I'm hoping this is a straightforward question to answer!
I am trying to do a hotspot analysis for a dataset of road accidents. I am using the OpenStreetMap as a basemap, and originally imported my dataset with the geographic coordinate system WGS 1984. However when I tried to perform hotspot analysis, it didn't work and told me that "the input feature class does not appear to contain projected data". So, I imported my data again using the projected coordinate system, World>WGS1984 Web Mercator (I didn't know which WGS 1984 to choose, there were a few!). However my data points now show that they are in Nigeria, not Scotland!
If anyone could help I would appreciate it so much, it is for my dissertation and I've been trying to figure out how to use hotspot analysis for months!
p.s. I'm using ArcMap 10
