Description

AgAreaTypePatternCollection used to access the List of coords of the AreaTarget AreaType

Public Methods

Add	Adds a lat lon value. Lat parameter uses Latitude Dimension. Lon parameter uses Longitude Dimension.
Insert	Inserts a lat lon value (the value is inserted into the specified index without having to remove all elements) Lat parameter uses Latitude Dimension. Lon parameter uses Longitude Dimension.
Remove	Remove an Item using a given index.
RemoveAll	Remove all the elements of the collection.
ToArray	Returns the lat lons as a two dimensional array.

Public Properties

Count	Returns the number of lat lons.
Item	Returns the lat lon with the Index.

Example

Define area target boundary and position from list of lat/lon/alt

[C#]

// By using the fine grained interfaces,
// BeginUpdate/EndUpdate prevent intermediate redraws
root.BeginUpdate();
areaTarget.AreaType = AgEAreaType.ePattern;
IAgAreaTypePatternCollection patterns = areaTarget.AreaTypeData as IAgAreaTypePatternCollection;
patterns.Add(40.040, -76.304);
patterns.Add(40.337, -75.922);
patterns.Add(40.028, -75.628);
root.EndUpdate();

List all points in an area target

[C#]

if (areaTarget.AreaType == AgEAreaType.ePattern)
{
    // Get IAgAreaTypePatternCollection interface from AreaTypeData
    IAgAreaTypePatternCollection patternPoints = areaTarget.AreaTypeData as IAgAreaTypePatternCollection;

    // ToArray returns a two dimensional array of latitude and longitude points
    Array areaTargetPoints = patternPoints.ToArray();

    Console.WriteLine("All points in Area Target");
    for (int i = 0; i < areaTargetPoints.GetLength(0); ++i)
    {
        Console.WriteLine("  Latitude {0} Longitude: {1}",
            Convert.ToDouble(areaTargetPoints.GetValue(i, 0)),
            Convert.ToDouble(areaTargetPoints.GetValue(i, 1)));
    }
