Experience from Czech Republic II (Elevation TIN data): Revision
Experience from Czech Republic - September 2017
Description
Process followed to implement an Elevation TIN dataset in Czech Republic according to the INSPIRE Data specification on Elevation, transforming source data from the national DTM.
Implementation of data using TIN spatial representation type is optional in INSPIRE, and is an additional step after the transformation of grid Elevation data set already performed I 2015 by the same organization.
a) CRS transformation to 2D geodetic ETRS89 plus EVRS height, and;
b) Format transformation to GM_Tin (ISO 19197), implemented with gml:TIN structure. Examples of encoding are available, using 2 alternatives: implementing gml:posList and gml:pos.
