Functions ¶
func ExactMap ¶
func ExactMap(records *RecordList, w io.Writer)
exactMap webMap draws a plain map with all records mapped as black disks at their exact coordinates and composes an information box with the taxon name, number of records and date.
func GridMap ¶
func GridMap(records *RecordList, w io.Writer)
voucherMap draws a grid map using lines along a 10 x 10 km UTM grid using datum MGA94. It matches all records to grid cells and draws a black disk for each grid cell that contains at least one record,
func VoucherMap ¶
func VoucherMap(records *RecordList, w io.Writer)
voucherMap draws a grid map and discriminates between cells that contain only anecdotal records (drawn as white disks) and cells that contain at least one vouchered record (drawn as a black disk).
func WebMap ¶
func WebMap(records *RecordList, w io.Writer)
webMap draws a plain map with all records mapped as black disks at their exact coordinates. This type of map is used primarily by the Flora of Tasmania Online site and contains no visually separate information box.
Types ¶
type RecordList ¶
type RecordList struct {
// contains filtered or unexported fields
}
RecordList is a data structure that holds metadata pertaining to all the records of a taxon, such as the name, how many records there are, how many cells are populated (for grid maps), or how many records are anecdotal or vouchered.
func NewRecordList ¶
func NewRecordList(coordData string, name string) (rl *RecordList)
NewRecordList takes in a string of coordinate data and a name for the taxon being mapped. It compares to regular expressions to decide whether the dataset contains voucher information or not, and passes the data to the correct function to compose a RecordList depending on the data type.
func (*RecordList) FileName ¶
func (r *RecordList) FileName() string
FileName returns the name to be used to save the SVG file, composed from the taxon name
func (*RecordList) GetGridRecords ¶
func (or *RecordList) GetGridRecords() (nr *RecordList)
GetGridRecords populates the voucher information for a RecordList, populating cells if there is a record that falls inside them.
func (*RecordList) RecordNumber ¶
func (r *RecordList) RecordNumber() (n int)
RecordNumber returns the total number of records
