Map Cruncher 3.0 Released
Need to crunch more tiles? Need to crunch them faster? Now you can! Download the latest version of Map Cruncher @ http://research.microsoft.com/mapcruncher. Here's a high-level list of new features:
• Far more robust -- major internal restructuring of the code makes things much more reliable
• Integrated with v4.0 MapControl API -- including support for the new 3D Virtual Earth!
• Transparency! Select background colors to be removed, or foreground colors to be kept, to allow maps to be better overlaid without losing underlying data
• "Auto legends" -- trace out the legend that appears on your map, and MC generates a web page so the legend pops up automatically when that source map is in the user's view
• Standard (sample) web page has integrated "Find" box, to let users search the yellow pages for items on the crunched map
• MC now emits bounds to the crunched.xml file describing where the mashup is defined. Prevents the web browser from requesting many non-existant tiles.
• Supports zoom levels up to 32
• Allows per-source-map specification of max zoom level to render, allowing better composition of maps with insets
• Easier on your disk: MapCruncher actually cleans the disk cache every so often
• Easier on your RAM: MapCruncher can now handle big mashups with many sourcemaps without thrashing virtual memory. It loads them into memory in turns in a sensible order
• Supports zoom levels up to 32 (approximately .03mm/pixel).
• Command-line rendering now supported, when invoked with a command line a .yum file parameter and the "-render" flag,
• The UI now allows you to reorder and remove sourcemaps and layers.
• Layer preview: click on a layer name, and the left panel shows a preview of the rendered layer. This is very helpful for putting the sourcemaps in the layer in the right order, and for tweaking the bounds of the sourcemaps.
• The minimum number of points required to lock is now only two. For many types of source maps, this can dramatically reduce the effort required to set up correspondences.
• The previous version performed image warping in the wrong space, so maps with large extent (particularly in extreme latitudes) rendered incorrectly. Alaska looks much better now.
• In the previous version, the cache or the rendered output could contain stale tiles based on out-of-date correspondences, giving confusing results that could only be fixed by manually flushing the cache and the rendered output. Fixed.
