Need help - Line Density Tool conversion of units

[Daniel2]

Hi! So I'm currently working on my Bachelor Thesis and I used theLine Density Tool(In ArcGIS Pro) to measure the density of Bikelanes in squaremeters. However in the Paper i based my method on they used "Math tools" to converse the given output raster fromsquare meterstometers of Bikelane per square meter.I've been breaking my head about this and I just can't find the formula to calculate it like that.
Which Math Tool can I use to calculate that and what would the formula be? To Anybody who knows how that works thanks in advanced and you'll be my rescue.
Thanks!

You'd really need to consider you search radius, and work backwards from the area of the circle of that radius and the length of the bike lanes within it.

is this metres of bike lane per sq metre of a larger aggregation area? If you have larger defined aggregation areas you may want to do something like a Spatial Joinhttps://pro.arcgis.com/en/pro-app/latest/tool-reference/analysis/spatial-join.htmand summing the length attribute in the field mapping, orhttps://pro.arcgis.com/en/pro-app/latest/tool-reference/analysis/tabulate-intersection.htm

Agreed with Daniel, you need to readhttps://pro.arcgis.com/en/pro-app/latest/tool-reference/spatial-analyst/how-line-density-works.htm

The line density is to calculate the length of some lines in a certain area (it is a circle now). So the unit is the length of lines per area, which could be meter/square meter or inch/square meter or meter/square inch. I guess if you see the unit is square meter only, it might represent the count of lines per area. Then, they calculated the length of each line in meter.

Thanks for the answers! I think I was just confused by the methodology in the papers.
