That *is* what I needed.  Apparently you cannot assign it to a variable, which (mistakenly) led me to believe that approach was out of date.  Really what I needed is: df = pandas.DataFrame(_layer.query().sdf) And now I have that -- thanks! ... View more

I downgraded to 0.23.4, but it did not solve the problem.  pandas.DataFrame.spatial does not seem to have a method .from_layer, at least not according to tab-complete.  (using arcgis 1.6) ... View more

The process is quite straightforward in Raster Calculator, but if you have already committed to the Composite Bands/Mosaic Dataset/Image Analysis window, it is completely opaque.  Raster Calculator doesn't work in that context, and while there are functions for "Apparent Reflectance" and -- inexplicably -- "Sentinel 1 Radiometric Calibration," it's not at all clear how one would put together such a function for Landsat.   ...

Much stripped down, this works: my_line_geom = {'paths' : [[[-78.8,38.8],[-78.8,38.2]]]} my_line = arcgis.geometry.Polyline(my_line_geom) my_line_feature = arcgis.features.Feature(my_line) my_line_feature_set = arcgis.features.FeatureSet([my_line_feature]) map1 = gis.map('Orkney Springs') map1.draw(my_line_feature_set) map1 I have not been able to draw both features of a two-feature feature set.  Only the second one shows up.  Nor have I had any success setting the symbology. ...

If you actually have a polyline geometry, try following it with lines = arcgis.features.Feature(fc_lines) lines1 = arcgis.features.FeatureSet([lines]) and then map1.draw(lines1) instead of add_layer. If not, to get from the text string to a geometry, you'd need fc_lines = arcgis.geometry.Polyline(fc_string_thing) before all that.  Hope this works; I got it working for pandas-dataframe-to-polygon.  ...

Thanks Rohit.  I had tried converting it to a Layer, but I overlooked FeatureSet.  It works! ... View more

I am able to produce: so to the best of my knowledge, I am authenticated.  I have also been able to display maps.  The specific line giving the no-spatial-analysis error is: PlotDiscs = create_buffers(PlotPoints, [11.2838], None, 'Meters', output_name='PlotDiscs400m') where PlotPoints is PlotPoints also displays as it ought to on the map. ps -- changing the url from the one they gave me when I signed up for a developer account to arcgis.com as your link instructs for an organization makes no difference.  I am part of an organization, but I signed up as an individual, and we haven't yet connected me to them.

"item" seems a little vague.  I can, for example, add_layer a set of points: df1 = pandas.read_csv('CTpolygon.csv', header=0, names=['longitude', 'latitude']) rows = np.random.choice(df1.index.values, 499) df = df1.ix[rows] CTpoints = gis.content.import_data(df) map1 = gis.map('Connecticut') # focus on CT                    map1.basemap = 'topo' map1.add_layer(CTpoints) map1 How is a polygon feature any different in terms of being an "item"?   ...
