[R-sig-Geo] mapview with custom tiles

2016-09-21 Thread Marcel Stadelmann
Hello, Is it possible to use mapview with custom tiles without the predefined basemaps? In leaflet it is possible with the addTiles() function and a url (urlTemplate). It should work something like: library(mapview) mapview(gadmCHE)@map %>% addTiles(urlTemplate = 'http://localhost:8000/tiles8/

[R-sig-Geo] Geostatistics on geometric network

Dear list members, I'm working with electric measurements that were taken on pipelines. These are spatio-temporal data whose spatial domain is not Euclidean, because the pipelines form a geometrical network. Has any work been done before to study this kind of data? Best regards, Roelof Coster

Marcel, no for mapview and I am 99% certain also no for leaflet. Though mapview will render large vector data sets (tested for up to 3 million points or line/polygons vertexes). This is, however, not very flexible (e.g. no coloring by attribute etc.) and will not be compatible with any other l
