Eye4Software Hydromagic is hydrographic survey software for Windows. It can be used to generare depth maps using a GPS or RTK receiver and an echosounder or fishfinder. After recording the sounding you can generate DTMs (Digital Terrain Models) depth contours 3D views and cross-sections.It offers various methods of calculating volumes of bassins ponds river sections and lakes.The software is capable of reading and writing most popular CAD GIS and nautical chart formats including: GeoTIFF Microstation DGN ARCINFO MapInfo MIFMID AutoCad DXF files IHO S57S63 Electronic Natutical Charts Google Earth KMLKMZ files and ESRI shapefiles.A wide range of map projections is build in. More then 5000 map projections are built in. In addition NTv2 NADCON and HARN correction grids are supported.The software is also able to calculate tide levels in real time by using a RTK receiver connected to the PC. Using the antenna height antenna offset and a geoid model the tide level is calculated and applied to the sounding resulting in a height values relative to the local vertical datum.When no map is available for your area you can use the build-in map downloading tool. Use OpenStreetMap Google Maps or Bing maps as background maps. Since this latest version the software can be used to collect and process dual frequency sounding data as well as additional sensor data such as magnetometer data or advanced data from echosounders like reflectivity or bottom-loss.Another big improvement is the use of shorelines. Shorelines can be used to add data collected near the shore to create islands or to clip your DTM data by just by specifying on which side of the shoreline the water is.For the people who want to perform their survey by using planned lines there is also good news: It is now possible to calculate a DTM or depth contours from multiple soundings or shorelines.
