Hi Joris, thanks for testing. The severe messages were introduced with the latest patches from Ticker: http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=4167 The added source in Subdivision.java: if (w <= 0) { // think can get this from empty/unbounded maps log.error("Subdivision neg width ", w, "min=", area.getMinLong(), "mid=", longitude, "max=", area.getMaxLong(), "shift=", shift, "mask=", mask, "@", getCenter()); w = 0x7fff; } @Ticker: I don't know why we have those new messages?

Like the first version it adds the tag mkgmap:cache_area_size to the POI generated for polygons, but now also for POI generated for multipolygons. It also changes the value in the tag so that it is rounded to 1/1000 , so instead of e.g. "1211.34554234542" you'll get "1211.346" when you evaluate style function area_size() or this special tag. I guess nobody is interested in the precise value, but I did not want to remove all decimals. For example small buildings can have values below 1. I think the additional computations are no problem and the rounding reduces the additional memory needed. A compiled binary is here: http://files.mkgmap.org.uk/download/431/mkgmap.jar If I hear no complains I'll commit this patch on sunday.

I'll have a closer look reg. the side effects of the patch today.

In both situations it looks like its processing the points file first, then the lines and then de polygons. I don't; know if that's the common order. In your post form 30-9 you wrote that you use a dirty trick which causes possible extra memory consumption. Probably for that reason it never ended up in the main branch? Gr Joris Your post from 30-9-2017 says ================================================================================================= [mkgmap-dev] mkgmap:area2poi in combination with area_size() From Gerd Petermann GPetermann_muenchen at hotmail.com on Sat Sep 30 06:10:01 BST 2017 Hi Joris, I see no easy way to calculate the value on demand, but the function area_size() sets a tag mkgmap:cache_area_size when called for the first time. The attached patch uses this feature for a rather dirty trick. It calls the functionn before the node for the POI is generated, therefore the new tag is also copied to the node. So, you can use something like mkgmap:area2poi=true & mkgmap:cache_area_size > 1000 {do something ...} Disadvantage: The area size is calculated for all polygons, and additional memory is needed to store the value as the tag is added to the polygon way and the POI. BTW: The current code calculates and stores the value like this: mkgmap:cache_area_size="45.771240234375" I assume it would be good enough to store the rounded value as mkgmap:cache_area_size="46" A compiled binary can be found here: http://files.mkgmap.org.uk/download/358/mkgmap.jar Please let me know if this works for you.

I don't even understand how the POI can have the mkgmap:cache_area_size tag. The tag is added by the code that handles multipolygons and by the style function area_size, which only works with ways. My current understanding is that the POI is generated before the evaluation of the style, so I don't see a way that the tag is assigned by mkgmap. I assume that you used the same input files and options for the above results?

April 2018 22:39:40 An: Development list for mkgmap Betreff: [mkgmap-dev] area_size() function to be used in points file Hello Gerd A while a go (30-9-2017) you made a patch to make the usage of the area_size() function available in the points-file through the mkgmap:cache_area_size value. I used it to only display names and symbols on bigger area's to avoid cluttering. In the latest releases up to 4165 you mentioned fixes with 'area_size()' being not yet branched and some others which are branched. I lost the overview a little bit. I tested the special build of 30-9-2017 which does make the mkgmap:cache_area_size value available in the points file. (Example 1) and compared it to the mkgmap build 4165 (Example 2) which does not. Does this mean this feature is not branched or can I achieve a similar result else way?
