Topographic BaseMap


Plan

Introduction

Specification documents

The envisaged production process


Introduction


Main principles

BaseMap is a pyramid of digital maps displaying ELF base data, at different levels of zoom

WMTS service

Content : themes AU, BU, LC, HY, TN and GN (EL to be added later)

Geographic extend : geographic Europe (oversea territories excluded)

Main use cases

Consultation Background map for applications

CRS: pseudo Mercator (EPSG:3857) and LAEA (EPSG:3035)

Levels of zoom : from a standardized list

From 2k to 40M


Methodology

Zoom levels 2k to

72k : (mainly)

national data

Zoom levels 144k to

40 M : EG products

BaseMap data model

Provides

BaseMap simple data model itself

Matching guidelines between ELF data model and BaseMap

Makes NMCAs aware of the expected content of BaseMap

Feature types

Attributes to be used for

– Selection criteria (generalisation)

– Different symbols


SLD (Style Layer Descripton)

Standardised way to document portrayal rules

Provides

Layer name

Layer source : feature type + OGC filter if relevant

Scale range

Symbol to be applied


Other documents Scale Master

Excel spreadsheet

Provides overview of content and generalisation rules

Map file : implementation of SLD for WMS Server (GeoServer)

The webinar

NOTE : BaseMap model and SLD are the reference documents


Methodology : Scale Master

Provides an overview of the BaseMap content for all zoom levels

Generalisation

Methodology : Scale Master

Another sheet “Key” provides

the details about the

generalisation rules to be

applied

Envisaged production process

Transformation process WFS WMS

rules (SLD)

Technical issues:

some WMS servers do not accept GML as

input data (but only data from database)

INSPIRE models too complex (e.g. TN)

Organisational issues:

ELF data not yet available everywhere

Production process

Design phase :

The BaseMap team (mainly kartverket - Norway) is designing:

– Common portrayal rules

– Using a common ELF/INSPIRE based terminology to name the features and attributes

– Documented in a SLD (Style Layer Description) file

Experimentation on Pilot BaseMap in Nordic cluster (Norway, Finland, Sweden, Netherlands)

Production phase

set up WMS national services using the common portrayal rules

– Master data : NMCAs

– Regional/global data : kartverket

Set up WMTS : kartverket (harvesting national WMS) } Additional support

from some NMCA in reviewing SLDs (v3.1)


Production process summary

Each NMCA may choose:

• Production option (it may depend on themes)

• Source data: Master level 1 or Master Level 2 or both (recommended option)

Drawbacks

No systematic use of ELF data (initial objective)

Heterogeneous production process

Advantages

Pragmatic approach, ensures feasibility of BaseMap during ELF time

NMCAs may contribute to BaseMap without having transformed their data to INSPIRE / ELF model (option 3)

NMCA late in transformation process

NMCA new partner (consortium member or just data and service provider)

NMCA not responsible for INSPIRE theme

WMS TECHNICAL REQUIREMENTS

CRS EPSG:3035 EPSG:3857

Formats

Output formats should include at

least one format that supports

transparency.

Extent

We must have an extent at the

service level to be used in the

cascading service.


WMS TECHNICAL REQUIREMENTS

Data

Extent

Only data within the land

boundary of the country.

Authentication

Service must be open or

available through

standard authentication.

Performance

Fast enough for caching,

handle preseeding traffic

Resolution

The resolution must be

set to 96 DPI.


SERVICE QUALITY

Testing has to be done internally

Regional testing by regional coordinators

Portrayal

Edge-matching

Central test

During integration with WMTS service

Pre-Seeding

From Zoom Level 0 – 15 (this

includes 2 national service levels)

After that only preseed bbox’s for

high use/importance areas.

Update

Frequency Once a year


SEEDING

‘Preseeding from zoom level

0 – 15 inclusive’

Preseeding the first 2

zoom levels where

master (national) data

used 30 HOURS

0-15/10 machines/4cores

7500 HOURS

0-18/10 machines/4cores

‘’Only preseed bbox’s for

high use/importance areas

A set of bounding boxes

for each country covering

no more than x sq km in

total


SEEDING

SEEDING AGREEMENT • When the seeding takes

place

• How many threads

• High use/importance

BBOX’s

UPDATE FREQUENCY

• One time job for project

• Once a year after the

lifetime of the project.

Conclusions Shading will be added (EL theme from EuroDEM data)

The result is an image (WMTS) => the method is not important

Choice of source data (LoD) Choice of production process

The SLD is provided as recommendation but is adaptable

Choice of option 3 (use of existing data) Multiple names (multilingualism) Legend simplification (if “portrayal” attribute is missing)

Objective is base map with simple content.

Expected results before ………….. 2016 (for new countries)

up to NMCAs ; may differ according to the

theme

Choose the method(s) that

are easiest and quickest for

you
