Data Description Data Specification Screenshots Download Geo Data German Streets Download Data Converter CONVERT Prices Geo Data German Streets Order Geo Data German StreetsStreet coordinates or also called street section coordinates are meaning the summary of several postal house addresses to an averaged position in the coordinate system on street or street section basis. The street coordinates are to be used with applications, which are developed to assign street oriented address groups positions in the form of coordinates. By Geo Coding streets or street sections become cartographically representable.
Street-exact geo data are on the one hand less expensive than the high resolution house-exact geo data, on the other hand they are more exact than the economically priced administrative geo data.
The possible field of application is very various. So e.g. own address lists can be enriched with geo references and visualized on suitable map material. The application scope reaches from information systems and navigation services, geo marketing, telecommunications and UTMS based services up to web applications and tasks of the public utilities, emergency services, security forces and delivery services. Another point of interest can be the establishing relationships between data derived from different hierarchies and levels. For example, it could be desirable to know to which federal state, administrative district and city a postal address belongs to.
The coordinates of the streets are present as geographic coordinates, UTM coordinates and Gauss-Krueger coordinates.
Geographical coordinates in degree notation are particularly suitable well for searches with Google Earth.
Here is as an example an Internet URL with coordinates from the "Geo Data German Streets", which can represent the location of Killet Software Ing.-GbR:
http://maps.google.com/maps?ll=5.976,6.45088.
The first value behind the identifier "ll" (lat / lon) is the geographical latitude, then the geographical longitude follows.
The shown URL can be inserted directly into the address field of the browser to represent a map cutout on the screen.

The data base tables "Geo Data German Streets" can be licenced economically for the Federal States of Germany or for completely Germany. Other compositions on administrative or postal units are possible. So the street coordinates can be arranged e.g. for a district or for a city / municipality or for a postal area. Please contact us, if you need the geo data in another composition.
The free test data, downloadable of the Internet, contain only a small, randomly selected representative excerpt from the original tables of the Federal States of Germany.
The test data may be used for test purposes only.
A commercial use of that data is not permitted.

The geo data offered here are in high quality and are present in different coordinate and reference systems. They are constantly updated by an internationally active geo data manufacturer and they are subject to a continuous quality control. The street-exact geo data are used in many mobile navigation systems.
Detailed information and hints to the use of the geo references can be found in the files of the download or in the detailed Data Specification.

The coordinates are present as geographic coordinates, as Gauss-Krueger coordinates and as UTM coordinates. Because the UTM coordinates and the 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(GK_E_CENT_1 - GK_E_CENT_2) difNorth = abs(GK_N_CENT_1 - GK_N_CENT_2) distance = sqrt(difEast * difEast + difNorth * difNorth) with GK_E_CENT_1: Easting of the first coordinate GK_N_CENT_1: Northing of the first coordinate GK_E_CENT_2: Easting of the second coordinate GK_N_CENT_2: Northing of the second coordinate abs(): Absolute value function sqrt(): Square root function distance: Distance in meters as result Formula for the distance calculation with UTM coordinates: difEast = abs(UTM_E_CENT_1 - UTM_E_CENT_2) difNorth = abs(UTM_N_CENT_1 - UTM_N_CENT_2) distance = sqrt(difEast * difEast + difNorth * difNorth) with UTM_E_CENT_1: Easting of the first coordinate UTM_N_CENT_1: Northing of the first coordinate UTM_E_CENT_2: Easting of the second coordinate UTM_N_CENT_2: Northing of the second coordinate abs(): Absolute value sqrt(): Square root distance: The result is the distance in meters
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 (LON_DEC1,LAT_DEC1) and the longitude and latitude of the second point (LON_DEC2,LAT_DEC2) 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 = LON_DEC1 * PI / 180
Lat1r = LAT_DEC1 * PI / 180
Lon2r = LON_DEC2 * PI / 180
Lat2r = LAT_DEC2 * PI / 180
with
LON_DEC1: Longitude of the first point in degree notation
LAT_DEC1: Latitude of the first point in degree notation
LON_DEC2: Longitude of the second point in degree notation
LAT_DEC2: 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 (3,14...)
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.
distance = 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
distance: 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 TRANSDAT 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.

First the database tables are present in a standard file format (dBase, ASCII / OEM character set). They can be imported directly into MS-EXCEL, MS-ACCESS and in Borlands dBase.
The downloadable freeware program CONVERT converts dBase formatted database tables into other data formats with the necessary characteristics and selections.
With the program for example dBase data can be converted into the SDF format (Simple Document Format) or into the CSV format (Comma Separated Value).
For the use of the data on different platforms it is possible to select between the character sets ASCII / OEM and ANSI / WINDOWS.
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.
