Tamilnadu village map

Hello sir, we have agriculture patta land in Tamilnadu inherited from our grandfather. All our lands are covered with fencing on all 4 sides since 20 years. Recently a person in the village have put a collector petition mentioning there is a foot path (called as nadapadai) connecting to the neighbouring village through our patta land as per village map. In recent FMB ( field measurement book) there is nothing mentioned about footpath. When I took the village map which is of 100 odd years old there seems to be a dotted line(signifies footpath) which is intersecting inbetween our patta land. We are doing agriculture in our patta land since 40 years and no one until now have objected or asked about foot path. Because the dotted line is going inbetween our patta land and giving way for footpath will substantially decline the land value. My questions 1. Is the village map which is of 100 years is still valid today ? Because we have done the survey recently and the latest surey/FMB sketch shows nothing about footpath in our patta land. 2. If we object to give way for foothpath how should I proceed legally.? 3. Can I raise a petition to collector to consider an alternative approach for footpath 4. Ours is a patta land and is it justifiable to give footpath even if it's mentioned in village map which is 100 years old .
