Kartogramm

Kartogramm is a vector tiles scheme for serving data from the Estonian Land Board's 1:10K national topographic vector dataset (ETAK). It incorporates some other data sources aswell, listed here. The datasets are transformed to unified schema discussed in more detail here. The main focus is still on high level zooms for Estonia, with additional sources only meant as background information on medium and low levels.

The data model is based on Cartiqo by Webmapper licensed under CC BY-SA 4.0 with some country-specific changes to codelists (wetlands, peat mining areas) and other more general changes as regards to the availability of data. But this here is still a work in progress so further changes might come about.

Layers

Agricultural

Areas used for agricultural purposes. ETAK does not specifically distinguish between types of agricultural land. In order to achieve this would have to do some extra processing based on data from the Agricultural Registers and Information Board. type == greenhouse requires separate attention as it is a collateral area taken from other buildings. This means it will overlap other types of landcover areas.

Labels

Point locations for displaying text labels. Has a hierarchy property which can be used to filter between more important and less important labels, e.g. city names for different zoom levels. And rotation for rotating address labels feet downwards so their base can be shown on a styled map towards the street they're associated with. Address ranges are also available for the national ADS address system house number addresses for which we can establish a related streetline from the topographic database. These are basically a minimum house number on this street and a maximum. Type addressrange is divided into three subtypes: line_start, line_end and line_med stating if the range min/max value is situated in the related streetline start or end of the vector or midway. This makes the label anchoring decisions a bit simpler: e.g. for addressrange.line_start it would make sense to anchor the label at the lower-left corner while for addressrange.line_end in the lower-right corner.

Roads

Roads as linestrings. type encodes the functional class, and in addition class represents the kind of cover for the road. Z-levels in relative_height are recalculated from the original data z-at-the-beginning, z-at-the-end of vector to z-for-linestring. relative_height is encoded as

• -1 - road passes under another road (at z-level 0),
• 0 - road on the same (usually ground) level
• 1 - road passes over another road (at z-level 0)

bridge and tunnel are booleans meant to denote if this section of the road passes over a bridge or goes through a tunnel.

Boolean oneway denotes if this section of the road is meant for oneway car traffic only. True means traffic only in the road vector direction, False that traffic is allowed in both directions.
