Re: [talk-au] Mapping easements
There are lots of different types of easements. Other than buried gas pipe lines there are; buried optical fiber lines over head power lines, and access tracks to them public roads through property (farms, State Forests, National Parks etc) private access through one or more properties to another private property old stock routes (the long paddock) .. these can be see on the DCS base map - e.g. Sturt National Park And probably more... The old stock routes cannot be 'seen on the ground'. Yet someone could insist on using it.. they would need permission from IIRC the stock board who usually imposes restrictions - start dates, minimum speed - where stops are made and for how long .. etc. Mapping what you see is fairly safe. Mapping an easement ... ? how wide is it? There would be lots of questions about it .. I'd stay away unless you have a formal source that can easily be checked.
