 Creates a temporary map.  Sets center of map to (-114,51) and scale to 1:50000.  Turns on layers d5d01111 and d5d01118.  The visible layers are rendered as a 500 by 500 PNG image.  No selection is defined or drawn.

+|| [#Version1.0 VERSION] || 1.2.0 || Yes || Operation version ||
+|| [#Session1.0 SESSION] || session identifier || Yes || !MapGuide session identifier containing map to display. ||
+|| [#MapName1.0 MAPNAME] || text || Yes ||Name of the map to display.[[BR]]This corresponds to the !GetName() value for the resource identifier. ||
+|| [#LayerNames1.0 LAYERNAMES] || text || Optional || Comma separated list of layer names. ||
+|| [#MaxFeatures1.0 MAXFEATURES] || integer || Yes || Maximum number of features to select. ||
+|| [#Geometry1.0 GEOMETRY] || text || Yes || WKT string representing the selection geometry. ||
+|| [#SelectionVariant1.0 SELECTIONVARIANT] || text || Yes || Geometric operation to use while selecting. ||
+|| [#Persist1.0 PERSIST] || 0/1 || Yes || If true, selection is saved to map. ||
+|| [#LayerAttributeFilter1.0 LAYERATTRIBUTEFILTER] || integer || Optional || Filter based on layer attributes. ||
+|| [#FeatureFilter1.0 FEATUREFILTER] || text || Optional || Filter based on previous selected features. ||
+==== LAYERNAMES Parameter ==== #LayerNames1.0
+Comma separated list of layer names to restrict the selection to.  Names can be obtained from !MgLayer.!GetName()
+==== MAXFEATURES Parameter ==== #MaxFeatures1.0
+Maximum number of features to select.  If this value is set to "-1", all matching features will be selected.
+==== GEOMETRY Parameter ==== #Geometry1.0
+WKT string representing the selection geometry, eg. "POLYGON((10 10, 10 20, 20 20, 20 15, 10 10))"
+==== SELECTIONVARIANT Parameter ==== #SelectionVariant1.0
+Geometric operation to use for testing features against the supplied geometry.  The following operations are supported:
+ * "TOUCHES" - Feature geometry touches supplied geometry
+ * "INTERSECTS" - Feature geometry intersects supplied geometry
+ * "WITHIN" - Feature geometry lies within supplied goemetry
+ * "ENVELOPEINTERSECTS" - Envelopes of feature and supplied geometry intersect. '''Note:  This was added in !MapGuide 2.1.0'''
+==== PERSIST Parameter ==== #Persist1.0
+If set to "1", the resulting selection from !QueryMapFeatures will be persisted to the map and visible on the next call to !GetDynamicMapOverlayImage or !GetMapImage.
+==== LAYERATTRIBUTEFILTER Parameter ==== #LayerAttributeFilter1.0
+Bitmask specifying the attributes a layer must have to be considered in the selection process.  The following attributes are supported:
+ * 1 - Layer is visible
+ * 2 - Layer is selectable
+ * 4 - Layer has a tooltip defined
+
+Combinations of one or more attributes
+
+==== FEATUREFILTER Parameter ==== #FeatureFilter1.0
+XML filter describing a set of previously selected features.  This paramter is useful for obtaining the attribute values for a set of selected features.  The XML text can be retrieved from !MgSelection.!ToXml().
