+//The latest build of the Geospatial Plugin can be found at:// https://tiddlywiki5-git-geospatial-plugin-jermolene.vercel.app/plugins/tiddlywiki/geospatial/index.html
+
+!! Introduction
+
+{{$:/plugins/tiddlywiki/geospatial/readme}}
+
+!! Prerequisites
+
+This demo requires that the API keys needed to access external services be obtained by the end user and manually configured. These keys are stored in the browser and so only need to be set up once. See the ''Settings'' tab of [[the plugin|$:/plugins/tiddlywiki/geospatial]] for details.
+
+!! Demos
+
+* Visit the ~GeoFeatures and ~GeoMarkers tabs to see the data loaded into this wiki
+* Click on a link to a layer or marker to open the corresponding tiddler that includes a map
+* Use the Flickr tab to retrieve geotagged photographs from Flickr
+* Visit a ~GeoMarker tiddler and use the "Call ~TravelTime" button to calculate an isochrone from that location using the ~TravelTime API
+

+!!! Photo Tiddlers
+
+The procedures that retrieve photos from Flickr create a separate tiddler for each retrieved photo. The field values of these photo tiddlers are specified through a photo tiddler template that specifies a filter expression for each field that is to be included.
+
+A [[default photo tiddler template|$:/plugins/tiddlywiki/geospatial/procedures/Flickr/DefaultPhotoTemplate]] is used if one is not specified. The default template makes the following assignments:
+
+|!Field |!Description |
+|title |Set to "Flickr Photo " appended with Flickr's ID for the photograph |
+|tags |`$:/tags/GeoMarker` and `$:/tags/FlickrPhoto` |
+|caption |The title of the photograph |
+|lat |The latitude of the image (blank for non-geocoded photographs) |
+|long |The longitude of the image (blank for non-geocoded photographs) |
+|alt |0 |
+|photo-url |The URL of the "large" image size of the photograph (longest side will be a maximum of 1024px) |
+|icon-url |The URL of the "small thumbnail" image size of the photograph (cropped to a square of maximum size 75px)  |
+
+The photo tiddler template can reference the following variables. See [[Flickr's documentation|https://www.flickr.com/services/api/misc.urls.html]] to learn how these values can be combined to construct URLs to access photographs.
+
+|!Variable |!Description |
+|photoData |Raw JSON data returned from Flickr API |
+|photoFarm |Flickr photo farm associated with the photograph |
+|photoServer | Flickr server associated with the photograph |
+|photoID |Flickr photo ID for the photograph |
+|photoSecret |The URL secret associated with the photograph |

+
+The following attributes are supported:
+
+|!Attribute |!Description |
+|''title'' |Optional title of a tiddler that defines the base layer through the fields ''caption'', ''tiles-url'', ''max-zoom'' and ''text'' (the text field defines the attribution string for the base layer) |

+|''tiles-url'' |Optional templated tile server URL for the base layer |
+|''max-zoom'' |Optional maximum zoom level for the base layer |
+|''attribution'' |Optional attribution text for the base layer |
+
+The base layer will only work if all four of the required items ''name'', ''tiles-url'', ''max-zoom'' and ''attribution'' must be provided, either through the base layer tiddler specified in the title attribute, or explicitly via their own attributes.
+
+See https://leaflet-extras.github.io/leaflet-providers/preview/ for a collection of compatible base layers.

+
+The `tm-request-geolocation` message requests the location of the device on which TiddlyWiki is running. Browsers will request permission from the user before returning the location.
+
+The following parameters are supported:
+
+|!Parameters |!Description |
+|''actionsSuccess'' |Action string that is invoked if the request succeeds. See below for the variable values that are made available to the action string  |
+|''actionsError'' |Action string that is invoked if the request fails. See below for the variable values that are made available to the action string |
+|''accuracy'' |Optional value "low" or "high", defaults to "high". Note that higher accuracy can be significantly slower |
+|''timeout'' |Optional timeout value in milliseconds after which requests are automatically aborted. Defaults to infinity, meaning that requests do not timeout |
+|''maximumAge'' |An optional positive value indicating the maximum age in milliseconds of a possible cached position that is acceptable to return. If set to 0, it means that the device cannot use a cached position and must attempt to retrieve the real current position |
+
+The following variables are made available to the action strings passed in the ''actionsSuccess'' parameter:
+
+|!Name |!Description |
+|''timestamp'' |Date and time at which the location was retrieved, in TiddlyWiki YYYYMMDDHHMMSSmmm format |
+|''latitude'' |The latitude of the position in decimal degrees |
+|''longitude'' |The longitude of the position in decimal degrees |
+|''altitude'' |The altitude of the position in meters, relative to sea level. This value can be null if the implementation cannot provide the data |
+|''accuracy'' |A number representing the accuracy of the latitude and longitude properties, expressed in meters |
+|''altitudeAccuracy'' |A number representing the accuracy of the altitude expressed in meters. This value can be null |
+|''heading'' |A number representing the direction towards which the device is facing. This value, specified in degrees, indicates how far off from heading true north the device is. 0 degrees represents true north, and the direction is determined clockwise (which means that east is 90 degrees and west is 270 degrees). If speed is 0, heading is NaN. If the device is unable to provide heading information, this value is null |
+|''speed'' |A number representing the velocity of the device in meters per second. This value can be null |
+
+Note that Safari appears to provide obfuscated values for some items for privacy reasons.

+/**
+ * Convert locations to and from short codes.
+ *
+ * Open Location Codes are short, 10-11 character codes that can be used instead
+ * of street addresses. The codes can be generated and decoded offline, and use
+ * a reduced character set that minimises the chance of codes including words.
+ *
+ * Codes are able to be shortened relative to a nearby location. This means that
+ * in many cases, only four to seven characters of the code are needed.
+ * To recover the original code, the same location is not required, as long as
+ * a nearby location is provided.
+ *
+ * Codes represent rectangular areas rather than points, and the longer the
+ * code, the smaller the area. A 10 character code represents a 13.5x13.5
+ * meter area (at the equator. An 11 character code represents approximately
+ * a 2.8x3.5 meter area.
+ *
+ * Two encoding algorithms are used. The first 10 characters are pairs of
+ * characters, one for latitude and one for longitude, using base 20. Each pair
+ * reduces the area of the code by a factor of 400. Only even code lengths are
+ * sensible, since an odd-numbered length would have sides in a ratio of 20:1.
+ *
+ * At position 11, the algorithm changes so that each character selects one
+ * position from a 4x5 grid. This allows single-character refinements.
+ *
+ * Examples:
+ *
+ *   Encode a location, default accuracy:
+ *   var code = OpenLocationCode.encode(47.365590, 8.524997);
+ *
+ *   Encode a location using one stage of additional refinement:
+ *   var code = OpenLocationCode.encode(47.365590, 8.524997, 11);
+ *
+ *   Decode a full code:
+ *   var coord = OpenLocationCode.decode(code);
+ *   var msg = 'Center is ' + coord.latitudeCenter + ',' + coord.longitudeCenter;
+ *
+ *   Attempt to trim the first characters from a code:
+ *   var shortCode = OpenLocationCode.shorten('8FVC9G8F+6X', 47.5, 8.5);
+ *
+ *   Recover the full code from a short code:
+ *   var code = OpenLocationCode.recoverNearest('9G8F+6X', 47.4, 8.6);
+ *   var code = OpenLocationCode.recoverNearest('8F+6X', 47.4, 8.6);
