Ogre

Ogre is a web client (service) that translates spatial files into GeoJSON using the ogr2ogr command line tool for use in web applications and frameworks.

Convert to GeoJSON

Simplify:

Value for simplifying geometries (useful for curves in DXF files)

Create Mapbox-compatible file (RFC7946)

Enable DXF_ENCODING=UTF-8 config

Enable WRITE_BBOX=YES

Force download

Note: GeoJSON can only support one layer

Get File Information (ogrinfo)

File*:

Upload a spatial file to analyze its information and structure.

Feature Limit:

Limit the number of features returned

Layer Name:

Specific layer to analyze (leave empty for all layers)

Summary only (show schema, projection, extent)

List all layers

Returns detailed information about the spatial file in JSON format

Translate Raster (gdal_translate)

Raster File*:

Upload a raster file (GeoTIFF, etc.) to convert to another format.

Output Format:

Choose the output raster format.

Output Data Type:

Bands (comma-separated):

Specify which bands to include (e.g., "1,2,3" for RGB).

Expand:

Expand single band to multi-band (useful for color tables).

Output Size:

pixels

Scaling (src_min src_max dst_min dst_max):

Source Window (x_off y_off x_size y_size):

Projection Window (ulx uly lrx lry):

Projection Window SRS:

Spatial reference system for the projection window coordinates.

JPEG Quality:

Compression:

NoData Value:

Converts raster files between formats (GeoTIFF, JPEG, PNG).

Get Raster File Information (gdalinfo)
