Already since 1991 KilletSoft provides geodata of the Federal Republic of Germany with georeferenced towns, municipalities, urban districts and other administrative units, postal codes and dialling codes. Each data record is georeferenced using Lon/Lat, UTM and Gauss-Krueger coordinates with ETRS89 and DHDN datum, so the data can easily be displayed on a map or imported into any GIS using provided KML, GPX and Shape files standard geographic formats. Starting in 2005, the database were supplemented by natural areas, landscapes, climatic and touristic information, which can be linked by index to the database tables mentioned above. The data are provided with a consistent structure in established CSV and GIS formats that are easy to import into any software and database management system. Geodata Germany are provided in highest accuracy and topicality and they are subject to continuous quality control.
The locality database contains geodata of Germany with tables of georeferenced towns, municipalities, urban districts and other administrative units, postal codes, dialling codes and nature areas, landscapes and climatic information and also registers of the official topographical cartographies. The database tables contain coordinates and elevation data for navigation and geocoding, perimeter searches and distance calculations, and are suitable for the spatial allocation of ecological and economical information. The information is stored in several database tables that can be linked together by the official municipality key.
Quite often it is necessary to reference an address field e.g. like town or municipality name, postal code or dialling code, to corresponding geographical data and coordinates - a georeference. The georeference can be used for example to direct a customer to the closest store locations of a retail store chain by doing a proximity search. Or on the basis of the determined georeferences statistics or general maps can be made. Another possibility it to determine distances between the different objects of the database tables with the georeferences contained therein. The georeferences are available as UTM coordinates, Gauss-Krueger-Coordinates, Geographical Coordinates and as Plus Codes in degree and deg/min/sec notation. With the elevation data from a Digital Elevation Model the ground level height of each place can be determined. Often the knowledge is necessary about affiliations and relationships between data derived from different hierarchies. So it can be determined to which Federal State, governmental area or governmental county a town, a postal code or a dialling code is assigned. Or it can be determined on which topographic map a town or urban district is mapped or in which Federal State a certain town is to find.
It is possible to assign a variety of natural, scenic, climatic and touristic information to each town or municipality. Snow and wind load zones and solar irradiations are available as local climatic data. In conjunction with the ground level heights the snow and wind load zones can be used to calculate static loads for the planning of building constructions. The solar irradiation data can be used to schedule thermal and photovoltaic solar power systems.
The data base also contains registers of the official topographical cartographies TK25, TK50, TK100 and TKÜ200 of the Federal Republic of Germany. Map names and map numbers, corner coordinates and supplemental data of the official topographical maps are included in the registers.
Geographical coordinates in degree notation are particularly well suitable for map views and researches with Google Earth, Google Maps and OpenStreetMap. As an example here an Internet URL is presented using the free Google API with the coordinate of KilletSoft's hometown Kempen for displaying a map on Google Maps. The first value behind the identifier ";query" is the geographical latitude, then the geographical longitude follows. The shown source below can be inserted directly into an anchor tag to present the map.

The geodata offered here are in high-precision quality and are present in different Coordinate and Reference Systems. They are constantly updated and they are subject of a constant quality control. Nevertheless, it is possible that with such large amounts of data deviations of the data contents from reality can occur to a small extent. We have to emphasize expressly that deviations or errors of less than one percent of the data volume of a database cannot be faulted. Should you even notice such deviations, we will endeavor to correct them promptly.
The coordinates are present as geographic coordinates, as Gauss-Krueger coordinates of the 3rd meridian strip and as UTM coordinates on the 32th meridian strip. Because UTM coordinates and Gauss-Krueger coordinates are converted to a uniform meridian strip, distances between two points can be calculated by the simple execution of the Pythagoras theorem. That has the advantage in relation to the computation with geographical coordinates (see below) that it is substantially simpler and much faster. The result is the distance between the points in meters.
Formula for the distance calculation with Gauss-Krueger coordinates: difEast = abs(GKRECHTS1 - GKRECHTS2) difNorth = abs(GKHOCH1 - GKHOCH2) l = sqrt(difEast * difEast + difNorth * difNorth) with GKRECHTS1: Easting of the first coordinate GKHOCH1: Northing of the first coordinate GKRECHTS2: Easting of the second coordinate GKHOCH2: Northing of the second coordinate abs(): Absolute value function sqrt(): Square root function l: Distance in meters as result. Formula for the distance calculation with UTM coordinates: difEast = abs(UTMRECHTS1 - UTMRECHTS2) difNorth = abs(UTMHOCH1 - UTMHOCH2) l = sqrt(difEast * difEast + difNorth * difNorth) with UTMRECHTS1: Easting of the first coordinate UTMHOCH1: Northing of the first coordinate UTMRECHTS2: Easting of the second coordinate UTMHOCH2: Northing of the second coordinate abs(): Absolute value function sqrt(): Square root function l: Distance in meters as result.
Geographic coordinates are indicated in longitude and latitude. Usually longitude and latitude are represented in the degree notation, which is also called decimal notation. Geographical coordinates in the degree notation are for the distance computation better suitable than geographical coordinates in the degrees/minutes/second notation. For a distance computation the longitude and latitude of the first point (LAENGE_D1, BREITE_D1) and the longitude and latitude of the second point (LAENGE_D2, BREITE_D2) are needed. If the latitude has a minus sign, the point is on the southern earth hemisphere, otherwise on the northern earth hemisphere. If a longitude has a minus sign, the point is situated west of the Greenwich meridian, otherwise east of it. In the Federal Republic of Germany no minus signs occur, because all coordinates are on the northern earth hemisphere and east of Greenwich.
As preparation for the distance computation the longitude and latitude are converted into radians. The unit of the radian is [rad]. Lon1r = LAENGE_D1 * PI / 180 Lat1r = BREITE_D1 * PI / 180 Lon1r = LAENGE_D2 * PI / 180 Lat1r = BREITE_D2 * PI / 180 with LAENGE_D1: Longitude of the first point in degree notation BREITE_D1: Latitude of the first point in degree notation LAENGE_D2: Longitude of the second point in degree notation BREITE_D2: Latitude of the second point in degree notation Lon1r: Radian of the longitude of the first point Lat1r: Radian of the latitude of the first point Lon1r: Radian of the longitude of the second point Lat1r: Radian of the latitude of the second point PI: Circle constant Pi Now the longitudes and latitudes of the two coordinates are so far prepared that they can be inserted into the formula for the distance computation. l = r * acos[sin(Lat1r) * sin(Lat2r) + cos(Lat1r) * cos(Lat2r) * cos(Lon2r - Lon1r)] with sin(): Sinus function cos(): Cosinus function acos(): Arcus Cosinus function r: Earth equatorial radius = 6378137 meter l: Distance in meters as result
The conversion of the geographic, Gauss-Krueger and UTM coordinates into another coordinate and/or Reference System, can be accomplished with the Coordinate Transformation program TRANSDATpro or as purchase order. Like that it is possible to convert e.g. into the Lambert Coordinate System or to Soldner coordinates and into the usual Reference Systems.
Wir haben für jeden Datensatz in den Orts-Datenbanken ORTGEM / ORTREF und in den Ortsteil-Datenbanken ORTTLGEM / ORTTLREF eindeutige Datensatz-IDs generiert. Das hat den Vorteil, dass aktualisierte Daten bei einem Update ohne großen Aufwand in den eigenen Datenbestand eingepflegt werden können. Eine Datensatz-ID ist eindeutig (unique) und bleibt auch bei Änderung der Ortsbezeichnung oder Ortsteilbezeichnung oder nach Änderung sonstiger Datenfelder während der ganzen Lebensdauer des Datensatzes erhalten.
Führen Sie beim erstmaligen Einpflegen von KilletSoft-Daten die eindeutigen Datensatz-IDs in Ihren eigenen Datenbeständen mit. Beim späteren Einpflegen eines Updates überführen Sie die aktualisierten KilletSoft-Datenfelder ganz einfach anhand der eindeutigen Datensatz-IDs und des im Datensatz enthaltenen Änderungdatums in Ihren eigenen Datenbestand. Überlegen Sie sich eine Strategie für neu hinzugekommene oder ungültig gewordene Datensätze, die Sie durch fehlende oder neue Datensatz-IDs im Update lokalisieren können.
As a standard the database tables are present in the file format CSV (Comma Separated Values). The used character set is ANSI. This format is used often and in most cases you can import the data directly into your own system. For example, you can process the data directly in MS-ACCESS or MS-EXCEL without further editing.
The downloadable freeware program CONVERT converts the available database tables into other data formats and character sets with the necessary sortings and selections. With the program for example CSV data can be converted into the SDF format (Simple Document Format) or into the dBase format. For the use of the data on different platforms it is possible to select between the character sets ASCII, ANSI, UTF8 and UniCode. Thus the import of the data in any database management system or file system will be possible.
For the import in MySQL or SQL databases the necessary "CREATE TABLE" script can be generated. Further the selection of the data on data fields and data records is possible. In addition the data can be sorted on base of the data fields. Data from several files can be joined to a common file.
Here you can have a look to some screenshots of the converter program.
If both database tables ORTREF and ORTTLREF or ORTGEM and ORTTLGEM were acquired, they can be joined to a common database table and sorted again by assistance of the freeware program CONVERT (download see below). In the database table then all towns / municipalities and urban districts are arranged among each other and sorted on the municipality key.
