functions:

retrieving fixed tours designing individual tours within the designated areas querying tourist information as texts, pictures, video-clips (e.g. route

profile and description, culture, sight-seeing spots, practical hints) input of individual tour information (required time, prices, comfort etc.) display of calculated elevation profiles compiling a list of mountain huts and stopovers storing the selected information (compiling tour-books) searching for latest information via hyperlinks from the internet printing user-defined selections (e.g. maps, elevation profiles, station-

lists) down-loading a station list to hand-held GPS-receivers

Technical concept:

CD-ROM-version modular architecture (Visual C++) moduls: map-viewer, routing-algorithm, administration of

tours, queries, GPS-interface, printing data base compatible (ODBC), e.g. Oracle, FoxPro,

Access.. special hyperlinks integrated

Data basis

EU-Project AIDA - DataEU-Project AIDA - Data

data required data applied

raster data: general map, backgroundmap - scale 1:50.000

raster data: general map (Fa. HuberKartographie), TK50 of the nationalsurvey authorities from Bavaria andAustria

Problem: Italy

vector data:

routing network (e.g. pathes for hikingand biking, ferries, rack- or cable-railway)

special touristic objects (e.g.possibilities for bed & breakfast, overnightstops and huts, sight-seeing spots)

vector data:

routing network and special touristicobjects – collected and digitized by theconsortium

multimedia data multimedia data: picture, sound, video

Problems in processing the raster data - Topographic map 1:50.000

convinient scale for the visualization of e.g. hiking-paths

high information density originally not produced for a computer visualization

ordering separate layers of raster data leaving out the dispensible symbology for vegetation

supplementary time-intensive workflow (merging layers) huge file-size


Processing the official Bavarian vector data - roads

different format-delivery (OS, DXF) - two different workflows transform the official vector data into one uniform geodetic reference

system (UTM, WGS84) adapting to the AIDA-dictionary digitizing additional objects (field paths, trails, tracks, etc.) changing attributes (e.g. municipal road = path for hiking) very time-

consuming and error-prone

routing along this element would not be possible deleting dispensable geometry (e.g. to much municipal roads) DXF-files double features, because they are delivered with an

overlap to the adjacent files

Different workflow


1) with ATKIS DXF (18 files) - assignment of the objects in different layers to feature-classes DXF to OS OS (19) and DXF-files - adapting to the AIDA-Datamodel Georeferencing all files transport from MGDynamo to MGE and Oracle (OX) Digitizing the additional geometry and special data time-consuming reassignment of the features from ATKIS to AIDA

2) without ATKIS Digitizing the geometry and special data Attribution

Common workflow after digitizing


transport back to MGDynamo (XO) digitizing of tours only in MGDynamo possible (splitting geometry) interactive verification: border-matching, geometric-anomalies

(over-/undershoot), lost attributes, no attributes, bridges, node-connection automatic routine: merging of uniform objects, splitting at cross-points,

assigning system-ID‘s to nodes and edges, ASCII (*.asc) projection the elevation model to geometry - ASCII (*.xyz) Deleting of double-features ASCII-Output for database (*.ln1, *.ln2, *pnt, *xyz)

Official vector data - village boundaries

name of the cell not an attribute stand-alone text-object development of an interactive programme to place and

correct the name (e.g. deleting dashes) verifiying the objects with the analogue map geometry of village boundaries in DXF-format = line

feature OS-format = Polygon problems with the AIDA-dictionary

effort > benefit

digitizing the necessary village boundaries by AGIS


Processing the elevation data

projection of the vector data onto the terrain surface to get 3D-coordinates of all nodes and vertices of the routing network

development of a programme

Processing the semantic and multimedia data

geo-referencing the description of tours, addresses of leisure facilities and services, culture, sight-seeing spots, practical hints as texts, pictures, video-clips
