Update: now includes Mars and Moon. 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… Read More »
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… Read More »
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… Read More »
Recently i updated the mapTech demo to show 3 layers at once. Please be sure to adjust the 3 sliders at the bottom to set the upper 2 layers alpha value. Next step will be a drag & drop enabled kit to build customized layer sets of both static image/map and dynamic symbolic/charting data.
Update: See the FlexMap demo. Combine all possible map sources. Update: Recently the performance with multiple layers was dramatically improved. Please see the multi-layer demo. For years we’ve been using a heavily modified Zoomify image component for our mapping products. We started off at flash6 with an as1-component, incrementally modified it to understand coordinates, added… Read More »
