func ReadMET

func ReadMET(fp string, print bool) (*Header, *Coll, error)

ReadMET reads a .met blob

func WBcodeToMap

func WBcodeToMap(wbdc uint64) map[uint64]string

WBcodeToMap converts a wbdc into a list of metrics

Types

type Coll

type Coll struct {
	T []time.Time   // [date ID]
	D [][][]float64 // D [date ID][location ID][type ID] or [cell ID][date ID][type ID]
}

Coll holds met data

func (*Coll) Get

func (c *Coll) Get(loc, col int) ([]time.Time, []float64)

Get returns a column of values

func (*Coll) Print

func (c *Coll) Print(wbl []string)

Print prints the data in tabular form

type Header

type Header struct {
	Locations map[int][]interface{}

	WBCD uint64 // waterbalance data code

	ESPG uint32
	// contains filtered or unexported fields
}

Header contains metadata for the .met file

func NewHeader

func NewHeader(dtb, dte time.Time, intvl, nloc, prc int) Header
