Member Function Documentation

◆ CreateGISBasedOnType()

tmGISData * tmGISData::CreateGISBasedOnType ( const int & gis_format_index )

static

Create an object of the specified format.

Allowed values for gis_format_index are those from the tmGISDATA_RASTER_TYPES and from the tmGISDATA_VECTOR_TYPES

Parameters

gis_format_index zero based index of the item type to create

Returns: pointer to an object of the correct type or nullptr if something's going wrong

◆ GetAllData()

virtual wxArrayLong * tmGISData::GetAllData ( )

inlinevirtual

Reimplemented in tmGISDataVectorMYSQL, and tmGISDataVectorSHP.

◆ GetAllSupportedGISFormatsExtensions()

wxArrayString tmGISData::GetAllSupportedGISFormatsExtensions ( )

static

Returning all extensions in an array string.

All supported extensions in an array string but not the mysql one (because no extension is valid for that format).

Note: Raster format are returned first

Returns: all supported extension, raster ones first

Author: Lucien Schreiber (c) CREALP 2008

Date: 06 August 2008

◆ GetAllSupportedGISFormatsWildcards()

wxString tmGISData::GetAllSupportedGISFormatsWildcards ( )

static

Return all supported formats.

Return the wildcards of all supported formats for loading.

Returns: A String containing all supported formats as wildcards that one may use in a dialog box for file selection

Author: Lucien Schreiber (c) CREALP 2008

◆ GetMetaDataAsHtml()

virtual wxString tmGISData::GetMetaDataAsHtml ( )

inlinevirtual

Reimplemented in tmGISDataRaster, tmGISDataVectorMYSQL, and tmGISDataVectorSHP.

◆ GetMinimalBoundingRectangleAsHtml()

wxString tmGISData::GetMinimalBoundingRectangleAsHtml ( int iprecision = 2 )

protected

Get Minimal bounding rectangle as html.

This function is intented for getting minimal bounding rectangle for metadata

Returns: An html compliant string

◆ InitGISDrivers()

void tmGISData::InitGISDrivers	(	bool	bRaster = `TRUE`,
		bool	bVector = `TRUE`
	)

static

Init the GDAL / OGR driver.

Call this function during program startup to allow all GDAL / OGR drivers to be loaded.

Parameters

bRaster	Should we load all GDAL rasters drivers
bVector	Should we load all OGR vector drivers

Date: 14 July 2008

◆ LoadLayer()

tmGISData * tmGISData::LoadLayer ( tmLayerProperties * layerProp )

static

Call this function for loading a layer.

This function create an object of type tmGISData based on layer properties

Parameters

layerProp the layer properties

Returns: a valid tmGISData object or nullptr if an error occur

◆ Open()

bool tmGISData::Open	(	const wxString &	filename,
		bool	bReadWrite = `TRUE`
	)

virtual

Generic open code.

Mainly init member values used by all GIS class

Parameters

filename	path and name of the GIS data to open
bReadWrite	Should we open the dataset for r/w operations ?

Returns: Allways TRUE
