Voilà! We have excellent, correct OziExporer. In the same way I don’t understand the transverse mercator projection, since I read that Rijksdriehoeksmeting uses a stereographic projection. To be honest, I don’t understand where the false northing and the scale factor come from. In the template we use the transverse mercator projection, with central meridian at 5.387633333 degrees, a scale factor of 0.999907900 and false easting and northing of 155000 resp -5316592 meter.
#Oziexplorer map format how to#
Fortunatelly I found an article of an anonymous author describing an how to calculate Bessel 1841 coordinates out of RD coordinates. map file it calculates and fills in the RD and Bessel 1841 coordinates.
#Oziexplorer map format software#
Hence the software generates the map files: based on the RD coordinates provided in the PDOK Excel file and a template. Map Projection, Transverse Mercator,Pol圜al,No,AutoCalOnly,No,BSBUseWPX,No These settings are used for detecting adjacent maps in OziExporer and by Ozi Map Merge for the map outline! The coordinates are latitude/longitude coordinates according to the Bessel 1841 map datum (and not WGS84) for Rijksdriehoeksmeting! Gee… it took me a hell of a time to find this out! The coordinates are Rijksdriehoeksmeting (RD) coordinates (easting, northing) In the excerpt below it is printed in red. These points are used by OziExporer for getting the projection right. The OziExporer map files contains calibration data in two places: Refer to the read-me on Github describing how to proceed. The software takes the excel sheet delivered by PDOK describing the maps, including the calibration, and generates the. To get things the way I want I wrote a small Java program, available on Github. Also the result after merging multiple maps shows white spaces between the mpas. However on closer look we find slight deviations of about 10 m. After this the result looks fairly nice in OziExplorer. However, we need to change ‘ AMERSFOORT‘ to ‘ Rijksdriehoeksmeting‘ and ‘ Stereographic‘ to ‘ (PST) Polar Stereographic‘ in order for Ozi explorer to understand it. map files as datum setting ‘ AMERSFOORT‘, projection ‘ Stereographic‘ and the correct projection setup. The TOP25raster maps use EPSG:28992 coordinate system (Amersfoort/RD new). png file together with all kind of calibration files. A directory /output is created in the source directory in which the map files are converted to.
MAPC2MAPC creates a batch file MAPC2MAPC.bat and executes it. The tool must be bought.Ĭhoose ‘ Batchbuilder‘. Here it ends… Atempt 2: almost thereĪ method that works is conversion using the tool MAPC2MAPC. However I found this method to present maps with incorrect calibration data. Within a blink of an eye the map files are generated and placed in the Map File Path. However, this is not supported, so we choose ‘ Map Projection‘ to be ‘Mercator’ and press ‘ Ok‘. For ‘ Map Projection‘ we need ‘Transverse Mercator’. Select ‘ Image File Path‘ and ‘ Map File Path‘ to be the folder where the tif files are. Select ‘ Import map‘ -> ‘ All DRG Maps on a CD or in a Folder‘. OziExplorer seems to be able to do the job for us. map filesĪfter downloading the raster files from PDOK and extracting the tif files we end up with 490 GeoTIFF (.tif) files.įirst step is to create the. The GeoTIFF format is an image tif format that contains geo information. As an example we take the Basis Registratie Topografie (BRT) Top25raster 1:25.000 maps of the Netherlands that can be downloaded from PDOK and we will create an ozfx4 map covering the entire Netherlands. This page describes how to create Oziexplorer maps from GeoTIFF, including map merge. I still find Oziexplorer an excellent and versatile program for navigation, despite of the many, many apps relying on on-line maps.
