What are the actual values of a location and for what location? 2 km is a big difference. 200m would suggest a datum difference, What other coordinate systems are used in your area? I have run out of ideas... what does your associate say?

Near will give you the distance from the line. Unless you replicated all the street nuances (aka curves) and intersections, your streets generated from your observations may or may not be a good representation of existing conditions. Perhaps you can share a typical sample of the existing network and your point locations before you spend a lot of time generating output.

You might want to look at these as well... it will save you connecting the points if you are only interested in "how close" the data are representing the actual locations. Generate Near Table—Help | Documentation Near—Help | Documentation Spatial Join—Help | Documentation

Maria Manz Use None if no item or special value will be used and each feature will be counted once. cell size .... 0.1688... method ... planar I think that your coordinates are in decimal degrees? Right? if so is your study area huge? like 42 degrees high and/or wide? (1/250 of the width or height is the default cell size in the units of the data) Why don't you want to specify a search radius? was this agreed upon? or is this an R default that you are emulating? Think about this. Do you see clusters in the points? In what sort of radius are the clusters? method... use geodesic and revisit your cell size choice, especially if your points are clustered into groupings smaller than your cell size It is hard to make any other recommendations without the "end goal" being known, especially if this goes beyond a pretty map and you need to make inferences about the population patterns. So, you can get a map, it will represent 'density per unit area' but the details still depend on the choices made. If you have a license for An overview of the Spatial Statistics toolbox—ArcGIS Pro | Documentation there are other tools there for mapping and examining patterns (ellipse pattern) and clusters or An overview of the Geostatistical Analyst toolbox—Help | Documentation if you are looking at a predictive surface. So many decisions eh ?

hmmmm I would have to throw in a select by attribute into the mix then to query by the primary column, then aggregate the results later. I won't get to that for a while, but if you had only a few cases of the parcel column, that would be the procedure...get the individual ranked listings, then merge them together.

it might help if you had an image of your input points and the options that you specified in the KD tool. In short, you have observations of something in space... a sample effectively. What you are trying to do is represent the "density" of those points with respect to the other points and a distance for each cell. Each cell in the resultant raster is needs a value which is calculated as follows: Kernel density spreads the known quantity of the population for each point out from the point location. The resulting surfaces surrounding each point in kernel density are based on a quadratic formula with the highest value at the center of the surface (the point location) and tapering to zero at the search radius distance. For each output cell, the total number of the accumulated intersections of the individual spread surfaces is calculated. From Differences between point, line, and kernel density—Help | Documentation So it important to know the cell size and many other parameters that are specified in the tool Kernel Density—Help | Documentation In the end the result is a measure of the number of occurrences of something per unit area. If you change the parameters, keeping the data set the same, you will conceivably get a different result

You have to do this through conda... If you are familiar with it... dry run, check, if ok, remove the dry-run --no-pin is to remove esri's parental controls # ---- first do a dry run to see what is going to happen
conda install fiona=1.18.4 --no-pin --dry-run
# ---- Then if everything looks fine,
conda install fiona=1.18.4 --no-pin

The link table may have been made in the coordinate system of the map and not the data, hence, they could be different. Worth a check on the values of the link table and how the coordinates are defined and whether they are correct

I would recheck the documentation Install and set up | ArcGIS for Developers and specifically here System requirements | ArcGIS for Developers There is no requirement to have Pro installed... as per the note Note: if arcpy is found in the current python environment, it may be used in various locations. Otherwise, pyshp will be used. See SpatialDataFrame for more information. There are python IDEs for linux
