getGISBufferInfo
Version
1.4
Parameters
| Parameter | Type | Description |
|---|---|---|
| svc | string | GIS service name. |
| layer | string | GIS layer on which the function creates buffer zones around the input GIS object. |
| numDistance | integer | The distance (in feet) around the to-be-buffered GIS object in which buffer zones are created on the specified layer. A positive distance means creating buffers outside the GIS object while a negative distance means creating buffers inside the GIS object. When the buffer distance is negative, GIS checks whether the to-be-buffered GIS object is a point, line, or polygon. If it is a point or line, GIS changes the negative buffer distance to 0.01 to avoid the script error. |
| attribute1…attributen (optional) | strings | Additional attributes of the GIS layer to retrieve. |
Returns
Returns an array of associative arrays. Each element in the outer array is a GIS object (from the indicated layer) within the buffer from the record's GIS object. Each element in the inner associative array is a requested attribute.
Example
x = getGISBufferInfo("NewtonCounty","Parcels","50","NAME1","TOTACRES");
x[0]["TOTACRES"] = 0.46
x[0]["NAME1"] = "JENNINGS DEMETRIA C"
x[1]["TOTACRES"] = 0.46
x[1]["NAME1"] = "SIMMS ROCK & VALARIE"
x[2]["TOTACRES"] = 0.46
x[3]["NAME1"] = "PAUL NEVILLE & MARGARET"
