Detailed Description

How a layer's vertex Z values are obtained (PLAN §4.1).

source == None means the layer is 2D: its GeoPackage table is created without the 25D flag and FeatureLayer::isThreeD is false. Because that decides the OGR geometry type it is fixed at creation; the SOURCE may be changed afterwards and followed by a Resample Z.

Member Data Documentation

constant

double ZPolicy::constant = 0.0

densifySpacing

double ZPolicy::densifySpacing = 0.0

Insert vertices every densifySpacing map units before sampling, so a breakline drawn with three clicks follows the terrain instead of chording it. <= 0 disables. Must stay >= the mesh minimum cell size or the constraint segments come out sub-cell — the dock warns.

rasterBand

int ZPolicy::rasterBand = 1

resampleOnEdit

bool ZPolicy::resampleOnEdit = true

Re-sample a vertex's Z when it is moved or inserted.

source

Source ZPolicy::source = Source::None

sourceLayerId

QString ZPolicy::sourceLayerId

OpenSWMMVisLayer::layerId() of the raster or mesh.

zScale

double ZPolicy::zScale = 1.0

Vertical unit conversion applied to every sample (raster feet → model metres, etc.). Seeded from GISRasterLayer::detectVerticalUnit.
