What is Z factor in Arcgis?
The z-factor is a conversion factor that adjusts the units of measure for the vertical (or elevation) units when they are different from the horizontal coordinate (x,y) units of the input surface. It is the number of ground x,y units in one surface z-unit.
Why can’t I calculate geometry in ArcMap?
If you are working in a geographic coordinate system, you will not be able to calculate geometry. The calculate area and perimeter options will be disabled. ArcGIS uses planimetric algorithms to calculate geometry such as area and perimeter. To be able to calculate area, you will need to work with projected GIS data.
How do you calculate geometry in Arcpro?

What is the m value in Arcgis?
The m-value field is a property of a feature class that is enabled when a feature class is initially created. Linear referencing systems (LRS) use routes, created as PolylineZM features with m-values, to model linear distances and related events independent of the line geometry.
