[mkgmap-dev] [Patch v1] addr:interpolationFrom GerdP gpetermann_muenchen at hotmail.com on Sun Dec 7 13:53:45 GMT 2014
Hi all, attached is a 1st try to implement the evaluation of the addr:interpolation tag. In some areas this is heavily used, so it really improves address search. addr-interpolation-v1.patch <http://gis.19327.n5.nabble.com/file/n5826523/addr-interpolation-v1.patch> The implementation is straight forward: before style evaluation - check for tag addr:interpolation, make sure the value is one of "odd","even", or "all" - if the way has two or more nodes with addr:housenumber=* and addr:street=*, the way is a candidate for the interpolation and a tag mkgmap:node-ids is added to the way to be able to find them later after style evaluation: - for each pair of housenumber nodes : calculate the positions of the interpolated housenumbers and generate a node containing the housenumber and streetname I am not sure what to do with partly invalid data, e.g. a way with addr:interpolation=odd in combination with more than two nodes, the last having an even number. The current implementation will generate odd nodes for all valid pairs in that way. Effect: When searching for an address, it is more likely that you will not be pointed to a much higher or lower number. I did not notice an increase of img size. I assume in a few areas the additional calulations may require more CPU or memory, but the effect should be rather small.
