Issue on generating pbf file for water(ocean) layer from Natural Earth shape file #70

Closed arunkmp closed 9 years ago

arunkmp commented 10 years ago

Actually i wants ocean (water polygons) in map.

Initially tested using shape file http://data.openstreetmapdata.com/water-polygons-split-3857.zip it works fine. But at low zoom level i produce pbf file with higher size.

so i prefer to go Natural Earth for low zoom level(0-8) using shape file http://www.naturalearthdata.com/http//www.naturalearthdata.com/download/10m/physical/ne_10m_ocean.zip it generating pbf but not showing ocean in browser.

For your reference tileinfo from openstreetmapdata

layer: water version: 1 extent: 4096 keys: [1]FID values: [34706]0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56... feature: 1 type: Polygon tags: 0,1 geometries: 9,0,7012,106,0,22,0,114,0,42,0,0,0,82,0,138,0,36,0,0,0,118,0,176,0,200,0,238,0,14,15...

tileinfo from Natural Earth

layer: water version: 1 extent: 4096 keys: [2]featurecla,scalerank values: [2]Ocean,0 feature: 1 type: Polygon tags: 0,0,1,1 geometries: 9,4096,4096,10,0,0,15 feature: 2 type: Polygon tags: 0,0,1,1 geometries: 9,4096,4096,10,0,0,15,9,0,0,10,0,0,15,9,0,0,10,0,0,15,9,0,0,10,0,0,15,9,0,0,10,0,0,15,9,0,0,10,0,0,15,9,0,0,10,0,0,15,9,0,0,10,0,0,15,9,0,0,10,0,0,15,9,0,0,10,0,0,15,9,0,0,10,0,0,15,9,0,0,10,0,0,15,9,0,0,10,0,0,15,9,0,0,10,0,0,15,9,0,0,10,0,0,15,9,0,0,10,0,0,15,9,0,0,10,0,0,15,9,0,0,10,0,0,15,9,0,0,10...

see in Natural Earth same data 10,0,0,15,9,0,0 repeating again and again and also extent 4096 also showing in geometries.
