Hello everyone and welcome back to TGI5.

Today's episode is going to cover sector mapping within ArcGIS. Now sector mapping is the process of creating a visualization for the cell sectors on a cell site antenna. And within ArcGIS Pro, there is a tool that allows you to create these cells sector visuals from a spreadsheet, or a feature class, or shapefile that you have that contains the information about those cells sectors. So, let's Jump Right In and show how we can run this tool with in ArcGIS Pro. So the first thing that I want to do is add a spreadsheet of those antennas. So, here is that table, and we'll go ahead and open up the attribute table. We can see what is within this spreadsheet. Now, the schema that we see here is coming directly from our Communications Data Management for ArcGIS Enterprise data model, and we've just populated this with some antenna information. So we can see information on the antenna like the Site ID, the Sector Number, the frequency or the band for that particular antenna, as well as the lat/long of the actual cell site.

Now, under the geoprocessing panel, if we do a search, or we go to the crime analysis and safety tools Toolbox will notice this cell site records to feature class tool. This is the tool that we will use to generate those cell site sector visuals. So we'll choose our antennas table. And then we'll decide where to save the output feature class. Now, there are two layers that get created. There is a antenna sites layer, so it will create a point feature class for the actual cell site. And then there is a an antenna sector feature class that will contain the polygon visual for the sectors. Then within this tool will need to fill out some additional information. Like the Site ID field, as well as the Sector ID field within our spreadsheet, will fill out the lat and long fields so that we can geocode and plot the cell site locations. As well as some important fields here, like the Azimuth field and we can always set a default if we don't have the Azimuth in our data, we need to fill out the beamwidth field and we can choose if it's a full beamwidth, or a halfbeam width, and then finally, the radius field. So these are all fields that have been pre-populated in our spreadsheet and as we run this tool, it will actually create those cell site locations as well as that sector visual.

Now as this tool finishes up will start to see the cell site locations, draw on the map and over in our table of contents. We also see the site and sector layers, so let's open up our Antenna sites layer here and just take a look at the attribution that is a part of this layer. So, all of those input parameters that we filled out in the tool, get populated into fields here and then it brings over some information from our original spreadsheet. And if we open up the sectors table, same thing, the input parameters get carried over as well as that attribute information from our original antenna spreadsheet. Now let's zoom in on this data a little bit closer. We zoom into our cell sites and now we start to see those sector visual polygons. We'll select one of them here and then we'll take a look at the attributes for this particular sector. So as we can see, this geoprocessing tool within ArcGIS Pro very quickly created our cell site sector visuals from that original spreadsheet.

Now, if you would like to test this out, this is a part of ArcGIS Pro 2.7 or later. And you'll be able to access that geoprocessing tool. And if you've got a spreadsheet with that cell sector or antenna information you can bring that right in and line up your fields as you configure the tool and run it.

This has been another episode of TGI5, thank you all for joining us and we'll see you next time.
