The last time I was in the office tracing, I noticed that some of the parks were harder to trace than others, for different reasons. There were some parks that the drawn maps just didn’t line up well enough to the GIS map and some that I couldn’t reference well due to tree cover.
So, the past couple weeks I’ve been going out to the different parks to take GPS reference points to be able to georeference the drawn maps more accurately. I was able to do this for some of the maps. However, there are 2 parks whose drawn maps don’t seem to match what is actually in the parks or what I have on the basemap.
For Shale Hollow park, I believe this is due to the park only just opening during the time when the basemap image was taken, so the difference in basemap and what I had seen in the park threw me off. I’m going to go back to the park to take more accurate GPS points so that I can overlay the drawn map even without matching it to the basemap image.
For the Emily Traphagen park, the drawn map definitely doesn’t match what was actually done in the park. However, the main differences don’t relate to the utility lines, so I’m going to return and double check to see if the utility lines can still be used in the map.
I don’t have a drawn utility map for Hogback ridge park, so I’ll have to use the line locator if I want to trace those lines.
I worked on tracing the utilities for all the other parks this week in the office.
