Numerous papers talk about creating latilong or lat/long blocks of 1 degree or 2 degrees. Is there a way to do this in ArcGIS? We have nest location data for three species of shorebirds in six states of the US, as well as the location and data for all the weather stations in those six states. We would like to find average temperature during the breeding season in those six states and see if changes in average temperature are correlated with changes in clutch initiation date in the shorebird species. One way we can do this (according to previous studies) is to create latilong blocks and use the data from the weather stations in those blocks where our nests are located. However, we are unfamiliar with how to do this in ArcGIS or if there is another way to do it. Any suggestions are much appreciated!
