Refine search of WMS layers
searches fields of Web map service layers, refined
= refine(layers
,querystr
)layers
, for a partial
match with the string or character vector in querystr
. By
default, refine
searches the Layer
or
LayerName
properties but you can include other fields in the
search using the SearchFields
parameter.
modifies the search based on the values of the named parameters.refined

First find layers in the WMS database that contain temperature information.
temperature = wmsfind('temperature');
Refine the search of temperature layers to find only those layers that contain annual temperature information.
annual = refine(temperature,'annual');
Refine the search of temperature layers to find layers containing only sea surface temperatures.
sst = refine(temperature,'sea surface');
Refine the search of sea surface temperature layers to include only layers that include annual information.
annual_and_sst = refine(sst,'annual');
annual_or_sst = [sst;annual];
layers
— Layers to searchWMSLayer
objectsLayers to search, specified as an array of WMSLayer
objects.
querystr
— Characters to search for in WMSLayer
object fieldsCharacters to search for in WMSLayer
object fields,
specified as a string or character vector. querystr
can
contain the asterisk wildcard character (*).
Example: 'temperature'
Data Types: char
| string
Specify optional
comma-separated pairs of Name,Value
arguments. Name
is
the argument name and Value
is the corresponding value.
Name
must appear inside quotes. You can specify several name and value
pair arguments in any order as
Name1,Value1,...,NameN,ValueN
.

'SearchFields'
— Fields to search in the WMSLayer
objects'layer'
(default) | 'server'
| 'layertitle'
| 'layername'
| 'servertitle'
| 'serverurl'
| 'any'
| 'abstract'
Fields to search in the WMSLayer
objects, specified
as a string, string array, character vector, or cell array of character
vectors. The function searches the values of the specified fields in the
WMSLayer
objects for a partial or exact match
with querystr
. Multiple options may be included in
a string array or cell array of character vectors.
The table lists valid values of
searchFields
.
Field | Behavior |
---|---|
'layer' | Search both the LayerTitle and the
LayerName fields. |
'layername' | Search the LayerName field in the
WMSLayer objects. The layer name
is an abbreviated form of the
LayerTitle field and is the
keyword the server uses to retrieve the layer. |
'layertitle' | Search the LayerTitle field in the
WMSLayer objects. The layer title
includes descriptive information about a layer and
facilitates understanding the meaning of the raster
values of the layer. |
'server' | Search the ServerURL in the
WMSLayer objects. The server URL
and layer information facilitate the reading of raster
layers by the function
wmsread . |
'servertitle' | Search the ServerTitle field in
the WMSLayer objects. A server title
includes descriptive information about the
server. |
'serverurl' | Search the ServerURL in the
WMSLayer objects. The server URL
and layer information facilitate the reading of raster
layers by the function
wmsread . |
'abstract' | Search the abstract field in the
WMSLayer objects. |
'any' | Search all fields. |
Data Types: char

'MatchType'
— Strictness of match'partial'
(default) | 'exact'
Strictness of match, specified as the string or character vector
'partial'
or 'exact'
. If
'MatchType'
is 'exact'
and
querystr
is '*'
, a match
occurs when the search field matches the character
'*'
.
Data Types: char
| string
'IgnoreCase'
— Ignore case when comparing field values to querystr
true
(default) | false
Ignore case when comparing field values to
querystr
, specified as the logical value
true
or false
.
Data Types: logical
