Sally StrangeI went and did a Solstice survey, but now I can't get the data off the data collection device. Worried I may have accidentally deleted it and will need to do another survey. I worried about this last time I did a survey and it wasn't the case, but I can't help freaking out a bit. Especially since the guy who helped me last time is out in the field right now. /grump<a href="https://eldritch.cafe/tags/surveying" class="mention hashtag" rel="nofollow noopener" target="_blank">#surveying</a> <a href="https://eldritch.cafe/tags/CAD" class="mention hashtag" rel="nofollow noopener" target="_blank">#CAD</a> <a href="https://eldritch.cafe/tags/arcGIS" class="mention hashtag" rel="nofollow noopener" target="_blank">#arcGIS</a> <a href="https://eldritch.cafe/tags/Civil3D" class="mention hashtag" rel="nofollow noopener" target="_blank">#Civil3D</a>
