I have both TINs and LiDAR data for an entire county, divided into a grid of multiple tiles. I want to generate contours from this data at 2 foot intervals, using ArcGIS 10.5.
I decided to do this by first generating an elevation raster using TIN to Raster, and then running the Contour tool to create contours from the raster.
The problem is that the resulting contours have a gap where the tiles meet. The width of the gap is equal to the cell size I specify when creating the raster.
How can I eliminate this gap and get contours that are seamless across tiles?
Would it be better to start with the LIDAR data instead, or would I still encounter a similar problem?
