From looking at the data, the 181 points need to have longitude as negative values. Another thing I notice is that these sets of points are from distinct areas - are they supposed to be? 43.45, -70.38 typical in the 134 file, 43.27, -70.23 typical in the 181 file. ... View more

Hi Brian, Can I ask what coordinate system the points from excel are in?  Ie/ are they Lat/Long values or UTM coordinates? It is very important to know what system the coordinates were recorded as. If they are Lat/Long, try to make sure that all points are in the same format ie/ decimal degree. Also make sure that (assuming you are in the US) the longitude value is negative and the latitude positive. After you've made sure of these and at least some of the points don't line up then you don't have the correct information for how they were entered into excel. If some points line up where they should be and some don't, that is an error where different points were recorded differently (ie/ decimal degree compared to decimal minute) but entered as if they were recorded the same. The first thing I would say is to know what a typical coordinate is for your study area (from other data or google earth). This is a quick way to see if your data makes sense in excel. ... View more

Thanks a lot for the reply Bond.  I ended up doing something similar yesterday with just setting an 'offset' distance from each start point to the waterline and adding them (sometimes negative) to the points along each line that had 'distance along line' with associated elevation values. Then exported the dbase table to excel for the better graphing options.  Attached is a quick example.  Thanks again! ... View more

And on the opposite side of the coin, allow  users to increase the size of this list to include more projects than the default number.  Very helpful for those that work on multiple projects at a time and want quick access to the exact projects that were most recently worked on. ... View more

Thanks for the replies Hardolf/Theodore, I ended up assuming that the quarry face was a straight line and then used the known expansion area (acres) to determine what distance to buffer each successive line radially.  Because I didn't need to be perfect I grouped together 3 to 4 years worth of expansion in each buffer set as the difference between their ideal buffers in linear distance was < 1ft.  As you mentioned I would then trim the ends and recalculate buffers.  A little time consuming but it worked in this instance! ...
