Hello!I have the following problem; I have points feature class that i created from polygons with their coordinates. I would like to calculate for each point the coordinates of the second point at certain distance and at certain angle from the original point. I managed to calculate the offset values for X and Y but I cannot add those values to original coordinates. I was able to do that in ArcMap 10.1 in edit session using calculate field in table however I cannot get python to do the same thing. Python just rounds up the result despite fact that all fields are float.Here is picture of attribute table where I calculated end_X field with field calculator in ArcMap (that's how I would like the result to loke like) and end_Y field that was calculated using python.[ATTACH=CONFIG]30065[/ATTACH]First I tried to do this using cursors (commented out region), after that I opened edit sesion and used calculate field but that also didn't gave the desired result. Here is the relevant part of code:rows = arcpy.UpdateCursor(depressionsLocation + centerName, "", depressionsLocation + depressionsName.replace('.shp', '.prj'))
for row in rows:
row.disp_X = (sin(float(row.MBG_Orient))*row.MBG_Length)
rows.updateRow(row)
del row, rows
rows = arcpy.UpdateCursor(depressionsLocation + centerName, "", depressionsLocation + depressionsName.replace('.shp', '.prj'))
for row in rows:
row.disp_Y = (cos(float(row.MBG_Orient))*row.MBG_Length)
rows.updateRow(row)
del row, rows
##rows = arcpy.UpdateCursor(depressionsLocation + centerName, "", depressionsLocation + depressionsName.replace('.shp', '.prj'))
##for row in rows:
## row.end_X = (float(row.X)+float(row.disp_X))
## rows.updateRow(row)
##del row, rows
##rows = arcpy.UpdateCursor(depressionsLocation + centerName, "", depressionsLocation + depressionsName.replace('.shp', '.prj'))
##for row in rows:
## row.end_Y = (float(row.Y)+float(row.disp_Y))
## rows.updateRow(row)
##del row, rows
edit = arcpy.da.Editor(depressionsLocation)
# Edit session is started without an undo/redo stack for versioned data
# (for second argument, use False for unversioned data)
edit.startEditing(False, True)
# Start an edit operation
edit.startOperation()
arcpy.CalculateField_management(centerName, "end_X", '!X! + !disp_X!', "PYTHON")
# Stop the edit operation.
edit.stopOperation()
# Stop the edit session and save the changes
edit.stopEditing(True)
