transformBboxJavaProj

public static com.nutiteq.components.Envelope transformBboxJavaProj(com.nutiteq.components.Envelope bbox,
                                                    String fromProj,
                                                    String toProj)

Reproject bounding box using javaProj library. Slower and not so stable than Proj.4 but does not require NDK

Parameters:

bbox - input bounding box

fromProj - proj4 text

toProj -

Returns:

projected bounding box

transformBboxProj4

public static com.nutiteq.components.Envelope transformBboxProj4(com.nutiteq.components.Envelope bbox,
                                                 String fromProj,
                                                 String toProj)

Reproject bounding box using Proj.4 (NDK) library

Parameters:

bbox - input bounding box

fromProj - proj4 text

toProj -

Returns:

projected bounding box

decompress

public static Vector<com.nutiteq.components.MapPos> decompress(String encoded,
                                               double precision,
                                               com.nutiteq.projections.Projection proj)

decompress Google Polyline Encoding Format. Code ported from http://open.mapquestapi.com/common/encodedecode.html sample

Parameters:

encoded -

precision - , usually 5

proj - result is converted from WGS84 to this projection

Returns:

Vector of MapPos in proj Projection
