ORTWIN is a program for the country-wide inquiry of the localities in Germany to find cities and towns, urban districts, postal zip codes, dialling codes, coordinates and elevations, landscape and climatic data and other urban data and also to perform perimeter searches and distance calculations.
City and Municipality Directory and Locality Research of the Federal Republic of Germany
ORTWIN is a program for the country-wide inquiry of the cities and towns, localities, postal codes and dialling codes in Germany. It finds postal zip codes, dialling codes, coordinates and ground level elevations. The program determines municipal codes, local center points, car license codes, topographic maps, Unlocodes and much more. It arranges localities hierarchically into the structures Federal State, Administrative District, Rural District, town, municipality, local quarter and domicile. The program performs perimeter searches and distance calculations. It finds landscapes on different levels, natural units and climatic data like snow- and wind load zones and solar irradiations, sunshine duration and precipitation amount of all localities.
A program for the research of the German cities, municipalities and urban districts with postal codes, telephone codes and coordinates
In a radius around a localitie or around a postal code area covered localities and postal areas can be clearly represented by a comfortable perimeter search. They can also be arranged in a list, stored as a file and printed.
For the local inquiries and perimeter searches a data base with more than 125.000 geocoded localities is available. The program represents local data, determined by local inquiries and perimeter searches, in graphic overviews and data lists.
The program supports conversions between different Coordinate Systems and the distance calculation between localities. It calculates with UTM coordinates on the reference system ETRS89 (GRS80 ellipsoid) and with geographic coordinates on the reference system WGS84. It also uses Gauss-Krueger coordinates referenced to the Potsdam datum (DHDN, Bessel ellipsoid) and Google PlusCodes.
Towns and town quarters can be determined by entering already known data in the input fields of the data window, by clicking on overview maps or by selecting from sorted lists. For the calculation, the values listed here can be entered directly in the input fields of the program:
- UTM coordinates
- Geographical coordinates in DMS notation
- Geographical coordinates in decimal notation
- Gauss-Kruger coordinates
- Google Plus Codes (Open Location Code OLC)
- Place names or quater names
- Municipality ID (8-digit municipality key)
- New postal code
- Old postal code
- Telephone pre-selection
- Two place names for distance calculation
For selection from separate windows are available:
- Nationwide graphical overview map
- List with place names sorted by Federal States
- List with place names sorted by Administrative Regions
- List with place names sorted by Rural Districts
- Overview map with locations and place names in the location window
- Radial search map of places and quarters in close range
- Radial search map of places in the far range
- Radial search map of the postal delivery areas and postcodes
In addition, the program offers the services listed here:
- High precision coordinate transformations
- Searching places using leading characters or using sting-in-string search
- Determining the center coordinates of localities
- Finding the nearest locality to the current coordinates
- Finding a place adjacent to the current location
- Determining the old and new postal codes
- Determining the telephone pre-selections and the telephone book numbers
- Determining the exact distance between localities
- Determining the appropriate topographic map TK25 of the locality
- Determining the political hierarchy (town quarter / municipality part, town / municipality, Rural District, Administrative District, Federal Atate)
- Determining the landscape types, natural areas and climate data
- Determining of snow and wind loads and solar data
- File output and printing of the various radial search lists
- Printing all characteristic values belonging to the current location
- Printing all graphically views
- File output of all window contents in GIF and BMP files
- Electronic help file manual
- At any time case-related help from the electronic manual
- etc.
