NAME¶

osgearth_tfs - generate a TFS dataset from a feature source

SYNOPSIS¶

osgearth_tfs
filename [--first-level level | --max-level level | --max-features number | --out path | --layer layer | --description description | --expression expression | --order-by order | --crop | --dest-srs SRS]

DESCRIPTION¶

osgearth_tfs generates a TFS dataset from a feature source such as a shapefile. By pre-processing your features into the gridded structure provided by TFS you can significantly increase performance of large datasets. In addition, the TFS package generated can be served by any standard web server, web enabling your dataset.

OPTIONS¶

filename

Shapefile (or other feature source data file)

--first-level level

The first level where features will be added to the quadtree

--max-level level

The maximum level of the feature quadtree

--max-features number

The maximum number of features per tile

--out path

The destination directory

--layer layer

The name of the layer to be written to the metadata document

--description description

The abstract/description of the layer to be written to the metadata document

--expression expression

The expression to run on the feature source, specific to the feature source

--order-by order

Sort the features, if not already included in the expression. Append DESC for descending order!

--crop

Crops features instead of doing a centroid check. Features can be added to multiple tiles when cropping is enabled.

--dest-srs SRS

The destination SRS string in any format osgEarth can understand (wkt, proj4, epsg). If none is specific the source data SRS will be used.
