I have collected GPS points along the road. and got Right angle Tape measurements of Boundary walls and other objects from that respective points. I have those records in Excel Sheet and GPS observation is in Shp file. Now I want to plot those points. I Have Tried with Linear referencing Tool in Arcmap. The events were created as point layer but that is not in Right Angle... How to Solve this?
You can get the normal angle or tangent angle or the compliment to either of those angles for any point event along a Route. You can then use the Bearing and Distance to Line tool to set lines extending from your event on that angle bearing and extract the To End Point of the line with the Feature Vertices to Point tool to get a new point. If you just want to follow the road a certain distance from your original point event, you just add or subtract the distance you want to offset from the original point measure to move that distance up or down the road (as long as the measure stays within the measure range of the route). The optional Side Offset field value can also offset a point event left or right of a line as a starting point using a positive or negative side distance number. So all forms of Right angles and Normal angles and road following and road offsets are possible with LR and possibly a couple tools from the Feature toolset. So please clarify your goal better.
