Generate an image containing isolines for travel results using an existing
graph. Isolines represent curves of equal cost, with cost typically referring
to the time or distance assigned as the weights of the underlying graph. See
Graphs and Solvers for more
information on graphs.
Additional weights to apply to the edges of an existing graph. Weights must be specified using identifiers; identifiers are grouped as combinations. Identifiers can be used with existing column names, e.g., ‘table.column AS WEIGHTS_EDGE_ID’, or expressions, e.g., ‘ST_LENGTH(wkt) AS WEIGHTS_VALUESPECIFIED’. Any provided weights will be added (in the case of ‘WEIGHTS_VALUESPECIFIED’) to or multiplied with (in the case of ‘WEIGHTS_FACTORSPECIFIED’) the existing weight(s).The default value is an empty array ( [] ).
Additional restrictions to apply to the nodes/edges of an existing graph. Restrictions must be specified using identifiers; identifiers are grouped as combinations. Identifiers can be used with existing column names, e.g., ‘table.column AS RESTRICTIONS_EDGE_ID’, or expressions, e.g., ‘column/2 AS RESTRICTIONS_VALUECOMPARED’. If remove_previous_restrictions is set to true, any provided restrictions will replace the existing restrictions. If remove_previous_restrictions is set to false, any provided restrictions will be added (in the case of ‘RESTRICTIONS_VALUECOMPARED’) to or replaced (in the case of ‘RESTRICTIONS_ONOFFCOMPARED’).The default value is an empty array ( [] ).
Name of the table to output the isochrones to, in [schema_name.]table_name format, using standard name resolution rules and meeting table naming criteria. The table will contain levels and their corresponding WKT geometry. If no value is provided, the table is not generated.The default value is ”.
Color of generated isolines. All color values must be in the format RRGGBB or AARRGGBB (to specify the alpha value). If alpha is specified and flooded contours are enabled, it will be used for as the transparency of the latter.The default value is FF696969.
When input parameter generate_image is set to true, background color of the generated image. All color values must be in the format RRGGBB or AARRGGBB (to specify the alpha value).The default value is 00000000.
When add_labels is set to true, color for the labels. All color values must be in the format RRGGBB or AARRGGBB (to specify the alpha value).The default value is FF000000.
Colormap for contours or fill-in regions when applicable. All color values must be in the format RRGGBB or AARRGGBB (to specify the alpha value).The default value is jet.The supported values are:
Ignore the restrictions applied to the graph during the creation stage and only use the restrictions specified in this request if set to true.The default value is false.The supported values are:
Value-based restriction comparison. Any node or edge with a ‘RESTRICTIONS_VALUECOMPARED’ value greater than the restriction_threshold_value will not be included in the solution.
When specified, assigns the given value to all the edges in the graph. Note that weights provided in input parameter weights_on_edges will override this value.
When input parameter generate_image is set to true, height of the generated image. If the default value is used, the height is set to the value resulting from multiplying the aspect ratio by the width.The default value is -1.
When interpolating the graph solution to generate the isochrone, neighborhood of influence of sample data (in percent of the image/grid).The default value is 20.
When interpolating the graph solution to generate the isochrone, number of subdivisions along the x axis when building the grid (the y is computed using the aspect ratio of the output image).The default value is 100.
When add_labels is set to true, a search window is used to rate the local quality of each isoline. Smooth, continuous, long stretches with relatively flat angles are favored. The provided value is multiplied by the labels_font_size to calculate the final window size.The default value is 4.
When add_labels is set to true, this value determines the distance (in multiples of the labels_font_size) to use when separating labels of different values.The default value is 4.
When add_labels is set to true, this value determines the distance (in percent of the total window size) to use when separating labels of the same value.The default value is 20.
Name of the table to host intermediate solve results, in [schema_name.]table_name format, using standard name resolution rules and meeting table naming criteria. This table will contain the position and cost for each vertex in the graph. If the default value is used, a temporary table is created and deleted once the solution is calculated.The default value is ”.
Factor to qualify the concavity of the isochrone curves. The lower the value, the more convex (with ‘0’ being completely convex and ‘1’ being the most concave).The default value is 0.5. The minimum allowed value is 0. The maximum allowed value is 1.
The Kinetica server embeds the endpoint response inside a standard response structure which contains status information and the actual response to the query. Here is a description of the various fields of the wrapper:
