Package: sartopo-python
sartopo_pythonSartopo / Caltopo currently does not have a publically available API;
this code calls the non-publicized API that could change at any time.This module is intended to provide a simple, API-version-agnostic sartopo
interface to other appliactions.This python code is in no way supported or maintained by caltopo LLC
or the authors of caltopo.com or sartopo.com.New for v1.1.0. 5-30-2020:Signed requests for online maps are now supported.  The same requests that work here for offline maps are now also working for online maps.  See the signed request explanation at the bottom of this README file.New for v1.0.6 3-30-2020:getFeatures now returns the entire json object for each feature.  The top level keys should be id, geometry, and properties.  This allows preservation of things like marker-symbol, folder, coordinates, and so on when moving an existing marker.Installation:pip install sartopo_pythonProvided functions in class SartopoSession:__init__ - create a new sessiondomainAndPort="localhost:8080"mapID[required]=NoneThe remaining arguments are only needed to generate signed requests for online maps at sartopo.com; see the signed request explanation at the bottom of this README file.configpathaccountidkeyexpiresgetFeatures - get a list of map featuresfeatureClass=None - "Marker" etc to return only markerssince=0 - get features only since this timestampaddFolder - create a SARTopo folderlabel="New Folder"addMarker - create a SARTopo markerlatlontitle="New Marker"description=""color="FF0000"symbol="point"rotation=NonefolderId=None(beginning in 1.0.4) existingId="" - specify this to edit an existing markerEXAMPLES:#     from sartopo_python import SartopoSession

For a good explanation of how to determine those three items, see the README athttps://github.com/elliottshane/sme-sartopo-mapsrv.Once those three items are determined, they should be stored in a configparser-compatible file that should look like the following:# sartopo_pyhton config file
# This file contains credentials used to send API map requests
#  to sartopo.com.  Protect and do not distribute these credentials.

[myaccount@gmail.com]
id=123456ABCDEF
key=aBcDeF12345somepublickey
expires=1234567890An explanation of how the SartopoSession constructor arguments are used to determine credentials, if sartopo.com is in the URL:# if configpath and account are specified,
   #  conigpath must be the full pathname of a configparser-compliant
   #  config file, and account must be the name of a section within it,
   #  containing keys 'id', 'key', and 'expires'.
   # otherwise, those parameters must have been specified in this object's
   #  constructor.
   # if both are specified, first the config section is read and then
   #  any parameters of this object are used to override the config file
   #  values.
   # if any of those three values are still not specified, abort.
