Seneca Park mapping. I obtained LIDAR contours and overlaid them onto the existing map from a couple of years ago. In addition to LIDAR, I had parcel boundaries, edge of pavement data, and building footprint data from the county, all processed with Global Mapper into a form that OCAD can use. Plus the most recent aerial photos, in jp2 format, which Global Mapper processes.
The problem, of course, with simply overlaying new, more accurate, contours onto the old map is that a lot of features on the old map were put on the map relative to the imperfect contours from the USGS map. A stream would be drawn down the center of a reentrant, for example. When the contours move somewhat, to be more accurate, there are lots of features that need to be checked out and possibly moved. The stream down a reentrant is an easy fix -- if the stream is now along the side of a reentrant rather than in the center, it's pretty obvious it needs to be moved. A lot of other things aren't so obvious and therefore need to be checked out.
Also, I'm attempting to do the map to ISSOM mapping standards, since it will probably almost always be used for a sprint, whenever it is used (and it's on the schedule for this year).
