String findNearestUTFeature(String version, String featureClassName, String searchExpression, String x, String y, String searchDistance)
Description
Query an UT Object Identifier (OBJ_ID) of the UT object closest to the Point(x,y) from a feature class table, using the searchExpression condition and a spatial filter defined by a buffered Point (x,y).
Parameter |
Value |
|---|---|
version |
Version's fully qualified name (e.g. SDE.DEFAULT). |
featureClassName |
Name of the feature class table. The table name will be qualified by the user name, configured in ags.sde.tableowner. |
x |
X-coordinate of point. |
y |
yYcoordinate of point. |
searchDistance |
A buffer polygon is created around the point with the distance=searchDistance . The spatial search is executed for the buffer polygon with the esriSpatialRelIntersects relationship. This parameter must not be 0 or empty. |
Return value
The returned value is a string with an UT Object Identifier (OBJ_ID). If the query has no result, an empty String is returned.
Example:
1.Search in the FCL_E_PLANT_AREA polygon feature class with an unbuffered point as spatial filter:
<xsl:for-each select="utiapi:findFeaturesByPoint('SDE.DEFAULT','FCL_E_PLANT_AREA','','23425.640','21791.577','')">
<result><xsl:value-of select="." /></result>
</xsl:for-each>
2.Search in the FCL_E_INSTALLATION point feature class with a buffered point as spatial filter:
<xsl:for-each select="utiapi:findFeaturesByPoint('SDE.DEFAULT','FCL_E_INSTALLATION','ACLASS_ID=3001','23425.640','21791.577','10.0')")">
<result><xsl:value-of select="." /></result>
</xsl:for-each>
String findUTFeatureByPoint(String version, String featureClassName, String searchExpression, String x, String y)
Description
Query UT Object Identifier (OBJ_ID) of the UT object with the condition searchexpression and a spatial filter defined by a Point (x,y) from a feature class table. The spatial search is executed for the point with the esriSpatialRelWithin relationship. This function is typically used to find a polygon object that contains the point (x,y).
Parameter |
Value |
|---|---|
version |
Version's fully qualified name (e.g. SDE.DEFAULT) |
featureClassName |
Name of the feature class table. The table name will be qualified by the user name configured in ags.sde.tableow |
searchExpression |
Conditional expression for the query. Can be an empty string. |
x |
x-coordinate of point |
y |
y-coordinate of point |
Return value
The returned value is a string with an UT Object Identifier (OBJ_ID). If multiple objects are found, only the first result is returned. If the query has no results, an empty String is returned.
Example:
1.Search in the FCL_E_PLANT_AREA polygon feature class with an unbuffered point as a spatial filter:
<xsl:for-each select="utiapi:findFeaturesByPoint('SDE.DEFAULT','FCL_E_PLANT_AREA','','23425.640','21791.577','')">
<result><xsl:value-of select="." /></result>
</xsl:for-each>
2.Search in point feature class FCL_E_INSTALLATION with buffered point as spatial filter:
<xsl:for-each select="utiapi:findFeaturesByPoint('SDE.DEFAULT','FCL_E_INSTALLATION','ACLASS_ID=3001','23425.640','21791.577','10.0')")">
<result><xsl:value-of select="." /></result>
</xsl:for-each>
