I’ve had a few requests for the source code for the Bundle Browser prototype application.
You can download it here if you’re interested;
A small proof of concept, Bundle Browser lets you peek into your compact cache bundles and see individual tiles. It also gives you an indication of the percentage of populated tiles for the bundle and detailed tile information when previewing individual tiles. Continue Reading
Ever wondered how the version 10 “compact cache” works? Well so did I – so I did a bit of digging and this is what I found out.
On a current project we are caching an insane amount of national data, down to 1:250 is urban areas. The urban areas in particular have been very difficult to process due to their irregular shape – especially problematic are some coastal cities in New Zealand (look at Tauranga for example). After trialling irregular shapes (and failing) I tried extent envelopes of the urban areas. While this worked more successfully, some of the envelopes overlapped meaning tiles were being built twice. Some small coastal cities that sprawl along the coastline created large unnecessary envelopes which included rural and water areas which I didn’t want to cache. Continue Reading
