Hi folks, This is potentially a developer list question but I'm posting it to the user list to cast a wide net...
I'm working on an application which will work with a number of different types and sources of data including raster layers (as geotiff files), vector features (mostly as shapefiles), and layers where the value at a point is calculated on demand (aka 'analytical coverages' I think). I want the application to be able to treat all of these data sources as if they were rasters having the same cell dimensions and bounds. However, I want to avoid having to create new raster versions of the the non-raster data. This latter requirement is to do with runtime performance - the app is a simulation where the locations which need to be sampled in each layer, or even whether a given layer needs to be sampled at all, are unknown before-hand and the layers are potentially big. I'm thinking of this as a gridded facade or view of the data, similar in spirit to the JAITools VectorBinarize operation which takes a Geometry object and presents it to clients as if it were a binary raster. Essentially what I need (I think) is a continuously valued version of that. Before I go off and write such a thing I wonder if anyone can point me to an existing solution, not necessarily using GeoTools, which either does the above or is similar enough to act as a starting point. I'd rather it didn't involve database applications, although if there is a particularly easy approach that does I'd be keen to hear it.
