3.1.1. AnalyzeData¶

class pyprom.feature_discovery.AnalyzeData(datamap)[source]¶

Analyze Data is responsible for discovering the following features: pyprom.lib.locations.saddle.Saddle, pyprom.lib.locations.summit.Summit, pyprom.lib.locations.runoff.Runoff

__init__(datamap)[source]¶

Parameters:	datamap – datamap to discover features on.
Type:	`pyprom.lib.datamap.DataMap` object.

__weakref__¶: list of weak references to the object (if defined)

analyze()[source]¶

Analyze Routine. Looks for pyprom.lib.locations.summit.Summit, pyprom.lib.locations.saddle.Saddle and pyprom.lib.locations.runoff.Runoff features

Returns:	Containers
Return type:	`pyprom.lib.containers.saddles.SaddlesContainer`, `pyprom.lib.containers.summits.SummitsContainer`, `pyprom.lib.containers.runoffs.RunoffsContainer`,

analyze_multipoint(x, y, ptElevation)[source]¶

Logic for analyzing a feature which fits the definition of a multipoint.

Parameters:	x (int) – x coordinate in raster data. y (int) – y coordinate in raster data. ptElevation (int, float) – Elevation of Multipoint Blob
Returns:	Discovered feature or None
Return type:	`pyprom.lib.locations.saddle.Saddle`, `pyprom.lib.locations.summit.Summit`, or None.

consolidatedFeatureLogic(x, y, perimeter, multipoint, edge, edgePoints)[source]¶

Consolidated Feature Logic analyzes the highEdges around a point or multipoint and determines if the pattern matches a pyprom.lib.locations.saddle.Saddle, pyprom.lib.locations.summit.Summit or pyprom.lib.locations.runoff.Runoff

Parameters:	x (int) – x coordinate in raster data. y (int) – y coordinate in raster data. perimeter (`pyprom.lib.containers.perimeter.Perimeter`) – Perimeter container multipoint (`pyprom.lib.containers.multipoint.MultiPoint`) – MultiPoint container edge (bool) – is this feature on the map edge?
Returns:	List of Container Objects.
Return type:	`pyprom.lib.containers.spot_elevation.SpotElevationContainer` child objects.

run()[source]¶

Shortcut for running analysis. This will find all features on the datamap, as well as rebuild all pyprom.lib.locations.saddle.Saddle into a more digestible format with accurate midpoints and only 2 high edges a piece.

Returns:	Containers with features
Return type:	`pyprom.lib.containers.saddles.SaddlesContainer` `pyprom.lib.containers.summits.SummitsContainer` `pyprom.lib.containers.runoffs.RunoffsContainer`

summit_and_saddle(x, y)[source]¶

summit_and_saddle does that actual discovery of pyprom.lib.locations.saddle.Saddle, or pyprom.lib.locations.summit.Summit

Parameters:	x (int) – x coordinate in raster data. y (int) – y coordinate in raster data.
Returns:	Disocvered Feature, or None
Return type:	`pyprom.lib.locations.saddle.Saddle` `pyprom.lib.locations.summit.Summit` or `pyprom.lib.locations.runoff.Runoff`, or None.
