MapPackageQuery.BoundsPolygons Property
Gets or sets a flag indicating if the dataset returns bounding polygons for a table in a MapPackageDataSet.
Syntax
public System.Boolean BoundsPolygons { get; set; }Property Value
Default: false
True if bounding polygons are created, False otherwise.
Remarks
If this value is True, a polygon feature is returned for the table a MapPackageDataSet reads, in addition to the data itself. This can be used to study properties of the data that a dataset reads, e.g. the bounds and available resolutions.
A MapPackageDataSet can read different types of data and the attributes set on the bounds polygons vary accordingly. The following attributes are set if the data in table read by a MapPackageDataSet contains rasters:
Attribute | Type | Contains |
|---|---|---|
dataType | Atom | imageRaster or nonImageRaster depending on the type of raster the table contains. |
cellWidth | Double | The width of a cell, in meters, at the highest available resolution. |
cellHeight | Double | The height of a cell, in meters, at the highest available resolution. |
maxCellWidth | Double | The width of a cell, in meters, at the lowest available resolution. |
maxCellHeight | Double | The height of a cell, in meters, at the lowest available resolution. |
If the table read by a MapPackageDataSet contains vectors then the following attributes are set:
Attribute | Type | Contains |
|---|---|---|
dataType | Atom | vector |
featureCount | Integer | The total number of features in the table. |
