I have a lot of MXD (more than 200) and all of them use a polygon shapefile "study_area_v00.shp". Then, just export the event theme to shapefile. Applying the features in the shapefile as a mask on the raster sets all pixels outside of the features to be zero. This tool creates only simple feature classes such as point, multipoint, polygon, and polyline. Transform (coordTrans) # create a new feature outFeature = ogr. Now we have the basis for our shapefile creation with python. Fortunately, there are number of workarounds available to make this happen.

Often times, your shape files or service definitions may not contain the metadata you want to show on the portal item. But to create a shapefile for ArcGIS we will need a so-called driver for this operation as different GIS have different shapefile-definitions. Similar approach can be used to for example to read coordinates from a text file (e.g. Let us take a look at USA COVID-19 data by state.
