<p>Map Posts allows you to add location as post metadata and insert a map directly in the post, without ever leaving the editor.<br />
No plugin configuration is required; simply install, activate and within the post editor define a location and insert a map.</p>
<h4>WordPress 5.0 and Gutenberg Compatibility</h4>
<p>Map Posts Free, as of version 1.2.2, works best with the Classic Editor enabled (meaning the Classic Editor plugin has been installed<br />
and activated). It will also work with the Gutenberg editor, with the exceptions noted below. Map Post shortcodes can be<br />
added in any block that allows text to be manually typed in; Map Post map insertion buttons are available if a classic editor block<br />
is added (in Gutenberg editor click Add (block); scroll down to Formatting tab and expand; select the Classic block).</p>
<h4>Post Map</h4>
<p>There are 2 types of map that can be inserted. The first (Post Map) displays only one marker, which is the current location<br />
associated with the post. Note that Map Posts automatically adds a location to every post, defaulting to co-ordinates of 0.00,<br />
0.00 (the intersection of the Equator and the prime meridian). Post Maps are typically inserted to display<br />
a location that is related to the post.</p>
<p>To actually insert the map, there are two options. If using the visual editor (or Classic Block), simply place the cursor in the<br />
content area where you would like to insert the map, then click the Insert Post Map button. Alternatively you can simply type in the<br />
Post Map shortcode, which is <strong>postmap</strong>. The second option can be done in visual or text editor mode.</p>
<h4>All Posts Map</h4>
<p>The second type of map is called the All Posts Map. This map inserts a marker for every post that is published (not saved as<br />
a draft) and has a custom location (it has co-ordinates other then 0.00,0.00). Insert this map if you want to display<br />
all post locations in relation to one another.</p>
<p>To actually insert the map, either use the Insert All Posts Map button from the visual editor toolbar, or type in the<br />
shortcode <strong>allpostmap</strong>  (in either visual or text editor mode).</p>
<h4>Adding Location</h4>
<p>To update the location, find the Define Map configuration panel within the post editor and expand it if necessary. If it is<br />
not visible open the WordPress editor screen options and ensure Define Map is listed and is checked.</p>
<p>Locations can be updated by:</p>
<ul>
<li>Clicking on Map</li>
<li>Dragging the Marker</li>
<li>Typing in the Latitude and Longitude Manually</li>
</ul>
<h4>Co-ordinate Units</h4>
<p>Map Posts uses latitude and longitude co-ordinates in decimal degree (DD) units. This means it will not recognize<br />
co-ordinates in the format of degrees, minutes and seconds (DMS)or with N,S,E or W abbreviations indicating hemisphere.<br />
If you intend to provide co-ordinates manually but they are in a non-supported format, there are a number of online<br />
converters available:</p>
<p><a href="https://geoinfo.sdsu.edu/hightech/LM3/dd1.php" rel="nofollow ugc">Geoinfo San Diego State University</a><br />
<a href="https://www.rapidtables.com/convert/number/degrees-minutes-seconds-to-degrees.html" rel="nofollow ugc">RapidTables</a></p>
<p>or Google:</p>
<p>convert degrees minutes seconds to decimal degrees</p>
<h4>Map Configuration</h4>
<p>You can further customize your map appearance by defining a width, height and initial zoom level.</p>
<ul>
<li>Map Width – as a percentage of width available, from 10 to 100 (default – 75%)</li>
<li>Map Height – in pixels, from 10 to 10 000 (default – 300px)</li>
<li>Initial Map Zoom – from 0 (world) to 18 (highest) – (default – 0)</li>
</ul>
<p>NOTE: Map configuration applies to all maps (Post Map or All Posts Map) inserted in the post. Each post retains its own<br />
configuration.</p>
<h4>Preview Map</h4>
<p>A preview map is used as a visual means to verify post location is correct. It shows the most recently successfully<br />
saved location and the currently configured initial zoom level. The preview map height and width is fixed and<br />
does not reflect custom map configuration. To verify the suitability of a customized height or width, insert a map<br />
in the post and view it in preview mode.</p>
<h3>Preview Map in WordPress 5.x using Block (Gutenberg) Editor</h3>
<p>Map Posts Free was originally built for the classic WordPress editor (WordPress versions 4.x and earlier). It is not yet<br />
up to full block editing standards. As a consequence, the map configuration panel continues to function (values entered<br />
will be saved whenever the post is Saved as Draft, Published or Updated); the preview map however will not update until<br />
the browser is refreshed (or a new edit session started).</p>
<p>To verify map configuration is successfully applied it is therefore recommended to insert a Post Map in the content<br />
and preview the page; or refresh the browser page and verify the preview map updates correctly.</p>
<h4>Saving Configuration</h4>
<p>Location and map configuration is applied whenever a post is updated (when the Save As Draft, Publish or Update button<br />
is clicked, depending on post status). If no data validation errors occur, the values entered will be saved to the<br />
database and map configuration updated. It is possible for changes to be only partially saved – if any configuration<br />
fails, it will revert to its last saved value and a message will be provided to the user.</p>
<h3>Saving Configuration in WordPress 5.0 using Gutenberg Editor</h3>
<p>Saving configuration entered through the metabox works normally however the fields do not update fully until the next<br />
time the editor is loaded. This means that if you update configuration information and click Save as Draft, Update or<br />
Publish, fields will show the last user entered information however you will not see the user message updated to indicate a<br />
successful save or not. If there were input validation issues, error messages will not appear until the next time the post<br />
or page is edited.</p>
<h4>Layer Control</h4>
<p>The public map (but not the preview map used for configuration) includes a layer control that allows map viewers<br />
to select which base map to use (options include Standard, Humanitarian and Black and White OpenStreetMap;<br />
Black and White High Contrast, Natural Terrain and Artistic Map (from Stamen)).</p>
<p>There are also some transparent layers than can be overlain the base maps; these include Trails and Topographic<br />
relief. For the All Posts Map only, all the post locations are collected in a single layer and can be hidden or<br />
made visible from the control as well.</p>
