According to our information the following outcomes, in the form of Public Deliverables,  will be produced during the lifetime of the project.  If our information is incorrect, please contact the TWEURO team so that we can correct our list and provide links to the published material.  We are happy to host public material for projects.

In Karlsruhe there are two main participants for validation of the highspeed communication network. They are VLA Karlsruhe (department of surveying and real estate administration) as municipal user and Kreutler GmbH (producing software for fire and police services) as commercial user.

The existing geographical data is composed by colour aerial photographs in the scale of 1:5000, grey scale aerial photographs in 1:3000, maps in 1:2000 and SICAD data. Current data formats are TIFF for raster data and SICAD-SQD for vector data.

Both VLA Karlsruhe and Kreutler GmbH need a geographical information system. Both want a seamless data base produced by mosaicking of digital orthophotos. Vector and raster data shall be blended and three-dimensional interpretation of particular territories shall be possible. In this data base it shall be possible to watch the geographical information at any scale - if suitable data exists. The increasing and decreasing shall be managed by windows technics or by manual input of scale.

There are also different requirements. For example VLA is interested in recording the development of the city and Kreutler GmbH needs data of current traffic conditions. The user requirements of administrative and private users are rather similar. They do not contradict but only complete one another.

Many explorations were made in order to find out which hard- and software components are lacking to realize user requirements described in D01. Further the conceptions and plannings for an Image Access System (IAS) and a Fire Service System (FSS-OS/Fire) have been setup. The High-Speed Communication Network (HCN) serves as the backbone of the whole system to be installed and validated at VLA Karlsruhe. A gateway with super-firewall properties to external users is another important feature of the whole Telematic Application System.

First explorations concerning needed resolution of scanned aerial photographs were made. For that purpose the same image was displayed and printed with different resolutions. To save mass storage rectified images shall be saved in a compressed form. For this reason several data compression programs were tested. After these both explorations rectification was carried out with two different programs in order to find weak points or lacking software components. On this occasion a digital administration of surveying data was missed. The experimental image processing program DIDIX of IPF shall be adjusted to given applications. For transformation and resampling DIDIX is suitable to solve the given problems accurately and quickly but the usage of DEM was not planed. This function has to be integrated in any case. Additionally there are two minor functions lacking. First any arbitrary rotation of image shall be processed equally. Second it shall be possible to weight identical points related to their accuracy.

Unfortunately there are some parts of production which can be badly automated. The cut out of needed parts of images is one of them, because the lines of intersection have to be chosen carefully. The new created seamless database will be cut into little pieces which can be administrated, decompressed and displayed quickly and easily. After cutting them they will be compressed.

There are software components lacking for production of database but there is also needed an efficient administration of tiles. In the beginning this will be a coordinate based administration. A practical service would be to keep ready images of some often used scales. It would be easier for the user to manage large scale images if there was a general view in little scale. For other applications an enlarged version of tile would be useful.
