What's New in Global Mapper SDK v1.27 (2008³â 5¿ù 2ÀÏ)

- Added GM_GenerateElevationGrid function to allow triangulating and gridding 3D vector layers to create

  a new elevation grid layer and optionally a layer holding the triangulation of the vector data.

- Added GM_AddCustomShader function to allow adding new custom shaders at runtime.

- Allowed creationg of 3D area and line features through the use of the mVertexElevList structure members when adding new area and line features to a custom vector layer.

- Made GM_LoadFlags_HideAllPrompts flag actually work.

- Added GM_LoadProjectionFromEPSGCode function to allow initializing a GM_Projection_t structure from an EPSG

  projection code.

- Added GM_SetLayerDescription function to allow changing the description for a layer.

- Added new GM_VectorExportFlags_Export3D flag for GM_ExportVector function to allow exporting 3D Shapefiles.

- Added new parameters to GM_AsciiFormatInfo_t structure for gridding both filled to the bounds of the layer and for ignoring zero elevations when gridding.

- Replaced mOpaque setting in GM_FontDef_t with new mBgMode member that allows more control over whether a label background is rendered opaque or transparent.

- Added support for loading Tiger 2007 Shapefiles with full attribution and automatic styling and type assignment from

  http://www.census.gov/geo/www/tiger/tgrshp2007/tgrshp2007.html.

- Added support for loading Vulcan3D triangulation files.

- Added support for loading OpenStreetMap (OSM) format vector maps.

- Added support for loading NITF data sets using JPEG2000 compression.

- Added built-in support for the MGA (Map Grid of Australia) projection.

- Added built-in support for the Aratu and Camacupa datums.

- Improved accuracy of OSGB36 datum conversions by using the OSTN02 tables.

- Made Bonne projection work properly when the origin latitude is in the Southern Hemisphere.

- Added support for decoding Albers Conic projections from Ozi .map files.

- Fixed problem with displaying the equator grid line when using the Van der Grinten projection.

- Fixed problems encoding and decoding Lambert Cylindrical Equal Area projection to/from GeoTIFF files.

- Added support for reading the track style information written to GPX files by the ExpertGPS software application.

- Fixed bug with enabling transparent colors for gridded elevation maps that made them disappear in some cases.

- Added support for parsing coordinate values that use commas rather than periods for the decimal separator character.

- When exporting new Polish MP format files, check the default attribute list for the type of a feature if the feature does not have a particular attribute in its own attribute list (this was already being done for the MP_TYPE attribute, but has now been extended to all supported MP attributes, like PERIOD for light points).

- Sped up exports to ECW and JPEG2000 files from map catalogs.

- Improved default elevation unit selection when loading multiple files so that it doesn't always default back to meters.

- Fixed problem with some grid line labels being drawn at strange angles.

- Made the bit depth be available in the metadata list for MrSID and NITF imagery.

- Added support for WMS servers using secure HTTP (i.e. https:// addresses).

- Improved accuracy of area calculations when using the Mercator projection.

- Write out "LOCAL" as the projection name when exporting ECW files using a projection that is not recognized for storage in ECW files.

- Added support for per-vertex elevations for area features from Shapefiles in all cases (previously only simple areas with no holes were supported).

- Improved great circle distance calculations by using the more accurate Vincenty algorithm.

- Fixed remaining problems loading portions of some Erdas Imagine .img grid files with floating point samples.

- Fixed problem with gap showing up between lines that end at the same location.

- Added built-in point types for bank and restaurant.

- Added built-in line type for invisible boundaries (such as those

  commonly found in Tiger/Line files).

- When loading KML/KMZ files, use the folder names from the files to automatically assign Global Mapper types if possible (i.e. if a matching type name exists).

- Added ability to specify water level in feet in addition to meters in the 3D viewer.

- Fixed problems loading some complex entities from DXF files.

- Fixed problems adding package files with multiple layers to map catalogs.

- Corrected placement of image files positioned using world files with rotation.
