<p dir="ltr">I can answer that one, at least based on the first year the project was taking coordinates for the Firehole Geyser Basins. The SCA techs that year, especially early on, were much shyer about getting close to the features than they needed to be, and no policy had been laid out by project management on where to take coordinates for large or genuinely unapproachable features.</p> <p dir="ltr">As a result, many of the coordinates that year were only taken within roughly the same long-distance dialing area as the feature being mapped. Obviously, it doesn't matter how accurately the equipment pinpoints your location if you're not particularly close to what you're trying to map.</p> <p dir="ltr">It also wouldn't surprise me if some mislabeling or shuffling happened, especially in dense areas like Geyser Creek or Geyser Hill.</p> <p dir="ltr">David Schwarz</p> <div class="gmail_quote">On Nov 10, 2013 8:31 PM, "Udo Freund" <<a href="mailto:udofreund317@gmail.com">udofreund317@gmail.com</a>> wrote:<br type="attribution"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <p dir="ltr">Forgot to mention that Yellowstone has had some earthquakes that might cause things to actually move around over the course of several years since GIS surveys were done.</p> <p dir="ltr">Thanks,<br> Udo Freund</p> <div class="gmail_quote">On Nov 9, 2013 5:21 PM, "Will Boekel" <<a href="mailto:wolveslax65@comcast.net" target="_blank">wolveslax65@comcast.net</a>> wrote:<br type="attribution"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div dir="ltr"> <div dir="ltr"> <div style="font-size:12pt;font-family:'Calibri'"> <div>Scott,</div> <div> </div> <div>Thanks for the advice about using the RCN data. I have been using that resource and it has been very helpful most of the time. However many of the coordinates in their database are a bit off and most of the pictures are of the geyser’s vent and not a location photo. In an area that has a few geysers all within a few feet of each other it is sometimes hard to figure out where the slightly off RCN marker belongs (I have had cases where the marker was pretty much equidistant from 3 holes and I had no idea which one it belonged to).</div> <div> </div> <div>Thank you for the help,</div> <div> </div> <div>Will Boekel</div></div></div></div> <br>_______________________________________________<br> Geysers mailing list<br> <a href="mailto:Geysers@lists.wallawalla.edu" target="_blank">Geysers@lists.wallawalla.edu</a><br> <a href="https://lists.wallawalla.edu/mailman/listinfo/geysers" target="_blank">https://lists.wallawalla.edu/mailman/listinfo/geysers</a><br></blockquote></div> <br>_______________________________________________<br> Geysers mailing list<br> <a href="mailto:Geysers@lists.wallawalla.edu">Geysers@lists.wallawalla.edu</a><br> <a href="https://lists.wallawalla.edu/mailman/listinfo/geysers" target="_blank">https://lists.wallawalla.edu/mailman/listinfo/geysers</a><br></blockquote></div>
