Sartopo / 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.
Major release. 41 issues closed since v1.1.2 (June 2, 2020), inclung many major bug fixes, and many API enhancements. Check the GitHub repository for documentation updates. Click Here to see the full list of issues closed since v1.1.2.
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.
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.
pip install sartopo_python
domainAndPort="localhost:8080" ('sartopo.com' will require signed requests - see details below)
mapID=None - three- or four-character map ID [required]
configPath=None - only needed for signed requests
account=None - only needed for signed requests
id=None - only needed for signed requests
key=None - only needed for signed requests
sync=True - if True, the session will automatically sync at the specified interval, so .mapData will be kept up to date
NOTE: the following arguments are only relevant if sync=True
syncInterval=5 - interval (in seconds) between automatic sync requests
syncTimeout=2 - time after which an error will be thrown if no response is received
syncDumpFile=None - file to which all sync activity will be logged
propUpdateCallback=None - callback function to be called whenever a feature's properties have been changed
geometryUpdateCallback=None - callback function to be called whenever a feature's geometry has been changed
newObjectCallback=None - callback function to be called whenever a new feature has been added
deletedObjectCallback=None - callback function to be called whenever a feature has been deleted
For the following geometry operations, the arguments can be title (string), id (string), or feature (json)
Also, the arguments can refer either to assignments or to non-assignment objects.

Requests to localhost do not require any authentication; requests to sartopo.com do require authentication in the form of request signatures.
If the sartopo session object was created with 'sartopo.com' as part of the URL, then this module will sign all requests before sending.
Authenticaion information required to generate the signed requests includes a request expiration timestamp (just a couple minutes in the future is fine), a public key, and an ID code. For a good explanation of how to determine those three items, see the README at https://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_python 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=1234567890
An 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.
