My theory was that somehow TileStache was translating it to another coordinate, outside the extract area. It uses the Modestmaps library, which translates to Slippy format ( //), same format used by Leaflet, TileStache and .įor instance, requesting 17/48561/74357.png on Kosmtik works, but the same tile returns as "blank" on TileStache. So I analyzed the requests Kosmtik was making (since these were working). Maybe there is something being "mistranslated" somewhere. Note that, when using Kosmtik, I was able to see the extract's name from as low as zoom 4. So even when browsing at the extract's location, it won't render correctly. All else, regardless of the zoom or location, renders to "blank". I suppose it only uses the planet/world shapefile, which was downloaded with the style. Interestingly, zoom 1 works (the one with 4 tiles). This means that accessing would have all tiles rendered on my server. Then, I've set up redirect rules from to using switcheroo, as described here. I've set up TileStache with Mapnik as the provider. Maybe I am generating tiles at the wrong location I've installed Kosmtik, and it worked fine! I was able to browse through the extract, inspect data, zoom in and out on all levels. Maybe some polygon/shape (the ocean's?) is covering another one. Maybe the generated style is invalid somehow. Here's what I've tried to fix this problem: Things I've tried
Same applies for incorrect DB information.Īnd here's the problem: every tile rendered by Mapnik is "blank" (blue-ish background, which is the defined background for OSM). I sort of unit-tested these changes: incorrect directories for shapefiles and symbols will raise an error when Mapnik tries to load the style.
Replace relative directory symbols/.svg to /full/path/symbols/.svg. 
Replace relative directory data/.shp to /full/path/data/.shp. Remaining connection info is grabbed from ~/.pgpass. Add the Postgres username (Parameter user on Mapnik's XML). I've made the following changes to the result: I have mapnik and python-mapnik 3.x, as well as carto 0.18.2.įrom the OSM's project.mml, I've generated my own project.xml using carto. The next step is rendering the tiles, and that's where I'm having trouble. I was able to view and query with all points, polygons, lines and roads. I verified the extract data is correctly loaded on the database by using QGIS. The hstore, style and tag-transform-script arguments are required for the proper utilization of OSM's style, as described here.Īs described on the openstreetmap-carto installation, I've also added custom indexes and downloaded the required shapefiles and fonts (except for the emoji ones). Osm2pgsql -G U -d -C 1000 -W -hstore -style openstreetmap-carto.style -tag-transform-script a In order to import the Sao Paulo extract, I use I've also added the postgis_topology and hstore extensions, which will be used later. I'm using 9.6 for the former, 2.3 for the latter. PostgreSQL and PostGIS are properly installed. MAPPROXY APACHE FULL
Since the full planet file is huge, I'm currently using a extract of Sao Paulo, which is good/small enough for testing.īefore I reach to the problem I'm having, I'll guide through the steps I took so far: What worked
Kosmtik - Map GUI for development/debugging. In order to import and style OSM data, I'm using Postgres + Postgis - For storing, transforming and processing GIS data. My goal is to serve planet-wide maps with OSM data on my own servers. Import .I'm new to the fascinating GIS world, and I've been researching the whole topic for the past few days. Add a launcher classĬreate a file called Main.java in your src/main/java/launch directory and put the following in it: package launch The appassembler plugin generates a launch script that automatically sets up your classpath and calls your main method (created below) to launch your application. If you use this technique for an application that doesn’t use JSPs then you can just include the first 3 dependencies. The last 3 entries are only required for applications that use JSP files. This pom.xml defines the dependencies that you’ll need to run Tomcat in an embedded mode.
