The Tile Map Service (TMS) is a widely supported map protocol.
Use it to display a map background from a third party provider or to change the
default map layer.
Before you begin
To add a TMS layer,
you must have a URL to a valid TMS map.
Tip: You can
find many TMS resources on the internet. The article
GeoAnalytics Resources on the
Community site lists many TMS resources, both free and
paid. The lists include the complete URL, copyright text, and if available,
copyright URL to specify in the TMS layer. (The Community site is free to use;
however, you must register an account to gain access to the information.)
Procedure
-
Right-click the map chart visualization, and from the menu, click
Properties.
The
Properties popover is displayed, with the
Map chart popover showing the current layers, in
their layer order, top to bottom.
-
Click
Add new layer at the bottom of the
Map chart list.
A list of the layer options is displayed.
-
From the list, click
TMS layer.
The TMS layer is added to the
Map chart layer list, the
Properties list for the layer is displayed, and
the layer with its default settings is added to the map chart.
Note:
An error icon (

) is displayed in the title bar. (A TMS layer is
not valid until the URL to a valid service is supplied.)
- Required:
Provide the URL to a valid service.
The error icon displayed in the title bar is no longer
displayed.
Note: The URL must be
in the format
http://base/url/{z}/{x}/{y}.
{z} specifies zoom level,
{x} specifies the column number, and
{y} specifies the row number. You do not need
to provide values for the three variables
{z}/{x}/{y} for the map to work.
- Optional:
Optionally, drag and drop the layer to a new
position on the list.
-
Review and set map chart properties to refine the display.
Note that it is mandatory to include copyright information for
the vast majority of third-party map providers. Open the
Copyright section of the
Properties popover to configure the copyright
info.
Tip: You
can reuse the settings of an already existing layer. Select
Duplicate layer in the
Properties popover to duplicate either the
selected layer in the same map chart, or to add a copy of a layer from another
map chart in the analysis. See
Duplicating a layer for detailed instructions.
TMS layer
example
In this example, the map chart has a feature layer displaying the
outlines of Australia counties on top of a TMS layer.
- The feature layer for
Australia Counties is available in the
geocoding data tables provided in the
library. The transparency is set to a high degree to show outline and shading.
The feature layer is the top layer of the map chart.
- The standard map layer is
removed. The TMS layer replaces the standard map.
- The TMS layer is drawn
from a map from OpenStreetMap, so the
Title property is set to
OpenStreetMap.
- The
URL is set to
http://a.tile.openstreetmap.org/{z}/{x}/{y}.png.
