Working with Attribute Data
Working with Attribute Data using the FAA Airman Database This post will incorporate the FAA Airman Database and understanding how tables can be joined using common fields. By using table joins, we will perform attribute based queries and generate new feature classes with those queries. When we first open the data in ArcGIS Pro, there are 4 different features: airman_pts_count_us Fishnet_10km_cont_us us_zipcode_cont continental_us_counties_lambert Figure 84: Four Different Features Now if we look at the projection information for each of these features, we can see that a couple of them are different. airman_pts_count_us: WGS_1984 Fishnet_10km_cont_us: GCS_1983 us_zipcode_cont: Lambert continental_us_counties_lambert: Lambert Projections are a mathematical transformation that takes latitude and longitude coordinates and transform them to an XY coordinate system. This helps you to create a map that accurately shows distances, areas, or ...
