 ==== Coordinates ====
 The coordinate data will go into field 034 of your MARC record, in subfields $d,$e,$f, and $g.
-You can format your coordinates as decimal degrees (DD) or degrees minutes seconds (DMS), and you can assign hemispheres by using either letters (N,S,E,W) or symbols (+,-).
+You can format your coordinates as decimal degrees (DD) or degrees minutes seconds (DMS), and you can assign hemispheres by using either letters (N,S,E,W) or symbols (+,-). If you omit the + sign, it is considered the default.
 Note that the order for coordinates in the [[http://www.loc.gov/marc/bibliographic/concise/bd034.html|MARC 034 field]], is:
 $d: West; $e: East; $f: North; $g: South
-* Note, [[https://github.com/vufind-org/vufind/pull/1076|PR#1076]] upgrades the code to allow for unsigned DD coordinates. With this patch, positive values do not need to be prefixed with the + sign.
+If malformed coordinates are detected during indexing, an error message containing the record ID, coordinate values, and problems with the coordinate values will be displayed. Malformed coordinates will not be included in the indexed record.

 ===== Displaying Geographic Data =====
+==== Underlying Technology ====
 Starting with VuFind® 5.0, geographic features are displayed with **Leaflet**. For historical information about earlier implementations using OpenLayers and GoogleMaps, click the "Old revisions" button below to find earlier versions of this page.

 Features can be clicked on to show a popup window that will display the label and/or coordinates of that feature depending on how the [MapTab] section is configured in the **geofeatures.ini** file.

-  * The recordMap parameter in geofeatures.ini [MapTab] section has changed from a string to a boolean field in VuFind® 5.0 so that it can be used to toggle the Map Tab display on and off.

 Labels can be read from the long_lat_label field if they are stored in Solr, or assigned on the fly with a look-up table. If you use a look-up table, put it in your local/config/vufind/ directory, and in the geofeatures.ini file, set mapLabels = file:filename.
+:!: // Note:  Starting in VuFind® 7.0., the contentsecuritypolicy.ini file was implemented. You will need to modify this file to include the basemap tileserver domain.

+==== Notes on Map Tiles ====
+Map display depends on access to a tile set to allow zooming and scrolling around the world. The geofeatures.ini file includes some example tile URLs, but tile sets from free providers come with significant limitations on usage. If you wish to use this feature in production, you may need to subscribe to a commercial map provider or else run your own [[configuration:geographic_features:map_tile_server|local tile server]].
+One way to help reduce the amount of map tile server calls is to configure the defaultRecordTab setting in the config.ini file to something other than "Map".

-==== Caveats for VuFind® 3.1 and 4.x ====
-The following functionality was upgraded in VuFind® 5.0. In VuFind® 5.0, all geographic features that intersect the search box are plotted. Center points for rectangle features are clustered and clusters, when hovered over show the range of center points contained within the cluster.
-**Clustering of Rectangle Features** \\
-Search results clustering requires that all clustered features be points. As such, the code calculates the center point for each rectangle feature.
-The code goes through several routines to check for rectangle features that intersect the search box, and to check if the center point of those rectangles land within the search box.
-For those rectangles that intersect the search box and have center points that fall outside of the search box, the code sets the rectangles' center points to the center of the search box.
-**Records with Multiple Geographic Features** \\
-For records that have multiple geographic features, only the first feature that falls within the search box is plotted in the search results.
