Flip lon/lat in geojson documents


The following command converts a CSV (via VRT file) to SHP (and converts the coordinates):
Best sure to change the output: "data\square\webeocCopy.shp"
and the source (VRT): "data\square\webeocCopy.vrt"

ogr2ogr -f "ESRI Shapefile" "data\square\webeocCopy.shp" "data\square\webeocCopy.vrt" -s_srs "+proj=latlong +datum=WGS84 +axis=neu +wktext" -t_srs "+proj=latlong +datum=WGS84 +axis=enu +wktext"

VRT File (open in notepad an save out as VRT):

<OGRVRTLayer name="webeocCopy">
<GeometryField encoding="WKT" field='LINE'/>

Hexagonal Grids
Hexagonal grids are used in some games but aren’t quite as straightforward or common as square grids. I’ve been collecting hex grid resources for nearly 20 years, and wrote this guide to the most elegant approaches that lead to the simplest code, largely based on the guides by Charles Fu and Clark Verbrugge. I’ll describe the various ways to make hex grids, the relationships between them, as well as some common algorithms. Many parts of this page are interactive; choosing a type of grid will update diagrams, code, and text to match.
