Use limitation

Do not use for navigation

Use limitation

The product is not designed for use at scales of more than 1:15 000.

Use limitation

The High Resolution Coastline file can be freely used in the integrated databases or services, under the following conditions:

- explicit mention of the source by indicating "©IGN-Shom 2009" when displayed,

- clear indication to the user of any restrictions which apply to data,

- website references must show the Shom and IGNF logo and a link to their website www.shom.fr www.ign.fr.

Use limitation

The Histolitt® coastline was not designed for use in the operation of nuclear facilities, air navigation or communications systems, navigation or air traffic control systems, or any other area referred to as "hazardous activities", where a failure of the product could result in death, personal injury or serious physical or environmental damage. In general, the precision is decametric in planimetry. In some particular areas (especially flat areas), the accuracy can be of the order of several tens of meters. Precision specifications, from which the limits of use must be deduced according to the rules of the art specific to each use, can be found in the document "Technical specifications of the Histolitt shoreline product".

Use limitation

The product is distributed under an Opendata license (version 2.0, April 2017), defined by the Etalab mission.

Statement

The Histolitt® coastline solution comprises information from:

- information obtained from TC25000. TC25000 was digitalised by an operator from Nautical Charts with a scale greater than 1/25000. 1:5,000 charts were used in some port areas. Only 1:50,000 charts are available for the Landes coastal area. The nautical charts used are taken from the Shom range for 1992. The Shom Nautical chart coast line uses:

i. Shom photograms

ii. topographical fair sheets

iii. IGN 1:25 000 maps

- BDTOPO?Country version 1.2 solution class information [line section] where the "TYPE" attribute is set to "High water". - 2D data entered on a BDORTHO? image layer. The process involves updating TC25000 using TCBDTOPO

and the BDORTHO? solution. The Histolitt® coast line is the final result. The most recent versions of the TOPO database coast line and the ORTHO? database when the production process was applied were used.

The topology was constructed during this process: the Histolitt® coast line is continuous, but broken down into several polylines at key points on the coast line. Islands shown as a surface object are closed polylines. Identical attribute sections are merged.

This production process was applied from 15 September 2006 to 14 April 2007.
