testing
This package contains functions and variables for using pre made geometries.
The tile variables are very large and are initially stored as strings. In order
to access them, you must first compile compile them by calling CompileTiles.
Once compiled, access the tiles via the Tiles function (this does no processing
besides endusring that compilation has already occured).

Functions ¶
func BoxPolygon ¶
BoxPolygon returns a polygon that is a box with side lengths of dim, a clockwise winding order, and points at (0, 0) and (dim, dim).
func CompileTiles ¶
CompileTiles will compile some Natural Earth tiles so they are accessible through the Tiles function. It takes a WKT decoding function which can be accessible in the package github.com/go-spatial/geom/encoding/wkt as the function DecodeString.
package my_test
import (
gtesting "github.com/go-spatial/testing"
"github.com/go-spatial/geom/encoding/wkt"
)
func init {
// put this in init so benchmarks aren't skewed
gtesting.CompileTiles(wkt.DecodeString)
}
func TestMy(t *testing) {
tiles := gtesting.Tiles()
...
}
func FuncLineString ¶
func FuncLineString(start, end float64, points int, fn ParamFunc) geom.LineString
FuncLineString returns a line string constructed from calling fn in the interval [start, end] points number of times. The number of points must be >= 2, or the function panics.
func SelfIntBoxLineString ¶
func SelfIntBoxLineString(dim float64) geom.LineString
func SinLineString ¶
func SinLineString(amp, start, end float64, points int) geom.LineString
SinLineString returns a line string that is a sin wave with the given amplitude and domain (x values) of the set [start, end]. points is the number of points in the line and must be >= 2, or the function panics.
func Tiles ¶
func Tiles() []geom.Collection
Tiles returns geom.Collections that represent Natural Earth tiles generated with the utility https://github.com/ear7h/tile-dump. The tiles must be compiled at runtime by calling the CompileTiles function (see documentation for it) or this funciton will panic.
package my_test
import (
gtesting "github.com/go-spatial/testing"
"github.com/go-spatial/geom/encoding/wkt"
)
func init {
// put this in init so benchmarks aren't skewed
gtesting.CompileTiles(wkt.DecodeString)
}
func TestMy(t *testing) {
tiles := gtesting.Tiles()
...
}
