Hi, colleagues,
I am learning the ArcGIS spatial analyst. I have some problems. My questions are listed as below.
1. What is the difference between the layer file with ???end to end blue arrows??? icon and the the layer file with the yellow diamond icon?
2. What is the format of the layer files with ???end to end blue arrows??? icon?
3. Is the format of the layer files with a yellow diamond icon .lyr?
4. Should I select the layer file (e.g. elevation) with ???end to end blue arrows??? icon or layer file with yellow diamond icon?
5. I would like to calculate the least cost distances (LCD) between more than two points, however the ???Spatial Analyst Tutorial??? provides the workflow for only two points (the final site and destination in Stowe.gdb). Can you tell me the complete workflow for calculating the LCDs among more than two points (see, among the five schools in the tutorial)?
Attached please find the model I made.
Thanks
