![]() ![]() Make sure that the coordinate system is set to “GCS_WGS_1984” for the new feature layer showing the postal codes. Use the parameters specified in the image below to make sure you get the X and Y values correctly: Figure 2: The XY Table to Point Tool Parameters Next, the “XY Table to Point” tool window will open, where you will need to specify the input table name and the column names for the x and y coordinate values. This is done by choosing “Map” on the ribbon interface, selecting “Add Data” and “XY Point Data” from the dropdown list. csv file, you can draw the postal codes on the map inside ArcGIS Pro. STEP 2: Add the data to the map window in Pro We also know that the data belong to the UK, so when displayed inside Pro, it should line up with the UK basemap. ![]() Luckily, the data has been projected so that Pro won’t have trouble displaying it on a map. These numbers are in decimal degrees format and range from -90 to 90 for latitude and -180 to 180 for longitude. To do this, open the postcodes_meta.csv file that comes with the data download and notice that columns 8 and 9 contain x and y coordinates in WGS84 geographic projection: Figure 1: The metadata file has definitions for each data columnĪ simple Google search for “lat lon values” will tell you that latitude and longitude are a pair of numbers (coordinates) used to describe a position on the plane of a geographic coordinate system. We will do this in Step 2.īefore drawing the postal codes to the map, it is recommendable to look up the metadata file that tells you what the different columns in your dataset represent. Next, drag the postcodes_data.csv file to the map window, so that it is listed in the Contents pane, but not on the map. Download the table to your hard drive, add a folder connection inside ArcGIS Pro through the Catalog window to access the dataset. csv file that contains all UK postal codes and the total persons recorded in that postcode, among others. We’ll be using the UK 2011 census Postcode Headcounts and Households dataset, a very large. We’ll now need to download the spatial dataset for this tutorial. Open ArcGIS Pro and create a new, empty project. STEP 1: Download and examine the (meta)data
