Yes, this is possible using ShapeFileFeatureTable. You can use the AddFeatureAsync (or AddFeaturesAsync) method to add new features, UpdateFeatureAsync (or UpdateFeaturesAsync) to update existing features, or DeleteFeatureAsync (or DeleteFeaturesAsync) to delete existing features. Here's a quick example of adding new features: // Create the shapefile table, specifying the path to the shapefile var shapefile = new ShapefileFeatureTable(filePath); // The shapefile must be loaded to perform operations on it await shapefile.LoadAsync(); // Create the feature, specyfing the new feature's attributes and geometry var feature = shapefile.CreateFeature(attributes, geometry); // Add the newly created feature to the shapefile await shapefile.AddFeatureAsync(feature);‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ And editing existing features: // Create the shapefile table, specifying the path to the shapefile var shapefile = new ShapefileFeatureTable(filePath); // The shapefile must be loaded to perform operations on it await shapefile.LoadAsync(); // Create the feature, specyfing the new feature's attributes and geometry var feature = shapefile.CreateFeature(attributes, geometry); // Add the newly created feature to the shapefile await shapefile.AddFeatureAsync(feature);‍‍‍‍‍‍‍‍‍‍‍ // Query the shapefile to retrieve the feature or features to edit. The query // parameters can specify object IDs, attribute values, search geometries, and more var queryResult = await shapefile.QueryFeaturesAsync(queryParameters); // For this example, just get the first feature from the result var feature = queryResult.First(); // Update the feature's geometry feature.Geometry = newGeometry; // Update attribute values. Note that the type of the new value must match the type // of the attribute field being updated (e.g. string, integer, date/time, etc) feature.Attributes["SomeStringFieldName"] = "New attribute value!"; feature.Attributes["SomeDateFieldName"] = DateTimeOffset.UtcNow; // Apply the edits to the shapefile await shapefile.UpdateFeatureAsync(feature); ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Hope this helps.
