isolining package for ActionScript 3

A week or so back I wrote about a package I ported/modified to create the Delaunay triangulation in Flash with a few AS3 classes. As I noted there, such a triangulated irregular network (TIN) allows us to interpolate isolines — lines of constant value (aka isarithms, commonly called contours).
So, given a field of points [...]

pixelArea

I thought of this about a year ago, while implementing a dot density map in wiscMapper, but never needed to use it until recently. You see, as I noted recently here, to create a dot density map in Flash, it is typical to create random points within the bounding coordinates of the polygonal feature [...]

shapefiles / projections in Flash / AS3

Below is linked a little teaser from my recent experimentation with loading shapefiles.

indiemaps.com/shapefile

In the above, the work of loading the shapefiles is mostly done by the Vanrijkom classes I spoke of earlier. When I wrote before, I was more interested in loading shapefiles with PHP, and using Flash Remoting to pass in the shapefile [...]

loading shapefiles: actionscript3 or php?

I’ve recently become interested in loading shapefiles into Flash applications. Doing so opens up many possibilities.

Cartograms
Projections
Flash-based GIS

Perhaps best of all, it may mean that, for simple mapping tasks, I could do without ArcGIS altogether. I could load a shapefile into my Flash application, project it into one of dozens of projections, zoom into [...]

the hydrologic dashboard: on the road to a USGS statistical viewer

This summer, I was hired by David Hart, the coastal GIS specialist for UW Sea Grant to build a dashboard for viewing streamflow statistics in the Fox/Wolf rivershed here in Wisconsin.
Given the dashboard approach, I wanted to create something very aesthetically pleasing, flexible, and easy to use. For the data display, I coded a [...]
