The Map Projection

Giraffe is inherently spatial, and every project is geolocated and to scale.

The default projection

Giraffe's default projection is WGS 84, or World Geodetic System 1984.

Most spatial data defaults to this projection.

If you try to import vector layers and they are misaligned, they may be using a different project than the Giraffe default. In that case, you can edit the file to use WGS84 before uploading, or change the projection in Giraffe to match your file.

Use your preferred projection

  1. Find your CRS Code

    Search EPSG.io or SpatialReference.org for your country, specific code, or coordinate system.

    There are a few export options. Giraffe uses PROJ.4 format.

    You will need the PROJ.4 code string to update Giraffe's projection.

    This is a sample PROJ.4 format code for WGS84:

    +proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +wktext +no_defs

    Once found, copy it to your clipboard.

  2. Open Project Settings in Giraffe

    Click the Gear Icon on the left hand palette to open project settings.

    Click the “system” tab

  3. Override the Default CRS Value

    Find the CRS field.

    Click the pencil.

    Delete the existing code from the text box.

    Paste the Proj4 code.

    Click Save.

Refresh your tab to ensure the CRS has taken effect before uploading geo-located data
