TMN and FGT discuss two products by MetaCarta. The first one is Map Rectifier, an online raster data georeferencing and registration tool. The second one is GeoSearch News, from the press release: "GeoSearch News indexes an extensive collection of more than 1,400 national, international and local news sources every hour in addition to direct feeds from the Associated Press and Reuters. GeoSearch News provides users a single site on which they can learn what is happening now at any destination in the world." This is not the first similar tool, see related stories below.

The Google Earth Blog has an article with this new animated layer for Google Earth from NASA. Along with this layer, the GE Blog also points out a couple of other layers that NASA has recently released. Here is a summary excerpt of this layer from the blog : "The ionosphere is used to bounce radio signals over the horizon for long distance communication. But, when storms occur on the sun's surface they can mess up parts of the ionosphere and disrupt ionosphere-based communications."

The Earth Is Square blog informs us that there is a ray casting and line of sight implementation in WWJava by way of Patrick Murris's blog. Here is an excerpt from Patrick's blog : "It is a common issue to be able to find out where in the world does a line intersect the terrain surface. The WorldWind Java SDK allows to resolve the intersection from the eye point of view using the pick process - based on drawing objects in unique colors, but that does not help much when you need to compute such intersections from another perspective, like for line of sight calculations."
