result is bad quality and not average quality. We need to realise that.
