To test the recent changes to my maptech library and to feature the omnipresent Geo-RSS feeds, i put together a simple yet powerful (at least i hope so) GeoRSS viewer. Features renders Atom 1.0, RSS 1.0 and RSS 2.0 supports W3C, Simple and GML feeds implements RSS 2.0′s TTL BTW, please add all georss-feed-urls you [...]

After some thinking on how to integrate the code for linearly-projected maps (zoomify …) and mercator-projected maps (almost all others) into a single AS3 model, i found a very good, easy and straight-forward architecture. The trick was to separate the coordinate conversion into two steps: linearisation and linear interpolation [...]
Doing another viewer for a 200+ maps project, i discovered that combining overview and detail maps in the same view, rendered the system unusable with only a few layers. Naturally i did some optimizations on the layer drawing code. This resulted in a dramatical performance improvement when combining large overview maps with detail maps in [...]
Just a quick note: received a request to use Maptech on microscopic images. Threw together an adapted client. The original demo is no longer available. Please see the enhanced demo. A server-side script scans for directories holding zoomify images, sorts them lexically and adds then to the client in sort order. Zoomify’s ImageProperties.xml is extended [...]
