I'm a Master's student in oceanography research and I'm using the latest version of ArcGIS Pro. I am using data from the Canadian Ice Service Arctic Regional Sea Ice Charts in SIGRID-3 Format, Version 1. This type of data is based on a shapefile (.shp) format to store the shape geometry, this file is accompanied by an index file (.shx), there is a database file (.dbf) to store all the shape attributes in the main file, then there is an XML file (.xml) for the metadata related to each ice chart. This metadata includes projection, location, keywords and contact information. Since 2006, the Canadian Ice Service's ice charts have been made up of several different colored polygons (MMO) for different ice concentrations (CT = Concentration Total). However, when I open the shapefile (.shp) on ArcGIS Pro, the polygons are not displayed. I can open the shapefile as shown in the image below (figure 1 = What I see). The information is present when I touch a spot on the map, but I can't see the different-colored polygons as in the second figure (figure 2 = What I'd like to see). I can't find this information anywhere. Do you know how to help me, or do you know someone who does, please? Do you think that my version of ArcGIS Pro is too recent for this type of data?
Sounds like you just need to update the symbology. You can see if there's a .lyr or .lyrx file available (and then use it to run Apply Symbology from Layer), or you can do it manually.
- Open the Symbology pane (you can find it under the View tab).
- Under Primary symbology select Unique Values, and then select the CT field in the Field 1 dropdown.
- Apply colors based on the version you show in ArcMap.
