Use the Project tool to apply a projection to your layer. The projection will have a linear unit (e.g. metres) associated with it. When you rerun Point Distance, the units will be in the linear unit of the input feature class. ... View more

Here's a script that should do what you're after: >>> newLines = [] ... points = "grid_label" ... angleField = "OID" ... lineLength = 300 ... sr = arcpy.Describe(points).spatialReference ... with arcpy.da.SearchCursor(points,["SHAPE@",angleField],spatial_reference=sr) as cursor: ...     for row in cursor: ...         x1 = row[0].centroid.X + (math.sin(math.radians(row[1]))*(lineLength/2)) ...         y1 = row[0].centroid.Y + (math.cos(math.radians(row[1]))*(lineLength/2)) ...         x2 = row[0].centroid.X - (math.sin(math.radians(row[1]))*(lineLength/2)) ...         y2 = row[0].centroid.Y - (math.cos(math.radians(row[1]))*(lineLength/2)) ...         newLine = arcpy.Polyline(arcpy.Array([arcpy.Point(x1,y1),arcpy.Point(x2,y2)]),sr) ...         newLines.append(newLine) ... arcpy.CopyFeatures_management(newLines,r'in_memory\lines') ...

Oh, you've listed 'SHAPE@XY' (itself a tuple), inside another tuple. Try: cursor.insertRow(((x,y))) ... or remove the parentheses around 'SHAPE@XY'. ... View more

You need to fill the fields passed in the cursor initiation statement. Because SHAPE@XY is tuple, you must fill that tuple when you call insertRow. See the second code sample here. with arcpy.da.InsertCursor(An,('SHAPE@XY')) as cursor:     cursor.insertRow( (x,y) ) As a side question, how are you planning to capture a click event as text? Is this a Python add-in? It may be possible, I've just never seen this. ... View more

In that case, quite different description than the original btw, you should look into Zonal Statistics, SUM. You may find it easier to create a new raster with absolute values of biomass per pixel, rather than adding biomass per acre, but it's up to you. ... View more

Have you identified the rock outcroppings in your image? If not, is it an RGB or multispectral image? If multispectral (or even RGB, potentially) start here for more information about image classification. I assume you'll want to go with supervised classification (i.e. draw some training polygons around known rock outcroppings, then extrapolate those spectral signatures to the rest of your image). Once you've identified the outcroppings, run Region Group to identify distinct outcroppings. Then, convert the grouped outroppings raster to polygon. Finally, run the Near tool to get the distance from each outcropping to the next nearest outcropping (requires advanced license). ... View more

Hmmm. Is this in the right place? ... View more

The arguments for AddField are, (in_table, field_name, field_type), in that order. Check syntax section here. arcpy.AddField_management(fc, row[0], fieldtypes[row[1][:4]]) fc = the input table row[0] = the field name (the first column in your spreadsheet. E.g. 'geodb_oid') row[1][:4] = the first four characters of the second column in your spreadsheet (e.g. 'inte') fieldtypes[row[1][:4]] = the value associated with the key 'inte' (e.g. 'LONG') ...

I believe Tabulate Area will do this for you. ... View more

Ah, this one's easy. Python is case sensitive - it should be AddField, not Addfield. ... View more

I was being kind of lazy making the dictionary because I wasn't quite sure how your data looked. fieldtypes[row[1][:4]] ...means: take the first four letters of the value in row[1], find the dictionary key that matches that value, and return the value at that key in the dictionary. Since there is no such value in your dictionary, it returns an error. When I made the example dictionary, I shortened the dictionary keys to four letters ("integer" became "inte") so there would be matches. ... View more

Can you use, and do you get the same error with CopyFeatures_management rather than Copy_management? ... View more

Try adding a second Parse Path tool to the Name variable, set to Path, and named "PATH". Then, change your Clip tool to look for: %PATH%/%FILENAME%.shp ... View more
