(C) Pavel Aristarhov, 2017, [email protected]
USAGE:
mpGen.exe <options>
options are:

silent <true|false>
Silent mode. If true, no messages will be written to console. Optional. Default is false

append <true|false>
If true, file will be appended with new data. Optional. Default is false

mpDestination <filepath>
Path to destination .mp-file. Required

mifSource <filepath>
Path to source MapInfo .mif-file. Required if no pgXXX options

pgConnectionString <string>
Connection string to PostgreSQL database. Required if no mifXXX options

pgQuery <string>
SQL query to PostgreSQL database returning table of geometry primitives and may be it's labels. Required if no mifXXX options

pgFieldNameGeometryWkt <string>
Field name with WKT in table which is result of SQL query (see pgQuery option). Required if no mifXXX options

pgFieldNameLabel <string>
Field name with label in table which is result of SQL query (see pgQuery option). Optional

reprojectGeoServerUrl <string>
Url to GeoServer WPS. For example, http://gis1:8080/geoserver/wps. Optional

reprojectGeoServerUser <string>
User name on GeoServer. Required for reprojectGeoServerUrl option

reprojectGeoServerPassword <string>
User password on GeoServer. Required for reprojectGeoServerUrl option

reprojectSourceSrs <string>
Source coordinate system to reproject from. For example, EPSG:28413. Required for reprojectGeoServerUrl option

reprojectTargetSrs <string>
Target coordinate system to reproject to. Optional. Default is ""EPSG:4326""

Recomended use WGS 84 coordinate system only. You have to reproject source MIF/WKT before convert it to MP/PFM by this tool or use reprojectGeoServerUrl option. Use GDAL/OGR to reproject. For example:
ogr2ogr.exe -skipfailures -t_srs ""EPSG:4326"" -f ""MapInfo File"" D:\\tmp\\dstw84.MIF D:\\tmp\\src.tab");
