Mapnik 忽略我的经纬度边界框

谁能看出下面这组命令有什么问题吗?每次我运行这些 image.png 时都是英国的图像,而不是我导出的 JOSM 地图。我猜数据库导入有问题,但输出提到它正在处理我的坐标和数据。

步骤:

1 - 从 JOSM 或 Merkaator 导出 .osm 文件。

2 - 使用以下命令导入 psql:

osm2pgsql -m -d gis -S ~/mapnik/default.style -b 103,1.3,104,1.4 ion.osm  -v -c

输出如下所示:

    marshall@ubuntu:~/mapnik$ osm2pgsql -m -d gis -S ~/mapnik/default.style -b 103,1.3,104,1.4 ion.osm  -v -c
osm2pgsql SVN version 0.66-

Using projection SRS 900913 (Spherical Mercator)
Applying Bounding box: 103.000000,1.300000 to 104.000000,1.400000
Setting up table: planet_osm_point
Setting up table: planet_osm_line
Setting up table: planet_osm_polygon
Setting up table: planet_osm_roads
Mid: Ram, scale=100

Reading in file: ion.osm
Processing: Node(25k) Way(3k) Relation(0k)
Node stats: total(25760), max(844548651)
Way stats: total(3783), max(69993379)
Relation stats: total(27), max(536780)

Writing way(3k)

Writing rel(0k)

Committing transaction for planet_osm_line

Sorting data and creating indexes for planet_osm_roads
Sorting data and creating indexes for planet_osm_polygon
Completed planet_osm_polygon
Completed planet_osm_roads
Completed planet_osm_point
Completed planet_osm_line

我可以看到传入的正确纬度/经度坐标,我不确定如何在数据库中验证这一点

3 - ./generate_xml .py --accept-none --dbname gis --symbols ./symbols/ --world_boundaries ../world_boundaries/

4 - ./generate_image.py

此时 image.png是英国的地图,而不是我指定的新加坡的地图。

谁能看出这有什么问题吗?这是 ubuntu 上的 mapnik 0.71

Can anyone see anything wrong with the following set of commands? Every time I run these image.png is a image of the UK and not the JOSM map I exported. I'm guessing there's something awry with the db import however the output mentions that it's processing my coords and data.

Steps:

1 - Exported a .osm file from JOSM or Merkaator.

2 - Imported into psql using the following command:

osm2pgsql -m -d gis -S ~/mapnik/default.style -b 103,1.3,104,1.4 ion.osm  -v -c

The output for this looks like:

    marshall@ubuntu:~/mapnik$ osm2pgsql -m -d gis -S ~/mapnik/default.style -b 103,1.3,104,1.4 ion.osm  -v -c
osm2pgsql SVN version 0.66-

Sorting data and creating indexes for planet_osm_polygon
Completed planet_osm_polygon
Completed planet_osm_roads
Completed planet_osm_point
Completed planet_osm_line

I can see the correct lat/lon coords being passed in, I'm not sure how to verify this within the database

3 - ./generate_xml.py --accept-none --dbname gis --symbols ./symbols/ --world_boundaries ../world_boundaries/

4 - ./generate_image.py

At this point image.png is a map of the UK, not Singapore which I have specified.

Can anyone see anything wrong with this? This is with mapnik 0.71 on ubuntu

找到了解决方案。

问题在于,generate_image.py 脚本不会从数据库读取数据,而是将其硬编码在内部。我不确定这背后的原因。

解决方案是手动编辑generate_image.py并更改相关行:

ll = (103,1.3,104,1.4)

Found the solution.

The issue is that the generate_image.py script does not read the data from the database but rather has it hardcoded inside. I'm not sure the reasoning behind this.

The solution is to edit generate_image.py manually and change the relevant line:

ll = (103,1.3,104,1.4)
