LisyTrans is a program for the exchange of sewer network data with the programs KAREL or HYKAS worked on or to be worked on. For the data exchange, the program LisyTrans is equipped with the interface INTERLIS VSA-DSS (Switzerland), ISYBAU XML 2006 and Shape. Data can be both imported and exported.
Supported interfaces
LisyTrans represents the basic program for the conversion of Rehm data into different standardized formats. These formats must be merged over associated interfaces in LisyTrans (e. g. INTERLIS (VSA-DSS HYKAS, KAREL) for the conversion into the INTERLIS-Format).
At the moment, following interfaces are supported:
Interface description INTERLIS VSA DSS (HYKAS, KAREL)
In order to export the data from Rehm-Project (HYKAS and/or KAREL) into INTERLIS-file, or vice versa from INTERLIS to Rehm to import, you must indicate the path for the Rehm project database (*.rdb), the pertinent reference database (*.mdb), as well as the target file (e.g. INTERLIS-file). if the target files are not yet present, then new file is created. During the data transfer, a log file is put, from which you can infer the possible arisen transfer errors.
The INTERLIS-interface supports the data exchange of the Rehm Lisy-database (MS Access-Database) to & from INTERLIS with the INTERLIS-Modell VSA-DSS. With the data export, a Interlis 1-Data is produced after VSA-DSS Modell DSS_02i_1_00. Here only the data are exchanged, which are contained necessarily for the hydraulic computation with the program HYKAS and/or Sewer Information System KAREL.
In the year 1991, for the first time, "Interlis - appeared- a data exchange mechanism for land information systems". Main aim and purpose of INTERLIS is to adjust the most accurate description of the data. This mechanism consists of a conceptual specification language and a sequential transfer format with special consideration of space referenced data (short geo data). Thus the compatibility under the systems and a long-term availability becomes possible, i.e. archieving and documentation of the data become possible.
INTERLIS - Model VSA-DSS
The VSA-DSS Modell was developed by the "Verband Schweizer Abwasser- und Gewässerschutzfachleute". With this guideline "Datenstruktur Siedlungsentwässerung" are the structure of an integrated volume of data settlement drainage due to a comprehensive and specialized example to be made possible.
Die VSA-DSS is defined as an object model. Objects are concepts, abstractions or articles with clear demarcations and a precise meaning for the lining up of problem. Examples for the waste water area: catchment areas or manholes. Objects (classes) are characterized through attributes. As an example of the standard object (class) - manhole has the following attributes: Designation, layer, geometry, year of construction, etc.
ISYBAU XML 2006
The ISYBAU-exchange format for wastewater offers the standardized data exchange between client (e.g. national building management) and contractor (e.g. engineer's office) or other project-taken part (e.g. engineer's office for measurement or inspection company).
With the ISYBAU exchange format in the XML format for collection and for the change of waste water-technical data also the view to uniform inventory documentation is considered to the increased technical and legal requirements. By the introduction of the European standard DIN EN 13508-2 "condition of drainage systems outside of buildings - part of 2: Coding system for the optical inspection " made it necessarily to develop an alternative for the past ISYBAU interface 1996-2001. The updating was made in such a way that the old ISYBAU exchange is contained in the new version completely.
The contents of the new interface ISYBAU XML 2006 are in XML (EXtensible Markup Language)-Format Version 1.0 described. The XML format in the version 1.0 was standardized by the W3C (World Wide Web Consortium).
XML makes possible for the separation from structure and data. With respect to the new XML ISYBAU exchange format, in principle between five data areas, one differentiates:
| • | Meta data |
| • | Master data |
| • | Status data |
| • | Hydraulic Data (not yet implemented) |
| • | Operational data (not yet implemented) |
The individual data areas can be imported both into our Rehm data base Lisy and/or exported from the data base.
Shape
The file format Shape is from ESRI (Environmental system Research of institutes, Inc.) for ArcView was originally developed format for geo data. It spread to a standard format in the GIS field. Shape files are vector data, which can contain also additional attributes beside geographical data. Shapefiles can describe points, linear elements and two dimensional elements. The Shape format consists of at least 3 files: a main file (.shp), an index file (.shx) and Dbase a data base for the attributes (.dbf).
Shape files, which are produced with LisyTrans, can be opened and regarded as the simplest type which can be opened with the free Arc Explorer of ESRI.
In this way planning offices, projects with GraPS or HYKAS worked on and/or computed are, over the Shape interface in the program LisyTrans, in the Shape format convert and pass on in this form to the client. Without GraPS and AutoCAD, only with the Arc Explorer, the client can plot the project in simple form and transfer the attributes (e.g. pipeline and manhole designations, nominal size, pipe material etc.) . Attributes can be indicated for pipelines, manholes and catchment areas.
The Arc Explorer has also an query generator, with which SQL queries can be produced in order to evaluate the data (attributes) further.
